Random Field Augmentations for Self-Supervised Representation Learning

no code implementations7 Nov 2023 Philip Andrew Mansfield, Arash Afkanpour, Warren Richard Morningstar, Karan Singhal

In this work, we propose a new family of local transformations based on Gaussian random fields to generate image augmentations for self-supervised representation learning.

Towards Federated Learning Under Resource Constraints via Layer-wise Training and Depth Dropout

no code implementations11 Sep 2023 Pengfei Guo, Warren Richard Morningstar, Raviteja Vemulapalli, Karan Singhal, Vishal M. Patel, Philip Andrew Mansfield

To mitigate this issue and facilitate training of large models on edge devices, we introduce a simple yet effective strategy, Federated Layer-wise Learning, to simultaneously reduce per-client memory, computation, and communication costs.

Federated Training of Dual Encoding Models on Small Non-IID Client Datasets

no code implementations30 Sep 2022 Raviteja Vemulapalli, Warren Richard Morningstar, Philip Andrew Mansfield, Hubert Eichner, Karan Singhal, Arash Afkanpour, Bradley Green

In this work, we focus on federated training of dual encoding models on decentralized data composed of many small, non-IID (independent and identically distributed) client datasets.

Camera View Adjustment Prediction for Improving Image Composition

no code implementations15 Apr 2021 Yu-Chuan Su, Raviteja Vemulapalli, Ben Weiss, Chun-Te Chu, Philip Andrew Mansfield, Lior Shapira, Colvin Pitts

To address this issue, we propose a deep learning-based approach that provides suggestions to the photographer on how to adjust the camera view before capturing.

Contrastive Learning for Label Efficient Semantic Segmentation

no code implementations ICCV 2021 Xiangyun Zhao, Raviteja Vemulapalli, Philip Andrew Mansfield, Boqing Gong, Bradley Green, Lior Shapira, Ying Wu

While recent Convolutional Neural Network (CNN) based semantic segmentation approaches have achieved impressive results by using large amounts of labeled training data, their performance drops significantly as the amount of labeled data decreases.
