Linear Models for Classification and Regression,Linear models for classification and regression express the dependent variable (or class variable) as a linear function of the independent variables (or feature variables). Specifically, consider the case in which .. is the dependent variable of the .th document, and . are the .-dimensional feature variables of this document.

Text Summarization,Text summarization creates a short summary of a document, which can be easily assimilated by the user. The most basic form of text summarization creates a summary from a single document, although it is also possible to do so from multiple documents.

Text Segmentation and Event Detection,Although text segmentation and event detection might seem like different problems, they are closely related. In both cases, the text in one or more documents is scanned sequentially in order to detect key changes. Therefore, the concept of . is the overarching theme of this chapter.

Attention Mechanisms and Transformers, of the data, so that portions of the data that are most relevant for prediction are emphasized. A classical example of an application of attention occurs in machine translation, where the translation of a specific part of a target sentence often focuses on important parts of the source sentence.
