What is deep learning? Everything you need to know

Here's how it's related to artificial intelligence, how it works and why it matters. Deep learning is a subset of machine learning, which itself falls within the field of artificial intelligence. Artificial intelligence is the study of how to build machines capable of carrying out tasks that would typically require human intelligence. That rather loose definition means that AI encompasses many fields of research, from genetic algorithms to expert systems, and provides scope for arguments over what constitutes AI. Within the field of AI research, machine learning has enjoyed remarkable success in recent years -- allowing computers to surpass or come close to matching human performance in areas ranging from facial recognition to speech and language recognition. Machine learning is the process of teaching a computer to carry out a task, rather than programming it how to carry that task out step by step. At the end of training, a machine-learning system will be able to make accurate predictions when given data.
