Once-for-All Network
Definition
Once-for-All networks deliver suitable subnetworks for different hardware targets.
A supernet method that trains many subnetworks, from which specialized subnetworks can be selected for various hardware targets.
Simply explained
From a jointly trained large toolbox, a suitable smaller network is selected.
Why it matters in practice
Helps realistically assess model quality, limits, and technical decisions.
Example from business
From a trained supernet, a small subnetwork is chosen for a specific edge device.
Limits and pitfalls
- Treat OFA as arbitrarily portable or do not check search space, calibration, and target hardware.
Origin & history
Cai and co-authors published Once-for-All in 2019.
Use in mid-sized companies
- Possible example: From a trained supernet, a small subnetwork is chosen for a specific edge device.
