PAWN: Piece Value Analysis with Neural Networks

Overview

Best-performing MLP and MLP+CNN piece value prediction models from PAWN: Piece Value Analysis with Neural Networks.

We define piece value as the difference in Stockfish evaluation between the original position and the position with that piece removed.

Models

MLP (MC-Large) — Best MLP model trained on Dataset MC-Large (6,925 Magnus Carlsen games, 11.7M piece value entries).
MLP (TF) — Best MLP model trained on Dataset TF (7,656 GM-level Classical games, 12.3M piece value entries).
MLP+CNN (MC-Large) — Best MLP+CNN model trained on Dataset MC-Large.
MLP+CNN (TF) — Best MLP+CNN model trained on Dataset TF.
