Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
based learnings » based learning
learnings from » learning from, weaning from
from algorithm » mom algorithm, adam algorithm

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( based learnings from algorithm ) or ( modified parameter optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( based learnings from algorithm ) OR ( modified parameter optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( based learnings from algorithm ) or ( modified parameter optimisation algorithm ))*.
