Suicidal ideation detection in textual data has emerged as a critical area of research, with implications for mental health support and intervention. This study presents a novel approach that integrates ensemble modeling and keyword-based categorization to improve the detection and analysis of suicidal tendencies in text. Using a labeled dataset with balanced class distribution (10,009 suicide and 9,988 non-suicide instances), we performed comprehensive preprocessing, including the removal of URLs, mentions, hashtags, emojis, stopwords, and applying lemmatization and tokenization. Features were extracted using CountVectorizer, and multiple machine learning models, including K-Nearest Neighbors (KNN), SVM, Naive Bayes, Decision Tree, Logistic Regression, and LSTM, were evaluated. An ensemble model combining KNN, Naive Bayes, and Decision Tree achieved the highest binary classification accuracy of 94.87%, demonstrating its superiority. Our novelty lies in the creation of a new dataset by leveraging the ensemble model to identify suicide-related text and categorizing entries into explicit, implicit, help-seeking, and emotional distress categories using domain-specific keywords. Multi-class classification on this enriched dataset was performed using advanced algorithms, including XGBoost, CatBoost, and LightGBM, with LightGBM achieving the highest 96.32% accuracy. This innovative integration of ensemble modeling and keyword-based categorization highlights the potential for enhancing suicidal ideation detection and mental health monitoring systems.

Analytical resume is the best tool used to deeply and thoroughly evaluate any candidate resume by considering various elements like education, work experience, and skills. This approach incorporates different angles that complement one another to build the entire profile of the professional identity and prospects of the candidate. By means of the improvement of specific areas, e.g. formatting, language usage, and personal brand, holistic analysis is able to provide an employer with powerful resume content that efficiently presents a candidate's value proposition to the employer. It tells the reader how a resume not only reveals qualifications but also fits well with the desired audience. The analysis not only examines how the document is designed and if the experiences listed are relevant, but it also considers if the language used is appropriate, the whole package of which a candidate produces for recruiters. Holistic resume analysis addresses and points out possible omissions or inconsistencies that may adversely affect the profile of a candidate, thereby serving as a catalyst to his or her improvement. The holistic resume analysis mainly serves as a guide for job seekers to better their applications and at the same time it is a hiring manager's instruction for understanding that a candidate's skills must coincide with the organization's requirements at a given time. By bringing together the data and people. This analysis helps the hiring manager to benefit more in regard to taking right decisions that will ensure that the best firms and the right people will meet and work together. In a highly competitive job market, a comprehensive review of such details is the main means of getting ahead and thus it is the only means of successfully overcoming the pitfalls that intermingle in the promising career field.

The main purpose of this research shall be to assess the suitability of applying internships when estimating students' employability through machine learning techniques. One analysis was done using a new database containing 1000 records with the variables of General Point Average (GPA), number of internships, supervisor ratings, organization type, employment offer status and demographic data. The data collection took place among structured undergraduate students who participated in business internship programs as their course requirements. In this study, eight machine learning methods were evaluated, including Random Forest (RF), Gradient Boosting, AdaBoost, Multi-Layer Perceptron (MLP), Gaussian Naive Bayes (GNB), XGBoost, k-Nearest Neighbors (KNN), and LightGBM. The alumni employability outcomes were predicted using these models and assessed based on four measures: accuracy, precision, recall, and F1-score. Among these models, Gaussian Naive Bayes demonstrated the highest performance, with an accuracy of 65% and an F1-score of 65.02%. AdaBoost also performed relatively well, achieving an accuracy of 59% and an F1-score of 58.89%. In contrast, the other models exhibited varying levels of performance. Random Forest achieved an accuracy of 52%with an F1-score of 52.04%, while XGBoost performed the worst, with an accuracy and F1-score of 49%. These results underscore the need to consider some internship characteristics, including task content and relevance, ratings for intern performance, and subsequent employment opportunities as critical dimensions in employability. While the obtained accuracy values suggest directions for enhancing the use of machine learning models to estimate internship effectiveness and determine essential factors influencing the graduate employability, this research confirms the continuing relevance of the field. The findings suggest the need for further research trying to improve the accuracy of the existing predictive models for practical use

Fraud detection in smart grids is critical to ensure reliable and efficient energy distribution, preventing significant financial losses and maintaining grid stability. This project presents an advanced fraud detection system utilizing deep neural networks (DNN) to automatically identify and prevent fraudulent activities such as energy theft, meter tampering, and unauthorized energy consumption. The DNN model processes vast amounts of data generated by smart meters and other grid sensors, learning complex patterns and anomalies that indicate potential fraud. By integrating feature extraction techniques and real-time monitoring, the system is designed for scalability and accuracy, capable of handling high-dimensional data from modern energy grids. Additionally, this solution improves the grid's resilience and operational efficiency by enabling proactive fraud detection and reducing false positives, helping utility companies safeguard their assets.
