Added a new script: mlp_activation_comparison.py

This script demonstrates the effect of different activation functions (relu, tanh, logistic) on a simple dataset using scikit-learn's MLPClassifier.
It helps visualize and understand how activation choices influence model performance.


Describe your change:

  • Add an algorithm?
  • Fix a bug or typo in an existing algorithm?
  • Add or change doctests?
  • Documentation change?

Checklist:

  • I have read CONTRIBUTING.md.
  • This pull request is all my own work -- I have not plagiarized.
  • I know that pull requests will not be merged if they fail the automated tests.
  • This PR only changes one algorithm file. To ease review, I will open separate PRs for separate algorithms.
  • All new Python files are placed inside an existing directory.
  • All filenames are in lowercase characters with no spaces or dashes.
  • All functions and variable names follow Python naming conventions.
  • All function parameters and return values are annotated with Python type hints.
  • All functions have doctests that pass the automated testing.
  • All new algorithms include at least one URL that points to Wikipedia or another similar explanation.
  • If this pull request resolves one or more open issues, the description above includes the issue number(s) with a closing keyword (e.g., Fixes #ISSUE-NUMBER).
