Perhaps you should try some spelling variations:
"using compositional data mining program" » "using computational data mining program" (Expand search), "in compositional data mining program" (Expand search), "music compositional data mining program" (Expand search), "using compositional data singing program" (Expand search), "using compositional data living program" (Expand search), "using compositional data hiring program" (Expand search)
"using convolutional data coding program" » "using convolutional and coding program" (Expand search), "using convolutional lstm coding program" (Expand search), "using convolutional bag coding program" (Expand search), "using convolutional data cloning program" (Expand search), "using convolutional data loading program" (Expand search), "using convolutional data cooling programs" (Expand search), "using convolutional data recording program" (Expand search), "using convolutional data crossing 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: "((\"using convolutional data coding program\") OR (\"using compositional data mining program\"))~".
• Removing quotes may allow a broader search: (( using convolutional data coding program ) OR ( using compositional data mining program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using convolutional data coding program") OR ("using compositional data mining program"))*.
