OccamVTS: Distilling Vision Models to 1% Parameters for Time Series Forecasting
OccamVTS: Distilling Vision Models to 1% Parameters for Time Series Forecasting Pinned

Sisuo Lyu, Siru Zhong, Weilin Ruan, Qingxiang Liu, Qingsong Wen, Hui Xiong, Yuxuan Liang

AAAI. 2026

We propose OccamVTS, a novel framework that distills large vision models to only 1% of their original parameters for efficient time series forecasting, demonstrating that extreme parameter reduction can be achieved while maintaining strong predictive performance through innovative distillation techniques.

Retrieval Augmented Spatio-Temporal Framework for Traffic Prediction
Retrieval Augmented Spatio-Temporal Framework for Traffic Prediction Pinned

Weilin Ruan, Xilin Dang, Ziyu Zhou, Sisuo Lyu, Yuxuan Liang

AAAI. 2026

We propose RAST, a universal framework that integrates retrieval-augmented mechanisms with spatio-temporal modeling to address limited contextual capacity and low predictability in traffic prediction. Our framework consists of three key designs: Decoupled Encoder and Query Generator, Spatio-temporal Retrieval Store and Retrievers, and Universal Backbone Predictor that flexibly accommodates pre-trained STGNNs or simple MLP predictors.

Cross Space and Time: A Spatio-Temporal Unitized Model for Traffic Flow Forecasting
Cross Space and Time: A Spatio-Temporal Unitized Model for Traffic Flow Forecasting Pinned

Weilin Ruan, Wenzhuo Wang, Siru Zhong, Wei Chen, Li Liu, Yuxuan Liang

TITS. 2025

This paper proposes a novel spatio-temporal unitized model for traffic flow forecasting that effectively captures complex dependencies across both space and time dimensions, achieving state-of-the-art performance on multiple benchmark datasets.

Towards Multi-Scenario Forecasting of Building Electricity Loads with Multimodal Data
Towards Multi-Scenario Forecasting of Building Electricity Loads with Multimodal Data Pinned

Yongzheng Liu, Siru Zhong, Gefeng Luo, Weilin Ruan, Yuxuan Liang

ACM MM. 2025

We propose MMLoad, a novel diffusion-based multimodal framework for multi-scenario building load forecasting with three innovations: Multimodal Data Enhancement Pipeline, Cross-modal Relation Encoder, and Scenario-Conditioned Diffusion Generator with uncertainty quantification, establishing a new paradigm for multimodal learning in smart energy systems.

Low-rank Adaptation for Spatio-Temporal Forecasting
Low-rank Adaptation for Spatio-Temporal Forecasting Pinned

Weilin Ruan, Wei Chen, Xilin Dang, Jianxiang Zhou, Weichuang Li, Xu Liu, Yuxuan Liang

ECML. 2025

This paper presents ST-LoRA, a novel low-rank adaptation framework as an off-the-shelf plugin for existing spatial-temporal prediction models, which alleviates node heterogeneity problems through node-level adjustments while minimally increasing parameters and training time.
