Web16 apr. 2024 · At its core a Hopfield Network is a model that can reconstruct data after being fed with corrupt versions of the same data. We can describe it as a network of nodes — or units, or neurons — connected by links. Each unit has one of two states at any point in time, and we are going to assume these states can be +1 or -1.

Web1.17.1. Multi-layer Perceptron ¶. Multi-layer Perceptron (MLP) is a supervised learning algorithm that learns a function f ( ⋅): R m → R o by training on a dataset, where m is the number of dimensions for input and o is the number of dimensions for output. Given a set of features X = x 1, x 2,..., x m and a target y, it can learn a non ...
