WebAug 18, 2024 · You can use explained variance score from Sklearn which gives the score of explained variance vs dimension of data. In statistics, explained variation measures the proportion to which a mathematical model accounts for the variation (dispersion) of a given data set. More the variation in the model, less it is prone to overfit and vice versa. Share WebFeb 25, 2024 · The curse of dimensionality in machine learning is defined as follows, As the number of dimensions or features increases, the amount of data needed to generalize the machine learning model accurately increases exponentially. The increase in dimensions makes the data sparse, and it increases the difficulty of generalizing the model. ...
