🚀 Projects

[Research] Collaboration w/ ETRI (2025.01 – 2025.12)
Time-series forecasting for proactive mobile-device handover. Developing a domain-agnostic model robust to speed prediction under changing environments, cell-deployment-agnostic approaches invariant to feature permutation and resilient to missing features.
Time Series Forecasting Wireless Communications

[Research] Embedding Space of VLM (2025.03 – 2025.07)
Collaborated with Prof. Junhyuk Kim (CAU) on VLM for semantic segmentation. Proposed two novel losses (HNS, UAI) for fine-tuning CLIP and one metric (Unmix Rate) for evaluating CLIP Zero-shot semantic segmentation. Achieved State-of-the-Art on CLIP ZS3 task.
