Perhaps you should try some spelling variations:
quantization algorithms » estimation algorithms, optimization algorithms
convolution algorithm » convolution algorithms, evolution algorithm, solution algorithm
passive quantization » adaptive quantization
modified passive » modified adaptive

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 quantization algorithms ) or ( machine learning convolution algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified passive quantization algorithms ) OR ( machine learning convolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified passive quantization algorithms ) or ( machine learning convolution algorithm ))*.
