Order-Based Representation in Random Networks of Cortical Neurons
Figure 8
Sensitivity of classification accuracy to the temporal resolution of sampled latencies to first spike times.
Two examples from two different networks are shown (left and right panels). In the left panel a network that was challenged with a two stimulation sites classification task is shown; the right panel shows a case of a network that was challenged with a six stimulation sites classification task (black horizontal lines depict chance level). Support vector machine (SVM) algorithm was applied (see Materials and Methods and caption of Figure 7). Mean test accuracy (thick lines) and confidence intervals (interrupted lines) are calculated from a 5-fold cross validation procedure per given time resolution. Classification accuracy of first spike latency is depicted Red; that of recruitment order is depicted Blue.
