  • A deep learning model with inception vision transformer and harmonic fusion network for solar panel fault detection and classification
    Gangu Dharmaraju, Manoj Kumar Jena, Venkataramana Attada
    Computers and Electrical Engineering, 2026
    A solar panel is made up of silicon-based solar cells and uses the Photovoltaic (PV) effect to convert solar energy into electrical energy. The conventional fault detection models failed to identify the exact fault types, thereby requiring additional tools for classification. Thus, an innovative Inception Vision Transformer and Harmonic fusion Network (IncepViTH-Net) approach is developed for automated solar panel fault detection and classification. At first, the solar panel images are collected from a specific dataset. Then, sourced images are filtered by pixel brightness correction methodology. Later, the affected fault regions of solar panels are segmented by U-Net architecture. Moreover, features, like Convolutional Neural Network (CNN), histogram features, Angular Second Moment (ASM), and inverse difference moment are extracted for further analysis. Then, the solar panel fault detection and classification is executed by IncepViTH-Net model, which fuses strengths of Inception Version 3 Network (InceptionV3-Net), Vision Transformer (ViT), and harmonic analysis. The outcomes achieved by IncepViTH-Net are an accuracy of 96.988 %, True Positive Rate (TPR) of 97.988 %, and True Negative Rate (TNR) of 96.577 % for K Value 8.

    International Journal of Basic and Applied Sciences, 2025
    Skin cancer is the most common form of cancer globally. Timely detection is crucial, since failure to identify it in the first stage may result in ‎grave consequences. Notwithstanding its apparent visibility, significant intra-class heterogeneity and inter-class homogeneity complicate its ‎identification. Current AI methodologies for detecting skin cancer are hindered by their reliance on convolutional neural networks, resulting ‎in a lack of interpretability and sluggish processing speeds. To address the issue, the study proposes a comprehensive pipeline that integrates deep learning and machine learning methodologies to enhance detection accuracy in identifying skin lesions. The dataset under con-‎consideration is the International Skin Imaging Collaboration (ISIC) 2020. Initially, we pre-process the photos to guarantee precise training and ‎categorization. The EfficientNet-B7 deep learning model is employed for feature extraction and fed into a support vector machine ‎‎(SVM) classifier. The assessment of parameters such as accuracy, precision, recall, and F1 score yielded an accuracy of 97.52% and an F1 ‎score of 98.61%. The proposed model demonstrates superior results relative to other current models‎.
  • Image Based Multi Class Fault Detection in PV Systems using Deep Learning Model
    Gangu Dharmaraju, Manoj Kumar Jena, Attada Venkataramana
    2025 IEEE 7th International Conference on Computing Communication and Automation Iccca 2025, 2025
    Solar energy is one of the most environmentally friendly power sources that is the most sustainable, utilizing solar panel energy. The fault on solar panels reduces with loss in production efficiency. This proposed methodology observes multi class fault on the solar panel using a ViT model. Unlike the convolutional neural networks (CNN), such as R2CNN, vision transformers compute interconnections using the self-attention mechanism, which are long enough to capture the extended interconnections in the input images, and hence vision transformers are efficient for the fault identification and classification in solar panels. The construction of dataset with faults including snow cover, dust accumulation, physical damage, bird droppings and electrical damage is part of our methodology. Thus, the proposed model was trained and fine-tuned on this dataset and classifies the faults better than the conventional deep learning model with an accuracy of 98 %. We also improve false negatives and false positives in the evaluation and our approach improves accuracy.

    Solar energy is one of the most environmentally friendly energy sources that is the most sustainable, utilizing solar panel energy. The fault on solar panels attenuates with loss in production efficiency. This proposed methodology observes multi class fault on the solar panel using a ViT model. Unlike the convolutional neural networks (CNN), such as R2CNN, vision transformers compute interdependencies using the self-attention mechanism, which are long enough to capture the extended interdependencies in the input images, and hence vision transformers are efficient for the fault detection and classification in solar panels. The construction of such a large dataset of faults including dust accumulation, physical damage, snow cover, bird droppings and electrical damage is part of our methodology. Thus, the proposed model was trained and fine-tuned on this dataset and classifies the faults better than the conventional deep learning model with an accuracy of 98 %. We also improve false positives and false negatives in the evaluation and our approach improves accuracy.
  • A Hybrid Approach for Malicious URL Detection Using ML Classifiers and Graph Neural Networks

    2025 6th International Conference on Data Intelligence and Cognitive Informatics Icdici 2025, 2025
    Cyber threats such as phishing attacks often exploit malicious URLs to deceive users and compromise sensitive information. Traditional feature-based machine learning methods, while effective, may struggle to capture the intricate relationships among URL components. In this research, a hybrid framework is proposed combining Graph Neural Networks (GNN) and Random Forest Classifier (RFC) to detect malicious URLs with high accuracy. The methodology applies extensive text preprocessing to tokenize URLs into subdomains, domains, and path elements. For graph-based learning, each URL is converted into a token graph where nodes represent URL components and edges capture relational structures. Simultaneously, handcrafted features such as URL length, HTTPS presence, and special character counts are extracted for RFC training. The GNN model learns structural dependencies through graph convolution operations, while the RFC model leverages decision tree ensembles for robust feature-based classification. Experiments on a large-scale Kaggle phishing URL dataset demonstrate that both models achieve excellent detection performance, with RFC slightly outperforming GNN in precision and speed. The hybrid framework provides a scalable and effective solution for real-time phishing detection, combining the strengths of structural graph analysis and traditional machine learning.

    2024 2nd International Conference on Computer Communication and Control Ic4 2024, 2024
    Phishing attacks have become increasingly sophisticated, posing a significant threat to individuals and organizations. The ability to detect phishing websites is crucial for mitigating potential risks and safeguarding sensitive information. Traditional methods of detecting phishing websites often struggle to keep pace with the evolving tactics employed by cybercriminals. As a result, there is a pressing need for innovative and adaptive solutions to identify and combat this pervasive threat. This paper proposed an advanced phishing detection system by leveraging the power of machine learning ensemble algorithms. A dataset from Kaggle was collected. Initially, four ML classifiers namely Random /forest, Extra tree classifier, Gradient boosting classifier and logistic regression classifier applied for phishing website detection. Later ensemble of these four ML algorithms with different ensemble method is develop for phishing website detection. In ensemble, two types of ensemblesapproach namely stacking ensemble and voting ensemble applied. Experimental results showcased the potential of this ensemble approach to improve accuracy and adaptability in the prediction of phishing websites.

    2024 1st International Conference on Innovations in Communications Electrical and Computer Engineering Icicec 2024, 2024
    In the realm of text classification, particularly news classification, advanced deep learning models have demonstrated substantial potential for enhancing accuracy and performance. This paper investigates the application of several prominent deep learning architectures: CNNs, RNNs and Transformer-based BERT model. CNNs were employed to capture local patterns and hierarchical features within text data, contributing to effective categorization of news articles. RNNs, including LSTM networks, were utilized to model sequential dependencies and contextual relationships in news text, addressing the challenge of understanding temporal aspects. Additionally, Transformer-based models such as BERT (Bidirectional Encoder Representations from Transformers) were leveraged for their superior contextual and semantic comprehension, achieving notable performance improvements. The study provides a comprehensive analysis of these models' effectiveness, comparing their strengths and limitations based on accuracy results. BERT and its hybrid combinations, particularly with LSTM, achieved the highest accuracy. The paper highlights the most effective approaches for leveraging deep learning in text classification and offers insights into future research directions in this domain.
