  • $\begingroup$ 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. $\endgroup$ – bitWise Nov 6 at 20:53
  • $\begingroup$ 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. $\endgroup$ – PaulHK Nov 7 at 2:15
  • $\begingroup$ I don't use gpu or c++. I only use julia programming language and this is just part of my master's thesis. $\endgroup$ – bitWise Nov 7 at 10:13
