Definition of Imbalanced Datasets
Imbalanced datasets refer to datasets where the distribution of classes is significantly unequal. This imbalance can skew the learning process of AI models, leading to biased outcomes and inaccurate predictions. Typically, one class (the minority class) is underrepresented in comparison to the other class or classes (the majority class/es).
Challenges Posed by Imbalanced Datasets for AI Software
The inherent challenges of imbalanced datasets lie in the potential for AI models to prioritize the majority class, leading to suboptimal performance in recognizing and classifying the minority class. This can have serious repercussions, especially in critical domains such as healthcare, finance, and fraud detection.
