Q: How does multi-task learning differ from single-task learning?

A: Single-task learning trains one model per objective. Multi-task learning trains one model on many objectives at once, letting gradients from each task update shared weights and thereby improve low-resource tasks with data from high-resource ones.

Q: When should you use multi-task learning?

A: Use it when you have several related prediction problems and limited labeled data for some of them; the shared representation can raise accuracy on all tasks while cutting total parameter count.

Q: Does multi-task learning always improve performance?

A: No. If tasks are unrelated or optimization is imbalanced, gradients can conflict and degrade accuracy. Task weighting, architecture design, and gradient-surgery techniques mitigate negative transfer.
