Previously I have managed to train the model to reach 200, but after implementing a few changes, it dropped back to random policy and stalled on around 165.

Yesterday I spent my night setting up MXNet for solving Space Invaders. Initially, I thought it would not take me too long as I have been previously configuring data providers for MXNet in Julia, but it resulted in the opposite.

Finally! I did it! I’ve been struggling for some time trying to make DQN work and could not succeed.
Today I have managed to make it work and solve CartPole from OpenAI gym using DQN. You know what the problem was? Size of my neural network!
