Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a scenario where you have an unbalanced dataset with significantly more images of one class. How would this affect model training and what strategies can mitigate these effects?

💡 Hint: Consider how the distribution of samples impacts learning.

Challenge 2 Hard

You mistakenly loaded your dataset without normalizing the pixel values. Explain the potential outcomes during training.

💡 Hint: Think about how varied inputs can cause instability in optimization.
