This repo is from my Master's degree thesis work develped at Addfor s.p.a
I used PlaNet to prove that model-based DRL can overcome the model-free algorithms in terms of sample efficiency. My implementation of PlaNet is based on the Kaixhin one, but I reach better results. I also experiment with a regularizer based on DAE to reduce the gap between the real and the predicted rewards.
The company asks me to note publish that feature, but you can find all the explanations in my blog article (you can also contact me).
