#machinelearning #neuralnetworks
Algo1 and Algo2 are two famous #DeepRL algorithms, here tested
on the Half-Cheetah #opengym benchmark.

Many papers in the litterature compare using 4-5 random seeds,
like on this graph which suggests that Algo1 is best.

Is this really the case?
However, more robust statistical tests show there are no differences.

For a very good reason: Algo1 and Algo2 are both the same @openAI baseline
implementation of DDPG, same parameters!

This is what is called a "Type I error" in statistics.
