MANGO: A Benchmark for Evaluating Mapping and Navigation Abilities of Large Language Models

1 code implementation29 Mar 2024 Peng Ding, Jiading Fang, Peng Li, Kangrui Wang, Xiaochen Zhou, Mo Yu, Jing Li, Matthew R. Walter, Hongyuan Mei

The task is question-answering: for each maze, a large language model reads the walkthrough and answers hundreds of mapping and navigation questions such as "How should you go to Attic from West of House?"

A Wolf in Sheep's Clothing: Generalized Nested Jailbreak Prompts can Fool Large Language Models Easily

1 code implementation14 Nov 2023 Peng Ding, Jun Kuang, Dan Ma, Xuezhi Cao, Yunsen Xian, Jiajun Chen, ShuJian Huang

Finally, we analyze the failure of LLMs defense from the perspective of prompt execution priority, and propose corresponding defense strategies.

Algebraic and Statistical Properties of the Ordinary Least Squares Interpolator

1 code implementation27 Sep 2023 Dennis Shen, Dogyoon Song, Peng Ding, Jasjeet S. Sekhon

Deep learning research has uncovered the phenomenon of benign overfitting for over-parameterized statistical models, which has drawn significant theoretical interest in recent years.

Causal inference in network experiments: regression-based analysis and design-based properties

no code implementations14 Sep 2023 Mengsi Gao, Peng Ding

Although we focus on regression-based point estimators and standard errors, our theory holds under the design-based framework, which assumes that the randomness comes solely from the design of network experiments and allows for arbitrary misspecification of the regression models.

Kernel-based off-policy estimation without overlap: Instance optimality beyond semiparametric efficiency

no code implementations16 Jan 2023 Wenlong Mou, Peng Ding, Martin J. Wainwright, Peter L. Bartlett

When it is violated, the classical semi-parametric efficiency bound can easily become infinite, so that the instance-optimal risk depends on the function class used to model the regression function.

Multi-Source Causal Inference Using Control Variates

no code implementations30 Mar 2021 Wenshuo Guo, Serena Wang, Peng Ding, Yixin Wang, Michael I. Jordan

Across simulations and two case studies with real data, we show that this control variate can significantly reduce the variance of the ATE estimate.

Conservative Wasserstein Training for Pose Estimation

no code implementations ICCV 2019 Xiaofeng Liu, Yang Zou, Tong Che, Peng Ding, Ping Jia, Jane You, Kumar B. V. K

We propose to incorporate inter-class correlations in a Wasserstein training framework by pre-defining ($i. e.,$ using arc length of a circle) or adaptively learning the ground metric.

Rerandomization and Regression Adjustment

no code implementations26 Jun 2019 Xinran Li, Peng Ding

R. A. Fisher suggested blocking on discrete covariates in the design stage or conducting analysis of covariance (ANCOVA) in the analysis stage.

YNUDLG at IJCNLP-2017 Task 5: A CNN-LSTM Model with Attention for Multi-choice Question Answering in Examinations

no code implementations IJCNLP 2017 Min Wang, Qingxun Liu, Peng Ding, Yongbin Li, Xiaobing Zhou

In this paper, we perform convolutional neural networks (CNN) to learn the joint representations of question-answer pairs first, then use the joint representations as the inputs of the long short-term memory (LSTM) with attention to learn the answer sequence of a question for labeling the matching quality of each answer.
