Deep learning uses multi-layer neural networks for complex pattern-recognition tasks. It is especially relevant to areas such as computer vision, speech and natural language processing. The practical value of deep learning becomes clearer when you use it to solve an actual problem instead of studying definitions alone. This point is specifically relevant to the deep learning aspect of MCA study. For this specific question about deep learning, the practical takeaway is to relate the concept to your own MCA learning goal. In other words, this guidance addresses: Is deep learning difficult for MCA students?
