Google is extending its push into artificial intelligence with a new European research centre dedicated to advancing the technology.
Based in Zurich, the team will focus on three areas - machine learning, natural language understanding and computer perception.
Emmanuel Mogenet, who will head the unit, said much of the research would be on teaching machines common sense.
There was, he said, "no limit on how big I grow the team".
"We are very ambitious in terms of growth. The only limiting factor will be talent," he told journalists gathered in Zurich to hear more about Google's AI plans.
Machine learning is already the "secret sauce" in a lot of Google products, said Mr Mogenet, including search, spam filters, translation and content removal, as well as newer products such as its virtual helper Google Assistant, messaging app Allo and self-driving cars.
"We are on the brink of a brand new era of computing," Mr Mogenet told journalists.
One of the key focuses would be on teaching computers "common sense", he said.
"A four-year-old child learns about the world through their senses so they know that cows don't fly without being told this. Computers need to understand some obvious things about the world so we want to build a common-sense database."
Another key focus will be improving human/machine dialogue.
"Google has always been in the business of natural language because that is how people search but we have never really understood the question. We have just matched keywords with content and rank that content smartly," he said.
"The next stage is to truly understand what people are asking."
Finally, the researchers would delve beneath the bonnet to try to understand "how machines learn and why deep learning works so well", he said.
