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

Table 2

Comparison of the decoding accuracy based on the combination of all features from each of cluster 1–4 (denoted as c1 (combined)–c4 (combined), resp.), and the single best feature from each of cluster 1–4 (denoted as c1 (best)–c4 (best), resp.). Clusters 1–4 correspond to high gamma band (50–60 Hz), delta band (1–4 Hz), alpha band (10–20 Hz), and low gamma band (30–40 Hz), respectively. The sparse NTF approach based on minimization of the generalized KL divergence is used.
