AmbigDocs: Reasoning across Documents on Different Entities under the Same Name

no code implementations18 Apr 2024 Yoonsang Lee, Xi Ye, Eunsol Choi

and a set of documents discussing different people named Michael Jordan, can LMs distinguish entity mentions to generate a cohesive answer to the question?

Stochastic approach for elliptic problems in perforated domains

no code implementations18 Mar 2024 Jihun Han, Yoonsang Lee

We propose a neural network-based mesh-free approach for perforated domain problems.

Crafting In-context Examples according to LMs' Parametric Knowledge

no code implementations16 Nov 2023 Yoonsang Lee, Pranav Atreya, Xi Ye, Eunsol Choi

We perform analysis on three multi-answer question answering datasets, which allows us to further study answer set ordering strategies based on the LM's knowledge of each answer.

Adaptive Tracking of a Single-Rigid-Body Character in Various Environments

no code implementations14 Aug 2023 Taesoo Kwon, Taehong Gu, Jaewon Ahn, Yoonsang Lee

Using the centroidal dynamics model (CDM) to express the full-body character as a single rigid body (SRB) and training a policy to track a reference motion, we can obtain a policy that is capable of adapting to various unobserved environmental changes and controller transitions without requiring any additional learning.

A Neural Network Approach for Homogenization of Multiscale Problems

no code implementations4 Jun 2022 Jihun Han, Yoonsang Lee

Compared with other network-based approaches for multiscale problems, the proposed method is free from the design of hand-crafted neural network architecture and the cell problem to calculate the homogenization coefficient.

Hierarchical Learning to Solve Partial Differential Equations Using Physics-Informed Neural Networks

no code implementations2 Dec 2021 Jihun Han, Yoonsang Lee

In this work, we propose a hierarchical approach to improve the convergence rate and accuracy of the neural network solution to partial differential equations.

Understanding the Stability of Deep Control Policies for Biped Locomotion

no code implementations30 Jul 2020 Hwangpil Park, Ri Yu, Yoonsang Lee, Kyungho Lee, Jehee Lee

The goal of this study is to answer these questions by evaluating the push-recovery stability of deep policies compared to human subjects and a previous feedback controller.
