Goal:
Key concepts: gradient descent, rugged landscapes, metastable states, Hessian matrices, random matrix theory, landscape’s complexity.
Langevin, Activation
Problem
Consider the REM. Assume that the configurations are organised in an hypercube of connectivity : each configuration has neighbours, that are obtained flipping one spin of the first configuration
