Patent ID: 7587331

Claim:
A method for determining a scent or taste profile of a user comprising: storing in a computerized system for each of a set of products chosen among products for which a database includes smell or taste prints constituted by a set of measurements given by smell or taste electronic sensors, a satisfaction note rating (SN) given by the user; automatically calculating by the computer weighting coefficients constituting said profile and respectively affected to said sensors measurements, by successive approximation of sets of weighting coefficients leading to minimizing the sum of the quadratic errors over the set of satisfaction notes; and selecting a product based on said weighting coefficients constituting said profile; wherein the weighting coefficients of the user's profile are determined by minimizing the result of the following formula by successive approximation of sets of weighting coefficients α j , ∑ h = 1 q ⁢ ⁢ ( S ⁢ ⁢ P h - ∑ j = 1 n ⁢ ( α j · MV j , h ) ) 2 , where SN h — designates the rating given by the user for the product of rank h of said set of q products, where α j designates the weighting coefficient of rank j affected to the product of rank j of the smell or taste prints, and where MV j,h designates the scores of rank j of the smell print of product of rank h.
