estimation algorithmss » estimation algorithm, optimization algorithms
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
adaptive estimation » adaptive ventilation, quantile estimation, adaptive quantization
modified adaptive » modified passive
qoe estimation » pose estimation, _ estimation, cover estimations
modified qoe » modified male, modified _, modified bi1

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: (( modified adaptive estimation algorithmss ) OR ( modified qoe estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive estimation algorithmss ) or ( modified qoe estimation algorithms ))*.
