The importance of forecasting stock values has increased in the domain of engineering's use of cognitive computing. Utilizing data-driven tactics for forecasting stock prices, investors can effectively mitigate risks and enhance profits. Investors can use projections based on historical values and textual data to make well-informed judgments about future patterns in stock prices. Stock price anticipation is a pivotal undertaking in the financial sector that has substantial consequences for traders and investors. This article presents an in-depth comparison analysis of machine learning tactics for forecasting price fluctuations in stocks. The research deploys historical stock data and diverse technical indicators. This paper presents the Gated Recurrent Unit (GRU) model for Nasdaq stock index anticipation, which is optimized by Particle swarm optimization (PSO), Biogeography-based optimization (BBO), and Moth flame optimization (MFO). Among these optimizers, MFO has the best outcomes. Compared to the GRU scheme the optimized PSO-GRU, BBO-GRU, and MFO-optimized GRU for stock forecasting has the outcomes of 0.9807, 0.9824, and 0.9904 in coefficient of determination (<span>({R}^{2})</span>) which shows the improvement of the presented scheme as a result of its development.

In this research, we design a Machine Learning (ML)-based predictive system using six ML models namely Logistic Regression, Random Forest, Gradient Boosting (GB), Decision Tree, Support Vector Machine, and K-Nearest Neighbors and evaluate their performances using accuracy, precision, recall, and f1 score. This system predicts employee attrition in advance, allowing organizations to implement proactive talent management strategies instead of relying on traditional reactive approaches. We analyse ‘IBM HR Analytics data’, that contains 1,470 observations and 35 features. Among all the models, GB outperform others with 98% accuracy, and precision, 100% recall and 99% f1 score. Furthermore, using Explainable AI (XAI) methods such as ELI5, SHAP, LIME, and SHAPASH, we analyze the most influencing factors related to employee attrition.

In this paper, a hybrid learning approach is presented that integrates machine learning and deep learning models to enhance the accuracy and robustness of visual facial emotion recognition in speech videos.
