This is the data point that the recurrent neural network is trying to predict.
One data structure that we'll call x_training_data that contains the last 40 stock price observations in the data set.It's done through creating two special data structures: So how do we actually specify the number of timesteps within our Python script? Note that since there are only ~20 trading days in a given month, using 40 timesteps means we're relying on stock price data from the previous 2 months. This means that for every day that the neural network predicts, it will consider the previous 40 days of stock prices to determine its output. We will use 40 timesteps in this tutorial. Timesteps specify how many previous observations should be considered when the recurrent neural network makes a prediction about the current observation. The next thing we need to do is to specify our number of timesteps. reshape ( - 1, 1 ) ) Specifying The Number Of Timesteps For Our Recurrent Neural Network Let's start our Python script by importing some of these libraries: This tutorial will depend on a number of open-source Python libraries, including NumPy, pandas, and matplotlib. Importing The Libraries You'll Need For This Tutorial Once the files are downloaded, move them to the directory you'd like to work in and open a Jupyter Notebook. They look like this (when opened in Microsoft Excel):
