| Abstract(in English) | To understand information processing in the brain, it is important to clarify the connectivity between neurons. We have already proposed the method of estimating connectivities between neurons only from observed multiple spike sequences by quantifying distance between spike sequences. To quantify distance between spike sequences, the spike time metric is used. However, the spike time metric involves a parameter. Then, we have to set an optimal parameter in the spike time metric. In this report, we used the SPIKE-distance instead of the spike time metric. The SPIKE-distance is a parameter-free measure which can quantify the distance between spike sequences. Using the SPIKE-distance, we estimate the network structure. As a result, the proposed method exhibits higher performance than the previous method. |
