[D] From classification to regression and some physics analogies

Hello,

Here is:

https://www.researchgate.net/publication/360541388_From_Classification_to_Regression_A_Note_on_Deodata_Predictors

The paper describes how to adapt a set of classification algorithms in order to perform nonlinear regression.
The algorithms are described with simple numerical examples.
In the "Field Sampling Density" section, the described operation is akin to estimating the strength of a field.
I am interested in your opinions.
Thanks.
