The magic square can be a magic stacked parallelogram and the corner numbers of these 16 parallelograms, as do the 4 numbers in each of the four vertical lines. The parallelogram can be mapped from the order-4 pantriagonal magic square. You have some numbers and you have to fill all missing numbers.

Granddaddy Parallelogram and his grandchildren, Rect the Rectangle and Rhombella the Rhombus, live in the land of quadrilaterals. It is an exciting place to be, but Rect and Rhombella have difficulty accepting each others differences. As a result, Rect and Rhombella dispute continuously. Their disagreements cease with self-discovery and a secret from their astute grandfather, Granddaddy Parallelogram. With vibrant color illustrations and accompanying stories children can relate to, the Granddaddy Parallelogram series is a useful tool to teach children advance geometric concepts initially. Children will enjoy entering the land of quadrilaterals and the engaging activities offered to parents and teachers to enhance their childrens knowledge. Experience gratification in math and adventures with the entire Granddaddy Parallelogram series.

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.

A compendium of over 5,000 problems with subject, keyword, author and citation indexes.
