چکیده
Measuring the transmitted information in metric-based clustering has become something of a standard test for the performance of a spike train metric. In this comment, the recently proposed Lp VictorPurpura metric is used to cluster spiking responses to zebra finch songs, recorded from field L of anesthetized zebra finch. It is found that for these data the Lp metrics with p > 1 modestly outperform the standard, p = 1, Victor-Purpura metric. It is argued that this is because for larger values of p, the metric comes closer to performing windowed coincidence detection.

متن کاملA Fast p Spike Alignment Metric
The metrization of the space of neural responses is an ongoing research program seeking to find natural ways to describe, in geometrical terms, the sets of possible activities in the brain. One component of this program is spike metrics-notions of distance between two spike trains recorded from a neuron. Alignment spike metrics work by identifying "equivalent" spikes in both trains. We present ...

متن کاملA Ciric-type common fixed point theorem in complete b-metric spaces
In this paper, we define the concept of compatible and weakly compatible mappings in b-metric spaces and inspired by the Ciric and et. al method, we produce appropriate conditions for given the unique common fixed point for a family of the even number of self-maps with together another two self-maps in a complete b-metric spaces. Also, we generalize this common fixed point theorem for a seq...
