Making Harmful Behaviors Unlearnable for Large Language Models

no code implementations2 Nov 2023 Xin Zhou, Yi Lu, Ruotian Ma, Tao Gui, Qi Zhang, Xuanjing Huang

Specifically, we introduce ``security vectors'', a few new parameters that can be separated from the LLM, to ensure LLM's responses are consistent with the harmful behavior.

Improved Knowledge Distillation for Pre-trained Language Models via Knowledge Selection

no code implementations1 Feb 2023 Chenglong Wang, Yi Lu, Yongyu Mu, Yimin Hu, Tong Xiao, Jingbo Zhu

Knowledge distillation addresses the problem of transferring knowledge from a teacher model to a student model.

Joint RIS Calibration and Multi-User Positioning

no code implementations8 Dec 2022 Yi Lu, Hui Chen, Jukka Talvitie, Henk Wymeersch, Mikko Valkama

Reconfigurable intelligent surfaces (RISs) are expected to be a key component enabling the mobile network evolution towards a flexible and intelligent 6G wireless platform.

Nonparametric Decoding for Generative Retrieval

1 code implementation5 Oct 2022 Hyunji Lee, Jaeyoung Kim, Hoyeon Chang, Hanseok Oh, Sohee Yang, Vlad Karpukhin, Yi Lu, Minjoon Seo

The generative retrieval model depends solely on the information encoded in its model parameters without external memory, its information capacity is limited and fixed.

The Short-term Impact of Congestion Taxes on Ridesourcing Demand and Traffic Congestion: Evidence from Chicago

no code implementations5 Jul 2022 Yuan Liang, Bingjie Yu, Xiaojian Zhang, Yi Lu, Linchuan Yang

To this end, this study applies difference-in-differences (i. e., a regression-based causal inference approach) to empirically evaluate the effects of the congestion tax policy on ridesourcing demand and traffic congestion in Chicago.

C+1 Loss: Learn to Classify C Classes of Interest and the Background Class Differentially

no code implementations29 Sep 2021 Changhuai Chen, Xile Shen, Mengyu Ye, Yi Lu, Jun Che, ShiLiang Pu

We figure out that the background class should be treated differently from the classes of interest during training.

Joint Positioning and Tracking via NR Sidelink in 5G-Empowered Industrial IoT: Releasing the Potential of V2X Technology

no code implementations15 Jan 2021 Yi Lu, Mike Koivisto, Jukka Talvitie, Elizaveta Rastorgueva-Foi, Toni Levanen, Elena Simona Lohan, Mikko Valkama

The fifth generation (5G) mobile networks with enhanced connectivity and positioning capabilities play an increasingly important role in the development of automated vehicle-to-everything (V2X) and other advanced industrial Internet of Things (IoT) systems.

On the Transferability of Minimal Prediction Preserving Inputs in Question Answering

no code implementations NAACL 2021 Shayne Longpre, Yi Lu, Christopher DuBois

In the context of question answering, we investigate competing hypotheses for the existence of MPPIs, including poor posterior calibration of neural models, lack of pretraining, and "dataset bias" (where a model learns to attend to spurious, non-generalizable cues in the training data).

An Exploration of Data Augmentation and Sampling Techniques for Domain-Agnostic Question Answering

no code implementations WS 2019 Shayne Longpre, Yi Lu, Zhucheng Tu, Chris DuBois

To produce a domain-agnostic question answering model for the Machine Reading Question Answering (MRQA) 2019 Shared Task, we investigate the relative benefits of large pre-trained language models, various data sampling strategies, as well as query and context paraphrases generated by back-translation.

Residual Attention based Network for Hand Bone Age Assessment

no code implementations21 Dec 2018 Eric Wu, Bin Kong, Xin Wang, Junjie Bai, Yi Lu, Feng Gao, Shaoting Zhang, Kunlin Cao, Qi Song, Siwei Lyu, Youbing Yin

The hierarchical attention components of the residual attention subnet force our network to focus on the key components of the X-ray images and generate the final predictions as well as the associated visual supports, which is similar to the assessment procedure of clinicians.
