Question 1These are all methods of dealing with unbalanced classes EXCEPT:1 pointDownsampling.Mix of in-sample and out-of-sample.Mix of downsampling and upsampling.Upsampling.
Solution
The correct answer is "Mix of in-sample and out-of-sample." This is not a method used to deal with unbalanced classes. The other options, Downsampling, Upsampling, and a mix of downsampling and upsampling, are all techniques used to balance classes in a dataset.
In-sample and out-of-sample are terms used in statistics and machine learning to describe whether data was used in the training phase (in-sample) or in the testing phase (out-of-sample). They are not techniques used to balance classes.
