Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a scenario where you notice that your model is converging very slowly when using Batch Gradient Descent. Discuss potential reasons and solutions.

💡 Hint: Analyze the balance between speed and stability.

Challenge 2 Hard

Imagine you are working with a dataset featuring significant outliers. How might Stochastic Gradient Descent behave differently with this data compared to Batch Gradient Descent?

💡 Hint: Think about the impact of observing the full dataset vs. isolated samples.
