1. Tech giants investing in AI: Google
In 2014, Google bought artificial intelligence startup DeepMind for a huge $400 million (£263 million), making it one of the largest AI acquisitions to date.
This week, Google DeepMind has created an AI project that uses reasoning to conquer the London Underground. In a paper published by Nature, it explained how the AI and human-like mind could find the quickest route between underground stations, using neural networks to store data and recall information to solve problems.
For example, it could work out where passengers would end up if they took the tube from Holloway Road, two stops and the Victoria in the opposite direction four stops.
What's more, earlier this year Google announced that its machine learning system TensorFlow will be available free for everyone. Machine learning can be found in image and speech recognition technology and translation applications. It mimics the way the human brain works and recognises patterns.
