Perhaps you should try some spelling variations:
"using computational sparse coding program" » "using computational parser coding program" (Expand search), "using computation sparse coding program" (Expand search), "using computational search coding program" (Expand search), "and computational sparse coding program" (Expand search), "using computational sparse cloning program" (Expand search), "using computational sparse loading program" (Expand search), "using computational sparse cooling programs" (Expand search)
"based imputation in coding program" » "based computation in coding program" (Expand search), "based reputation in coding program" (Expand search), "based mutation in coding program" (Expand search), "based imputation in cloning program" (Expand search), "based imputation in loading program" (Expand search), "based imputation in cooling programs" (Expand search), "based imputation of coding program" (Expand search), "based implantation in coding program" (Expand search), "based imputation on coding program" (Expand search), "based imputation in decoding program" (Expand search), "based imputation non coding program" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based imputation in coding program\") OR (\"using computational sparse coding program\"))~".
• Removing quotes may allow a broader search: (( based imputation in coding program ) OR ( using computational sparse coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("based imputation in coding program") OR ("using computational sparse coding program"))*.
