Perhaps you should try some spelling variations:
"advanced validation with python programming" » "advanced oxidation with python programming" (Expand search), "advanced glication with python programming" (Expand search), "advanced visualization with python programming" (Expand search), "advanced validation in python programming" (Expand search), "advanced validation method python programming" (Expand search)
"deep convolution and cooking program" » "deep convolutional and cooking program" (Expand search), "deep convection and cooking program" (Expand search), "beam convolution and cooking program" (Expand search), "deep evolution and cooking program" (Expand search), "deep revolution and cooking program" (Expand search), "deep convention and cooking program" (Expand search), "deep convolution and cooling programs" (Expand search), "deep convolution and smoking program" (Expand search), "deep convolution and cloning program" (Expand search), "deep convolution and cooling 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: "((\"deep convolution and cooking program\") OR (\"advanced validation with python programming\"))~".
• Removing quotes may allow a broader search: (( deep convolution and cooking program ) OR ( advanced validation with python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("deep convolution and cooking program") OR ("advanced validation with python programming"))*.
