Lunchbox ML

Hi everyone I have started to learn ML concepts but have a starting trouble in how to use this package can you help me out with some examples of ML application with lunchbox.
for instance the linear regression node didn’t give me expected output even after training with 100 sample data.
Also wondering why iam not able to find a single tutorial for ML via dynamo please do share if you have some materials.!

@saju_autodesk, LunchBox has an “Extra” folder with sample files, including those using machine learning:
%appdata%\Dynamo\Dynamo Revit\1.3\packages\LunchBox for Dynamo\extra

Also look for examples @ provingground
