This network consists of two types of neurons. The regular neurons and
the so called context neurons. In such networks all links leading to
context units are considered recurrent links.
The initialization function JE_Weights requires the
specification of five parameters:
- , :
The weights of the forward connections are randomly chosen
from the interval . have to be
provided in field1 and field2 of the init panel.
- :
Weights of self recurrent links from context units to themselves.
Simple Elman networks use . has to be
provided in field3 of the init panel.
- :
Weights of other recurrent links to context units. This value
is often set to . has to be provided in field4
of the init panel.
- :
Initial activation of all context units. has to be provided
in field5 of the init panel.
Please note that it is required that . If this
should not be the case, an error message will appear on the screen.
The context units will be initialized as described above. For all other
neurons the bias and all weights will be randomly chosen from the
interval .
