Independent Component Analysis Based on Information Bottleneck

Figure 1

ICA. The synthetic independent data are plotted in (a), and the recovery data are shown in (b) corresponding to the matrix in (17). In terms of every column of the matrix , the substantial entry, , is almost a reflection of the transformation between the original data and the recovery data by multiplying the substantial entry , accompanied by the nonzero entries, . For example, in the first result of the ICA experiments, is just a proof that the original data is recovered into the recovery data with a multiplicator and some noises based on the minor numbers of and .
