With two operations: adding vectors and multiplying by scalars, we can produce a linear combination of v and w: cv dw. The linear combination of u, v, and w will not expand further from the plane. Using Pythagoras formula, we can derive that the length of a vector v is the square root of v₁² v₂² …v𝚗², which happens to be the square root of v · v.

With one three-dimensional vector u, the combination cu fill a line through (0, 0, 0). The dot product between two vectors v and w is the number v · w = v₁w₁ v₂w₂ … Vectors with length 1 have a special name: a unit vector.

With the recent growth in undergraduate and master’s level programs in data science there is a need for textbooks and courses that cover the required mathematical background, particularly in applied linear algebra.

At MIT, Gilbert Strang has developed and taught one such course, 18.065, at the advanced undergraduate/graduate level.

These are topics that an undergraduate student might not encounter in their course work and that are undeniably important in various areas of data science, but this book does not always connect these topics to their data science applications.

The author has tried to cram far too much material into the 432 pages of the book so each topic gets a very quick presentation.An instructor preparing to teach a course on mathematics for data science might find this book inspirational and useful as a source of topics, examples, and exercises.However, I expect that students would have a very difficult time with this book and I would not assign it to students as a course textbook.Gil Strang tells me that he began to think about linear algebra in terms of four fundamental subspaces in the 1970's when he wrote the first edition of his textbook, Introduction to Linear Algebra.The fifth edition, which was published last May, features the spaces on the cover. The Singular Value Decomposition provides a natural basis for Gil Strang's Four Fundamental Subspaces.Screen shot from Gil Strang MIT/Math Works video lecture, "The Big Picture of Linear Algebra".Introduction to Linear Algebra 5e editie is een boek van Gilbert Strang uitgegeven bij Wellesley-Cambridge Press, U. ISBN 9780980232776 Introduction to Linear Algebra is een boek van Gilbert Strang Levertijd We doen er alles aan om dit artikel op tijd te bezorgen.Het is echter in een enkel geval mogelijk dat door omstandigheden de bezorging vertraagd is.Video lectures and other course content is available through MIT’s Open Course Ware. Like his other textbooks, it is self-published by Strang’s Wellesley Cambridge Press.The topics discussed in this book could be extremely useful to any student getting started in data science and machine learning.
