Web31 de mar. de 2024 · It’s completely possible that a category will show up in the test set, but not in the training set. Your model would have no idea how to handle that category because it has never “seen” it before. One way to address these problems is by engineering new features that have fewer categories. This can be accomplished through binning … Web14 de abr. de 2024 · Binning : Binning methods smooth a sorted data value by consulting its “neighborhood”, that is, the values around it. Regression : It conforms data values to a function. Linear regression involves finding the “best” line to fit two attributes (or variables) so that one attribute can be used to predict the other.
