estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
response estimation » response optimization, pose estimation, response association
qoe estimation » pose estimation, _ estimation, cover estimations

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( qoe estimation algorithmss ) OR ( response estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( qoe estimation algorithmss ) or ( response estimation algorithms ))*.
