8. The method of claim 7 , where aggregating the M classification score vectors comprises one of: finding an average of all M classification score vectors: S ⇀ = ∑ i = 1 M ⁢ S ⇀ i ; and finding a maximum of all M classification score vectors: S ⇀ = Max i ⁡ [ S ⇀ i ] .
7. A method, comprising: obtaining from an online social media site a plurality of instances of images of objects associated with a person; analyzing with a data processor the plurality of instances of the images with a plurality of predetermined style classifiers to obtain a score for each image for each style classifier; and determining with the data processor, based on the obtained scores, a likely preference of the person for a particular style of object; where the method further comprises an initial step performed, for a subject category of interest having a plurality N of sub-categories, where N is an integer greater than one, training over a first set of images a plurality of image classifiers to yield a plurality of pre-trained classifiers (C 1 . . . C N ), where each individual one of the pre-trained classifiers is trained to recognize one sub-category of the plurality of sub-categories; where the step of obtaining comprises obtaining a second set of images (i=1 . . . M) from at least one social media website that a person has shared/posted/pinned or otherwise expressed an interest in, where M represents a total number of images in the second set of images; and where the steps of analyzing and determining comprise, applying at least some of the pre-trained classifiers (C 1 . . . C N ) to each image i in the second set of images; obtaining a classification score vector {right arrow over (S)} i =[s 1 . . . s N ] for image i(i=1 . . . M), where s j indicates a classification score output from a classifier C j by applying it to image i; aggregating the M classification score vectors over all of the images of the second set of images; deriving a data construct that is descriptive of a preference profile of the person with respect to the sub-categories of the category of interest as a probability distribution over the N sub-categories; and characterizing by how much the person's profile differs from an average profile of a group of persons by assigning the person to a segment, where P a represents a probability vector for the person, and calculating an average P segment _ i for each segment i, where a degree to which the person is a member of the segment i is a dot product of the two vectors: 
 P a• P segment _ i /(| P a | |P segment _ i |).
