Machine Learning

• Simple Unsupervised Phoneme Segmentation from Self-Supervised Pretrained Models [code]
  - Unoffical implementation of INTERSPEECH 2021 paper
  - Directly determines phoneme boundaries w/o additional training from self-supervised representations using dynamic programming.

• NoteKing: Automatic Lecture Notes
  2021 Cinnamon AI Bootcamp MVP
  - Created and deployed a tool to automatically transcribe pictures of blackboard lectures into lecture notes using deep learning models for text detection and OCR.
  - Won 2nd place award at 2021 Cinnamon AI Bootcamp.

• Non-Contact Voltage Measurement
  Industrial Colab Research Project
  - Deployed a system to measure voltage signals without electrical contact in real-time, using sensors and on-device neural networks.
  - Generated synthesized training data for machine learning models to convert measured signal back to expected voltage.

Others

• 夢想家園: Interactive Interior Decoration using Indoors Positioning [code]
  Embedded Systems Lab Group Final Project
  - Built an interactive interior design system that lets users place objects in a virtual 3D model, corresponding to their real-world location.
  - Deployed our integrated system with a STM32 microcontroller, 4 Raspberry Pis, and host computer through Bluetooth Low Energy and Wi-Fi.

• Iterative Turbo Code Decoder [code]
  Integrated Circuit Design Lab Group Final Project
  - Designed a turbo code decoder in Verilog from scratch, completing all steps of digital IC design flow (system design, RTL, synthesis & gate level simulation, APR etc.)
  - Lowered bit error rates by a factor of 100 at SNR range of 0 to 5 dB.
