Computer vision is a science which uses cameras and computers to "see" and "understand" the world. Research related to computer vision attempts to establish artificial intelligence systems to obtain "information" from image data. The "information" here is defined by Shannon which can be used to help make a "decision". Because perception can be regarded as extracting information from sensory signals, computer vision can be considered as a science that study how to make artificial system "perceive" from images or multi-dimensional data. This year we will focus on an elementary hands-on introduction to neural networks and deep learning. Topics covered will include: linear classifiers; multi-layer neural networks; back-propagation and stochastic gradient descent; convolutional neural networks and their applications to computer vision tasks like object detection and dense image labeling; generative models (generative adversarial networks and diffusion models); sequence models like recurrent networks and transformers; applications of transformers for language and vision; and deep reinforcement learning.
