Table 7 summarizes the results and gives the accuracy of the all male baseline as well as of the propagation procedure (Prop-acc).
the exact procedure is as follows: given user u connected with videos V u = {v 1 , ..., v m }, there are m gender distributions sent to u: to address the skewness in the data, i.e., the fact that 70% of our users (62/(26 + 62)) with known gender are male, we select the female gender if (a) it got more than zero mass and at least as much mass as male:p(f ) > 0 ∧p(f ) ≥p(m), or (b) it got at least τ of the mass:p(f ) ≥ τ .
