Often we have some smoothness guarantees on the data, the space of the data is not populated so densely or the dimensionality can be reduced(a big part of machine learning research). Perhaps the best example for this is the space of all …

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.
