Few-Max: Few-Shot Domain Adaptation for Unsupervised Contrastive Representation Learning

1 code implementation21 Jun 2022 Ali Lotfi Rezaabad, Sidharth Kumar, Sriram Vishwanath, Jonathan I. Tamir

Pretraining on a large source data set and fine-tuning on the target samples is prone to overfitting in the few-shot regime, where only a small number of target samples are available.

Hyperbolic Graph Embedding with Enhanced Semi-Implicit Variational Inference

1 code implementation31 Oct 2020 Ali Lotfi Rezaabad, Rahi Kalantari, Sriram Vishwanath, Mingyuan Zhou, Jonathan Tamir

We show that the existing semi-implicit variational inference objective provably reduces information in the observed graph.

Long Short-Term Memory Spiking Networks and Their Applications

1 code implementation9 Jul 2020 Ali Lotfi Rezaabad, Sriram Vishwanath

The developed architecture and method for backpropagation within LSTM-based SNNs enable them to learn long-term dependencies with comparable results to conventional LSTMs.
