Single-Trial Decoding of Bistable Perception Based on Sparse Nonnegative Tensor Decomposition

Figure 6

The representative time-frequency plot for (a) cluster 1, (b) cluster 2, (c) cluster 3, and (d) cluster 4, respectively, of the sparse NTF components. Red and blue represent strong and weak activity, respectively. Note that the first cluster for the sparse NTF components contains only one component in the high gamma band (50–60 Hz) with well-localized time-frequency representation, and that clusters 2–4 have concentrated time-frequency distributions in the delta band (1–4 Hz), alpha band (10–20 Hz), and low gamma band (30–40 Hz), respectively.
