Hello, my name is

Yi Chern Tan.

I am a researcher and software engineer with experience in machine learning and natural language processing. I am currently @Waymo. I was previously @Facebook and @Yale. I have published on interpretability, fairness, representation learning and semantic parsing at NeurIPS, ICLR, ACL and EMNLP.

I received my BS in Computer Science and Ethics, Politics and Economics from Yale University in 2020. At Yale, I was advised by Dragomir Radev (LILY Lab), Robert Frank (CLAY Lab) and Elisa Celis (Controlling Bias in AI Group). I also worked with John Lafferty to create a curriculum for, and teach, text data science.

My research interests lie in the intersection of language + X ∈ {learning, representation, bias, reasoning} and technology + Y ∈ {ethics, culture, government, security}. In particular, I work on natural language processing and machine learning with the aim of building scalable systems that have a robust understanding of human language, and which are supported both by principled values and elegant engineering.

Apart from research, I also have experience in government and products. At Singapore's Smart Nation and Digital Government Office, I authored strategy papers and analyses on the societal harms of AI and the responsible deployment of human-centered AI systems. At Facebook, I developed transformer-based models for the detection of harmful comments on Instagram and secured the highest tier full-time return offer.

Since my graduation, I've been fulfilling mandatory military service in Singapore, carrying out operations as an "IO" (infantry officer). I am currently a machine learning engineer at Waymo, working on safety benchmarking by detecting collisions in simulation.
