Hi! I'm Kenneth, and I previously studied at the School of Electrical Engineering, Nanyang Technological University, Singapore. My current research focuses on developing artificial intelligence techniques for soundscape augmentation, but I dabble in other projects related to soundscapes and acoustics here and there.
This page lists down a selection of publications that I have led or have been involved in, accompanied with publicly-accessible, paywall-free links to resources related to those publications. Publications are listed in reverse chronological order of publication/presentation date under their respective section headings. In addition to my publications, I have also included some code snippets and resources that I have created/used myself over the course of teaching content related to university-level courses.
Generally, links to the different resources are classified under the following types:
- [[manuscript]]: Full-texts of the publication uploaded to arXiv, the NTU Digital Repository, or other publicly-available locations.
- [[overleaf]]: Source TeX and PDF files of supplementary material I created/used for teaching of university-level course content, hosted on Overleaf.
- [[code]]: Code repositories or replication code for the publication uploaded to GitHub or the NTU Data Repository.
- [[dataset]]: Datasets or replication data for the publication stored on the NTU Data Repository.
- [[video]]: Presentation video on YouTube explaining or describing content within the publication.
- [[demo]]: Demos on YouTube showing an embodiment of the system described within the publication.
- [[xxxxx]]: Other types of resources, where "xxxxx" is replaced with a suitable descriptor.
