WebbOverfitting may happen when the model learns too much from too little data, so it processes noise as patterns and has a distorted view of reality. It's like if you were learning guitar, but only ever practiced one song. You’d get very good at it, but when asked to strum a new song, you’ll find that what you learned wasn’t all that useful. Webbsome nonasymptotic concentration phenomena in the Gaussian model. We note that in both of the models, the features are selected randomly, which makes them useful for studying scenarios where features are plentiful but individually too ``weak"" to be selected in an informed manner. Such scenarios are common in machine learning practice,
