Yea the surrogate gradient stuff works ok, others that are decent 1) STDP variants, especially dopamine modulated STDP (emulates RL-like reinforcement) 2) for networks < 10M params, evolution strategies and similar zero-order solvers can work well operating directly on the weights 3) variational solvers can work if you structure the net + activations appropriately

I see, thanks. Why did you choose to use SNNs for your application instead of conventional ANNs? Are you using a neuromorphic chip?

No neuromorphic chip. Main reason is interpretability.

Oh, I haven't heard about using SNNs for interpretability. I thought they were on the same level as ANNs. Sorry for all the questions, but can you elaborate on how they're more interpretable?

The spiking events should be much more sparse and therefore probably easier to interpret.
