Multiscale Video Pretraining for Long-Term Activity Forecasting

no code implementations24 Jul 2023 Reuben Tan, Matthias De Lange, Michael Iuzzolino, Bryan A. Plummer, Kate Saenko, Karl Ridgeway, Lorenzo Torresani

To alleviate this issue, we propose Multiscale Video Pretraining (MVP), a novel self-supervised pretraining approach that learns robust representations for forecasting by learning to predict contextualized representations of future video clips over multiple timescales.

EgoAdapt: A multi-stream evaluation study of adaptation to real-world egocentric user video

1 code implementation11 Jul 2023 Matthias De Lange, Hamid Eghbalzadeh, Reuben Tan, Michael Iuzzolino, Franziska Meier, Karl Ridgeway

We introduce an evaluation framework that directly exploits the user's data stream with new metrics to measure the adaptation gain over the population model, online generalization, and hindsight performance.

How You Move Your Head Tells What You Do: Self-supervised Video Representation Learning with Egocentric Cameras and IMU Sensors

no code implementations4 Oct 2021 Satoshi Tsutsui, Ruta Desai, Karl Ridgeway

We are particularly interested in learning egocentric video representations benefiting from the head-motion generated by users' daily activities, which can be easily obtained from IMU sensors embedded in AR/VR devices.

Open-Ended Content-Style Recombination Via Leakage Filtering

no code implementations ICLR 2019 Karl Ridgeway, Michael C. Mozer

We present a domain-independent method that permits the open-ended recombination of style of one image with the content of another.

Adapted Deep Embeddings: A Synthesis of Methods for $k$-Shot Inductive Transfer Learning

2 code implementations22 May 2018 Tyler R. Scott, Karl Ridgeway, Michael C. Mozer

We hope our results will motivate a unification of research in weight transfer, deep metric learning, and few-shot learning.

Learning Deep Disentangled Embeddings with the F-Statistic Loss

3 code implementations NeurIPS 2018 Karl Ridgeway, Michael C. Mozer

Deep-embedding methods aim to discover representations of a domain that make explicit the domain's class structure and thereby support few-shot learning.

A Survey of Inductive Biases for Factorial Representation-Learning

no code implementations15 Dec 2016 Karl Ridgeway

Supervised inductive biases are constraints on the representations based on additional information connected to observations.

Learning to Generate Images with Perceptual Similarity Metrics

1 code implementation19 Nov 2015 Jake Snell, Karl Ridgeway, Renjie Liao, Brett D. Roads, Michael C. Mozer, Richard S. Zemel

We propose instead to use a loss function that is better calibrated to human perceptual judgments of image quality: the multiscale structural-similarity score (MS-SSIM).
