Deep learning basics

As a promising artificial intelligence research branch, deep learning has made numerous breakthroughs in recent years. In many tasks including vision, speech, and text, deep learning greatly outperforms traditional models. The majority of current machine reading comprehension (MRC) models are based on deep learning. This section introduces the basics of deep learning used in MRC, which provides the foundation for many MRC models.

B.1 Neural network

The cornerstone of deep learning is the neural network. A neural network can complete the entire process for MRC: read articles and questions, analyze the semantics, and produce answers. This section describes the definition, computation, and optimization of neural network ...
