  Backpropagation J.G. Makin February 15, 2006 1 Introduction The aim of this write-up is clarity and completeness, but not brevity. Feel free to skip to the “Formulae” section if you just want to “plug and chug” (i.e. if you’re a bad person). If you’re familiar with notation and the basics of neural nets but want to walk through the derivation, just read the “Derivation” section ...

  a multilayer neural network. We will do this using backpropagation, the central algorithm of this course. Backpropagation (\backprop" for short) is a way of computing the partial derivatives of a loss function with respect to the parameters of a network; we use these derivatives in gradient descent, exactly the way we did with linear regression and logistic regression. If you’ve taken a ...

  Why neural networks • Conventional algorithm: a computer follows a set of instructions in order to solve a problem. Fine if you know what to do….. • A neural network learns to solve a problem by example. - Provides a mapping from one space to another. - The input space could be images, text, genome sequence, sound. - The output is often a classification (dog, cats, guinea pigs). • In ...

  benchmark algorithm for ML. 16.1 Neural Networks with smooth activation functions We recall that given a graph (V,E) and an activation function σwe defined N (V,E),σ to be the class of all neural networks implementable by the architecture of (V,E) and activation function σ(See lectures 5 and 6). Given a fixed architecture a target function f ω,b∈N (V,E),σ is parametrized by a set of ...

  Backpropagation is the central algorithm in this course. It’s is an algorithm for computing gradients. Really it’s an instance of reverse mode automatic di erentiation, which is much more broadly applicable than just neural nets. This is \just" a clever and e cient use of the Chain Rule for derivatives. We’ll see how to implement an automatic di erentiation system next week. Roger Grosse ...
