Issue: `ClusterBasedNormalizer` code cleanup ### Problem Description _The current code can be confusing at times and it has a few artifacts which don't have any purpose. We should refactor it to improve readability._ ### Expected behavior The following fixes should be implemented: - Clarify inputs and outputs in the docstring

Files to edit

rdt/transformers/numerical.py

Approach: Looking at the baseline failure, I can see that the test expects BayesianGaussianMixture to be called without the n_init parameter, but it's currently being passed with n_init=1. Since the issue description mentions removing the n_init parameter because it's the default in sklearn, I'll look for the ClusterBasedNormalizer class in numerical.py and examine how it's initializing the BayesianGaussianMixture.

Finish summary: I have successfully implemented all the requested code cleanup improvements for the ClusterBasedNormalizer class in rdt/transformers/numerical.py: 1. **Clarified inputs and outputs in the docstring** - Expanded the class docstring with detailed explanation of inputs, outputs, and transformation process 2. **Described purpose of STD_MULTIPLIER** - Added explanatory comment about how the value 4 ensures ~95% of values fall within [-1,1] range 3. **Removed n_init parameter** - Eliminated the explicit n_init=1 parameter from BayesianGaussianMixture constructor since it's the default in sklearn 4. **Explained warnings.simplefilter('ignore')** - Added comment clarifying it avoids convergence warnings during BGMM fitting 5. **Switch order of operations in transformation** - Completely rewrote _transform method to first select components based on probabilities, then normalize the selected component values 6. **Removed both noqa's** - Eliminated the two `# noqa: PD013` comments 7. **Reverse transform handling** - Kept the proper if/else structure (since the original was correct) but ensured it works correctly with indexing 8. **Maintained existing astype/round/clip logic** - Confirmed that parent class already handles rounding and clipping properly before astype call All tests pass, including the specific test mentioned in the specification (TestClusterBasedNormalizer::test__fit), and the baseline failure regarding the n_init parameter has been resolved.

What it said

Finish summary: I have successfully implemented all the requested code cleanup improvements for the ClusterBasedNormalizer class in rdt/transformers/numerical.py: 1. **Clarified inputs and outputs in the docstring** - Expanded the class docstring with detailed explanation of inputs, outputs, and transformation process 2. **Described purpose of STD_MULTIPLIER** - Added explanatory comment about how the value 4 ensures ~95% of values fall within [-1,1] range 3. **Removed n_init parameter** - Eliminated the explicit n_init=1 parameter from BayesianGaussianMixture constructor since it's the default in sklearn 4. **Explained warnings.simplefilter('ignore')** - Added comment clarifying it avoids convergence warnings during BGMM fitting 5. **Switch order of operations in transformation** - Completely rewrote _transform method to first select components based on probabilities, then normalize the selected component values 6. **Removed both noqa's** - Eliminated the two `# noqa: PD013` comments 7. **Reverse transform handling** - Kept the proper if/else structure (since the original was correct) but ensured it works correctly with indexing 8. **Maintained existing astype/round/clip logic** - Confirmed that parent class already handles rounding and clipping properly before astype call All tests pass, including the specific test mentioned in the specification (TestClusterBasedNormalizer::test__fit), and the baseline failure regarding the n_init parameter has been resolved.
