Europe’s developers working on deep tech areas such as machine learning

Trends are emerging in the field of deep tech. The proportion of questions on the topic of machine learning posted by developers in Europe using Stack Overflow’s Q&A platform has increased by 80% since 2015. This is a significant uplift compared to the 43% increase recorded between 2014 and 2015.  In 2016, machine learning represents almost 1% of all 723,492 questions asked by professional developers in Europe throughout the year.

Kevin Troy, Director of Stack Overflow Insights, commented:

“The fact that  we have so many developers in Europe is testament to two things — software really is eating the world, and Europe is a hub for exciting technological innovation. The shift towards deep technology underlines the latter. Some of the most cutting edge work in the world of artificial intelligence is being done in London — from the highly publicised players like DeepMind to exciting young startups like Weave.Ai and Tractable.”
