6.300: Signal Processing

Feb 2025 - May 2025: Depression/non-depression classification from facial expression videos collected in an at-home virtual therapy-like setting.

• Optimize Mixed Effects Random Forest (MERF) models for depression/non-depression classification.

• Research and develop text topic clustering algorithms for speech collected during personal reflection.

Feb 2024 - May 2024: Depression/non-depression classification from facial expression videos collected in an at-home virtual therapy-like setting.

• Develop a data processing and machine learning pipelines for the classification task.

• Explore different facial expression features, model architectures, model hyperparameters based on relevant literature.

• Final model reached ~65% accuracy.

Jun 2022 - Dec 2022: Development experiments for an augmented VR headset with sensors for physiological signals.

• Cognitive load experiment: trouble-shoot Unity Tetris game, improve brain signal processing and data plotting pipeline with Python, run in-person study with 30+ participants

• Visual Evoked Potential (VEP) experiment: research literature on current standards for VEP recording, test different experimental procedures.

Intern Project: An audit log for an internal CLI for Pulumi Cloud SaaS. This tool automatically logs the details of manual edits made to the production database via the CLI interface without interrupting the engineers' workflow. Designed and implemented end-to-end using Go, Cobra, REST APIs, and MySQL.
