Publication number: 20210042606Abstract: Some embodiments are directed to a neural network comprising an iterative function (z[i+1]=ƒ(z[i], ?, c(?)). Such an iterative function is known in the field of machine learning to be representable by a stack of layers which have mutually shared weights. According to some embodiments the stack of layers may during training be replaced by the use of a numerical root-finding algorithm to find an equilibrium of the iterative function in which a further execution of the iterative function would not substantially further change the output of the iterative function. Effectively, the stack of layers may be replaced by a numerical equilibrium solver. The use of the numerical root-finding algorithm is demonstrated to greatly reduce the memory footprint during training while achieving similar accuracy as state-of-the-art prior art models.Type: ApplicationFiled: August 5, 2020Publication date: February 11, 2021Inventors: Shaojie BAI, Jeremy Zieg KOLTER, Michael SCHOBER
