A Hierarchical Neuronal Model for Generation and Online Recognition of Birdsongs
Figure 7
First simulation ‘Ideal communication’: The dynamics of song generation (left two columns) and song recognition (right two columns) with arbitrary units.
The format and the generated dynamics are the same as shown in Figure 5. The recognition scheme receives only the output of the first level (bottom left) and reconstructs states at all levels using the online Bayesian inference scheme. It can be seen that the reconstruction is successful as there are only tiny deviations between the true (left) and the reconstructed (right) dynamics.
