Profile bio
About Valentin Hartmann
Currently using my skills in ML and NLP to enable a new paradigm of language learning.In my research, I have worked with Microsoft and Cliqz. With Cliqz, I have developed and implemented a method for federated learning that was deployed in their browser. I have published on topics as diverse as federated learning, large language models, differential privacy and optimal transport.Since I noticed that my mind expands when my muscles contract, I like to go on long bike rides of up to 300 km, which is where I have my best ideas.
