Coding exercise

In this section, we will explore a basic one-shot learning approach. As humans, we have a hierarchical way of thinking. For example, if we see something unknown to us, we look for its similarity to objects we already know. Similarly, in this exercise, we will use a nonparametric kNN approach to find classes. We will also compare its performance to the basic neural network architecture.

kNN – basic one-shot learning

In this exercise, we will compare kNN to neural networks where we have a small dataset. We will be using the iris dataset imported from the scikit-learn library.

To begin, we will first discuss the basics of kNN. The kNN classifier is a nonparametric classifier that simply stores the training...
