Research Projects

AI4Data-LLM & Agents

Our studies starts with an Evolutionary Large Language Model (LLM) for generating initial feature transformations, then advances to an unsupervised, agentic approach using Generator-Critic LLM agents and Duet-Play Teaming for transformation and criticism, culminating in a unified Agentic Feature Augmentation process that integrates selection and generation through teaming, planning, and memories.

AI4Data-GenAI

We explore controllable generative AI systems for feature selection, generation, and transformation, leveraging techniques such as embedding space optimization, categorical hashing, autoregressive modeling, graph contrastive pre-training, and neuro-symbolic embedding. Together, they aim to build a unified paradigm for efficient, interpretable, and privacy-preserving feature engineering in machine learning.

AI4Data-RL

We explore feature selection and generation using reinforcement learning (RL), proposing methods like interactive RL with decision trees, multi-agent RL for subspace exploration, and diversity-aware RL to optimize feature subsets. These approaches automate and enhance feature selection by leveraging single or multi-agent strategies, hierarchical RL, and categorical hashing, improving model accuracy, scalability, and interpretability across high-dimensional datasets.

D4AI-Time Series

We advance deep time series learning by tackling two fundamental challenges: regularities and distribution shift. We introduce deep expansion learning to capture periodic structures in time series for more accurate long-term forecasting, propose general paradigms to mitigate distribution shifts to ensure models remain reliable and adaptive across diverse and changing environments, and develop conditional generative flows to address time series imputation.

D4AI-Geospatial

This project develops knowledge-guided geospatial representation learning by designing models that capture spatial substructures, temporal dependencies, and region-level correlations. It advances representation learning with innovations such as mutual information maximization, adversarial training, and reinforcement-driven imitation to improve profiling, prediction, and embedding in mobile and spatiotemporal networks. Together, these works form a unified approach that integrates peer interactions, temporal dynamics, and multi-view spatial structures for robust and interpretable geospatial intelligence.
