This is also what
@KordingLab and Greg and I meant with highly specific evolutionarily programmed “bootstrap cost functions” being the things brain would optimize if it does some powerful online optimization during organism lifetime a la DLShow this thread -
I think it is also obvious to
@tyrell_turing that this is the level of specificity of loss function evolution could build in for brain to optimize, if it “does DL” — things like this, but specific to brain area and developmental stage, and specific animal’s ethological needsShow this thread -
When one speculates about brain as some kind of DL type system, it does not mean having architecture or loss function similar to current systems: to me, it means a) powerful optimization alg. on during organism lifetime + b) many highly specific evolved loss fxn recipes like this
