[1705.05475] Sparse Coding by Spiking Neural Networks: …

Information in the brain is represented as action potentials (neuron spikes), which may be grouped into spike trains or even coordinated waves of brain activity. A fundamental question of neuroscience is to determine whether neurons communicate by a rate or temporal code. Temporal coding suggests that a single spiking neuron can replace hundreds of hidden units on a sigmoidal neural net. WebNov 24, 2024 · Rank Order Coding and Population Order Coding. To alleviate this problem, a wide variety of algorithms have been proposed, such as Rank Order Coding (ROC) 9 or Population Order Coding (POC) 10. ROC encodes the information in the order the spikes arrive, over a given time window, with the first spike meaning the highest value of the signal. irc 430 h 2 https://mmservices-consulting.com

WebOct 8, 2024 · TTFS is a time-coding technique in which neurons’ activity is proportional to their firing delay. During inference, neurons with TTFS coding emit a single spike and send information using the spike’s timing. It is worth noting that once a neuron generates a spike, it cannot generate more spikes when a suitably long refractory period is applied.
