The kingdom Animalia encompasses multicellular, eukaryotic organisms known as animals. Currently, there are approximately 1.5 million identified species of living animals, including over 195 distinct breeds of dogs. Each breed possesses unique characteristics that can be challenging to distinguish. Each breed has its own characteristics that are difficult to identify. Various computer-based methods, including machine learning, deep learning, transfer learning, and robotics, are employed to identify dog breeds, focusing mainly on image or voice data. Voice-based techniques often face challenges such as noise, distortion, and changes in frequency or pitch, which can impair the model’s performance. Conversely, image-based methods may fail when dealing with blurred images, which can result from poor camera quality or photos taken from a distance. This research presents a hybrid model combining voice and image data for dog breed identification. The proposed method Contrastive Language-Image Pre-Training-Audio Stacked Network (CLIP-ASN) improves robustness, compensating when one data type is compromised by noise or poor quality. By integrating diverse data types, the model can more effectively identify unique breed characteristics, making it superior to methods relying on a single data type. The key steps of the proposed model are data collection, feature extraction based on Contrastive Language Image for image-based feature extraction and Audio stacked-based voice features extraction, co-attention-based classification, and federated learning-based training and distribution. From the experimental evaluation, it has been concluded that the performance of the proposed work in terms of accuracy 89.75% and is far better than the existing benchmark methods.

Crime hotspot detection is essential for law enforcement agencies to allocate resources effectively, predict potential criminal activities, and ensure public safety. Traditional methods of crime analysis often rely on manual, time-consuming processes that may overlook intricate patterns and correlations within the data. While some existing machine learning models have improved the efficiency and accuracy of crime prediction, they often face limitations such as overfitting, imbalanced datasets, and inadequate handling of spatiotemporal dynamics. This research proposes an advanced machine learning framework, CHART (Crime Hotspot Analysis and Real-time Tracking), designed to overcome these challenges. The proposed methodology begins with comprehensive data collection from the police database. The dataset includes detailed attributes such as crime type, location, time and demographic information. The key steps in the proposed framework include: Data Preprocessing, Feature Engineering that leveraging domain-specific knowledge to extract and transform relevant features. Heat Map Generation that employs Kernel Density Estimation (KDE) to create visual representations of crime density, highlighting hotspots through smooth data point distributions and Hotspot Detection based on Random Forest-based to predict crime likelihood in various areas. The Experimental evaluation demonstrated that CHART shows superior performance over benchmark methods, significantly improving crime detection accuracy by getting 95.24% for crime detection-I (CD-I), 96.12% for crime detection-II (CD-II) and 94.68% for crime detection-III (CD-III), respectively. By designing the application with integrating sophisticated preprocessing techniques, balanced data representation, and advanced feature engineering, the proposed model provides a reliable and practical tool for real-world crime analysis. Visualization of crime hotspots enables law enforcement agencies to strategize effectively, focusing resources on high-risk areas and thereby enhancing overall crime prevention and response efforts.

Heart disease remains a leading cause of morbidity and mortality worldwide, highlighting the need for improved diagnostic methods. Traditional diagnostics face limitations such as reliance on single-modality data and vulnerability to apparatus faults, which can reduce accuracy, especially with poor-quality images. Additionally, these methods often require significant time and expertise, making them less accessible in resource-limited settings. Emerging technologies like artificial intelligence and machine learning offer promising solutions by integrating multi-modality data and enhancing diagnostic precision, ultimately improving patient outcomes and reducing healthcare costs. This study introduces Heart-Net, a multi-modal deep learning framework designed to enhance heart disease diagnosis by integrating data from Cardiac Magnetic Resonance Imaging (MRI) and Electrocardiogram (ECG). Heart-Net uses a 3D U-Net for MRI analysis and a Temporal Convolutional Graph Neural Network (TCGN) for ECG feature extraction, combining these through an attention mechanism to emphasize relevant features. Classification is performed using Optimized TCGN. This approach improves early detection, reduces diagnostic errors, and supports personalized risk assessments and continuous health monitoring. The proposed approach results show that Heart-Net significantly outperforms traditional single-modality models, achieving accuracies of 92.56% for Heartnet Dataset Ⅰ (HNET-DSⅠ), 93.45% for Heartnet Dataset Ⅱ (HNET-DSⅡ), and 91.89% for Heartnet Dataset Ⅲ (HNET-DSⅢ), mitigating the impact of apparatus faults and image quality issues. These findings underscore the potential of Heart-Net to revolutionize heart disease diagnostics and improve clinical outcomes.
