Hybrid approach for multi-class skin cancer classification with DCNN feature and ensemble techniques Maridu Bhargavi, Sivadi Balakrishna Engineering Research Express, 2025 The classification of skin cancer is a critical factor in early diagnosis and treatment. This paper presents a hybrid multi-class skin cancer classification that uses a deep convolutional neural network as the feature extraction model and an ensemble of Histogram Gradient Boosting, Random Forest, and XGBoost classifiers with soft voting for the final prediction. The proposed model achieved a high classification accuracy of 92% on the ISIC dataset and 93% on the PAD-UFES-20 dataset, with corresponding specificity values of 98.92% and 98.75%, respectively. The overall false positive rates were 0.21% and 0.17%, respectively. The precision, recall, and F1-scores also exceeded 91% demonstrating high sensitivity and fairly balanced performance. The false negative rate was also kept relatively low at 1.90% for ISIC and 0.67% for PAD, while the Matthews correlation coefficients(MCC) were quite high at 97.60% for ISIC and 91.85% for PAD. The proposed model is also evaluated on an external dataset, HAM10000, yielding an accuracy of 66.67% confirming generalization capability under a domain shift. This DCNN-ensemble approach to automated skin cancer detection has shown itself to be a solid and scalable solution. Future studies should focus on feature fusion, expanding this approach to more diverse datasets that may encompass different patient populations and analysis, and integrating applications that enable real-time diagnostic support.
Transfer learning based hybrid feature learning framework for enhanced skin cancer diagnosis using deep feature integration Maridu Bhargavi, Sivadi Balakrishna Engineering Science and Technology an International Journal, 2025 Skin cancer continues to be a major health problem worldwide, with excessive misdiagnosis of skin cancer among dermatologists resulting in delayed treatment and poor patient outcomes. To improve survival chances, skin cancer must be identified accurately and promptly. However, current diagnostic methods lack feature representation and model generalization. Among the primary challenges in automated skin cancer classification are addressing differences in lesion appearance, occlusions, and data class imbalance that impact model performance and reliability. To address these issues, this research proposes the DRMv2Net model, a feature fusion deep learning-based technique that integrates multiple pre-trained convolutional neural networks to enhance skin cancer diagnosis. The method applies a systematic pipeline that includes pre-processing, feature extraction, fusion, and classification. The pre-processing techniques such as adaptive thresholding for hair artifact removal, image inpainting to remove occlusions, and data augmentation for class balancing, were applied to enhance the quality of inputs. Using DenseNet201, ResNet101, and MobileNetV2, diverse features like edges, texture, and color change were extracted and concatenated to build a rich feature representation, followed by fully connected layers for classification. The two benchmark datasets, ISIC 2357 and PAD-UFES 20, are used extensively in testing the DRMv2Net model. A comparison with standalone CNN models such as DenseNet201, ResNet101, MobileNetV2, VGG19, and Xception shows that feature fusion had better accuracy results of 96.11 % on ISIC 2357 and 96.17 % on PAD-UFES 20 respectively when compared to values obtained by existing standalone models. These results demonstrate the strength of feature fusion and pre-processing in boosting how accurately skin cancer is identified and offer a robust and scalable automatic medical image classification solution.
AI for Clean Water: Predicting Potability with Machine Learning Karumuri Akhila, Maridu Bhargavi, Akash Ajay Proceedings of 3rd International Conference on Intelligent Cyber Physical Systems and Internet of Things Icoici 2025, 2025 Access to safe drinking water is a huge global problem, with contamination being a major danger to public health. This study proposes a machine learning framework for predicting potability of water using its physicochemical properties, allowing rapid and scalable assessment of water quality attributes. Pre-processing of the Kaggle water potability dataset, made up of 3,276 samples with 9 inputs, was done through mean imputation and Min–Max normalization as a strategy to address missing values and standardized features. The five supervised models, consisting of Logistic Regression (LR), Support Vector Machine (SVM), K-Nearest Neighbors (KNN), Random Forest (RF), and Gradient Boosting (GB), were explored and evaluated. The experimental results showed that GB was the finest, attaining an accuracy of 86%, significantly more than other models, and better than previously claimed. This machine learning framework set forth will be beneficial for automated and data-driven water quality monitoring. However, the practical challenges of an imbalanced dataset and not using any microbiological characteristics were recognized and would be planned for in future work by conducting further experimentation on expanded dataset sample sizes and evolving to hybrid models with complex features.

Renugadevi, Maridu Bhargavi, Shaik Abdul Afzal Biyabani Adopting Artificial Intelligence Tools in Higher Education Student Assessment, 2025 The chapter delves into the transformative impact of artificial intelligence (AI) on educational assessments, highlighting how AI significantly enhances accuracy, efficiency, and personalization compared with traditional methods. By analyzing vast datasets, AI provides deeper insights into student performance, allowing for personalized learning experiences tailored to individual needs. One of its key advantages is delivering real-time feedback, which facilitates immediate corrections, reinforces learning, and ultimately improves student understanding and retention. AI also ensures consistent and unbiased evaluations by applying predefined criteria, thus minimizing human biases and promoting fairness. Its role is crucial in both formative and summative assessments. In formative assessments, AI tracks student progress over time, offering continuous feedback that helps educators adjust their teaching strategies as needed. However, the integration of AI into educational assessments comes with challenges, including concerns about data privacy, algorithm transparency, and potential biases within the systems. Addressing these issues is vital for the ethical and effective use of AI in education. Despite these challenges, AI-driven assessment techniques hold the potential to revolutionize the way student evaluations are conducted, making them more accurate, efficient, personalized, and fair.

This paper applies several machine learning techniques to analyze and predict variations in temperature, using a global dataset containing average temperature and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\text{CO}_{2}$</tex> emissions. The preprocessing of data included feature engineering, normalization, and classification of temperature levels into two classes. Several models were developed and compared: Decision Tree, Naïve Bayes, Random Forest, Support Vector Machine, and XGBoost. The paper also applied ensemble methods like Stacking and Voting Classifiers to improve the accuracy of the predictions. The comparison indicated that, overall, the performance of the ensemble models in classifying high and low variations of temperatures was better compared to individual classifiers. As a whole, this study focuses on the fact that machine learning can be a strong tool for understanding the variation in climate change and predicting it, thus being of great help for environmental planning, policy framing, and sustainability studies.
AI for Finance: Hybrid Learning Models for Stock Prediction Padusuri SaiBabu, Maridu Bhargavi, Vemula Jayasri, Ganpisetty Pravallika, Uzma Afzal 2025 IEEE International Conference on Emerging Trends in Computing and Communication Etcom 2025, 2025 Stock price prediction remains one of the most challenging problems in financial analytics due to market volatility, nonlinear dependencies, and sensitivity to external economic factors. Accurate stock forecasting is essential for investors and financial institutions to make informed decisions, reduce risk, and maximize returns. Traditional econometric approaches, such as ARIMA, struggle to model the nonlinear and dynamic behavior of stock data, leading to increased interest in machine learning (ML) and deep learning (DL) techniques. This paper presents a hybrid framework that integrates Support Vector Regression (SVR), Random Forest Regression (RFR), and Long Short-Term Memory (LSTM) networks for stock price prediction. The methodology includes rigorous data preprocessing, feature extraction using technical indicators such as Moving Averages, RSI, MACD, Bollinger Bands, and OBV, followed by normalization for model stability. SVR and RFR serve as classical regression baselines, while LSTM captures temporal dependencies. An ensemble layer combines their predictions through weighted averaging optimized using validation performance. Experiments conducted using five years of S&P 500 daily historical data show that the LSTM model achieved an RMSE of 2.15 and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{R}^{\mathbf{2}}$</tex> of 0.91, outperforming the standalone ML models. The hybrid ensemble achieved further improvements with an RMSE of 1.92 and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{R}^{\mathbf{2}}$</tex> of 0.93, proving that hybridization enhances both robustness and predictive accuracy. The results confirm that deep learning effectively captures sequential dependencies, while ensemble methods provide resilience and generalization. Future work will incorporate sentiment analysis, macroeconomic indicators, and explainable AI (XAI) to improve interpretability and real-world adoption.
