Perhaps you should try some spelling variations:
"progressive transformation priors" » "processing transformation priors", "projective transformation priors", "projective transformations priors", "progressive transformation prior", "progressive transformation priority", "progressive transformation period"
"progressive deformation priors" » "progressive depreciation priors", "progressive relaxation priors", "progressive education priors", "progressive deformation prior", "progressive information prior", "progressive deformation pore"

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: "((\"progressive deformation priors\") OR (\"progressive transformation priors\"))".
• Removing quotes may allow a broader search: (( progressive deformation priors ) OR ( progressive transformation priors )).
• Adding a wildcard symbol may retrieve word variants: (("progressive deformation priors") OR ("progressive transformation priors"))*.
