A popular and interesting book about the search for a universal self-learning algorithm from a practicing scientist. Algorithms drive our lives. They find books, films, jobs and partners for us, manage our investments and develop new medicines. These algorithms are increasingly trained on the basis of the data arrays that we leave behind in the modern digital world. Like curious children, they watch us, imitate and experiment. And leading laboratories and universities are working on creating the main self-learning algorithm that can extract any knowledge from the data and solve any problems - even before we formulate them. Machine learning allows smart robots and computers to program themselves. This is one of the most important modern technologies - and it is also one of the most mysterious.
