Resolved! Debugging!

Hi ML folks, We are using Databricks to train deep learning models. The code, however, has a complex structure of classes. This would work fine in a perfect bug-free world like Alice in Wonderland. Debugging in Databricks is awkward. We ended up do...

If df_boston is a DataFrame, but you still face issues, try an alternative syntax: df_boston = df_boston.rename(columns={'zn': 'Zoning'}).Make sure df_boston is a proper DataFrame and you're using a recent version of Pandas.

How should I tune hyperparameters when fitting models for every item?

What's the difference between Normalization and Standardization?

Normalization typically means rescales the values into a range of [0,1].Standardization typically means rescales data to have a mean of 0 and a standard deviation of 1 (unit variance).
