Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Imagine you have a dataset containing various fruits with features like weight, color, and sugar content. Design a preprocessing strategy for this dataset, considering any necessary transformations.

💡 Hint: Consider ways the data might need cleaning or unifying.

Challenge 2 Hard

You find that the dataset you are working with has significantly imbalanced classes. Propose a solution to preprocess and prepare this data for training a classification algorithm.

💡 Hint: Think about how to make classes more even before model training.
