[All Databricks-Certified-Professional-Data-Scientist Questions]

You are working in a data analytics company as a data scientist, you have been given a set of various types of Pizzas available across various premium food centers in a country. This data is given as numeric values like Calorie. Size, and Sale per day etc. You need to group all the pizzas with the similar properties, which of the following technique you would be using for that?

AAssociation Rules

BNaive Bayes Classifier

CK-means Clustering

DLinear Regression

EGrouping
Using K means clustering you can create group of objects based on their properties. Where K is number of the groups. In this case, in each group you determine the center of the group and then find the how far each object characteristics from the center. If it is near the center than it can be part of the group. Suppose we have 100 objects and we need to determine 4 groups. Hence, here K=4. Now we determine 4 center values and based on that center value we determine the distance of each object from the center.

I bet the person who came up with 'Grouping' as an answer was just really hungry and wanted to eat all the pizzas.

Haha, linear regression? For grouping pizzas? I'd like to see how that's supposed to work. K-means is the obvious answer.

Wait, why would you use a Naive Bayes classifier for this? That's more for classification, not grouping. K-means is the clear choice.
