That Post-Academia Thing I Needed to Write.

Two and a half-years ago I jumped off the AI bandwagon, left a permanent position in academia to joined "the industry," namely Zalando, a big European fashion ecommerce retailer. On the other hand, ever since I left, AI really did explode, with NIPS 2017 selling out in  15 days, and absurdities happening like Intel AI … Continue reading That Post-Academia Thing I Needed to Write. →

Data Analysis: The Hard Parts

Projects like Pandas or scikit-learn are open source, free, and allow anyone with some Python skills do lift some serious data analysis. Projects like MLbase or Apache Mahout work to make data analysis scalable such … Continue reading Data Analysis: The Hard Parts →

Three Things About Data Science You Won’t Find in the Books

How Python Became the Language of Choice for Data Science

Nowadays Python is probably the programming language of choice (besides R) for data scientists for prototyping, visualization, and running data analyses on small and medium sized data sets. And rightly so, I think, given the large number of available tools (just look at the list at the top of this article). However, it wasn’t always … Continue reading How Python Became the Language of Choice for Data Science →

AI’s Road to the Mainstream – 20 Years of Machine Learning

When I enrolled in Computer Science in 1995, Data Science didn’t exist yet, but a lot of the algorithms we are still using already did. And this is not just because of the return of the neural networks, but also because probably not that much has fundamentally changed since back then. At least it feels … Continue reading AI’s Road to the Mainstream – 20 Years of Machine Learning →
