This passage discusses the concept of data mining, which is the process of extracting valuable, previously unknown, and comprehensible information from large datasets for organizational decision-making. However, the author notes that there are several challenges associated with mining data from large datasets, including data redundancy, non-specific attribute values, incomplete data, and outliers.

An outlier is defined as an observation that deviates significantly from other observations, raising suspicions that it was generated by a different mechanism. Identifying outliers can provide useful and meaningful knowledge and has applications in various fields such as climatology, ecology, public health, transportation, and location-based services.

The author mentions that while there have been some recent studies on outlier detection for large datasets, most existing studies focus on algorithms based on specific backgrounds. In contrast, there is comparatively less focus on the approach to outlier identification.

The main focus of this paper is to discuss outlier detection approaches from a data mining perspective. The underlying idea is to research and compare the mechanisms of these approaches to determine which approach is better based on a specific dataset and different backgrounds.
