Poly-View Contrastive Learning

no code implementations8 Mar 2024 Amitis Shidani, Devon Hjelm, Jason Ramapuram, Russ Webb, Eeshan Gunesh Dhekane, Dan Busbridge

Contrastive learning typically matches pairs of related views among a number of unrelated negative views.

Do Self-Supervised and Supervised Methods Learn Similar Visual Representations?

no code implementations1 Oct 2021 Tom George Grigg, Dan Busbridge, Jason Ramapuram, Russ Webb

Despite the success of a number of recent techniques for visual self-supervised deep learning, there has been limited investigation into the representations that are ultimately learned.

Stochastic Contrastive Learning

no code implementations1 Oct 2021 Jason Ramapuram, Dan Busbridge, Xavier Suau, Russ Webb

While state-of-the-art contrastive Self-Supervised Learning (SSL) models produce results competitive with their supervised counterparts, they lack the ability to infer latent variables.

Evaluating the fairness of fine-tuning strategies in self-supervised learning

no code implementations1 Oct 2021 Jason Ramapuram, Dan Busbridge, Russ Webb

In this work we examine how fine-tuning impacts the fairness of contrastive Self-Supervised Learning (SSL) models.

Hypersim: A Photorealistic Synthetic Dataset for Holistic Indoor Scene Understanding

2 code implementations ICCV 2021 Mike Roberts, Jason Ramapuram, Anurag Ranjan, Atulit Kumar, Miguel Angel Bautista, Nathan Paczan, Russ Webb, Joshua M. Susskind

To create our dataset, we leverage a large repository of synthetic scenes created by professional artists, and we generate 77, 400 images of 461 indoor scenes with detailed per-pixel labels and corresponding ground truth geometry.

Improving Discrete Latent Representations With Differentiable Approximation Bridges

no code implementations9 May 2019 Jason Ramapuram, Russ Webb

Modern neural network training relies on piece-wise (sub-)differentiable functions in order to use backpropagation to update model parameters.

Mirroring to Build Trust in Digital Assistants

no code implementations2 Apr 2019 Katherine Metcalf, Barry-John Theobald, Garrett Weinberg, Robert Lee, Ing-Marie Jonsson, Russ Webb, Nicholas Apostoloff

We describe experiments towards building a conversational digital assistant that considers the preferred conversational style of the user.

Variational Saccading: Efficient Inference for Large Resolution Images

1 code implementation8 Dec 2018 Jason Ramapuram, Maurits Diephuis, Frantzeska Lavda, Russ Webb, Alexandros Kalousis

Image classification with deep neural networks is typically restricted to images of small dimensionality such as 224 x 244 in Resnet models [24].
