Recent areas of focus
- Embedding-based Retrieval
Current Project
Selected Past Projects
- Efficient hybrid search in Vector Database [link]
Proposed better architecture and algorithm for the hybrid search, which includes both structured and unstructured data retrieval, with better trade-offs among speed, accuracy and resources.
Working with Zhilin GAO and Supervised by Dr. Ken YIU

ROS MQTT bridge [link]
This project established bidirectional communication between the local host and the IoT device using MQTT bridges. For the IoT device we use, it is integrated with the ROS system and features a camera that can capture both point
cloud and image data. By enabling the algorithm, the device can process this data and publish it to the local ROS topic. This device can also transmit data over a network. Due to the unknown public IPs of both the IoT device
and the local host, as well as the large amount of data to be transferred and the unstable networking circumstances, we opted to to use the MQTT protocol to facilitate their long-range data transfer.
- Search Engine [report]
Implemented numerous retrieval models, including Boolean, Fuzzy Boolean and Vector Space retrieval models, as well as an advanced model that we proposed and achieves better scores in average precision, R-precision and several aspects
for the long query.
- We Home Seekers [link]
Developed Website for Refugees in Hong Kong and Human Right topics. We worked closely with students from University of Maryland and Kyoto University to seek better ways to convey the content. We hope more and more Hong Kong people
can realize this global issue, and if possible, act with us to serve for those refugees, the home seekers.
Supervised by Dr. Grace NGAI and Dr. Shuheng LIN
- Silicon Coppelia [code]
Implemented Affective Computing programs based on the fuzzy-sets Model proposed in Silicon Coppelia and the Formalization of the
Affective Process by Professor Hoorn, who later proposed its Quantum version together with Dr. Johnny HO.
Supervised by Professor HOORN, Johannes Ferdinand and Baier, Thomas (Software Developer in Netherlands)
- Mindfulness meditation: Our mind could really benefit from it? [study]
Is practicing meditation completely risk-free, notwithstanding many of us have benefited greatly from that. During my first year as an undergraduate, I conducted a comprehensive investigation into the potential side effects of
mindfulness meditation. It is recommended that practitioners engage in mindfulness meditation under proper guidance to mitigate the risk of negative side effects.
