I develop and deploy AI models for Machine Translation (MT).Insights:• Language Expansion: I lead the project to expand the number of supported languages by our MT from 56 to 201, making it the first commercial translation engine in the world with such extensive language support.• Trust Attention: I had the intuition for a novel technique that prioritises the most valuable training data. This approach played a pivotal role in significantly enhancing the quality of machine translation, resulting in improvements unseen in the past five years.• LLM-based translation model: I am currently working in a new team specifically dedicated to build the next generation of machine translation with a different paradigm based on Large Language Model.
