A Simple Baseline for Bayesian Uncertainty in Deep Learning Wesley J. Maddox 1Timur Garipov 2 Pavel Izmailov Dmitry Vetrov2;3 Andrew Gordon Wilson1 1 New York University 2 Samsung AI Center Moscow 3 Samsung-HSE Laboratory, National Research University Higher School of Economics Abstract We propose SWA-Gaussian (SWAG), a simple, scalable, and general purpose The Cons: It's not as easy to parallelize. ... "We're standardizing OpenAI's deep learning framework on PyTorch to increase our research productivity at scale on GPUs (and have just released a PyTorch version of Spinning Up in Deep RL)" Trained MLP with 2 hidden layers and a sine prior. In fact, the use of Bayesian techniques in deep learning can be traced back to the 1990s’, in seminal works by Radford Neal, David MacKay, and Dayan et al. Also pull requests are welcome. You could think of this as a prior. These gave us tools to reason about deep models’ confidence, and achieved state-of-the-art performance on many tasks. Many researchers use RayTune.It's a scalable hyperparameter tuning framework, specifically for deep learning. fast-SWA achieves record results in every setting considered. Pyro enables flexible and expressive deep probabilistic modeling, unifying the best of modern deep learning and Bayesian modeling. Bayesian methods are (mostly) all about performing posterior inference given data, which returns a probability distribution. Course Overview. Something like PyMC3 (theano) or Edward (tensorflow). School participants will learn methods and techniques that are crucial for understanding current research in machine learning. You can easily use it with any deep learning framework (2 lines of code below), and it provides most state-of-the-art algorithms, including HyperBand, Population-based Training, Bayesian Optimization, and BOHB. Pyro is a universal probabilistic programming language (PPL) written in Python and supported by PyTorch on the backend. BoTorch is built on PyTorch and … Hi all, Just discover PyTorch yesterday, the dynamic graph idea is simply amazing! At the Deep|Bayes summer school, we will discuss how Bayesian Methods can be combined with Deep Learning and lead to better results in machine learning applications. In PyTorch, weight decay is provided as a parameter to the optimizer (see for example the weight_decay parameter for SGD). Should I Use It: In most cases, yes! For example, Pyro (from Uber AI Labs) enables flexible and expressive deep probabilistic modeling, unifying the best of modern deep learning and Bayesian modeling. I was experimenting with the approach described in “Randomized Prior Functions for Deep Reinforcement Learning” by Ian Osband et al. It offers principled uncertainty estimates from deep learning architectures. Bayesian deep learning is a field at the intersection between deep learning and Bayesian probability theory. Performance of fast-SWA on semi-supervised learning with CIFAR-10. Strong knowledge of machine learning and familiarity with deep learning. The notebooks are there to help you understand the material and teach you details of the PyTorch framework, including PyTorch Lightning. 1,763 - Mark the official implementation from paper authors ... Bayesian optimization provides sample-efficient global optimization for a broad range of applications, including automatic machine learning, engineering, physics, and experimental design. 18 Sep 2017 • thu-ml/zhusuan • In this paper we introduce ZhuSuan, a python probabilistic programming library for Bayesian deep learning, which conjoins the complimentary advantages of Bayesian methods and deep learning. I am wondering if anybody is (or plans to) developing a Bayesian Computation package in PyTorch? This post addresses three questions: The results demonstrate that with the support of high-resolution data, the uncertainty of MCFD simulations can be significantly reduced. This post is the first post in an eight-post series of Bayesian Convolutional Networks. SWAG, an extension of SWA, can approximate Bayesian model averaging in Bayesian deep learning and achieves state-of-the-art uncertainty calibration results in various settings. Install SWA was shown to improve performance in language modeling (e.g., AWD-LSTM on WikiText-2 [4]) and policy-gradient methods in deep reinforcement learning [3].
