Perhaps you should try some spelling variations:
"software validation from python programming" » "software validation flow python programming" (Expand search), "software validation of python programming" (Expand search), "software validation on python programming" (Expand search), "software validation from pathogen programming" (Expand search), "software validation from anthony programming" (Expand search)
"deep convolutional codes using program" » "deep convolutional codes housing program" (Expand search), "deep convolutional codes nursing program" (Expand search), "deep convolutional codes aging program" (Expand search), "deep convolutional code using program" (Expand search), "deep convolutional nodes using program" (Expand search), "deep convolutional modes using program" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("deep convolutional codes using program") OR ("software validation from python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"deep convolutional codes using program\") OR (\"software validation from python programming\"))".
• Removing quotes may allow a broader search: (( deep convolutional codes using program ) OR ( software validation from python programming )).
• Adding a wildcard symbol may retrieve word variants: (("deep convolutional codes using program") OR ("software validation from python programming"))*.
