Gated Recurrent Neural Networks with Weighted Time-Delay Feedback

no code implementations1 Dec 2022 N. Benjamin Erichson, Soon Hoe Lim, Michael W. Mahoney

We prove the existence and uniqueness of solutions for the continuous-time model, and we demonstrate that the proposed feedback mechanism can help improve the modeling of long-term dependencies.

Chaotic Regularization and Heavy-Tailed Limits for Deterministic Gradient Descent

1 code implementation23 May 2022 Soon Hoe Lim, Yijun Wan, Umut Şimşekli

Recent studies have shown that gradient descent (GD) can achieve improved generalization when its dynamics exhibits a chaotic behavior.

NoisyMix: Boosting Model Robustness to Common Corruptions

no code implementations2 Feb 2022 N. Benjamin Erichson, Soon Hoe Lim, Winnie Xu, Francisco Utrera, Ziang Cao, Michael W. Mahoney

For many real-world applications, obtaining stable and robust statistical performance is more important than simply achieving state-of-the-art predictive test accuracy, and thus robustness of neural networks is an increasingly important topic.

Noisy Feature Mixup

2 code implementations ICLR 2022 Soon Hoe Lim, N. Benjamin Erichson, Francisco Utrera, Winnie Xu, Michael W. Mahoney

We introduce Noisy Feature Mixup (NFM), an inexpensive yet effective method for data augmentation that combines the best of interpolation based training and noise injection schemes.

Noisy Recurrent Neural Networks

1 code implementation NeurIPS 2021 Soon Hoe Lim, N. Benjamin Erichson, Liam Hodgkinson, Michael W. Mahoney

We provide a general framework for studying recurrent neural networks (RNNs) trained by injecting noise into hidden states.

Understanding Recurrent Neural Networks Using Nonequilibrium Response Theory

no code implementations19 Jun 2020 Soon Hoe Lim

This representation is interpretable and disentangles the input signal from the SRNN architecture.

Predicting Critical Transitions in Multiscale Dynamical Systems Using Reservoir Computing

2 code implementations10 Aug 2019 Soon Hoe Lim, Ludovico Theo Giorgini, Woosok Moon, J. S. Wettlaufer

We study the problem of predicting rare critical transition events for a class of slow-fast nonlinear dynamical systems.
