In order to check similarity between 2 vectors, we can check the distance between them. There are a few different metrics to measure distance between 2 vectors.

import numpy as np

1. Cosine similarity

Measures the angle between 2 non-zero vectors. It ranges between $[-1, 1]$ $$cos (\theta) = \frac{\vec{p} \cdot \vec{q}}{||p|| \text{ } ||q||}$$

def cosine_similarity(p, q):
