Perhaps you should try some spelling variations:
"using compositional data learning program" » "using computational data learning program" (Expand search), "in compositional data learning program" (Expand search), "music compositional data learning program" (Expand search), "using compositional data learning programme" (Expand search), "using compositional data learning problems" (Expand search), "using compositional data learning process" (Expand search), "using compositional meta learning program" (Expand search), "using compositional data cleaning program" (Expand search), "using compositional java learning 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 learning program\"))~".
• Removing quotes may allow a broader search: (( using convolutional data coding program ) OR ( using compositional data learning program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using convolutional data coding program") OR ("using compositional data learning program"))*.
