Binned entropy python

Web1) The data is pretty noisy (and around 2000 points), so binning should help cut down the error bars a bit. The actual regression function is a reasonably simple Normal Equations … WebOne way to make linear model more powerful on continuous data is to use discretization (also known as binning). In the example, we discretize the feature and one-hot encode the transformed data. Note that if the bins are not reasonably wide, there would appear to be a substantially increased risk of overfitting, so the discretizer parameters ...
