Theano automatic differentiation
WebAutomatic differentiation. Automatic differentiation is the weapon of choice of machine learning platforms such as Tensorflow and PyTorch. It works by deconstructing an expression into its computational graph consisting of basic operations and elementary functions, with well-known derivatives and then applying chain rule. WebAutomatic differentiation. In mathematics and computer algebra, automatic differentiation ( auto-differentiation, autodiff, or AD ), also called algorithmic differentiation, …
Theano automatic differentiation
Did you know?
WebJun 27, 2016 · By automatic differentiation I mean differentiation via the chain rule. What we do here is just break every formula into small piece, the we the only thing we need to do is just implement the differentiation for every single pieces, which is quite simple, than by calling the grad method one by one we can get the differentiation for the whole complex … WebOct 27, 2015 · But in practice most people use libraries like Theano that support auto-differenation of expressions. If you are for somehow forced to calculate the gradients yourself, you probably want to modularize different units and have your own version of auto-differentiation using the chain rule. We let Theano calculate the gradients for us:
