Performance evaluation of the decomposition algorithms (red points) with stICA08 (blue points) as the reference algorithm. The comparison between the algorithms’ performance is based on (1) firing pattern agreement between the components and the EMG reference (RoA), and (2) agreement between the different algorithms’ identified component sets (CIDR). The components’ RoA values were divided into groups; A high-success group (75% ≤ RoA ≤ 100%), and B semi-success group (50% ≤ RoA < 75%). Note that the number of components at the x-axis denotes each algorithm’s number of components within the pre-defined group (high-success or semi-success)
