products. This combination not only enhances the

adaptability and flexibility of insurance products, but

also provides new business opportunities for

insurance companies. Machine learning models help

insurance companies more accurately predict and

quantify risks by analyzing historical claim data and

market data, thereby optimizing insurance pricing

strategies. The diverse uses of data mining techniques

within the insurance sector, encompassing activities

like evaluating risks, identifying fraudulent activities,

and examining underwriting processes, all play

crucial roles in the evolution of index-based insurance

products.

chapter discussing the application of machine

learning in insurance pricing; Chapter 2 will analyze

the current situation and challenges of insurance

claim detection; Chapter 3 will explore the

combination of index insurance and machine

learning. Each chapter will provide detailed case

studies to demonstrate the effectiveness and potential

of machine learning techniques in practical

applications.

2 THE APPLICATION OF

MACHINE LEARNING IN

INSURANCE PRICING

In the insurance industry, insurance pricing is the core

link, which is directly related to the financial health

and market competitiveness of insurance companies.

The key to insurance pricing lies in accurately

predicting future risks and payout probabilities. With

the development of big data and machine learning

technologies, insurance companies can now use these

advanced tools to analyze historical claim data,

thereby more accurately predicting payout trends and

optimizing pricing strategies. This change not only

improves the accuracy of pricing, but also provides an

opportunity for insurance companies to maintain their

advantage in fierce market competition.

Insurance is a financial mechanism aimed at

managing economic uncertainty by diversifying risks

(Kaffash, Azizi, Huang, & Zhu, 2019). Insurance

companies traditionally rely on generalized linear

models to handle data modeling of claim frequency

and severity (Spekkers, Kok, Clemens, & Ten

Veldhuis, 2014). However, with the successful

application of machine learning in multiple fields,

these techniques have begun to be widely adopted by

insurance companies for improving risk assessment

and pricing models. Machine learning models can

learn from historical claim data and predict payout

trends, providing insurance companies with a new

tool to improve pricing accuracy and efficiency.

Utilizing machine learning techniques allows

insurance firms to forecast the likelihood of incurring

losses with greater precision, which in turn mitigates

the issue of information imbalance within the sector

(Eling, Nuessle, & Staubli, 2022).

2.1 Flexible data processing methods

Traditional claim prediction methods typically

involve fitting the frequency and severity of claims to

a known probability distribution function and using it

to predict future claims (Poufinas, Gogas,

Papadimitriou, & Zaganidis, 2023). But this method

relies on accurate fitting of claim data and may not

capture all complex patterns in the data. Machine

learning provides a more flexible approach that can

handle more complex data patterns, including non-

linear relationships and high-dimensional data.

Machine learning models, including supervised

learning, unsupervised learning, and reinforcement

learning (Paruchuri, 2020), are being used to develop

more advanced claim prediction systems. These

models can automatically identify key patterns in data

and be used to predict claim probabilities and

amounts, thereby helping insurance companies

optimize their funding preparation and pricing

strategies. Spekkers et al. (2014) used regional

aggregated claims data provided by Dutch private

property insurance companies, including damages

related to rainwater, such as damage caused by

rainwater infiltration through roofs and ground

flooding entering buildings. The study used decision

tree analysis to investigate the influencing factors of

rainfall related damage, which can handle nonlinear

relationships, high-order interactions, and missing

data. By constructing a decision tree model,

researchers can identify the factors most relevant to

claim frequency and average claim size. Research has

found that the frequency of claims is most correlated

with the maximum hourly rainfall intensity, followed

by real estate value, ground floor area, household

income, season (property data only), building age

(property data only), ownership structure (content

data only), and proportion of low rise buildings

(content data only). Nonetheless, the construction of

DAML 2024 - International Conference on Data Analysis and Machine Learning

586

a tree-based model that meets statistical standards for

predicting the typical claim amount was unsuccessful,

suggesting that the fluctuations in the typical claim

amount could be associated with factors that are

intractable to pinpoint on a regional level. Provided

more imaginative space for data collection work

(Spekkers et al., 2014).

2.2 Addressing Data Incompleteness

Missing data is a common issue when dealing with

historical data of insurance applicants (Rusdah &

Murfi, 2020). Traditional statistical methods typically

require estimation or interpolation of missing values,

but machine learning algorithms such as Extreme

Gradient Boosting (XGBoost) can directly handle

missing values without the need for interpolation

preprocessing beforehand. XGBoost can accurately

handle missing values through its sparse perception

segmentation algorithm. Investigations reveal that the

XGBoost algorithm, even without the application of

interpolation for data preparation, achieves a similar

level of precision to that of the model with

interpolation. This finding substantiates the

proficiency of XGBoost in managing data sets that

have missing entries. This ability makes machine

learning models more robust and capable of

extracting valuable information from incomplete

data. In addition, the application of machine learning

technology in processing climate data is becoming

increasingly widespread. Machine learning

algorithms are used to process climate data such as

precipitation, temperature, and soil moisture

(Eltazarov, Bobojonov, Kuhn, & Glauben, 2023).

Through spatial downscaling, the random forest

algorithm can refine coarse resolution climate data to

fine data with a resolution of about 5 kilometers,

which is crucial for assessing risks related to weather,

natural disasters, and other factors. The application of

this technology can help insurance companies assess

risks more accurately, especially when developing

index insurance products.

2.3 Reduce structural deviation

The unstructured nature of machine learning

algorithms helps reduce structural biases in

traditional models (A et al., 2020). These biases

typically stem from simplified assumptions and data

requirements of the model. Machine learning models

can adapt more flexibly to the true distribution of

data, thereby providing more accurate risk

assessments. This advantage is particularly important

in insurance pricing, as it can help insurance

companies quantify risk more accurately and set more

reasonable premiums. In addition, when evaluating

the performance of machine learning models, it is

necessary to consider using multiple performance

indicators to increase the transparency of the

modeling process, such as (Hanafy & Ming, 2021),

Accuracy, Error rate, Kappa, AUC (Area Under the

Curve), Sensitivity, Specificity, Precision, Recall, F1.

The application of machine learning technology in

insurance pricing provides a new perspective, which

optimizes insurance pricing by processing large

amounts of historical data, predicting payout trends,

and reducing information asymmetry. With the

advancement of technology, insurance companies can

expect more accurate and flexible pricing strategies to

adapt to the constantly changing market environment.

The development of these technologies not only

improves the pricing accuracy of insurance products,

but also provides insurance companies with stronger

market adaptability and competitiveness. Emerging

technologies such as federated learning have also

shown potential in personalized insurance pricing,

providing more accurate and personalized pricing

strategies while ensuring data privacy. With the

continuous exploration and application of these

advanced technologies in the insurance industry, we

have reason to believe that future insurance services

will be more intelligent, efficient, and user-friendly.

3 MACHINE LEARNING IN

CLAIM MANAGEMENT

Claim management is a core part of insurance

company operations, which directly affects the

financial stability and customer satisfaction of the

insurance company. In the insurance industry, timely

and accurate handling of claims is crucial for

maintaining company reputation and customer trust.

As machine learning technology progresses,

insurance firms are equipped with sophisticated tools

to enhance both the speed and precision of claims

management. This section will delve into the ways

machine learning assists insurers in making

significant strides in the detection of fraudulent

claims, the forecasting of claim amounts, and the

optimization of the claims process. Models powered

by machine learning, particularly ensemble

algorithms and deep learning architectures, have

shown remarkable efficacy in forecasting claims and

uncovering fraud. These models are adept at handling

extensive data sets and discerning pivotal elements

that influence the likelihood of claims (A & B, 2021).

Machine Learning in Insurance: Enhancing Pricing, Claim Detection, and Index Insurance Innovation

587

M. K. Severino and Y. Peng provided a macro profile

of fraudsters based on real data in the property

insurance field: approximately 60.14% of fraudsters

are male; 48.16% of fraud cases are "premature

claims", which refer to claims made shortly after the

start of the insurance contract; 52.81% of fraudsters

are unmarried; 79.95% of the insurance amount is

used for electrical damage or theft claims; The

average age of fraudsters is 41 years old; 72.61% of

fraud cases involve new insurance policies rather than

renewed ones; In fraud cases that have been detected

but not yet confirmed in court, the average claim

amount for fire/lightning/explosion insurance is the

highest.

3.1 Detecting Fraudulent Claims with ML

Claim fraud detection is an important issue in the

insurance industry, as it not only affects the financial

health of insurance companies, but may also erode the

interests of honest customers. Machine learning

algorithms, especially deep learning structures, have

shown great potential in identifying fraudulent claims

(Spekkers et al., 2014). These algorithms can learn

the characteristics of fraudulent behavior by

analyzing patterns and anomalies in historical claim

data. For example, algorithms such as logistic

regression, XGBoost, C50, and random forest have

been proven to be highly effective in predicting the

probability of claims occurring in car insurance

(Hanafy & Ming, 2021). In addition, big data

technology can efficiently process and analyze

massive medical insurance claim data, thereby

identifying abnormal patterns and potential

fraudulent behavior (Subrahmanya et al., 2022).

Through in-depth analysis of claim data, it can be

discovered that there are unconventional claim

patterns, such as abnormally high claims, frequent

claims by individuals or medical institutions, and

diagnostic and treatment patterns that do not align

with common medical practices. In fact, many

insurance companies have increasingly adopted

patterns and anomaly detection to automatically

detect fraudulent claims (Eling, Nuessle, & Staubli,

2022), which not only improves detection speed but

also enhances accuracy.

3.2 Predicting Claims Amounts Using ML

Models

Accurate prediction of claim amount is crucial for

insurance companies' fund management and

customer satisfaction. Machine learning models can

predict claim amounts by analyzing historical claim

data, thereby helping insurance companies better

prepare funds. Machine learning models can also

dynamically adjust prediction strategies based on the

complexity and variability of claim data to adapt to

the constantly changing claims environment. Many

health and car insurance companies have applied

predictive analytics to data from connected devices

and developed new innovative, personalized usage

based insurance products (Eling, Nuessle, & Staubli,

2022).

In addition, machine learning methods have also

provided new avenues for claim prediction (Poufinas,

Gogas, Papadimitriou, & Zaganidis, 2023), which can

help improve traditional claim processing processes.

For example, using machine learning methods,

particularly random forest regression and

classification algorithms, to predict flood insurance

claims in New York State. Combining flood

insurance claim records from the National Flood

Insurance Program (NFIP) with hydrological and

demographic data to improve the accuracy of flood

exposure maps, and taking into account socio-

economic factors such as the proportion of minority

residents, property values and ages, and political

differences in electoral districts. The research results

indicate that combining socio-economic data can

improve flood exposure estimation, especially at the

regional level of population census. These data

significantly enhance the predictive ability of the

model and provide a new perspective for

understanding flood risk (A, J. K. et al.,2020) .

3.3 Automating and Optimizing Claims

Processing

Streamlining and refining the claims process not only

boosts operational efficiency but also contributes to

an elevated level of customer satisfaction. The

application of machine learning technology in this

area includes automated claim classification,

identification of abnormal claims and fraudulent

behavior, as well as reducing human intervention. In

specific operations, there are many innovations in

feature selection methods. The Chi-squared test

serves as a statistical technique for assessing the

relationship between various features and the

outcome variable, prioritizing features according to

their pattern of occurrence. Recursive Feature

Elimination (RFE) operates as an encompassing

strategy that determines the most relevant subsets of

features by iteratively eliminating them, often paired

with classification algorithms like logistic regression.

Meanwhile, tree-based feature selection functions as

an intrinsic approach that leverages the inherent

DAML 2024 - International Conference on Data Analysis and Machine Learning

588

capability of tree-based models, such as Extra Trees,

to evaluate the significance of features. These feature

selection techniques help reduce the dimensionality

of the dataset, improve the predictive accuracy of the

model, and reduce computation time. Using

appropriate feature selection methods can not only

streamline the feature space, but also improve

algorithm performance. Research (Spekkers et al.,

2014) has found that the random forest algorithm

performs best after feature selection, especially when

using tree based feature selection methods. In

addition, certain specific customer characteristics

(such as age, BMI, number of steps, number of

children, smoking status, and region) are significantly

associated with health insurance and travel insurance

claim behavior, and these findings can help insurance

companies better understand and predict claim

patterns.

Another study on car insurance fraud detection

used the Boruta algorithm for feature selection

(Aslam, Hunjra, Ftiti, Louhichi, & Shams, 2022).

Researchers were able to identify the most influential

features for fraud detection - "faults," "basic

policies," and "policyholder age," and applied three

prediction models (logistic regression, support vector

machine, and naive Bayes) to develop fraud detection

mechanisms. For each feature, the Boruta algorithm

calculates its importance score in the random forest

and compares it with a random feature (i.e. a

randomly selected unimportant feature in the feature

set). If the importance score of a feature is

significantly higher than that of a random feature,

then that feature is considered important and retained

in the model. If the score is lower than the random

feature, then this feature is considered unimportant

and is excluded in subsequent iterations. When all

features have been evaluated and the importance

score has stabilized, the iterative process terminates.

Ultimately, the Boruta algorithm will output a list of

features that are considered to be most influential in

predicting the target variable (in this study, fraud

detection). Boruta algorithm identified the 9 most

important features for detecting car insurance fraud

through the above steps, including "vehicle age",

"vehicle category", "number of days of accident",

"policyholder age", "gender", "marital status",

"accident liability party", "insurance type", and "basic

insurance policy". These features are then used to

construct machine learning models to improve the

accuracy of fraud detection. These features can also

serve as a reference for subsequent car insurance

fraud detection projects.

Incorporating machine learning technology into

the analysis of insurance claims not only enhances the

speed and precision of the claims handling process

but also aids insurance firms in more effectively

managing risks and allocating resources optimally.

With the continuous advancement of technology,

future insurance companies can expect more

intelligent claim processing systems to adapt to the

constantly changing market environment. Accurate

cost estimation can help health insurance companies

and an increasing number of healthcare delivery

organizations plan for the future and prioritize the

allocation of limited nursing management resources

(Ul Hassan et al., 2021). By utilizing machine

learning technology, insurance companies can

provide more personalized and efficient services

while reducing operating costs and improving

customer satisfaction.

4 INDEX INSURANCE

INNOVATIONS WITH

MACHINE LEARNING

Machine learning technology provides strong support

for the design, pricing, and risk assessment of index

insurance products. By utilizing machine learning

models, insurance companies can more accurately

predict and quantify risks, thereby providing

customers with more reasonable insurance products.

As technology continues to evolve, forthcoming

index insurance offerings are poised to become

increasingly smart and tailored, assisting both

insurers and policyholders in more effectively

managing the financial repercussions of severe

weather occurrences.

4.1 ML-Driven Innovations in Index

Insurance

Index insurance, as a risk management tool, focuses

on providing compensation by linking it to indices

such as weather and natural disasters, thereby

avoiding adverse selection and moral hazard issues in

traditional insurance (Nguyen, Mushtaq, Kath,

Nguyen-Huy, & Reymondin, 2024). This form of

insurance determines compensation through

objective weather indices, which are highly correlated

with actual losses and provide more timely and cost-

effective compensation (Zhang et al, 2022). Machine

learning methods can be used to fuse information

from different sensors and data sources to improve

the accuracy and robustness of the exponential

insurance model. The application of machine learning

technology, especially in video and image analysis,

Machine Learning in Insurance: Enhancing Pricing, Claim Detection, and Index Insurance Innovation

589

provides an early warning system for the

development of index insurance products, which is

crucial for managing and predicting weather related

risks (Eling, Nuessle, & Staubli, 2022).

4.2 ML in Risk Assessment and Product

Development

Machine learning models assist insurance firms in

forecasting and quantifying risks with greater

precision by examining past claims and market

information, which in turn allows for the refinement

of insurance pricing strategies. The diverse uses of

data mining within the insurance sector, including

evaluating risks, identifying fraud, and analyzing

underwriting, are all crucial elements in the

development of index insurance products (Spekkers

et al., 2014). Machine learning technology provides

strong support for the design, pricing, and risk

assessment of index insurance products. We used

historical weather data and crop yield data from

Illinois, USA, including 72 weather indices such as

precipitation, temperature, dew point temperature,

maximum and minimum temperatures, and water

vapor pressure deficit. Innovatively applying neural

network models to design weather index insurance

contracts, learning from high-dimensional and

nonlinear weather data through machine learning

methods to improve the risk management capabilities

of insurance products. Research has found that

compared to insurance products based on traditional

linear models, neural network models can

significantly improve farmers' utility and determine

equivalent wealth (CEW), reduce underlying risk,

and demonstrate better performance in test samples

(Chen, Lu, Zhang, & Zhu, 2024).

By utilizing machine learning models, insurance

companies can more accurately predict and quantify

risks, thereby providing customers with more

reasonable insurance products. With the continuous

advancement of technology, future index insurance

products will become more intelligent and

personalized, helping insurance companies and

policyholders better cope with the financial

consequences of extreme weather events. Eltazarov et

al. (2023) utilized optical bands and indices recorded

in NOAA AVHRR climate data, as well as SRTM

digital elevation model data, as input features for

machine learning models to train models to predict

climate parameters with finer spatial resolution.

Research has found that in most cases (70%), weather

index insurance crafted with climate data that has

been spatially refined through machine learning

techniques has shown enhanced effectiveness in risk

mitigation, with these enhancements being

statistically significant. Notably, insurance products

tailored using downscaled temperature and rainfall

data have demonstrated superior performance in

diminishing inherent risks and amplifying the

potential for risk reduction. In addition to common

agricultural related indices such as weather and yield,

parameter insurance has also launched products in

disasters such as fires, floods, and typhoons. Myoung

and Sunghai (2020) have proposed a new Korea Fire

Risk Index (NKFRI) that covers all types of buildings

and factories, particularly those designated by South

Korean law as exceeding 3000 square meters and

other specific buildings. It improves the accuracy of

fire risk assessment by optimizing the weights of each

component. NKFRI considers various variables

(components) related to fire occurrence, which are

divided into different modules and categories, such as

basic hazards (such as building age, number of floors,

structure, scale, fire load, etc.), ignition hazards (such

as fire sources, gas facilities, hazardous material

facilities, power facilities, etc.), and process hazards

(only applicable to factories). The research results

indicate that Deep Neural Network and NKFRI

provide superior performance in fire risk prediction

and management compared to traditional Korea Fire

Risk Index (Choi & Jun, 2020).

4.3 Future of Health Index Insurance with

The development of index insurance products in the

health industry is still in its infancy, but with the

development of big data and artificial intelligence

technology, this field has shown great potential and

necessity. With the popularity of social media and

smartphone applications, real-time monitoring of

personal health data has become easier. Data obtained

from electronic health records (EHR), electronic

medical records (EMR), and electronic patient

records (EPR), as well as data collected through

social media and healthcare related smartphone

applications, provide strong data support for the

development of insurance products (Subrahmanya et

al., 2022). These technologies can monitor individual

health parameters, provide real-time data for index

insurance products, help insurance companies assess

risks related to specific events, and develop and price

health index insurance products based on this. When

developing index insurance products for the health

industry, insurance companies can use big data and

machine learning technologies to improve the

accuracy of risk assessment and achieve personalized

pricing strategies. For example, by analyzing

DAML 2024 - International Conference on Data Analysis and Machine Learning

590

individual health data, insurance companies can

customize insurance costs for each customer, thereby

making premium rates more equitable (Hanafy &

Ming, 2021). In addition, machine learning models,

especially ensemble methods and deep neural

networks, have demonstrated superior performance in

predicting claims and fraud detection (A & B, 2021),

which helps to improve the speed and efficiency of

health insurance payouts.

Although the development of index insurance

products in the health industry is feasible, there are

also some challenges in their promotion. For

example, the existence of underlying risk is the main

reason for the consistently low demand for index

insurance (Sun, 2022). To overcome these challenges,

insurance companies can take the following

measures:

 Personalized risk assessment: With the

development of IoT (Internet of Things)

technology, insurance companies are able to

collect a large amount of personal health data.

Combined with machine learning algorithms,

this data can be used to create more refined

personal health profiles. On the premise of

respecting the privacy rights of the insured,

insurance companies can analyze detailed

personal health data, including data from

wearable devices such as smartwatches and

fitness trackers. In addition, the integration of

genetic technology has opened up new

possibilities for personalized risk assessment.

Genetic information and genetic testing results

can be used to predict the incidence rate of

certain insured diseases, enabling insurance

companies to provide more accurate pricing of

insurance products.

 Product innovation: Machine learning models,

especially deep learning techniques, are

helping insurance companies develop new

index insurance products. These products may

be based on specific health conditions or

treatment outcomes, for example, by analyzing

an individual's genetic information to predict

the risk of developing specific diseases and

designing insurance products accordingly. In

addition, the combination of wearable devices

and health management services provides new

directions for insurance product innovation.

Insurance companies can provide insurance

products related to health trackers, encouraging

users to reduce premiums through healthy

lifestyles. Such products can not only attract

customers with strong health awareness, but

also help reduce the insurance company's

claims risk.RegTech: RegTech is the field of

utilizing new technologies to meet regulatory

requirements. In response to escalating

regulatory demands, insurance companies must

manage and scrutinize substantial volumes of

data to remain compliant. Machine learning can

help insurance companies automate and

optimize these processes, improving

compliance efficiency. For example, by using

data analysis and machine learning techniques,

insurance companies can identify and report

potential fraudulent behavior faster, while also

better understanding and predicting market

trends, thus preparing and responding to

potential risks in advance.

5 CONCLUSIONS

The application of machine learning technology in

insurance pricing, claim detection, and index

insurance has brought significant changes to the

insurance industry. This article reviews how these

technologies can improve the efficiency and accuracy

of the insurance industry, and demonstrates the

potential of machine learning in the insurance

industry through theoretical analysis and literature

review.

In terms of insurance pricing, machine learning

technology analyzes historical claim data to enable

insurance companies to predict payout probabilities

more accurately, thereby achieving more refined

pricing strategies. The application of this technology

reduces the problem of information asymmetry and

improves the accuracy and efficiency of pricing.

Machine learning models are capable of handling

complex data patterns, including non-linear

relationships and high-dimensional data, providing

insurance companies with a new tool to improve

pricing accuracy.

The progress in claims detection is particularly

significant. The application of machine learning

technology has significantly improved the

intelligence level of claim detection. By analyzing

patterns and anomalies in claim data, insurance

companies can more effectively identify fraudulent

claims. The application of this technology not only

improves detection speed, but also enhances

accuracy, thereby protecting the interests of insurance

companies and honest customers. Machine learning

models, including supervised learning, unsupervised

learning, and reinforcement learning, are being used

to develop more advanced claim prediction systems.

In the field of index insurance, the application of

machine learning technology has demonstrated

tremendous innovation potential. By analyzing

climate data and optimizing risk assessment models,

machine learning provides insurance companies with

the opportunity to develop new insurance products.

These products can better adapt to market changes

and provide customers with more flexible insurance

solutions. Index insurance provides compensation by

linking it to indices such as weather and natural

disasters, thus avoiding the issues of adverse selection

and moral hazard in traditional insurance.

Although machine learning technology has brought

many benefits to the insurance industry, there are also

some challenges. Issues such as data privacy, model

transparency, and regulatory compliance require joint

efforts from insurance companies and regulatory

agencies to address. In addition, with the

development of technology, ensuring the fairness and

ethics of machine learning models is also an

important direction for future research. Insurance

companies need to ensure the security and privacy of

customer data while utilizing these technologies.

This review is based on existing literature and

theoretical analysis, and future research can further

explore the application effects of machine learning

technology in practical insurance business. Empirical

research can provide deeper insights and help

insurance companies better understand and apply

these technologies. In addition, interdisciplinary

research methods such as combining economics,

statistics, and computer science may bring new

perspectives and solutions to the insurance industry.

Future research should focus on how to integrate

machine learning techniques with the specific needs

of the insurance industry, as well as how to evaluate

and improve the effectiveness of these technologies

in practical applications.

The application of machine learning technology

in the insurance industry is a constantly evolving

field, providing opportunities for insurance

companies to improve efficiency, optimize risk

management, and innovate products. With the

continuous advancement of technology, insurance

companies need to constantly adapt and innovate to

fully utilize the potential brought by these

technologies. Future insurance services will be more

intelligent, efficient, and user-friendly, but at the

same time, attention needs to be paid to the challenges

and ethical issues brought by technology. Insurance

companies should actively explore how to integrate

machine learning technology into their business

processes, while ensuring that the implementation of

these technologies does not harm customer interests

or violate regulatory regulations.
