Episode notes
PAC Learning's Breadth
- PAC learning, probably approximately correct, isn't just for computers; it's a broader epistemological goal.
- It suggests that in any prediction, the promise for a single case is weak, but strong when averaged.
Solving Induction
- Computer science has offered a solution to the philosophical problem of induction.
- It formalizes that probable approximate correctness is attainable even if absolute certainty is impossible.
Neural Nets' Rise
- In the 80s, neural nets weren't initially competitive due to smaller datasets.
- Their performance improved significantly with larger datasets, becoming more competitive.
