Challenge Problems
Push your limits with advanced challenges
Suppose you have a mixture model for customer segmentation, and the E-step estimates that a particular data point has a 60% probability of belonging to segment A and 40% to segment B. Discuss how you would weigh this data point during model training.
💡 Hint: Focus on soft assignments and their impact on parameter updates.
Imagine you run a study with latent variables representing student engagement levels and only have their grades. Describe how the E-step can be implemented in this scenario.
💡 Hint: Consider the relationship between actions (grades) and inferred states (engagement).
