- End-to-end trajectory forecasting project on the Argoverse 2 Motion Forecasting dataset.
- Implemented a forecasting pipeline that predicts future vehicle and pedestrian trajectories from past motion histories.
- Built data processing, model training, evaluation, and visualization workflows.
- Compared multiple forecasting approaches under a consistent experimental setup.
- Compared Linear, LSTM, Transformer, Direct Diffusion, and PCA Latent Diffusion models.
- Evaluated models with common trajectory forecasting metrics and visual analysis.
- Focused on reproducible end-to-end implementation rather than leaderboard-only tuning.

- WiFi CSI-based patient monitoring MVP for bed-state classification, fall-risk event detection, and respiration monitoring.
- Designed a camera-free monitoring system that uses wireless channel changes around a hospital bed to detect patient state and risk events.
- Built the MVP pipeline for CSI window features, model comparison, and monitoring-oriented classification.
- Organized the system around practical privacy-preserving patient monitoring scenarios.
- Classified bed-related states such as lying, standing, moving, leaving bed, and fall-like risk events.
- Used WiFi CSI signals as a privacy-preserving alternative to camera-based monitoring.
- Explored lightweight deep learning models for practical monitoring scenarios.
