    If we have two classifiers h 1 and h 2 with (fp1,fn1) and (fp2,fn2), then we can construct a stochastic classifier that interpolates between them. Given a new data point x, we use classifier h 1 with probability p and h 2 with probability (1 p). The resulting classifier has an expected false positive level of p fp1 + (1 p) fp2 and an
