# Comparing implementations¶

The following benchmarks compare different implementations of the same algorithm.

## Benchmarks around scikit-learn¶

Some benchmarks are available on PolynomialFeatures at Benchmark of PolynomialFeatures + partialfit of SGDClassifier.

## Benchmarks of toy implementations in C++, Python¶

The following benchmarks were implemented in other repositories. The first one measures differents way to write the dot product in C++ using a couple of processors optimization such as branching or AVX instructions.

The second one looks into the implementation of a logistic regression with python, C++ or C++ optimization provided by other libraries.

The next benchmark compares the gain obtained by playing a criterion for decision tree regressor.
