Description: Meta-features are attributes that summarize the characteristics of a dataset, providing a compact and meaningful representation of the information contained within. These features can include descriptive statistics such as mean, median, and standard deviation, as well as more complex properties that capture patterns and relationships within the data. In the context of anomaly detection, meta-features are crucial as they enable algorithms to identify unusual behaviors by comparing the characteristics of new data with previously established meta-features. By utilizing meta-features, anomaly detection models can enhance their accuracy and efficiency, focusing on the most relevant dimensions of the data, reducing noise, and facilitating the identification of anomalous patterns. In summary, meta-features act as a bridge between raw data and machine learning algorithms, optimizing the anomaly detection process and improving systems’ ability to adapt to new situations and datasets.
