One of the hot trends in artificial intelligence (AI) revolves around the use of deep learning (DL) technologies for image and video classification. These AI-driven applications use computer vision to classify or categorize an image or video file on the basis on its visual content. So, what is deep learning? In a few words, DL is a subset of machine learning (ML), and one of the key building blocks for AI solutions. It uses artificial neural networks as the underlying architecture for training algorithms, or models.
