Alphabet's Google Combines AI Research Units Brain and DeepMind

Alphabet Inc.'s Google merged its two main artificial-intelligence research units, a major reshuffling as tech companies jockey for leadership in an area quickly reshaping business. Google said the new unit, Google DeepMind, would combine the existing Google Brain and DeepMind research groups into one team. The unit will be led by Demis Hassabis, the co-founder and CEO of DeepMind, which Google purchased for about $500 million in 2014.
