Grounded summary in plain prose; [AI Synthesis] only on inferred sentences.

Key points

Self-wiki (2026-05): An AI-powered personal wiki and Socratic Mirror service, where AI acts as the "OS" and the generated content serves as a high-resolution context window for self-reflection. Can be extended to coaching and education domains.

Mental Health for Every Mind (2025-09): An AI-driven cognitive behavioral therapy (CBT) system designed to support mental well-being through structured, human-like interaction.

Tiny Scheme interpreter (2024-10): A minimal Python-based Scheme interpreter demonstrating the pipeline: parse → abstract syntax tree → evaluate → result. Example: (begin (define r 10) (* pi (* r r))) returns 314.1592653589793.

Factoid Question Answering (2023-04): Focuses on retrieving precise answers from questions using NLP techniques; recent progress documented in a dedicated slide deck.

Natural Legal Language Processing (2022-06): Explores processing unstructured legal texts—including judgments, pleadings, and scholarly articles—using NLP methods for structured analysis.

Japan in Culture (2021-08): A cultural analysis of Japan from a Hong Kong University perspective, presented as a standalone slide set.

AI in Language & Speech (2017–2020): Covers multiple NLP applications including:
Mapping customer needs to product specs using word embeddings and SVM/Convolutional Neural Networks.
Recurrent and Long Short-Term Memory (LSTM) networks for sequence modeling.
Hierarchical attention networks for complex sentence understanding.
Top-N ranking algorithms for word embeddings and sentence classification.
A system for automatic speech recognition (iSpeaking) supporting L2 learners in English and Chinese.

Text simplification (2017-05): A system that simplifies complex English text while preserving meaning, with a paper accepted at COLING 2016.

Privacy-preserving similar search (2015-11): Implements nearest neighbor search for biometric or object matching while preserving privacy, particularly relevant in face recognition.

Online learning (2014-10): Explores data-driven education trends, including student behavior, assessment, and course design, with insights from NIPS Workshop. Highlights the transformative impact of MOOCs (e.g., edX, Coursera) and associated challenges.

P2PSIP (2013-05): A peer-to-peer network using Session Initiation Protocol (SIP), organized via Distributed Hash Tables (DHTs), currently under IETF standardization.

Incremental 3D reconstruction (2013-04): Uses Bayesian learning to build 3D models by selecting key views and updating them incrementally with new images, suitable for large-scale or real-time applications.

Finding better experts (2013-04): Applies homophily and TwitterRank algorithm to identify influential users in micro-blogging platforms by measuring topical and structural similarity.
