Regularized Parameter Uncertainty for Improving Generalization in Reinforcement Learning

CVPR 2024poster

In order for reinforcement learning (RL) agents to be deployed in real-world environments they must be able to generalize to unseen environments. However RL struggles with out-of-distribution generalization often due to over-fitting the particulars of the training environment. Although regularizatio…

Optimizing The Consumption Of Spiking Neural Networks With Activity Regularization

ICASSP 2022accepted

Reducing energy consumption is a critical point for neural network models running on edge devices. In this regard, reducing the number of multiply-accumulate (MAC) operations of Deep Neural Networks (DNNs) running on edge hardware accelerators will reduce the energy consumption during inference. Spi…

T-NGA: Temporal Network Grafting Algorithm for Learning to Process Spiking Audio Sensor Events

ICASSP 2022accepted

Spiking silicon cochlea sensors encode sound as an asynchronous stream of spikes from different frequency channels. The lack of labeled training datasets for spiking cochleas makes it difficult to train deep neural networks on the outputs of these sensors. This work proposes a self-supervised method…

Phased LSTM: Accelerating Recurrent Network Training for Long or Event-based Sequences

NeurIPS 2016oral

Recurrent Neural Networks (RNNs) have become the state-of-the-art choice for extracting patterns from temporal sequences. Current RNN models are ill suited to process irregularly sampled data triggered by events generated in continuous time by sensors or other neurons. Such data can occur, for examp…
