This document provides an overview of deep learning presented by Khaled Amirat at the University of Souk Ahras in Algeria in 2017. It defines artificial intelligence and machine learning, and explains that deep learning is a type of machine learning that uses neural networks with multiple layers to automatically learn representations of raw data. The document contrasts deep learning with traditional machine learning approaches that require manual feature engineering, and outlines different deep learning architectures like convolutional neural networks and recurrent neural networks. Examples are given of applications in areas like computer vision, natural language processing, and topic modeling from documents. The training process of neural networks using forward propagation and backpropagation is also summarized.
