Is AlphaFold RL?
hardAnswer
- No — AlphaFold uses supervised learning on protein structure database (PDB).
- Loss: predicted vs true atomic coordinates.
- However, related work uses RL for de novo protein design (RFdiffusion + reward from AlphaFold2 verifier is RL-adjacent — search over sequence space with structure-quality reward).
- Interview trap: distinguish protein STRUCTURE prediction (SL) from protein DESIGN (RL / search).
Check yourself — multiple choice
- Yes, RL
- Structure prediction is supervised on PDB; protein DESIGN uses RL-adjacent search with AlphaFold as verifier — trap: don't conflate structure prediction and design
- Random
- Only imitation
AlphaFold = SL structure prediction; protein design uses RL/search with AF as verifier.
