Summary  
This chapter introduces time series forecasting using recurrent neural networks (specifically LSTM and GRU), covering how to prepare sequential data, train the model, and evaluate its ability to predict future values.  

General domain of usage  
Finance

The concept of **time series forecasting** is introduced with a focus on its application in **stock exchange prediction**. Time series forecasting involves predicting future values based on previously observed data points, making it valuable in fields such as finance, weather forecasting, and inventory management.


**Time series analysis** is the process of analyzing data that is collected sequentially over time. It involves identifying patterns, trends, and seasonality within the data to forecast future values.

Definition

### Challenges
Time series forecasting, especially for stock prices, involves complexities like **noise**, **market volatility**, and **external factors**. The success of the prediction model depends on the quality of the data and the model's ability to capture underlying patterns.

In summary, time series forecasting is an essential tool in predicting future stock prices and making informed decisions in financial markets. The key steps—data collection, preprocessing, model selection, training, and evaluation—form the foundation of a successful forecasting project.
