Description
Hidden Markov Models and AI: Sequential Data, Speech Recognition & NLP Applications (Vol. 3)
Author: Anshuman Mishra
Artificial Intelligence continues to evolve toward systems capable of understanding, predicting, and acting within highly dynamic environments. While deep learning has transformed many areas of AI, probabilistic sequence models—especially Hidden Markov Models (HMMs)—remain indispensable in domains where interpretability, sequential reasoning, uncertainty modeling, and statistical efficiency are essential.
Hidden Markov Models and AI: Sequential Data, Speech Recognition & NLP Applications (Vol. 3) is the final volume of this comprehensive series and takes readers beyond theory into practical implementation, interdisciplinary applications, industrial case studies, and future research frontiers. Building upon the mathematical foundations introduced in Volume 1 and the speech recognition and natural language processing applications explored in Volume 2, this volume demonstrates how Hidden Markov Models continue to power intelligent systems across bioinformatics, finance, cybersecurity, Internet of Things (IoT), robotics, autonomous navigation, and modern AI research.
Designed for undergraduate and postgraduate students, AI researchers, software engineers, data scientists, computational biologists, robotics developers, and industry professionals, this volume combines rigorous theoretical concepts with hands-on programming, practical projects, and modern AI development frameworks.
Purpose and Vision of the Book
The goal of this volume is to help readers transition from understanding Hidden Markov Models to confidently implementing and applying them in real-world AI systems.
The book is guided by five core principles:
- Demonstrate practical implementation of HMMs.
- Explore interdisciplinary AI applications.
- Connect classical probabilistic models with modern deep learning.
- Provide industry-oriented projects and case studies.
- Inspire future research in probabilistic Artificial Intelligence.
Rather than treating HMMs as historical algorithms, this book presents them as living technologies that continue to contribute to modern intelligent systems.
