Calibrating Long-form Generations from Large Language Models

no code implementations9 Feb 2024 Yukun Huang, Yixin Liu, Raghuveer Thirukovalluru, Arman Cohan, Bhuwan Dhingra

Addressing this gap, we introduce a unified calibration framework, in which both the correctness of the LLMs' responses and their associated confidence levels are treated as distributions across a range of scores.

Pragmatic Evaluation of Clarifying Questions with Fact-Level Masking

no code implementations17 Oct 2023 Matthew Toles, Yukun Huang, Zhou Yu, Luis Gravano

Here we present a definition and framework for natural language pragmatic asking of clarifying questions (PACQ), the problem of generating questions that result in answers useful for a reasoning task.

DreamTime: An Improved Optimization Strategy for Text-to-3D Content Creation

no code implementations21 Jun 2023 Yukun Huang, Jianan Wang, Yukai Shi, Xianbiao Qi, Zheng-Jun Zha, Lei Zhang

Text-to-image diffusion models pre-trained on billions of image-text pairs have recently enabled text-to-3D content creation by optimizing a randomly initialized Neural Radiance Fields (NeRF) with score distillation.

Generalized UAV Object Detection via Frequency Domain Disentanglement

no code implementations CVPR 2023 Kunyu Wang, Xueyang Fu, Yukun Huang, Chengzhi Cao, Gege Shi, Zheng-Jun Zha

This loss enables the network to concentrate on extracting domain-invariant spectrum and domain-specific spectrum, so as to achieve better disentangling results.

In-context Learning Distillation: Transferring Few-shot Learning Ability of Pre-trained Language Models

no code implementations20 Dec 2022 Yukun Huang, Yanda Chen, Zhou Yu, Kathleen McKeown

We propose to combine in-context learning objectives with language modeling objectives to distill both the ability to read in-context examples and task knowledge to the smaller models.

Neural Dependencies Emerging from Learning Massive Categories

no code implementations CVPR 2023 Ruili Feng, Kecheng Zheng, Kai Zhu, Yujun Shen, Jian Zhao, Yukun Huang, Deli Zhao, Jingren Zhou, Michael Jordan, Zheng-Jun Zha

Through investigating the properties of the problem solution, we confirm that neural dependency is guaranteed by a redundant logit covariance matrix, which condition is easily met given massive categories, and that neural dependency is highly sparse, implying that one category correlates to only a few others.

Rank Diminishing in Deep Neural Networks

no code implementations13 Jun 2022 Ruili Feng, Kecheng Zheng, Yukun Huang, Deli Zhao, Michael Jordan, Zheng-Jun Zha

By virtue of our numerical tools, we provide the first empirical analysis of the per-layer behavior of network rank in practical settings, i. e., ResNets, deep MLPs, and Transformers on ImageNet.

Learning a Better Initialization for Soft Prompts via Meta-Learning

no code implementations25 May 2022 Yukun Huang, Kun Qian, Zhou Yu

So pre-trained prompt tuning (PPT) is proposed to initialize prompts by leveraging pre-training data.

ICDM 2020 Knowledge Graph Contest: Consumer Event-Cause Extraction

no code implementations28 Oct 2021 Congqing He, Jie Zhang, Xiangyu Zhu, Huan Liu, Yukun Huang

To this end, we introduce a fresh perspective to revisit the relational event-cause extraction task and propose a novel sequence tagging framework, instead of extracting event types and events-causes separately.

Attack-Guided Perceptual Data Generation for Real-World Re-Identification

no code implementations ICCV 2021 Yukun Huang, Xueyang Fu, Zheng-Jun Zha

In unconstrained real-world surveillance scenarios, person re-identification (Re-ID) models usually suffer from different low-level perceptual variations, e. g., cross-resolution and insufficient lighting.

Real-world Person Re-Identification via Degradation Invariance Learning

no code implementations CVPR 2020 Yukun Huang, Zheng-Jun Zha, Xueyang Fu, Richang Hong, Liang Li

Person re-identification (Re-ID) in real-world scenarios usually suffers from various degradation factors, e. g., low-resolution, weak illumination, blurring and adverse weather.
