As I mentioned in the other post, the curiosity bots can help with this.

They're rewarded by exploring, not by values in game.

Maybe alone they're not enough, but in conjunction with other things, I bet we could beat Zelda. I had the bot exploring enough to find the first dungeon of LoZ.

This person https://github.com/pathak22/noreward-rl and his curiosity AI https://github.com/openai/large-scale-curiosity can do some cool stuff.

I used it to train an AI to play Mario Kart ( https://www.youtube.com/watch?v=A8oSnh0M864 )

I also had it playing The Legend of Zelda (got as far as finding the first dungeon, but with more power, I'm certain it could explore the whole map.).

I made a seq2seq chatbot with Matrix/Riot, the python-api implementation (https://github.com/matrix-org/matrix-python-sdk) and https://github.com/tensorlayer/seq2seq-chatbot:

Here it is: https://www.youtube.com/watch?v=rCggOcKZn-c

(There's a fun interaction at 25:52)

Yeah, topology and weights. It's highly subject to initial conditions. You almost need another NEAT network to evolve the initial conditions. I believe it's turtles all the way down.

The article is from last year but it's still extremely valuable and interesting.

Exploring this topic is currently my primary hobby. Specifically, I've been using OpenAI's retro (Sonic, Contra, Mario, Donkey Kong and, more recently FZero) and comparing the ancient NEAT with more fashionable stuff like DQN, PPO, A3C and DDPG.

With my extremely limited experience, NEAT seems to outperform all of these other algorithms. I believe the advantage is the potential for strange/novel network structure.

And the best part is that NEAT doesn't require a powerful GPU.
