A GM for the problem of learning genders of boys and girls from a table of their heights and weights. The gender of the nth child is denoted z n . The 2-dimensional vector of the child’s height and weight is denoted d n The mean hight and weight for each gender, variances of height and weight for each gender, and probability of belonging to each gender are denoted by , , and , respectively. Observed variables are represented by open circles, hidden variables are represented by filled circles, and fixed parameters are represented by dots. To avoid drawing nodes for all N hidden and observed variables, the variables are shown once and placed inside a plate which denotes the number or repetitions in the lower right corner. This GM specifies the conditional factorization of shown in Eq. 1.
