What advantage do neural networks hold over plain word counting?
- They memorize exact sequences perfectly
- They learn patterns that cover unseen sentences
- They skip training data entirely
Where does the supervision signal for next-word guessing come from?
- The text itself, which shows what comes next
- Human labels on every sentence
- A teacher correcting each guess live
Low held-out loss guarantees that the model's answers are true.
Circle one: True False
Where does the free-supervision advantage stop?
- At user intent, which text patterns do not encode
- At rare words, which need extra counting
- At long books, which exceed memory
A model trained only to guess next words handles new grammar well. Why?
- Grammar rules were labeled by hand first
- The test sentences sat inside the training set
- Good compression of text keeps grammatical patterns
Two models post the same low held-out loss, but one answers users far better. What best explains the split?
- The worse model must have seen less text
- Loss measures guessing skill, while user fit needs something extra
- Loss values below a threshold stop meaning anything
A critic says next-word training cannot yield any task ability at all. Which fact answers them?
- One objective over enough text forces grammar, facts, and rough task sense along the way
- Models memorize every training sentence word for word
- Human labelers secretly grade each position
A team claims their model follows instructions because pretraining loss is low. What is the flaw?
- Loss is computed too slowly to matter
- Pretraining never touches instruction-style text
- Low loss rewards likely words, not obedience to intent
