Ternary Spike: Learning Ternary Spikes for Spiking Neural Networks

1 code implementation11 Dec 2023 Yufei Guo, Yuanpei Chen, Xiaode Liu, Weihang Peng, Yuhan Zhang, Xuhui Huang, Zhe Ma

To handle the problem, we propose a ternary spike neuron to transmit information.

Can Language Models Be Tricked by Language Illusions? Easier with Syntax, Harder with Semantics

1 code implementation2 Nov 2023 Yuhan Zhang, Edward Gibson, Forrest Davis

We found that probabilities represented by LMs were more likely to align with human judgments of being "tricked" by the NPI illusion which examines a structural dependency, compared to the comparative and the depth-charge illusions which require sophisticated semantic understanding.

Learn Single-horizon Disease Evolution for Predictive Generation of Post-therapeutic Neovascular Age-related Macular Degeneration

no code implementations12 Aug 2023 Yuhan Zhang, Kun Huang, Mingchao Li, Songtao Yuan, Qiang Chen

We propose a single-horizon disease evolution network (SHENet) to predictively generate post-therapeutic SD-OCT images by inputting pre-therapeutic SD-OCT images with neovascular age-related macular degeneration (nAMD).

ReactGenie: A Development Framework for Complex Multimodal Interactions Using Large Language Models

no code implementations16 Jun 2023 Jackie Junrui Yang, Yingtian Shi, Yuhan Zhang, Karina Li, Daniel Wan Rosli, Anisha Jain, Shuning Zhang, Tianshi Li, James A. Landay, Monica S. Lam

This paper targets complex interactions, where users can issue multimodal commands that translate into one of the possible exponential combinations of actions/function invocations.

Acoustic Scene Clustering Using Joint Optimization of Deep Embedding Learning and Clustering Iteration

no code implementations9 Jun 2023 Yanxiong Li, Mingle Liu, Wucheng Wang, Yuhan Zhang, Qianhua He

In this study, we propose a method for acoustic scene clustering that jointly optimizes the procedures of feature learning and clustering iteration.

Feedback Effect in User Interaction with Intelligent Assistants: Delayed Engagement, Adaption and Drop-out

no code implementations17 Mar 2023 Zidi Xiu, Kai-Chen Cheng, David Q. Sun, Jiannan Lu, Hadas Kotek, Yuhan Zhang, Paul McCarthy, Christopher Klein, Stephen Pulman, Jason D. Williams

Next, we expand the time horizon to examine behavior changes and show that as users discover the limitations of the IA's understanding and functional capabilities, they learn to adjust the scope and wording of their requests to increase the likelihood of receiving a helpful response from the IA.

Representing Affect Information in Word Embeddings

no code implementations21 Sep 2022 Yuhan Zhang, Wenqi Chen, Ruihan Zhang, Xiajie Zhang

A growing body of research in natural language processing (NLP) and natural language understanding (NLU) is investigating human-like knowledge learned or encoded in the word embeddings from large language models.

Dynamic Metric Learning: Towards a Scalable Metric Space to Accommodate Multiple Semantic Scales

1 code implementation CVPR 2021 Yifan Sun, Yuke Zhu, Yuhan Zhang, Pengkun Zheng, Xi Qiu, Chi Zhang, Yichen Wei

%We argue that such flexibility is also important for deep metric learning, because different visual concepts indeed correspond to different semantic scales.
