Stochastic neural net weights are used in a variety of contexts, including regularization, Bayesian neural nets, exploration in reinforcement learning, and evolution strategies. Unfortunately, due to the large number of weights, all the examples in a mini-batch typically share the same weight perturbation, thereby limiting the variance reduction effect of large mini-batches. We introduce flipout, an efficient method for decorrelating the gradients within a mini-batch by implicitly sampling…

Hyperparameter Ensembles for Robustness and Uncertainty Quantification

TLDR
This paper proposes hyper-deep ensembles, a simple procedure that involves a random search over different hyperparameters, themselves stratified across multiple random initializations, and proposes a parameter efficient version, hyper-batch ensembls, which builds on the layer structure of batch ensembleles and self-tuning networks.

An Empirical Study of Large-Batch Stochastic Gradient Descent with Structured Covariance Noise

TLDR
The empirical studies with standard deep learning model-architectures and datasets shows that the proposed add covariance noise to the gradients method not only improves generalization performance in large-batch training, but furthermore, does so in a way where the optimization performance remains desirable and the training duration is not elongated.

BatchEnsemble: An Alternative Approach to Efficient Ensemble and Lifelong Learning

TLDR
BatchEnsemble is proposed, an ensemble method whose computational and memory costs are significantly lower than typical ensembles and can easily scale up to lifelong learning on Split-ImageNet which involves 100 sequential learning tasks.

Efficient Low Rank Gaussian Variational Inference for Neural Networks

TLDR
It is found that adding low- rank terms to parametrized diagonal covariance does not improve predictive performance except on small networks, but low-rank terms added to a constant diagonal covariances improves performance on small and large-scale network architectures.

Deep Ensembles: A Loss Landscape Perspective

TLDR
Developing the concept of the diversity--accuracy plane, it is shown that the decorrelation power of random initializations is unmatched by popular subspace sampling methods and the experimental results validate the hypothesis that deep ensembles work well under dataset shift.

Learning Sparse Networks Using Targeted Dropout

TLDR
Target dropout is introduced, a method for training a neural network so that it is robust to subsequent pruning, and improves upon more complicated sparsifying regularisers while being simple to implement and easy to tune.

HWA: Hyperparameters Weight Averaging in Bayesian Neural Networks

TLDR
HWA (Hyperparameters Weight Averaging) algorithm is proposed that exploits an averaging procedure in order to optimize faster and achieve better accuracy and develops the main algorithm using the simple averaging heuristic.

AutoLRS: Automatic Learning-Rate Schedule by Bayesian Optimization on the Fly

TLDR
This paper proposes an efficient method, AutoLRS, which automatically optimizes the learning rate (LR) schedule for each training stage by modeling training dynamics, and demonstrates the advantages and the generality of this method through extensive experiments of training DNNs for tasks from diverse domains using different optimizers.

Flattening Sharpness for Dynamic Gradient Projection Memory Benefits Continual Learning

TLDR
A soft weight is introduced to represent the importance of each basis representing past tasks in GPM, which can be adaptively learned during the learning process, so that less important bases can be dynamically released to improve the sensitivity of new skill learning.

TLDR
A simple, low-level approach for embedding probabilistic programming in a deep learning ecosystem, which achieves an optimal linear speedup from 1 to 256 TPUv2 chips.

Variational Dropout and the Local Reparameterization Trick

TLDR
The Variational dropout method is proposed, a generalization of Gaussian dropout, but with a more flexibly parameterized posterior, often leading to better generalization in stochastic gradient variational Bayes.

Regularizing and Optimizing LSTM Language Models

TLDR
This paper proposes the weight-dropped LSTM which uses DropConnect on hidden-to-hidden weights as a form of recurrent regularization and introduces NT-ASGD, a variant of the averaged stochastic gradient method, wherein the averaging trigger is determined using a non-monotonic condition as opposed to being tuned by the user.

This work views the noisy gradient as a random variable, and form an inexpensive approximation of the generating procedure for the gradient sample, making it a useful control variate for variance reduction.

Bayesian Compression for Deep Learning

TLDR
This work argues that the most principled and effective way to attack the problem of compression and computational efficiency in deep learning is by adopting a Bayesian point of view, where through sparsity inducing priors the authors prune large parts of the network.

TLDR
