Decomposing reverse-mode automatic differentiation

no code implementations20 May 2021 Roy Frostig, Matthew J. Johnson, Dougal Maclaurin, Adam Paszke, Alexey Radul

We decompose reverse-mode automatic differentiation into (forward-mode) linearization followed by transposition.

Automatically Batching Control-Intensive Programs for Modern Accelerators

no code implementations23 Oct 2019 Alexey Radul, Brian Patton, Dougal Maclaurin, Matthew D. Hoffman, Rif A. Saurous

We present a general approach to batching arbitrary computations for accelerators such as GPUs.

Early Stopping is Nonparametric Variational Inference

1 code implementation6 Apr 2015 Dougal Maclaurin, David Duvenaud, Ryan P. Adams

By tracking the change in entropy over this sequence of transformations during optimization, we form a scalable, unbiased estimate of the variational lower bound on the log marginal likelihood.

Gradient-based Hyperparameter Optimization through Reversible Learning

2 code implementations11 Feb 2015 Dougal Maclaurin, David Duvenaud, Ryan P. Adams

Tuning hyperparameters of learning algorithms is hard because gradients are usually unavailable.
