Figure 7.
An example from one Monte Carlo run illustrating that ARD can effectively determine the source number. (A) Hinton diagram of the true mixing matrix A. (B) Hinton diagrams of ÂVB, whose Amari index is 0.1365. (C) Hinton diagram of ÂCSP, whose Amari index is 2.0726. (D) Hinton diagram of ÂInfomax, whose Amari index is 2.4259. Each entry in the matrices is represented by the size of the area of a red (positive value) or green (negative value) square.
