VC Theory for Inventory Policies

no code implementations17 Apr 2024 Yaqi Xie, Will Ma, Linwei Xin

Second, the number of parameters in a policy class may not be the correct measure of overfitting error: in fact, the class of policies defined by T time-varying base-stock levels exhibits a generalization error comparable to that of the two-parameter (s, S) policy class.

MUGC: Machine Generated versus User Generated Content Detection

no code implementations28 Mar 2024 Yaqi Xie, Anjali Rawal, Yujing Cen, Dixuan Zhao, Sunil K Narang, Shanu Sushmita

As advanced modern systems like deep neural networks (DNNs) and generative AI continue to enhance their capabilities in producing convincing and realistic content, the need to distinguish between user-generated and machine generated content is becoming increasingly evident.

Negative Yields Positive: Unified Dual-Path Adapter for Vision-Language Models

1 code implementation19 Mar 2024 Ce Zhang, Simon Stepputtis, Katia Sycara, Yaqi Xie

Recently, large-scale pre-trained Vision-Language Models (VLMs) have demonstrated great potential in learning open-world visual representations, and exhibit remarkable performance across a wide range of downstream tasks through efficient fine-tuning.

Toward General-Purpose Robots via Foundation Models: A Survey and Meta-Analysis

no code implementations14 Dec 2023 Yafei Hu, Quanting Xie, Vidhi Jain, Jonathan Francis, Jay Patrikar, Nikhil Keetha, Seungchan Kim, Yaqi Xie, Tianyi Zhang, Shibo Zhao, Yu Quan Chong, Chen Wang, Katia Sycara, Matthew Johnson-Roberson, Dhruv Batra, Xiaolong Wang, Sebastian Scherer, Zsolt Kira, Fei Xia, Yonatan Bisk

Motivated by the impressive open-set performance and content generation capabilities of web-scale, large-capacity pre-trained models (i. e., foundation models) in research fields such as Natural Language Processing (NLP) and Computer Vision (CV), we devote this survey to exploring (i) how these existing foundation models from NLP and CV can be applied to the field of robotics, and also exploring (ii) what a robotics-specific foundation model would look like.

Translating Natural Language to Planning Goals with Large-Language Models

1 code implementation10 Feb 2023 Yaqi Xie, Chen Yu, Tongyao Zhu, Jinbin Bai, Ze Gong, Harold Soh

Recent large language models (LLMs) have demonstrated remarkable performance on a variety of natural language processing (NLP) tasks, leading to intense excitement about their applicability across various domains.

Embedding Symbolic Temporal Knowledge into Deep Sequential Models

no code implementations28 Jan 2021 Yaqi Xie, Fan Zhou, Harold Soh

However, when data is limited, simpler models such as logic/rule-based methods work surprisingly well, especially when relevant prior knowledge is applied in their construction.

Robot Capability and Intention in Trust-based Decisions across Tasks

no code implementations3 Sep 2019 Yaqi Xie, Indu P Bodala, Desmond C. Ong, David Hsu, Harold Soh

In this paper, we present results from a human-subject study designed to explore two facets of human mental models of robots---inferred capability and intention---and their relationship to overall trust and eventual decisions.
