This research proposes an advanced ensemble model based on Convolutional Neural Networks (CNNs) designed to enhance the segmentation and classification of skin lesions, a critical step in the early detection of melanoma and other skin cancers. The study explores ensemble strategies, including bagging, boosting, and stacking, to identify the most effective approach for combining multiple CNN models. A novel ensemble method incorporating pre-trained dual encoders is introduced to improve segmentation accuracy by extracting critical features and precisely delineating lesion boundaries. The dual encoders are configured with different encoder-decoder architectures, activation functions, and optimization algorithms to optimize feature extraction and segmentation performance. The suggested model was tested on the ISIC 2019 and HAM10000 datasets, attaining an accuracy rate of 95.3%, with sensitivity at 93.7%, specificity at 96.8%, and an F1-score of 94.5%. The findings demonstrate a significant improvement over current leading techniques, confirming the robustness and reliability of the proposed ensemble strategy. The superior performance of the model suggests its potential for integration into clinical practice, providing dermatologists with a valuable tool for early skin cancer detection and improving patient outcomes through timely intervention. © 2024 IEEE.

One of the most challenging jobs in image processing techniques is image segmentation. To identify the objects of interest in an image, we segment the image into different parts and extract the interesting objects. Previous studies have addressed various techniques for image segmentation, like clustering, thresholding, watershed, neural networks, etc. However, a segmentation technique alone cannot achieve better-segmented results. Much research is being carried out by combining the segmentation technique with either an optimization algorithm or entropy measures to enhance the efficiency of segmented results in the segmentation process. So, there is a need to study various segmentation techniques combined with optimization algorithms or entropy measures. Recent studies focused only on segmentation techniques, entropy measures, or optimization algorithms rather than on these combinations. This paper presents various works based on optimization techniques and entropy measures combined with clustering and thresholding techniques of image segmentation. From the study it is observed that most of the work is carried out in combining thresholding-based image segmentation techniques with optimization algorithms and entropy measures. © 2024 Bharati Vidyapeeth, New Delhi.

Precision agriculture uses cutting-edge technology to improve farming operations, increase crop yields, and reduce resource use. This study focuses on developing an autonomous weed and crop detection system that leverages the cutting-edge You Only Look Once (YOLO) *** purpose is to equip farmers with a real-time solution to identify and distinguish crops fromweeds in agricultural fields. The process entails creating a well-annotated dataset with photos of both crops and weeds. A pre- trained YOLO model, such as YOLOv3 or YOLOv4, is chosen and fine-tuned with the annotated dataset. The YOLO configuration file is changed to meet the unique crop and weed detection needs. The training procedure continues until adequate convergence is obtained. The trained YOLO model is then connectedwith agricultural equipment, such as drone-mounted cameras or other sensing devices, allowing for real- time detection in the field. Post-processing techniques are used to improve detection results while minimizing false positives. Decision-making algorithms are developed to direct activities based on the detected crops and weeds, allowing for focused interventions such as precision herbicide administration. © 2024 IEEE.

Suspect identification can be challenging for forensic investigations since standard procedures are time-consuming and prone to mistakes. This calls for the creation of novel approaches utilizing developments in machine learning (ML) and artificial intelligence (AI). In order to overcome these obstacles, the proposed Face Generation and Recognition in Forensic science will make use of sophisticated recognition algorithms and AI-based face generation models. Fully trained Stable Diffusion model is applied to generate high-quality face images from textual descriptions. Image Generation, Text Guided Image Manipulation using Denoising Diffusion Probabilistic Models (DDPMs), and Dataset Matching are the three primary components of the process. Using a stable diffusion model, Image Generation quickly creates high-resolution images from word prompts by combining an autoencoder (VAE), U-Net, and text encoder. With the introduction of an alternate noise space for DDPMs, Text Guided picture Manipulation makes it possible to do meaningful picture altering tasks in response to text prompts. VGG-16 , a convolutional neural network architecture is used in dataset matching to extract features and calculate similarity, which makes dataset alignment and comparison easier. The suggested methodology gives law enforcement authorities effective tools for identifying suspects, which represents a substantial development in forensic investigations. The project intends to increase the efficiency of criminal investigations, accelerate the matching process with large datasets, and enhance the accuracy of facial sketches by utilizing AI and ML approaches. The approach's ability to produce coherent and contextually relevant face images is validated by experimental results, which also show the approach's potential for speeding up the conclusion of criminal cases, particularly unsolved cold cases. All things considered, Face Generation and Recognition in Forensic science is a promising step in st

In the field of medical image analysis, the integration of machine learning (ML) models has significantly enhanced the process of identifying and diagnosing Alzheimer's disease. However, the opacity of these models, often termed as "black boxes,"raises concerns regarding their interpretability and reliability in clinical settings. Explainable artificial intelligence (XAI) techniques have emerged as crucial tools to address these challenges by clarifying the reasoning behind model outputs. This paper offers an extensive review of literature concerning the employment of Explainable Artificial Intelligence (XAI) methodologies, such as SHAP, LIME, GradCAM, DeepLIFT, Saliency Maps, and LRP to augment the comprehensibility of ML models applied in the detection of Alzheimer's disease. © 2024 IEEE.

An extensive use case of Generative Adversarial Networks (GANs) that not only combines artistic creativity with technological innovation but also significantly improves identification precision, filling in critical gaps in the smooth integration of textual descriptions with visual representations. The motivation is rooted on the difficulties that currently exist in accurately identifying human face sketches by directly transforming them into images, an area where prior approaches were inadequate. Our special dual-function technology is designed to get beyond these obstacles and provides a fresh approach for forensic investigators, artists, and sculptors. It has the ability to convert text to image as well as sketch to image. This easy transformation of textual and drawing data represents an integrated combination of creativity and technology that is set to have an impact on a number of disciplines, such as suspect identification and crime scene reconstruction. © 2024 IEEE.

The The accurate forecasting of stock prices holds significant importance in devising effective trading strategies and making informed decisions about stock transactions. The inherent volatility in stock prices, driven by factors like geopolitical tensions, corporate earnings, and commodity costs, underscores the need for precise predictions. Domestic factors such as central bank policies, governmental decisions, inflation, and global market uncertainties also trigger stock price fluctuations. Estimating this volatility is a complex challenge for traders. A novel approach is presented in this research, proposing a hybrid model that integrates two distinct algorithms - Long Short-Term Memory-Convolutional Neural Network (LSTM-CNN). This model harnesses diverse data representations from stock time series to enhance price prediction accuracy. Comparative analyses are performed with alternative models like LSTM (Long Short-Term Memory), CNN (Convolutional Neural Networks) and Naïve Bayes to ascertain the most effective prediction paradigm with minimal error. The study demonstrates that combining temporal and image features extracted from the same dataset diminishes prediction errors compared to using these features independently. The hybrid model outperforms singular prediction models, highlighting a high enhancement. Among the individual models, the LSTM model exhibits superior performance in terms of prediction accuracy. © 2024 IEEE.

The widespread deployment of deep nets in practical applications has lead to a growing desire to understand how and why such black-box methods perform prediction. Much work has focused on understanding what part of the input pattern (an image, say) is responsible for a particular class being predicted, and how the input may be manipulated to predict a different class. We focus instead on understanding what internal features computed by the neural net are responsible for a particular class. We achieve this by mimicking part of the net with a decision tree having sparse weight vectors at the nodes. We are able to learn trees that are both highly accurate and interpretable, so they can provide insights into the deep net black box. Further, we show we can easily manipulate the neural net features in order to make the net predict, or not predict, a given class, thus showing that it is possible to carry out adversarial attacks at the level of the features. We demonstrate this robustly in MNIST and ImageNet with LeNet5 and VGG networks. © 2024 Copyright for this paper by its authors.

Federated Learning facilitates the collaborative training of a deep learning model by leveraging the combined data of multiple entities, with a focus on maintaining the privacy of individual datasets. The Sparse Ternary Compression (STC) method improves gradient sparsification by integrating downstream compression, ternarization, and optimal Golomb encoding of weight updates. Although STC enhances compression techniques in federated learning, the broader scope of Federated Learning lies within the domain of machine learning. Researchers investigating improvements in STC compression techniques must consider neural network concepts and the impact of hyperparameters, such as learning rate, on convergence speed and accuracy. Increased communication across multiple devices poses challenges in achieving desired accuracy levels. Our research underscores the importance of selecting appropriate learning rate schedules when implementing algorithms like STC. Incorrect choice of learning rate schedules can hinder convergence, even if the algorithm functions effectively, emphasizing the crucial role of hyperparameters in reducing communication costs and achieving desired accuracy levels © 2024 IEEE.
