Summary  
This chapter covers sequence preprocessing—tokenizing text into numeric codes, creating a fixed‐length input via padding and trimming—and building an LSTM‐based neural network with embedding, dropout, a binary output layer, plus a training loop featuring gradient clipping and early stopping for binary classification.

General domain of usage  
Sentiment analysis

A **sentiment analysis model** is built using an **LSTM (long short-term memory)** architecture with the goal of classifying text into positive or negative sentiment. The **IMDB dataset** of movie reviews is used, and several steps are followed to train and evaluate the model effectively.


In summary, this chapter walks through the process of building, training, and evaluating an **LSTM-based sentiment analysis model**. We focus on essential techniques like model architecture design, training configuration, early stopping, and gradient clipping to ensure that the model performs well on the sentiment classification task.

What is the purpose of the **embedding layer** in the sentiment analysis model?
