Mathematical Foundations of AI and Data Science

Discrete Structures, Graphs, Logic, and Combinatorics in Practice

Author: Anshuman Mishra

Artificial Intelligence and Data Science are often presented as fields dominated by programming, algorithms, and machine learning frameworks. However, behind every intelligent system lies a powerful mathematical foundation.

Mathematical Foundations of AI and Data Science: Discrete Structures, Graphs, Logic, and Combinatorics in Practice is designed to build that foundation.

The book brings together the essential concepts of Discrete Mathematics, Mathematical Logic, Set Theory, Relations, Functions, Combinatorics, Probability, Graph Theory, Algebraic Structures, Boolean Algebra, Recurrence Relations, Optimization, Machine Learning, and Data Science in one integrated learning resource.

Its central objective is simple:

To connect mathematical concepts with the computational problems they help solve.

Instead of treating mathematics as a collection of isolated formulas, the book demonstrates how discrete structures become the foundation of algorithms, data structures, AI models, knowledge representation, networks, security systems, and data-driven applications.

Why Discrete Mathematics Matters in AI and Data Science

Modern computing is fundamentally discrete.

Digital information is represented using discrete units. Algorithms execute through sequences of discrete operations. Computer networks consist of nodes and connections. Logical systems operate through propositions and truth values. Databases manipulate collections of records, while many AI systems reason about relationships between entities.

The book therefore establishes discrete mathematics as an essential language for understanding computational systems.

Readers learn not only what a mathematical concept means, but also why it matters in Computer Science, AI, and Data Science.

The manuscript specifically connects concepts such as logic, sets, graphs, and combinatorics with algorithms, machine learning, big data, and intelligent systems.
