  3. 3 Hard

    What does high bias in a model usually cause?

    Answer: Underfitting

    Why: Its mirror image is high variance, which makes a model chase random noise in its training data and overfit.

    What does DeepMind's AlphaFold predict?

    Answer: Protein shapes

    Why: Demis Hassabis and John Jumper shared half of the 2024 Nobel Prize in Chemistry for this protein work.

  5. 5 Medium

    Which setting controls how far weights move on each update?

    Answer: Learning rate

    Why: Set it too high and training jumps right over the best weights; set it too low and learning crawls.

  6. 6 Hard

    Which hypothesis says big networks hide small ones that train as well?

    Answer: Lottery ticket hypothesis
