Figure 3From: Brain-Computer Interface Controlled Functional Electrical Stimulation System for Ankle MovementHistograms of the posterior class probabilities for subject B. Based on the known underlying action (idling or dorsifiexion), the distributions of the posterior probabilities, P ( D | f ⋆ ∈ I ) and P ( D | f ⋆ ∈ D ) , are empirically estimated as histograms. Dashed lines indicate the 25%, 50%, and 75% quartiles, where the 25% and 50% quartiles for P ( D | f ⋆ ∈ I ) overlap. Note that P ( D | f ⋆ ∈ I ) =1-P ( I | f ⋆ ∈ I ) .Back to article page
