“ Wafer level faults probably won't matter though - neural nets are resistant to a few missing or wrong weights.”

Brain science people “love” traumatic brain injury cases because it can help explore what happens when bits of the “brain wafer” get damaged. We’ve learned a lot from such things.

I wonder if people are intentionally “destroying” parts of the model weights to learn more about what happens? Like could you strategically wipe a gig of the model so it’s “all zeros” and see what happens?

I have to wonder

Of course tampering with chunks or nodes in the NNs is a way to study the "spawned" (through gradient descent etc.) configuration and "reverse-engineer the black box" to get "AI transparency".

Anthropic published an important work around one year ago.

This is called mechanistic interpretability. There is lots of fascinating insights already since you can do basically everything down to the neuron or weight level thousands of times. The human brain is many orders of magnitude harder to make sense of.
