Improved Group Robustness via Classifier Retraining on Independent Splits

1 code implementation20 Apr 2022 Thien Hang Nguyen, Hongyang R. Zhang, Huy Le Nguyen

Given a limited amount of group labels at training time, Just Train Twice (Liu et al., 2021), or JTT in short, is a two-stage method that infers a pseudo group label for every unlabeled example first, then applies group DRO based on the inferred group labels.

Linear Constraints Learning for Spiking Neurons

no code implementations10 Mar 2021 Huy Le Nguyen, Dominique Chu

In the ubiquitous Iris and MNIST datasets, our algorithm achieves competitive predictive performance with state-of-the-art approaches.

Multi-view Audio and Music Classification

no code implementations3 Mar 2021 Huy Phan, Huy Le Nguyen, Oliver Y. Chén, Lam Pham, Philipp Koch, Ian McLoughlin, Alfred Mertins

The learned embedding in the subnetworks are then concatenated to form the multi-view embedding for classification similar to a simple concatenation network.

Constraints on Hebbian and STDP learned weights of a spiking neuron

no code implementations14 Dec 2020 Dominique Chu, Huy Le Nguyen

In the case of pure Hebbian learning, we find that the normalised weights equal the promotion probabilities of weights up to correction terms that depend on the learning rate and are usually small.

Self-Attention Generative Adversarial Network for Speech Enhancement

1 code implementation18 Oct 2020 Huy Phan, Huy Le Nguyen, Oliver Y. Chén, Philipp Koch, Ngoc Q. K. Duong, Ian McLoughlin, Alfred Mertins

Existing generative adversarial networks (GANs) for speech enhancement solely rely on the convolution operation, which may obscure temporal dependencies across the sequence input.
