TheL¹ normis simply the sum of all the elements of the vector.It is used in machine learning when the system requires much more precision.To differentiate clearly between a zero and a non zero element. The L¹ norm is also known asManhattan norm. There is alsomax norm,which is th...

You're simply keen to understand the essentials of linear algebra, calculus, probability, stats, algorithms and/or data structures The foundational subjects have largely been unchanged in recent decades and are likely to remain so for the coming decades, yet they're critical across all machine lea...
It’s not a course in which facts are simply given and applied. It’s also not a course in “the art of proof” in that we tend to focus on the aspects of Linear Algebra that arise in many other contexts - applied and otherwise. Note regarding submission of homework: We REALLY ...
Did you know that “tensor” is a term taken directly from the field of linear algebra and it simply means an array with more than two-dimensions?Why Is Linear Algebra Important to Machine Learning?So, why is linear algebra used so much to describe machine learning algorithms?
In the study of linear algebra, the properties of linear functions are extensively studied and made rigorous. Given a scalar C and two vectors A and B from RN, the most general definition of a linear function states that:c×f(A+B)=c×f(A)+c×f(B)c \times f(A +B) = c \times...
