About the Author

Hi, I’m Maarten! I have a background in Organizational Psychology and Clinical Psychology and switched over to Data Science to pursue my interests in AI.

After pursuing these degrees, I authored and currently maintain the popular BERTopic, KeyBERT, and PolyFuzz open-source packages which have been downloaded over 5,000,000 times.

Together with my co-author Jay Alammar, we are currently in the process of writing the Hands-On Large Language Models book together with O’Reilly.
