Hopformer: Homogeneity-Pursuit Transformer for Time Series Forecasting

Wan Zhang, Qinjie Lin, Chan Lee +3

Forecasting multiple time-series with high-dimensional covariates presents a core challenge: unifying common temporal patterns while retaining meaningful series-specific informatio…

PhyPrompt: RL-based Prompt Refinement for Physically Plausible Text-to-Video Generation

Shang Wu, Chenwei Xu, Zhuofan Xia +6

State-of-the-art text-to-video (T2V) generators frequently violate physical laws despite high visual quality. We show this stems from insufficient physical constraints in prompts r…

Towards Sparse Video Understanding and Reasoning

Chenwei Xu, Zhen Ye, Shang Wu +8

We present \revise (\underline{Re}asoning with \underline{Vi}deo \underline{S}parsity), a multi-round agent for video question answering (VQA). Instead of uniformly sampling frames…

StarEmbed: Benchmarking Time Series Foundation Models on Astronomical Observations of Variable Stars

Weijian Li, Hong-Yu Chen, Nabeel Rehemtulla +6

Current time series foundation model (TSFM) training corpora largely omit data with certain complexities like irregular temporal sampling. Astronomical time series of stellar fluxe…

Adaptive Batch Size Schedules for Distributed Training of Language Models with Data and Model Parallelism

Tim Tsz-Kit Lau, Weijian Li, Chenwei Xu +2

An appropriate choice of batch sizes in large-scale model training is crucial, yet it involves an intrinsic yet inevitable dilemma: large-batch training improves training efficienc…

Communication-Efficient Adaptive Batch Size Strategies for Distributed Local Gradient Methods

Tim Tsz-Kit Lau, Weijian Li, Chenwei Xu +2

Modern deep neural networks often require distributed training with many workers due to their large size. As the number of workers increases, communication overheads become the mai…

Incorporating Gradients to Rules: Towards Lightweight, Adaptive Provenance-based Intrusion Detection

Lingzhi Wang, Xiangmin Shen, Weijian Li +4

As cyber attacks grow increasingly sophisticated and stealthy, it becomes more imperative and challenging to detect intrusion from normal behaviors. Through fine-grained causality…

BiSHop: Bi-Directional Cellular Learning for Tabular Data with Generalized Sparse Modern Hopfield Model

Chenwei Xu, Yu-Chao Huang, Jerry Yao-Chieh Hu +4

We introduce the \textbf{B}i-Directional \textbf{S}parse \textbf{Hop}field Network (\textbf{BiSHop}), a novel end-to-end framework for deep tabular learning. BiSHop handles the two…

STanHop: Sparse Tandem Hopfield Model for Memory-Enhanced Time Series Prediction

Dennis Wu, Jerry Yao-Chieh Hu, Weijian Li +2

We present STanHop-Net (Sparse Tandem Hopfield Network) for multivariate time series prediction with memory-enhanced capabilities. At the heart of our approach is STanHop, a novel…
