深度学习：模拟人类神经网络的机器学习方法

Deep learning is a machine learning method that simulates the structure and working principles of the human neural network, using multi-layered neural networks to analyze and process data. Deep learning can be applied to various fields, such as natural language processing, image recognition, speech recognition, etc. Among them, visual localization is one of the important applications of deep learning in the field of image recognition.
