Gappy (Giuseppe Paleologo)(@__paleologo):It’s very likely that a fruit fly (~150k neurons, ~100m synapses) could do basic portfolio construction for a fundamental PM— orthogonalizing 100 alphas to a few important factors and scaling them. The problem is training on the job. But with enough bananas, I am optimistic we could get it done.
