Ensemble Fractional Sensitivity: A Quantitative Approach to Neuron Selection for Decoding Motor Tasks

Figure 4

Distribution of fractional sensitivities for four exemplary neurons, using an ensemble of 500 nonlinear models. Note that although an ensemble of 10 models is used for neuron selection, 500 models are shown here to illustrate that fractional sensitivities cluster around a mean value. Histogram plots arranged according to the rank of the neurons (marked on top right in each plot). Mean fractional sensitivity for each neuron is represented by black scatter points.
