WHAT HAPPENS WHEN COMPUTERS START TO LEARN ON THEIR OWN How do computers learn something new? One might say programming, but it involves telling the computer every little step that it needs to perform in order to complete the new task. You need to know the steps yourself in order to teach the computer. However, what do you do when you don’t know the steps yourself? This is where machine learning comes in. With this technology, the computer is made to learn things and processes on its own. Jeremy Howard is a specialist in this field. He gave a TED Talk to show how much machine learning has evolved and how it will begin to affect the world at large. The first example of machine learning took place in 1956 when a guy named Arthur Samuel wanted his computer to be good enough at checkers to beat him. His solution was to make the computer keep playing checkers against itself and learning from the games. Suffice to say, it worked so well that the computer ended up defeating the state champion of Connecticut. Today, examples of machine learning are all around us. The most common application is the search engine. Google makes use of machine learning to get its search engine locate the information that you actually want. Remember those recommendations shown in Amazon? Those recommendations are provided by machine learning algorithms. Pretty nifty, right? Well, it can be creepy too like those friend recommendations in LinkedIn. Take for example the team which created a computer program for automatic drug discovery. What’s cool is that the team did not have any knowledge in biology or medicine. They simply used what is called deep learning. Deep learning allows computers to actually learn Chinese. Now, what does that mean for people and their jobs? We might be heading into another Industrial Revolution, except, the results might not pretty. After all, deep learning will allow computers to perform 80% of human jobs easily. JULY 2016 Future Cities & Robotics 23
