The document summarizes deep learning technology and the COCO framework. It discusses that deep learning is a subdomain of machine learning that uses neural networks to process large amounts of data. The COCO framework was introduced by Microsoft to recognize 2D and 3D objects in images using a hierarchical labeling approach based on blockchain technique. The COCO dataset contains over 2.5 million labeled instances across 328,000 images for 91 object categories. Future applications of deep learning and blockchain are discussed, such as in banking, finance, and internet hosting.
