CDN.java - Conditional Dependency Networks. A fully connected undirected network, each node (label) is connected to each other node (label). Each node is a binary classifier that predicts p(y_j|x,y_1,...,y_{j-1},y_{j-1},...,y_L). Inference is done using Gibbs sampling over I iterations. The final I_c iterations are used to collected the marginal probabilities, which becomes the prediction y[].
