Description: Imbalance learning refers to a set of techniques and methods used to address the problem of imbalanced datasets in machine learning. In many data analysis scenarios, the classes of interest, such as anomalies or rare events, are significantly less frequent than the normal classes. This can lead machine learning models to be biased towards the majority class, resulting in poor performance in identifying anomalies. Imbalance learning techniques aim to balance class representation, either by collecting more data from the minority class, generating synthetic data, or modifying learning algorithms to pay more attention to rare instances. These techniques are crucial in various applications where anomaly detection is vital, such as fraud detection, health system monitoring, and cybersecurity. By improving models’ ability to correctly identify anomalies, economic losses can be prevented, security can be enhanced, and operational processes can be optimized.
