Preface
The combination of intelligent data analytics with the intricacies of biological data has become a crucial factor for innovation and growth in the fast-changing field of bioinformatics and biomedical systems. At the convergence of biology, medicine, and computational science, there is an urgent need for advanced analytical methods to interpret biological data.
The book explores the complex field of biological data analysis. It offers a thorough examination of advanced techniques, methodologies, and applications that utilize intelligence to solve biological puzzles and improve healthcare results. The introduction of high-throughput technology has resulted in a large amount of biological data, which has presented both unique issues and opportunities. The field of biological information is rapidly expanding, encompassing genomics, proteomics, clinical data, and medical imaging. This growth provides a rich environment for computational methods to uncover hidden patterns, trends, and insights within the data.
Chapter 1 delves into the progress of machine learning algorithms for analyzing biological data. The convergence of machine learning and biological data analysis has ushered in a new era of scientific exploration. This chapter examines state-of-the-art machine learning methods used with different forms of biological data, emphasizing their contribution to understanding intricate biological processes. The fusion of artificial intelligence and biology demonstrates how these methods improve our comprehension of genomes, proteomics, metabolomics, and medical uses. By providing vivid examples, this section illustrates the potential of machine learning to revolutionize biological research by pushing its limits.
Chapter 2 examines the application of predictive analytics in clinical diagnosis, and its impact on customers, healthcare professionals, and the healthcare system. Predictive analytics utilizes information, statistical formulae, and artificial intelligence to forecast and analyze disease hazards. The initial stage involves delineating the data sources, preprocessing techniques, and predictive modeling approaches employed in healthcare predictive analytics. This book demonstrates the significance of predictive analytics in the diagnosis of ailments, evaluation of risks, and provision of personalized treatment recommendations through the use of compelling application examples. In addition to image analysis, the technology offers medical practitioners accurate insights through the interpretation of pictures, making it an essential analytical tool.
Chapter 3 classifies the various categories of skin diseases. The fields of dermatology and dermoscopy present distinct difficulties due to their intrinsic intricacy and the elevated level of proficiency necessary for precise diagnosis. To tackle these difficulties, this chapter suggests a computerized method that utilizes advanced techniques in deep learning and machine learning to diagnose skin problems based on images. The goal is to surpass the constraints of traditional diagnostic procedures by utilizing cutting-edge computational technologies.
To start, simpler approaches that combined conventional machine learning models with image processing techniques were analyzed. This entailed utilizing techniques such as Histogram of Oriented Gradients (HOG) and Fast Fourier Transform (FFT) to extract features, along with image augmentation methods. The collected features were subsequently employed to train different conventional machine learning models for the categorization of skin conditions. Next, the field of deep learning is explored with training conducted on models such as ResNet18, ResNet50, EfficientNet, and InceptionNet. Compared to human procedures, these deep learning models demonstrated superior accuracy and efficiency, indicating the promise of a more dependable and efficient diagnostic system.
Chapter 4 investigates computer-aided polyp detection via a tailored Convolutional Neural Network (CNN) architecture. Identifying polyp frames manually is a time-consuming task, especially for gastroenterologists who specialize in this area. Utilizing deep learning algorithms for the automatic detection of polyps can potentially optimize the efficiency of gastroenterologists by reducing the time required for diagnosis. This chapter presents an automated approach for polyp detection with a customized CNN architecture. The development process involved significant tweaking of several parameters, including optimizers, filter size, color space, image dimension, and kernel initializers. The efficacy of the suggested design was assessed using systematic ablation research, test set evaluation, and feature mapping. The system attained optimal outcomes with increased accuracy in polyp detection, together with decreases in execution time and number of trainable parameters.
Chapter 5 delves into the modern healthcare risks that stem from computational intelligence.
