About Wenda Xu
I am a research scientist at Google Deepmind. I work on Gemini evaluation and post-training. My research focuses on improving large language models (LLMs) through rigorous evaluation and post-training. I actively work on speech translation, audio edits and cross-lingual transfer. I developed automated methods to assess model capabilities, including scalable and efficient data curation technique for building model-specific challenge benchmarks. During PhD, I designed unsupervised and explainable evaluation metrics. My work in this area led to SEScore1 & 2 and InstructScore, which was recognized as the best unsupervised metric at the WMT22 shared task. My background also included developing efficient post-training techniques, from preference learning with BPO to knowledge distillation with Speculative KD.I received PhD in Computer Science from the University of California, Santa Barbara. My advisors are Prof. William Wang and Prof. Lei Li.
