The Good Samaritan Centre was located secluded in a green village. The clients housed in there seemed to live there against their will. Little did they know, they were there for their own safety and well-being! They kept trying and turning the door locks to escape without success! Outside the glass doors lay an open, beautiful garden designed and planted to offer solace, pleasure, and emotional therapy for the clients. Far away from the guarded doors, they scramble for research and to cure the precious lives from the devastating disease that took the priority on each country’s development agenda. In some countries, it was feared that senior citizens were at the edge of extinction. In other countries, it was a natural condition for the aged. Meanwhile, every sixty-seven seconds, a new case appeared. One of her church friends had just been diagnosed and admitted to hospital for the same disease! Justina felt she had a responsibility to contribute and help fight the menace! The responsibility every carer dreads!

A groundbreaking introduction to vectors, matrices, and least squares for engineering applications, offering a wealth of practical examples.

The fundamental mathematical tools needed to understand machine learning include linear algebra, analytic geometry, matrix decompositions, vector calculus, optimization, probability and statistics. These topics are traditionally taught in disparate courses, making it hard for data science or computer science students, or professionals, to efficiently learn the mathematics. This self-contained textbook bridges the gap between mathematical and machine learning texts, introducing the mathematical concepts with a minimum of prerequisites. It uses these concepts to derive four central machine learning methods: linear regression, principal component analysis, Gaussian mixture models and support vector machines. For students and others with a mathematical background, these derivations provide a starting point to machine learning texts. For those learning the mathematics for the first time, the methods help build intuition and practical experience with applying mathematical concepts. Every chapter includes worked examples and exercises to test understanding. Programming tutorials are offered on the book's web site.
