Let’s compare the performance of a pair of networks both with and without population coding, and train them for one single time step. from snntorch import surrogate # network parameters num_inputs = 28*28 num_hidden = 128 num_outputs = 10 num_steps = 1 # spiking neuron parameters beta = 0.9 # neuron decay rate grad = surrogate ... WebJan 1, 2015 · The neuronal populations within a given region are highly heterogeneous, with cell types of different function intermingled with ... our results in no way contradict the well-established importance of spatial coding in olfaction. Coding by spatial patterns of glomerular activation and coding by sniff phase are not mutually ...

Hopfield model: latency coding. Hopfield (1995) proposed a theoretical model for pattern recognition. The model assumes common oscillatory inputs to a population of neurons. When these neurons receive different levels of constant input, those receiving stronger input fire early flying bicycle plane

WebNov 22, 2011 · As an extension to this work, the proposed latency coding scheme provided a direct input for designing bio-inspired data analysis methods for artificial olfaction in electronic noses . In latency coding, one considers the neurons as analog to delay converters: the most strongly activated neurons tend to fire first, whereas more weakly … WebStudy of the Coding Efficiency of Populations of Olfactory Receptor Neurons and Olfactory Glomeruli Review.
