[nengo-user] Seeing the decoded values in nengo

[Chris Eliasmith]

Hi,

In the latest release, you can probe the connection to find the decoders:

connection = nengo.Connection(a,b)
decoders_p = nengo.Probe(connection, 'decoders', sample_every=1, 
synapse=None)

sample_every tells the sim how often to collect the values (full example 
below).

best, .c

PS if you're using the latest dev version, you need to do it differently.

-------------

import nengo

model =  nengo.Network()
with model:
     stim = nengo.Node([0])
     a = nengo.Ensemble(20, 1)
     b = nengo.Ensemble(20, 1)
     nengo.Connection(stim, a)
     connection = nengo.Connection(a, b)

     decoders_p = nengo.Probe(connection, 'decoders', sample_every=1, 
synapse=None)

sim = nengo.Simulator(model)
sim.run(2.0)
print sim.data[decoders_p][-1,:] #Print the last decoder sample
