Background Model Energy Knowledge Estimation Generation vs. Evaluation Physics-based vs. Knowledge-based Knowledge Local vs. Global (Non-local): mean force Estimation RMSD, GDT_TS

Introduction

Methods Local Geometry: 7-mer fragments Nonlocal Geometry Solvent effects Weights training

Local

Ignoring Smooth Kernel

Non-local: A pairwise potential Ignoring regularization

Modeling Solvent Effects

Complete Potential

Discussion

Chao’s comments This potential can’t describe the first phase of folding. Hierarchical potential.
