Understanding the computation of time using neural network models
Zedong Bi, Changsong Zhou
To maximize future rewards in this ever-changing world, animals must be able to discover the temporal structure of stimuli and then anticipate or act correctly at the right time. H…

Understanding the computational difficulty of a binary-weight perceptron and the advantage of input sparseness
Zedong Bi, Changsong Zhou
Limited precision of synaptic weights is a key aspect of both biological and hardware implementation of neural networks. To assign low-precise weights during learning is a non-triv…

Spike Pattern Structure Influences Efficacy Variability under STDP and Synaptic Homeostasis
Zedong Bi, Changsong Zhou, Hai-Jun Zhou
In neural systems, synaptic plasticity is usually driven by spike trains. Due to the inherent noises of neurons, synapses and networks, spike trains typically exhibit externally un…
