From this chapter, we start the second major area of AI, namely, natural language processing (NLP). We begin the chapter by giving a primer on NLP. We mention the different types of problems addressed by NLP. The chapter then goes on to describe the different steps of a typical NLP project, including converting text data into numerical data, one-hot encodings, and word embeddings. We then describe the encoder-decoder architecture and some of the popular and frequently used neural network approaches to implementing them, like RNNs, LSTMs, and transformers.

摘要

From this chapter, we start the second major area of AI, namely, natural language processing (NLP). We begin the chapter by giving a primer on NLP. We mention the different types of problems addressed by NLP. The chapter then goes on to describe the different steps of a typical NLP project, including converting text data into numerical data, one-hot encodings, and word embeddings. We then describe the encoder-decoder architecture and some of the popular and frequently used neural network approaches to implementing them, like RNNs, LSTMs, and transformers.
