Due to the unpredictability of stock market, accurate prognostic models are necessary for investing. In recent years, machine learning techniques, specifically deep algorithms, have grown in popularity predicting prices. This paper seeks compare stock-price forecasting abilities several models, including LSTM, Bi-LSTM, and GRU. The algorithms make use capabilities Recurrent Neural Networks (RNNs), with a particular emphasis on Long-Short Term Memory (LSTM) model. primary objective is evaluate accuracy these at market values determine how number training epochs affects model performance. Through comparative analysis, we intend identify most Using historical data, research involves evaluating various models. Common evaluation metrics, such as Root Mean Square Error (RMSE), Squared (MSE), Absolute (MAE), used performance each terms RMSE, MSE, MAE, bi-LSTM outperforms other obtaining 0.00029, 0.01 respectively.

The prediction of stock market prices based on the financial text sentiment classification using Machine Learning (ML) and Deep (DL) models is becoming popular among researchers in era Big Data (BD). Nevertheless, owing to lack extensive analysis, most developed ML DL failed achieve better results. Thus, for real-time polarity price, a Probability Tanh-Independently Recurrent Neural Network (PT-IndRNN)-based data Twitter proposed solve this problem. Primarily, by employing corresponding API, are extracted stored MongoDB database Apache Flume. This with historical big datasets taken pre-processed. Next, deploying Hadoop Distributed File System (HDFS) clustering, pre-processed real-time, as well dataset, combined separately. After that, features from clustered sentences. Then, utilizing Senti Word Net, sentences chosen Linear Scaling-Dwarf Mongoose Optimization Algorithm (LS-DMOA) converted negative positive scores. In end, texts classified PTh-Ind RNN, which proved obtaining reliable result values.
