Ultraviolet protection factor calculating apparatus and ultraviolet protection factor calculating method

An ultraviolet protection factor calculating apparatus comprising:

• an input interface configured to receive unit cosmetic input information;
• a memory configured to store a database including data mapping a plurality of cosmetic information items with a plurality of ultraviolet protection factors, respectively;
• and
• a controller configured to:
• generate a decision tree having at least one of the plurality of cosmetic information items set as an explanatory variable and at least one of the plurality of ultraviolet protection factors set as a dependent variable based on the database,
• receive the cosmetic input information via the input interface,
• determine an ultraviolet protection factor corresponding to the cosmetic input information based on an output of the decision tree, and
• output the ultraviolet protection factor corresponding to the cosmetic input information.

A method for controlling an ultraviolet protection factor calculating apparatus, the method comprising:

• receiving, via one or more processors in the ultraviolet protection factor calculating apparatus, cosmetic input information;
• inputting, via the one or more processors, the cosmetic input information into a decision tree having at least one of a plurality of cosmetic information items set as an explanatory variable and at least one of a plurality of ultraviolet protection factors set as a dependent variable based on data mapping one or more of the plurality of cosmetic information items with one or more of the plurality of ultraviolet protection factors;
• determining, via the one or more processors, an ultraviolet protection factor corresponding to the cosmetic input information based on an output of the decision tree;
• and
• outputting the ultraviolet protection factor corresponding to the cosmetic input information.
