moves(Abraham, Higdon, et al. , 2018). The survey
article on change point identification in historical data
is briefly represented in this paragraph. Change
points, or sudden changes in data patterns, are usually
employed to indicate state transitions and have a wide
range of uses, such as human activity detection,
healthcare inspection, climate analysis, and voice and
depict processing. It also describes potential hurdles
for the field's advancement and presents criteria for
analysing these algorithms. Researchers as well as
professionals interested in the analysis of time series
and its various applications will find this thorough
overview to be pertinent(Aminikhanghahi, and,
Cook, 2016).
It examines the privacy restrictions of Bitcoin in
an academic context by examining both simulated
and actual transactions. Approximately 40% of the
user database could be recreated even with the usage
of suggested privacy precautions. This paper provides
an in-depth assessment of Bitcoin's privacy concerns,
highlighting its problems with
transparency(Androulaki, Karame, et al. , 2013). The
research used a vector Auto regression (VAR) model
to examine what macroeconomic factors affected
Ghana's exchange rates between 2000 and 2019. Real
GDP granger causes exchange rate initiatives,
whereas other variables have indirect effects,
according to an analysis of the broad money supply
(M2), lending rates, inflation, and real GDP. The
analysis was supported by data from the Ghana
Statistical Service, World Development Indicators,
and the Bank of Ghana. In order to lower inflation,
boost output, and eventually stabilise the exchange
rate through higher GDP, the study suggests measures
that lower lending rates and the money supply.
(Antwi, Issah, et al. , 2020). A pair of methods for
effectively detecting segment neighbourhoods—
contiguous residue sets with common features—are
presented in the current investigation. These methods,
which support a variety of models and fit functions
which includes maximum likelihood and least
squares, estimate the model parameters essential
define these communities and establish their
boundaries. They provide versatility for a range of
applications by iteratively detecting significant
sequence properties. When one technique was used to
the influenza virus's haemagglutinin protein, a break
in the powerful heptad repeat structure suggested a
possible mechanism for conformational shift. This
demonstrates how useful the algorithms can be in
researching structural biology (Auger, Lawrence, et
al. , 1889). The increasing market value of digital
currencies and their potential to consolidate power
and lessen global dominance are examined in this
article. It draws attention to the erratic nature of
virtual currencies and the need for accurate
techniques for predicting their prices. Incorporating
characteristics like stock market the capitalisation,
trade volume, distribution, and delivery indicators, a
new forecasting model is presented. The method
shows how effective the model is in predicting the
values of digital currencies by using active LSTM
networks to examine benchmark datasets and long-
term trends. The results highlight how sophisticated
machine learning methods might enhance
cryptocurrency prediction(Biswas, Pawar, et al. ,
2021).
Wild Binary Segmentation (WBS), a novel
technique for estimating the quantity and positions of
authority of many change-points in data, is introduced
in this study. WBS uses a random globalisation
mechanism, which allows it to detect small jump
magnitudes and closely spaced change-points without
the need for a window or span parameter, in contrast
to normal binary segmentation. This method
preserves implementation simplicity and
computational efficiency. With suggested parameter
defaults, the authors suggest two stopping criteria:
thresholding and a reinforced Schwarz information
criterion. The R function wbs on CRAN offers WBS's
implementation, and comparative analyses
demonstrate its superior performance (Fryzlewicz, ,
et al. , 2014). According to the paper's assessment of
RNN models for cryptocurrency price prediction,
GRU has the lowest MAPE scores and is the most
precise for Bitcoin, Litecoin, and Ethereum. To
increase predicting accuracy, future research suggests
merging social media and trade volume (Hamayel,
and, Owda, 2021). The paper evaluates deep learning
models for predicting bitcoin prices, such as CNN,
LSTM, and BiLSTM, and concludes that they are
inadequate for capturing market complexity. To
increase forecasting accuracy, it recommends
investigating cutting-edge algorithms and feature
engineering.
Using significant supply and demand-related
aspects from blockchain data, this study investigates
the use of Bayesian Neural Networks (BNNs) for
modelling and forecasting Bitcoin price time series.
When comparing BNNs to other benchmark models,
empirical research shows how successfully they
anticipate prices and account for the extreme
volatility of Bitcoin. This demonstrates how BNNs
can be used to increase the forecasting accuracy of
price of bitcoin(Jang, Lee, et al. , 2017).
