nengo_spa.testing

Support for unit testing SPA models.

Functions

assert_sp_close(t, data, target_sp[, skip, …])

Test that the RMSE to a Semantic Pointer is below threshold.

nengo_spa.testing.assert_sp_close(t, data, target_sp, skip=0.0, duration=None, atol=0.2, normalized=False)

Test that the RMSE to a Semantic Pointer is below threshold.

Parameters

t(T,) array_like

Time values for data in seconds, usually obtained with nengo.Simulator.trange.

data(T, D) array_like

Simulation data for T timesteps and D dimensions.

target_spSemanticPointer

Target Semantic Pointer.

skipfloat, optional

Amount of seconds to ignore at the beginning of the data.

durationfloat, optional

Amount of seconds to consider after the skipped portion.

atolfloat, optional

Absolute tolerated RMSE.

normalizebool, optional

Whether to normalize the simulation data to unit length in each timestep.
