Signal
propagation: (
a
) signals from
the two query nodes are sent
to the video template nodes,
and three video nodes
{
are activated; (
b
)the
signal propagates back from
the third layer to the second
layer, resulting in more
activated video temple nodes;
(
c
) the signal propagates
forward to the third layer.
This results in the activation
of new video nodes (i.e.,
nodes
c
,
d
,
e
}
)by
expanding the original query
nodes and the activated video
nodes in (
b
)
{
c
,
d
,
e
,
i
}
First, each query template node is assigned a fixed activation level equal to
a
(
q
)
=
r
,
∈
[

]
1
. Then, its signal to the video template node is attenuated by normalized
query template weights
w
qr
, as follows:
