Masked Autoencoders As The Unified Learners For Pre-Trained Sentence Representation

no code implementations30 Jul 2022 Alexander Liu, Samuel Yang

As such, it calls for different pre-training methods for specific scenarios, and the pre-trained models are likely to be limited by their universality and representation quality.

Monarch: Expressive Structured Matrices for Efficient and Accurate Training

1 code implementation1 Apr 2022 Tri Dao, Beidi Chen, Nimit Sohoni, Arjun Desai, Michael Poli, Jessica Grogan, Alexander Liu, Aniruddh Rao, Atri Rudra, Christopher Ré

To address these issues, we propose a class of matrices (Monarch) that is hardware-efficient (they are parameterized as products of two block-diagonal matrices for better hardware utilization) and expressive (they can represent many commonly used transforms).

Routing with Self-Attention for Multimodal Capsule Networks

no code implementations1 Dec 2021 Kevin Duarte, Brian Chen, Nina Shvetsova, Andrew Rouditchenko, Samuel Thomas, Alexander Liu, David Harwath, James Glass, Hilde Kuehne, Mubarak Shah

We present a new multimodal capsule network that allows us to leverage the strength of capsules in the context of a multimodal learning framework on large amounts of video data.

Spoken Moments: Learning Joint Audio-Visual Representations from Video Descriptions

no code implementations CVPR 2021 Mathew Monfort, SouYoung Jin, Alexander Liu, David Harwath, Rogerio Feris, James Glass, Aude Oliva

With this in mind, the descriptions people generate for videos of different dynamic events can greatly improve our understanding of the key information of interest in each video.
