Introduction
One important area of machine learning research has been stock market prediction. Regression, classifier, and support vector machine (SVM) are a few examples of machine learning methods that are used in stock market prediction. This article provides a basic example of applying machine learning to forecast and analyze stock market predictions. Random Forest is a potent tree-based method for stock price prediction, and the case study centers on a well-known online retailer.
we examine the use of machine learning for stock market prediction, focusing on a machine learning project that predicts stock prices and shows how efficient algorithms can improve stock prediction accuracy. We will also propose a stock price prediction Python approach to provide a useful application of the ideas mentioned.
Learning Goals
The best approaches for stock price prediction using long-short-term memory (LSTM) for time series forecasting will be covered in this lesson.
We shall discover all there is to know about LSTM-based stock market prediction.
The Stock Market: What Is It?
The group of markets where investors purchase and sell stocks and other assets is known as the stock market. Shares of ownership in publicly traded corporations are available for purchase and sale on the stock market. By purchasing a company's shares at a discount and then selling them for a higher price, investors can profit. The global economy depends heavily on the stock market, which provides capital for company expansion and growth.
What is Stock Market Prediction? [Problem Statement]
The value of Microsoft's equities, which are traded on NASDAQ, is updated each working day. It should be mentioned that trading is prohibited on Saturdays and Sundays in the market. As a result, there is a space between the two times. Each date is followed by the stock's Opening Value, its Highest and Lowest values on the same day, and its Closing Value at the end of the trading day. Machine learning algorithms for stock market prediction can benefit from this data analysis.
Too technical? The stock's worth after dividends are declared is reflected in the Adjusted Close worth. Moreover, the aggregate volume of equities traded on the market is supplied.
Stock Market Prediction Using the Long Short-Term Memory Method
Step 1: Bringing in the Libraries in Step One
It is common knowledge that the initial stage involves importing the necessary libraries for preprocessing Microsoft Corporation stock data as well as the additional libraries needed for building and displaying the outputs of the LSTM model. For this, we will use the TensorFlow framework's Keras module.
Step 2: Utilizing the Data for Stock Market Prediction Visualization
We will download the stock data as a Comma Separated Value (.csv) file from the local system and save it to a Pandas DataFrame using the Pandas Data Reader module. Lastly, we will review the information.
Step 3: Using the Data Frame Shape to Print the Null Value Check
Initially, we shall print the dataset's structure in this phase. Next, to make sure there aren't any, we'll look for null values in the data frame. The presence of null values in the dataset creates problems for training since they act as outliers and induce a large variance in the training procedure.
Step 4: The True Adjusted Close Value Plot
The ultimate output value that will be predicted by the machine learning model is called the Adjusted Close Value. This number represents the closing price of the stock on that specific day of trading on the stock market.
Step 5: Deciding on the Features and Target Variable
In the next step, the output column is assigned to the target variable. This is the Microsoft Stock's adjusted relative value in this particular scenario. In addition, we select the attributes that act as the independent variable for the dependent variable, or target variable. For training purposes, we select four attributes to account for:
- Open
- High
- Volume
- Low Volume
Step 6: Grading
We're going to scale the stock values to be between 0 and 1, which will reduce the computing cost of the data in the table. Therefore, there is a reduction in all of the large data sets, which in turn results in less memory usage. Scaling down also allows us to attain more precision because the data is not distributed across large numbers. Our tool of choice for doing this is the sci-kit-learn library's MinMaxScaler class.
Step 7: In stock market prediction, create a training set and a test set.
Splitting the dataset into training and test sets is necessary before adding the whole collection to the training model. Training with the training set's data will be done on the Machine Learning LSTM model.
Our tool of choice to do this is the sci-kit-learn library's TimeSeriesSplit class. The 10% of the data used as the test set and the remaining 90% to train the LSTM model will be combined into one split with several 10 splits. By analyzing data samples at regular intervals, this Time Series split has a benefit.
Step 8: Processing Data for LSTM
The data will be entered into the LSTM model once the training and test sets have been finalized. Before doing that, we need to arrange the data from the training and test sets so that the LSTM model can understand them. The training and test data are first converted to NumPy arrays since the LSTM requires the data to be supplied in three dimensions. They are then reorganized to comply with the format (Number of Samples, 1, Number of Features). Now, 90% of 7334 samples, or 6667 samples, make up the training set, and there are 4 characteristics. To account for this, the training set is modified (6667, 1, 4).
Step 9: Develop the LSTM Model for Predictive Stock Market Data
At last, we reach the stage of building the LSTM Model. This stage will involve creating a Sequential Keras model using a single LSTM layer. The Dense Layer, which consists of a single neuron, comes after the 32-unit LSTM layer.
Step 10: The Stock Market Prediction Model's Training
Using the fit function, the LSTM model constructed above is then trained on the training data for 100 epochs with a batch size of 8.
Step 11: Predicting using the LSTM
We can now utilize our model, which was trained using the LSTM network on the test set, to anticipate the Adjacent Close Value of the Microsoft stock.
Step 12: Comparing the True and Predicted Adjusted Close Values
After projecting the test set's values, we can now compare Adj Close's true values and predicted values using the LSTM Machine Learning model by displaying the graph.
In conclusion
The most recent market research and stock market prediction utilizing machine learning improvements have started to integrate such approaches in evaluating stock market data, though, since the advent of machine learning and its powerful algorithms. Each date is followed by the stock's Opening Value, its Highest and Lowest values on the same day, and its Closing Value at the end of the trading day.
