This Book Is The Third Volume In The New Era Electronics Lecture Notes Series, A Compilation Of Volumes Defining The Important Concepts Tied To The Electronics Transition Happening In The 21st Century.the Material Is Adapted From A Unique Course That Connects Three Diverse Fields - Statistical Mechanics, Neural Networks And Quantum Computing - Using The Unifying Concept Of A State-space With 2ndimensions Defined By N Binary Bits. First, The Seminal Concepts Of Statistical Mechanics, Developed To Describe Natural Interacting Systems, Are Described. Then, These Concepts Are Connected To Engineered Interacting Systems Like Boltzmann Machines (bm), Which Are Cleverly Designed To Solve Problems In Machine Learning.
