Perhaps you should try some spelling variations:
convolutional algorithms » convolution algorithms, evolution algorithm, evolutionary algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
passive estimation » pose estimation
deep convolutional » d convolutional, graph convolutional
modified passive » modified adaptive
modified deep » modified delphi, modified df, modified near

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified passive estimation algorithms ) or ( modified deep convolutional algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified passive estimation algorithms ) OR ( modified deep convolutional algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified passive estimation algorithms ) or ( modified deep convolutional algorithms ))*.
