Table 1.

Parameters used in the execution time and accuracy benchmarks.

Synapse model
Parameters	τ_{z_i} = 10 ms presynaptic Z trace time constant
	τ_{z_j} = 15 ms postsynaptic Z trace time constant
	τ_e = 20ms E trace time constant
	τ_p = 1000 ms P trace time constant
	κ = 1 learning rate
	ϵ = 0.001 minimum activity

Note that the values represent only one possible parameter set. Plausible ranges for the time constants are given in the text (Section 2.1.1). The execution time is not affected by the choice of the parameters, but, of course, the accuracy results may change when using different parameters.
