Deep Learning is a subset of Machine Learning and Artificial Intelligence, and is one of the most promising developments in the field of AI research. It works with a tremendous amount of data to manage complex tasks such as speech recognition, image classification, and translations, rather than making predictions like conventional machine learning. Deep Learning uses deep neural networks to mimic human intelligence, and its algorithms are layered with increasing complexity. Top firms across industries are increasingly moving towards deep learning due to its potential for growth.
