Research Experience

Cross-View Visual Place Recognition with AlphaEarth

National University of Singapore, Tongji University
Oct 2025 – Present

  • Developing a cross-view visual place recognition framework that leverages DeepMind’s AlphaEarth, a global 10m-resolution multimodal satellite embedding model.
  • Designing a decoder network to perform place recognition directly in the AlphaEarth feature space, enabling robust location retrieval under large viewpoint and appearance changes.
  • Building an alignment encoder that maps ground-level optical images into the AlphaEarth latent space, supporting cross-view matching between ground imagery and satellite representations.
  • Investigating the spatial consistency and discriminability of AlphaEarth embeddings, and exploring whether geographic coordinates can be regressed from satellite feature vectors.
  • Evaluating model robustness across diverse regions and viewpoints, providing insights for global-scale geo-localization and multi-view mapping applications.

Multi-Objective Optimization of GFlowNet

Tongji University
Feb 2025 – Dec 2025

  • Extended the original GFlowNet framework from single-objective to multi-objective optimization, integrating reward, cost, and diversity objectives
  • Designed a new objective formulation with additional evaluation metrics, applying concepts from evolutionary game theory to model trade-offs and dynamic policy updates
  • Implemented and validated the extended model on molecular datasets, demonstrating improved sample cost and reward performance over the baseline

Multi-Agent Spatio-temporal Coordination (Research Assistant)

Tongji University
Feb 2025 – Dec 2025

  • Conducted research on multi-agent spatiotemporal coordination in embodied intelligence, with focus on collaborative perception, task planning, and motion synchronization
  • Explored strategies for communication and policy learning among agents to enable robust cooperation for perception and prediction
  • Enhanced the generalization capability of embodied agents across diverse domestic scenarios (e.g., autonomous driving)

Projects

Here are some projects that I have worked on over the years.

BiLSTM-CRF Chinese Word Segmentation System
Chinese Word Segmentation

BiLSTM-CRF Chinese Word Segmentation System

This project implements a Chinese Word Segmentation (CWS) system based on a BiLSTM-CRF architecture, enhanced with several advanced features such as pretrained character embeddings, character-type embeddings, bigram embeddings, multi-corpus training, a customized CRF decoder with illegal transition constraints, loss visualization, and evaluation utilities. The system supports common CWS datasets including MSRA, PKU, and Souhu, and provides a complete workflow from data preprocessing → vocabulary construction → model training → evaluation → inference. Experiments show that the model achieves an F1 score of approximately 0.91 on the MSRA benchmark. The project is modular, extendable, and suitable for both engineering use and academic exploration.
