Results of SIM. We display the mean sensitivity (left plots) and mean specificity (right plots) against five experimental settings: (1) w_{u|v, k} ∈ [-ε, ε ] (independent data), (2) w_{u|v, k} ∈ [-0.5, 0.5], (3) w_{u|v, k} ∈ [-1, 1], (4) w_{u|v, k} ∈ [-1.0, -0.5] ∪ [0.5, 1] and (5) w_{u|v, k} ∈ [-1, -1 + ε] ∪ [1 – ε, 1]. The dependence increases with experiment number. On the top plots, k-means results are displayed in blue, SOM in green and mixture of dependence trees with MAP estimation (MixDTrees) in red. On the bottom plots, mixture of Gaussians with full covariance matrices are displayed in yellow, mixture of Gaussians with diagonal covariance matrices in purple, Mixture of dependence trees with MLE estimation in light blue (MixDTrees-MLE) and mixture of dependence trees with MAP estimation (MixDTrees-MAP) in red.
