Telling Left from Right: Identifying Geometry-Aware Semantic Correspondence

1 code implementation28 Nov 2023 Junyi Zhang, Charles Herrmann, Junhwa Hur, Eric Chen, Varun Jampani, Deqing Sun, Ming-Hsuan Yang

This paper identifies the importance of being geometry-aware for semantic correspondence and reveals a limitation of the features of current foundation models under simple post-processing.

Neuro-Inspired Fragmentation and Recall to Overcome Catastrophic Forgetting in Curiosity

1 code implementation26 Oct 2023 Jaedong Hwang, Zhang-Wei Hong, Eric Chen, Akhilan Boopathy, Pulkit Agrawal, Ila Fiete

Deep reinforcement learning methods exhibit impressive performance on a range of tasks but still struggle on hard exploration tasks in large environments with sparse rewards.

Grid Cell-Inspired Fragmentation and Recall for Efficient Map Building

1 code implementation11 Jul 2023 Jaedong Hwang, Zhang-Wei Hong, Eric Chen, Akhilan Boopathy, Pulkit Agrawal, Ila Fiete

Agents build and use a local map to predict their observations; high surprisal leads to a "fragmentation event" that truncates the local map.

Redeeming Intrinsic Rewards via Constrained Optimization

1 code implementation14 Nov 2022 Eric Chen, Zhang-Wei Hong, Joni Pajarinen, Pulkit Agrawal

However, on easy exploration tasks, the agent gets distracted by intrinsic rewards and performs unnecessary exploration even when sufficient task (also called extrinsic) reward is available.

Montezuma's Revenge Reinforcement Learning (RL)

Using machine learning on new feature sets extracted from 3D models of broken animal bones to classify fragments according to break agent

1 code implementation20 May 2022 Katrina Yezzi-Woodley, Alexander Terwilliger, Jiafeng Li, Eric Chen, Martha Tappen, Jeff Calder, Peter J. Olver

Distinguishing agents of bone modification at paleoanthropological sites is at the root of much of the research directed at understanding early hominin exploitation of large animal resources and the effects those subsistence behaviors had on early hominin evolution.

GapPredict: A Language Model for Resolving Gaps in Draft Genome Assemblies

1 code implementation21 May 2021 Eric Chen, Justin Chu, Jessica Zhang, Rene L. Warren, Inanc Birol

Short-read DNA sequencing instruments can yield over 1e+12 bases per run, typically composed of reads 150 bases long.

Small curvature concentration and Ricci flow smoothing

no code implementations25 Feb 2021 Pak-Yeung Chan, Eric Chen, Man-Chun Lee

We show that a complete Ricci flow of bounded curvature which begins from a manifold with a Ricci lower bound, local entropy bound, and small local scale-invariant integral curvature control will have global point-wise curvature control at positive times.

The Yamabe flow on asymptotically flat manifolds

no code implementations15 Feb 2021 Eric Chen, Yi Wang

We study the Yamabe flow starting from an asymptotically flat manifold $(M^n, g_0)$.

A Large Scale Speech Sentiment Corpus

no code implementations LREC 2020 Eric Chen, Zhiyun Lu, Hao Xu, Liangliang Cao, Yu Zhang, James Fan

We present a multimodal corpus for sentiment analysis based on the existing Switchboard-1 Telephone Speech Corpus released by the Linguistic Data Consortium.
