Spike latency code

WebJun 22, 2011 · Surprisingly, despite being based on only a single spike, the accuracy of the latency code is comparable to that of a conventional rate code computed over the entire response. We show that spontaneous firing limits the capacity of the latency code to accumulate information from large neural populations. This detrimental effect can be … Weblatency encoding spike train of features or labels Return type: torch.Tensor snntorch.spikegen.latency_code(data, num_steps=False, threshold=0.01, tau=1, first_spike_time=0, normalize=False, linear=False, epsilon=1e-07) [source] Latency encoding of input data. Convert input features or target labels to spike times.

Webcodes also use different subsets of cells in signaling but the latency codes turn out to need orders of magnitude less cells to achieve equivalent precision and confidence levels. Another important consequence of a latency code is that it is compatible with spike timing dependent plasticity (STDP; Bi and Poo, 1998). WebOct 1, 2012 · For large populations, spike count and latency codes performed similarly; for small ones, decoding was more accurate using the latency code. Our findings indicate that whisker deflection direction is more efficiently encoded by spike timing than by spike count. kitchenaid keukenmachine classic https://azambujaadvogados.com

WebDec 3, 2008 · A particular example for a temporal code is the “latency code,” where the arrival time of the first spike after the onset of a stimulus contains the stimulus information (Thorpe, 1990; Gawne et al., 1996; Johansson and Birznieks, 2004; Gollisch and Meister, 2008). As a reference time for a spike in a temporal code, one typically considers ... WebApr 1, 2024 · Here we present a SNN model that uses spike-latency coding (Chauhan et al. 2024, 2024) and winner-take-all inhibition (WTA-I) (Maass 2000) to efficiently represent visual stimuli using multi-scale parallel processing.
