Introduction

What does understanding language mean?

This “understanding” of text is mainly derived by transforming texts to useable computational representations, which are discrete or continuous combinatorial structures such as vectors or tensors, graphs and trees.

Computational Graphs

Technically, a computational graph is an abstraction that models mathematical expressions. Let’s see how the
computational graph models expressions. Consider the expression:
\[ \boldsymbol{y}=\boldsymbol{w} \boldsymbol{x}+\boldsymbol{b} \]

We can then represent the original expression using a directed acyclic graph (DAG) in which
the nodes are the mathematical operations, like multiplication and addition.
