Matrix multiplication. How to multiply matrices. In this video I show you how we define the multiplication of matrices. As you will see, it is not so simply as multiplying two numbers. Matrices can only be multiplied when the number of columns in the first matrix is similar to the numb

Moduli of Representations and Pseudorepresentations - Carl Wang Erickson
Carl Wang Erickson Harvard University May 2, 2013 A continuous representation of a profinite group induces a continuous pseudorepresentation, where a pseudorepresentation is the data of the characteristic polynomial coefficients. We discuss the geometry of the resulting map from the moduli

The Moore-Penrose Pseudoinverse — Topic 37 of Machine Learning Foundations
This video introduces Moore-Penrose pseudoinversion, a linear algebra concept that enables us to invert non-square matrices. The pseudoinverse is a critical machine learning concept because it solves for unknown variables within the non-square systems of equations that are common in machin

Matrix Multiplication Derivation
Have you ever wondered why matrix multiplication is so awkward? It turns out that if you think of matrices in terms of linear transformations then the definition becomes quite natural! Namely, matrix multiplication just becomes composition of linear transformations, which gives a much easi

Two counterexamples arising from infinite sequences of flops - John Lesieutre
John Lesieutre Member, School of Mathematics October 7, 2014 I will explain how infinite sequences of flops give rise to some interesting phenomena: first, an infinite set of smooth projective varieties that have equivalent derived categories but are not isomorphic; second, a pseudoeffect

Mathematics for Machine Learning: Matrix Multiplication and (Pseudo) Inverse With NumPy
In this video, we discuss linear algebra routines and matrix multiplications for 2D NumPy arrays, essential for understanding a wide range of machine learning and data science. We use several examples in Python to understand how matrix multiplication works. When analyzing large matrices (i

Regression with the Pseudoinverse — Topic 38 of Machine Learning Foundations
This is one of my favorite videos in the entire Machine Learning Foundations series! In it, we use Moore-Penrose pseudoinversion to solve for unknowns, enabling us to fit a line to points with linear algebra alone. When I first learned how to do this, it blew my mind -- I hope it blows you
