1. Title:PREDICTING STOCK MARKET TRENDS USING MACHINE LEARNING AND DEEP LEARNING ALGORITHMS VIA CONTINUOUS AND BINARY DATA; A COMPARATIVE ANALYSIS
2. FieldofInvention:Machine learning and deep learning algorithms for financial market prediction
3. Abstract:
The nature of stock market movement has always been ambiguous for investors because of various influential factors. This study aims to significantly reduce the risk of trend prediction with machine learning and deep learning algorithms. Four stock market groups, namely diversified financials, petroleum, non-metallic minerals, and basic metals from the Tehran stock exchange, are chosen for experimental evaluations. This study compares nine machine learning models (Decision Tree, Random Forest, Adaptive Boosting (AdaBoost), eXtreme Gradient Boosting (XGBoost), Support Vector Classifier (SVC), Naïve Bayes, K-Nearest Neighbors (KNN), Logistic Regression and Artificial Neural Network (ANN)) and two powerful deep learning methods (Recurrent Neural Network (RNN) and Long short-term memory (LSTM).Ten technical indicators from ten years of historical data are our input values, and two ways are supposed to employ them. Firstly, calculating the indicators by stock trading values as continuous data, and secondly converting indicators to binary data before using. Each prediction model is evaluated by three metrics based on the input ways. The evaluation results indicate that for the continuous data, RNN and LSTM outperform other prediction models with a considerable difference. Also, results show that in the binary data evaluation, those deep learning methods are the best; however, the difference becomes less because of the noticeable improvement of the model's performance in the second way.

4. Background: Stock market prediction has always been a complex and challenging task due to the market's inherent volatility, complexity, and the influence of various unpredictable factors such as investor sentiment, political events, and economic conditions. Traditionally, stock market predictions were conducted using fundamental and technical analysis. Fundamental analysis involves evaluating a company's financial health, market position, and growth potential, while technical analysis focuses on historical price patterns and trading volumes to forecast future price movements.With the advent of data science, machine learning (ML), and deep learning (DL) techniques, the landscape of stock market prediction has evolved significantly. These advanced computational techniques offer new opportunities to analyze large datasets, identify complex patterns, and improve prediction accuracy. Machine learning algorithms, such as Decision Trees, Random Forests, Support Vector Machines (SVM), and K-Nearest Neighbors (KNN), have demonstrated effectiveness in stock trend prediction due to their ability to learn from historical data and make data-driven predictions. These models can handle non-linear relationships and interactions among features, providing better prediction accuracy than traditional methods.

5. Objective of Invention: The primary objective of the invention "PREDICTING STOCK MARKET TRENDS USING MACHINE LEARNING AND DEEP LEARNING ALGORITHMS VIA CONTINUOUS AND BINARY DATA: A COMPARATIVE ANALYSIS" is to enhance the accuracy and reliability of predicting stock market trends by comparing the performance of various machine learning and deep learning models. The study aims to evaluate the effectiveness of nine machine learning algorithms (such as Decision Tree, Random Forest, XGBoost, etc.) and two deep learning methods (RNN and LSTM) using two approaches for input data: continuous data (stock trading values) and binary data (preprocessed continuous data). By using ten technical indicators from ten years of historical data from four stock market groups of the Tehran Stock Exchange, the study seeks to determine which models and data preprocessing methods most effectively predict stock market movements, thereby reducing investment risks for traders and financial analysts.


6. Summary of the invention:"PREDICTING STOCK MARKET TRENDS USING MACHINE LEARNING AND DEEP LEARNING ALGORITHMS VIA CONTINUOUS AND BINARY DATA: A COMPARATIVE ANALYSIS" presents a novel approach to predicting stock market trends by employing a combination of machine learning and deep learning algorithms on continuous and binary data. The invention focuses on improving the prediction accuracy of stock market movements by analyzing historical data from the Tehran Stock Exchange, encompassing four key stock market groups: diversified financials, petroleum, non-metallic minerals, and basic metals.
The study proposes using ten technical indicators derived from ten years of historical stock trading data as inputs to the prediction models. The authors explore two distinct approaches to handling input data:
Continuous Data: Utilizes raw stock trading values such as open, close, high, and low prices.
Binary Data: Involves preprocessing the continuous data to convert it into binary format, where indicators are calculated to represent up or down movements based on stock market properties.
The invention involves a comprehensive comparison of nine machine learning models-Decision Tree, Random Forest, Adaptive Boosting (AdaBoost), eXtreme Gradient Boosting (XGBoost), Support Vector Classifier (SVC), Naïve Bayes, K-Nearest Neighbors (KNN), Logistic Regression, and Artificial Neural Network (ANN)-and two deep learning methods-Recurrent Neural Network (RNN) and Long Short-Term Memory (LSTM).
The results indicate that both deep learning methods, RNN and LSTM, outperform traditional machine learning models when using continuous data. When binary data is used, the performance difference narrows due to the significant improvement in the accuracy of the traditional models. However, the deep learning methods still deliver the best results overall, demonstrating their superior capability to capture complex patterns in stock market data.
This invention's key contribution is the comparative analysis of different machine learning and deep learning algorithms on two types of data representations, highlighting the effectiveness of preprocessing techniques and the advantages of deep learning in stock market prediction tasks. The study provides valuable insights into selecting appropriate models and data handling techniques for financial prediction and investment strategies.
