Computational Graphs

A computational graph shows the process of calculation. This graph is used as a graph of data structure and is represented by multiple nodes and edges (meaning, straight lines that connect nodes). In this section, we will solve easy problems to familiarize ourselves with computational graphs before advancing step by step into more complex backpropagation.

Using Computational Graphs to Solve Problems

The problems in this section are simple enough that you can solve them with mental arithmetic, but the purpose here is to get familiar with computational graphs. Learning to use computational graphs will be helpful for the complicated calculations we will cover later, so it's important to first master how to use them here.

Question 1: Taro bought 2 apples that were 100 yen apiece. Calculate the amount of money he paid if a 10% consumption tax was applied.

A computational graph shows the process of calculation with nodes and arrows. A node is represented...
