- What does hard parameter sharing mean?
- Each task has a separate full network with a similarity penalty
- Tasks share labels but no model parameters
- One output head predicts every task without task identity
- Tasks share a common hidden trunk and use task-specific output heads
- How does hard sharing differ from soft parameter sharing?
- Soft sharing keeps separate task parameters and encourages them to remain similar
- Soft sharing always uses one shared trunk
- Hard sharing stores no parameters
- The two terms mean the same architecture
- Why can hard sharing reduce overfitting for related tasks?
- Each task receives more independent parameters
- Shared layers learn features that must serve multiple tasks
- The model avoids training data
- All tasks are forced to use identical output labels
- How are task losses commonly combined for joint training?
- By choosing one task and ignoring the others
- By averaging labels across tasks
- As a weighted sum in a shared objective
- By using only the smallest loss
- What can happen if one task’s loss or gradients dominate?
- All task heads disappear
- The tasks become independent
- The model automatically balances every gradient
- The shared trunk may prioritize it while other tasks are under-served
- When is hard parameter sharing most suitable?
- When tasks can benefit from useful shared representations
- When every task is unrelated and incompatible
- When a task must never influence another
- When there is only one task
- What does a task-specific head usually do?
- Stores all training examples
- Maps shared features to that task’s output
- Balances the gradients of every other task
- Selects which hidden trunk to use per token
- What should be monitored when training a multi-task model?
- Only the total parameter count
- Only the largest task’s accuracy
- Per-task performance and whether shared updates help or harm each task
- The number of output heads alone
