Artificial Intelligence & Machine Learning
How can a computer come up with new concepts? Can it detect a new meaning of a word? I've solved the long-standing problem of coming up with new concepts automatically, and won the award for the best PhD dissertation granted by the European Association for Artificial Intelligence. This led to deep neural networks, and all the AI we have today: the LLM systems have formed statistical concepts by observing the data of the open world wide web.
Technology Entrepreneurship
It's rare for a new technology to become a successful business, and it's rare for an existing business to successfully develop a lasting technological advantage. I've dedicated my career to straddling between these two domains, and can help businesses bring new technologies to market, and retain their technological edge. I've started several companies, and non-profit organizations both in the US as well as in the EU.
Data Science & Bayesian Statistics
Data is one of the greatest advances in science: it elevates us above the hear-say, and affords us the rigor of science. I've redesigned the course on data science at Columbia University in the City of New York around an applied approach that integrates both machine learning and statistics. I've pioneered the use of data flow user interfaces in data science with the Orange data science platform.
