Machine learning user seeks advice on confounding variables in radar object classification

By PulseAugur Editorial · [1 sources] ·

A user on the r/MachineLearning subreddit is seeking advice on how to address a confounding variable in their object classification model. The model, which uses automotive radar point clouds, shows improved performance when using 'range' as a feature, but the user suspects it's learning a correlation between distance and object size rather than true class distribution. They are asking for methods to stress-test this hypothesis and suggestions on whether to exclude the 'range' feature despite the potential performance drop. AI
