Figure 3. Spectral clustering results.

Figure 3

Shown are nine clusters obtained by pooling STRFs from the sparse as well as sustained ensembles for Inline graphic10, 25, 50, 125, 250, 500, 1000, and 2500 ms. Shown in the center is a stacked bar chart where segment color corresponds to class label and segment width is proportional to the number of STRFs assigned to a particular class in a given ensemble. The surrounding panels show examples of STRFs drawn from six illustrative classes, namely, noisy, localized, spectral, complex, temporal, and directional.
