Unsupervised Learning - Kmeans Week 11 Challenge

Answer 1

We use certain similarity metrics to determine if two objects are alike

The similarity is a value that ranges between 0 and 1

The simplest way to find similarity between two categorical attributes is to assign a similarity of 1 if the values are identical and similarity of 0 if the values are not identical.

Some of the similarity measures are as follows

1. Euclidian distance

2. Manhattan distance

3. Cosine similarity
