Deep learning has profoundly impacted many areas of machine learning. However, it took a while for its impact to be felt in the field of recommender systems. The increasingly sophisticated field of artificial intelligence (AI) has grown and spawned several disciplines that deserve their own focused consideration, namely machine learning (ML) and the ML subset "deep learning." As it sounds, deep learning is the process of leveraging data analytics and the latest gains in computing power to enable computers to observe, learn, and respond to relatively complex situations faster than humans can...
