WitrynaFor learning algorithms, this leads to great difficulty, as they are biased towards the majority class. But at the same time, minority classes may generate useful knowledge. The concept of designing a smart system for handling skewed distribution to overcome the bias is known as learning from imbalanced data . WitrynaImbalanced data typically refers to a classification problem where the target classes are not represented equally. For example, you have a 2-class (binary) classification …

WitrynaHowever, existing methods are usually data-driven, which rarely consider the costs associated with fundus image collection and annotation, along with the class-imbalanced distribution that arises from the relative scarcity of disease-positive individuals in the population. WitrynaImbalanced data in machine learning refers to the situation where the distribution of classes in the target variable is not equal. This can occur in both binary and multiclass classification problems: in a binary classification problem, one class may have significantly more instances than the other class.
