Abstract: In sensor network, data generated by various sensors deployed at different locations need to be analyzed in order to identify interesting events correspond to outliers. The presence of outliers may distort contained information. To ensure that the information is correctly extracted, it is necessary to identify the outliers and isolate them during knowledge extraction phase. In this paper, we propose a novel unsupervised algorithm for detecting outliers based on density by coupling two principles: first, kernel density estimation and second assigning an outlier score to each object. A new kernel function building a smoother version of density estimate is proposed. An outlier score is assigned to each object by comparing local density estimate of each object to its neighbors. The two steps provide a framework for outlier detection that can be easily applied to discover new or unusual types of outliers. Experiments performed on synthetic and real datasets suggest that the proposed approa ch can detect outliers precisely and achieve high recall rates which in turn demonstrate the potency of the proposed approach.
