Question 1

What is soft clustering?

A method of group assignment where each point belongs to one cluster.
A method allowing each data point to belong to multiple clusters with varying probabilities.
A clustering technique that requires linear separability.

💡 Hint: Think about cases where data points may fit more than one category.

Question 2

True or False: Gaussian Mixture Models can only model unimodal distributions.

True
False

💡 Hint: Consider what happens when data has multiple peaks.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If you are tasked with using GMMs to segment customers, describe your approach to determining the appropriate number of components (clusters) to use.

💡 Hint: Understanding these criteria is crucial for deciding how many clusters best fit the data.

Challenge 2 Hard

Discuss the implications of local maxima in GMM parameter estimation and how it can impact model quality.

💡 Hint: Consider how using different starting points can change the outcome of clustering.
