We present an algorithm that computes a depth-three threshold circuit for the classiication of liver tissue. The circuit is calculated from a sample set S of 348 positive (abnormal ndings) and 348 negative (normal liver tissue) examples by a local search strategy. The local search is based on simulated annealing with the logarithmic cooling schedule c(k) =(More)
