Apple Just Hired This Artificial Intelligence Expert by Jonathan Vanian @FortuneMagazine October 17, 2016, 4:06 PM EDT E-mail Tweet Facebook Linkedin Share icons Apple continues to bulk up on artificial intelligence and data crunching smarts. Ruslan Salakhutdinov, an associate professor at Carnegie Mellon University and its computer science school’s machine learning department, said Monday via Twitter that he is joining Apple aapl as its director of A.I. research. He will continue to work at Carnegie Mellon while at Apple. Excited about joining Apple as a director of AI research in addition to my work at CMU. Apply to work with my teamhttps://t.co/U2hQl2GdhA — Russ Salakhutdinov (@rsalakhu) October 17, 2016 Among Salakhutdinov’s areas of research is the hot field of deep learning, an A.I. technique in which software systems called neural networks are given vast quantities of data to find patterns within. Get Data Sheet, Fortune’s technology newsletter. The rise of cloud computing—with its ability for companies to more easily store tremendous amounts of data—coupled with the use of graphics processing units (GPUs) and specialized computer chips to process the information has led to big breakthroughs in deep learning. For example, computers have learned to spot images like cats in photos and recognize speech. Many digital assistants like Apple’s Siri, Microsoft’s msft Cortana, and Amazon’s amzn Alexa are powered in some ways by artificial intelligence to better understand people’s voices and answer questions and act on their requests. Apple’s new hire is just the latest from the technology company that some A.I. experts have said is behind other tech companies like Google goog and Facebook fb when it comes to A.I. talent and capabilities. Huge get for Apple. Russ does amazing research. Does this mean Apple will publish papers now? Otherwise their gain is the world's loss. https://t.co/VWoz14YJh6 — Jack Clark (@jackclarkSF) October 17, 2016 In August, Apple bought a machine-learning startup Turi in a deal reported to be worth roughly $200 million. Just one month later, Apple purchased another machine-learning startup Tuplejump, but the deal’s value was not disclosed.
