"derived mathematical expressions phase transitions discovered faster... .... Neural networks have already become quite good at detecting phase transitions”, says Arnold, “but how exactly they do it usually remains completely obscure.” To change that situation and shine some light into the “black box” of a neural network, Arnold and Schäfer looked at the special case of networks with an infinite number of parameters... time to calculate... as long as single training round of small network"
