My name is Jinyu Xie. I am a senior research engineer in Google DeepMind Robotics Team, and a Ph.D. in Control Systems and Artificial Intelligence. Before Google DeepMind, I was a Ranking Engineer in Google Search.

This is my blog site to keep my learning notes.

Some of the works done by me in Google:

• Few shot adaptation finetuning experiments (Fig. 26) in Gemini Robotics Technical Report:

• Gemini Robotics On-Device finetuning service and sdk (github.com/google-deepmind/gemini-robotics-sdk) for Trusted Testers. Demo videos (edited by myself):
• Topic-Authority-based Ranking algorithm for Google Search.

I love building tools. Whenever I found there are no tools that fit my use case nicely, I will start building my own. Here are some of the tools I built:

• loopquest.ai, a MLOps Web App for Embodied AI evaluation. I am using it heavily for my offline reinforcemen learning workflows, and I host this on the cloud in case others would like to use it as well.
• simglucose, a Type-1 Diabetes Simulaotr with OpenAI Gym interface. It seems to be the most popular open-source type-1 diabetes simulator? Here are the google scholar search results.
• fireTS a multi-variate time series prediction library. There is no python packages that are as usable as the Matlab one for system identification and time series prediction. I built a similar one with similar APIs, but take it a mile away to connect the interfaces with different machine learning packages, e.g. sklearn, pytroch, as the core.
