Comparing gradient methods

In a university project, I compared gradient methods for multiclass logistic regression with my project team.

The problem

We wanted to compare how different update and step-size choices affected accuracy and runtime.

My contribution

  • Co-authored the implementation and report.
  • Compared full-gradient and block-coordinate methods.
  • Ran experiments on synthetic data and MNIST using NumPy and PyTorch.

Evidence & scope

The repository includes the algorithms, experiment setup, and accuracy and runtime comparisons.

What came out of it

A documented comparison of optimization methods under the same experiment setup.

A comparative implementation and report, available in the public repository.
