Abstract:

This   report   describes  a  connectionist  architecture specifically
intended for use  in sequential domains requiring symbol manipulation.
The architecture  is based on a network  formalism which  differs from
other connectionist networks developed for use  in temporal/sequential
domains.  Units in this formalism are updated synchronously and retain
partial activation between updates.   They  produce two output values:
the standard  sigmoidal function  of the  activity  and its  velocity.
Activation    flowing  along  connections can    be  gated  by  units.
Well-behaved symbol buffers  which learn complex  assignment  behavior
can  be constructed using  gates.  Full  recurrence is supported.  The
network architecture, its underlying formalism, and its performance on
an incremental parsing task requiring non-trivial dynamic behavior are
presented.

This report discusses a connectionist parser built for a smaller task
than was discussed at NIPS.
