At first glance, the definition for the product of two matrices can be unintuitive. In this post, we discuss three perspectives for viewing matrix multiplication. It is the third perspective that gives this “unintuitive” definition its power: that matrix multiplication represents the composition of linear transformations.| Matthew N. Bernstein
Graphs are ubiqitous mathematical objects that describe a set of relationships between entities; however, they are challenging to model with traditional machine learning methods, which require that the input be represented as vectors. In this post, we will discuss graph convolutional networks (GCNs): a class of neural network designed to operate on graphs. We will discuss the intution behind the GCN and how it is similar and different to the convolutional neural network (CNN) used in computer...| Matthew N. Bernstein
