Extended experiment 6: Spatiotemporal chromatic CSFs with different training set (not shown in the main text): Convergence. Figure shows the learning curves for the considered architectures on a higher resolution movie (the film The FBI story; LeRoy, 1959). All models converge except the 8-layer architecture. Visual results are not shown due to copyright issues. Interested readers can obtain these specific results from the authors. The local minimum in which the eight layer architecture was trapped has consequences in the complete loss of chromatic information (frame not shown because of copyright issues). Also interesting is the fact that models with four and six layers (which converged as well as the two layer model), substantially over attenuate the red–green channel with the corresponding yellowish–bluish look of the reconstruction and the corresponding impact on the relative scaling of channels in the CSFs, which is not the case for the linear and the two layer solutions.
