About me
I am a Postdoc at The University of Edinburgh Institute for Languages, Cognition and Computation, with Kenneth Heafield. I completed my PhD in the same institute with Adam Lopez and Kenneth Heafield.
I like languages, logographic writing systems, game theory and GPUs. I (try to) make things run faster and enjoy (premature) optimization. In my spare time I learn languages and play football. Please check out my blog where I post random things about Chinese characters, code and life.
Research
My research lies at the intersection of high performance computing and NLP. I am interested in GPGPU, low level CPU GEMM routines, NLP, in particular Neural Machine Translation, transformers, word embeddings, transfer learning and multilinguality. Lately, I have been working on optimising Neural Machine Translation inference, both on CPUs and GPUs.
Projects
I am an avid supporter and believer in Open Source software and have contributed to various projects, among which:
- Various contributions to the marian machine translation framework.
- 8 bit integer GPU TensorCore decoding
- 8 bit integer CPU decoding
- Paraphraser, work together with Pinzhen Chen.
- Forced decoder for parallel corpora mining, work together with Pinzhen Chen.
- translateLocally a cross-platform desktop offline machine translation software.
- OpusCleaner and OpusTrainer modern machine translation data cleaner and trainer, built together with Jelmer van der Linde.
- Privacy focussed machine translation with Firefox.
- gemmBench a benchmark framework for various low precision GEMM frameworks.
- Collaborator on intgemm an 8 and 16bit intger GEMM framework by Kenneth Heafield.
- bfTile, an experimental VNNI GEMM tiling.
- imageSelector a cross-platform photo library organiser.
- gLM a GPU n-gram language model.
- ProbingPT a probing phrase table for statistical machine translation.
