Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Imagine you are designing a clustering model using a DPMM for categorizing types of artwork in a museum. Discuss how you would set the concentration parameter and what outcomes you expect.

💡 Hint: Consider the impact of your initial parameter settings on your clustering outcomes.

Challenge 2 Hard

Create a hypothetical dataset and describe how applying a DPMM will give you insights versus a traditional parametric clustering model.

💡 Hint: Reflect on how DPMMs more elegantly capture the complexity of real-world data.
