Skewness Definition DeepAI

WebbIn machine learning, skew refers to an imbalance in the distribution of the label (target variable) in a training dataset. A training dataset is said to be skewed if the distribution of its target variable is asymmetric around its mean value - that is, it is not balanced and some values are more highly represented than other values.
