Deep Learning vs Machine Learning

There is a lot of confusion about how deep learning evolved or even how it differs from other artificial intelligence (AI) technologies, and its real-world application. So, I thought I would take a moment to explain the differences between Deep Learning and Machine learning and a little about its evolution. Despite the tremendous success of deep learning in the past few years, the barrier of entry into deep learning remains extremely high, due to numerous reasons. Deep learning is a family of tens of algorithms which is complex to understand and difficult to implement. Even if a full implementation is available, it is irrelevant if not implemented entirely on Nvidia's GPUs, which are by orders of magnitude faster than CPUs.
