FixMatch: Simplifying Semi-Supervised Learning with Consistency and Confidence

NeurIPS 2020poster

Semi-supervised learning (SSL) provides an effective means of leveraging unlabeled data to improve a model’s performance. This domain has seen fast progress recently, at the cost of requiring more complex methods. In this paper we propose FixMatch, an algorithm that is a significant simplification o…

Top-k Training of GANs: Improving GAN Performance by Throwing Away Bad Samples

NeurIPS 2020poster

We introduce a simple (one line of code) modification to the Generative Adversarial Network (GAN) training algorithm that materially improves results with no increase in computational cost. When updating the generator parameters, we simply zero out the gradient contributions from the elements of the…

MixMatch: A Holistic Approach to Semi-Supervised Learning

NeurIPS 2019poster

Semi-supervised learning has proven to be a powerful paradigm for leveraging unlabeled data to mitigate the reliance on large labeled datasets. In this work, we unify the current dominant approaches for semi-supervised learning to produce a new algorithm, MixMatch, that guesses low-entropy labels fo…

Realistic Evaluation of Deep Semi-Supervised Learning Algorithms

NeurIPS 2018spotlight

Semi-supervised learning (SSL) provides a powerful framework for leveraging unlabeled data when labels are limited or expensive to obtain. SSL algorithms based on deep neural networks have recently proven successful on standard benchmark tasks. However, we argue that these benchmarks fail to address…
