The book Deep Learning & Applications, authored by Dr. A. Dennis Ananth, Dr. S. Markkandeyan, Dr. M. Rajakumaran, and Dr. B. Lakshmi, explores the foundational principles, advanced architectures, and diverse applications of deep learning in today’s technology-driven landscape. This comprehensive guide is structured to serve as a resource for both beginners and advanced practitioners in the field of artificial intelligence.

The book begins with an introduction to deep learning fundamentals, such as artificial neural networks, feedforward and convolutional neural networks, and recurrent neural networks. Key topics include training methodologies like backpropagation, optimization techniques, and popular gradient descent variants, all with illustrative examples and code snippets for hands-on learning.

In later chapters, the book delves into practical applications across various fields. For image processing, it covers techniques used in medical imaging, computer vision, and image segmentation. In natural language processing (NLP), topics such as transformers, BERT, and text classification are explored, along with applications in speech recognition and machine translation.

Further, it examines deep learning applications in finance and business, including stock market prediction and fraud detection. Advanced chapters address topics like explainable AI (XAI), transfer learning, deep reinforcement learning, and ethical considerations in AI. The book concludes with insights into emerging trends, such as quantum computing integration and AI at the edge.
