Looks like a buggy implementation.

The learning rate was too large. It should be around 0.001. Now everything looks great ! But I still don't know why this happens when the learning rate is large.

These artefacts look like a bug on the gpu, you sometimes see this if for example you use uninitialised variables or have data races in a compute or pixel shader.

I don't use gpu or c++. I only use julia programming language and this is just part of my master's thesis.

I've implemented the algorithm in the paper "Learning the light transport the reinforced way". What is the name of this effect and how should I solve it?
