Neural Modeling of Complex Symbolic Sequences
---------------------------------------------

We study the problem of modeling long, complex symbolic sequences
with recurrent neural networks  and stochastic machines. The talk 
will be focused on the following issues:

1. What do we mean by saying that a long symbolic sequence is 
   complex?
2. How to monitor the training process in which recurrent networks  
   are trained on complex sequences? (We use information theory 
   based performance measures.)
3. How to extract the knowledge the recurrent net has gained during 
   the training process? (We use stochastic finite state machine 
   representations.)
4. How do we know the extracted machine represents the original 
   network well?
5. We shall present a tool for an "intelligent" transformation of 
   a sequence temporal symbolic structure into a spatial fractal 
   representation and present theorems supporting the claim that 
   this transformation is "intelligent".
6. We show how to build context dependent variable length "Markov 
   systems" from spatial representations of temporal sequence 
   structures (analogical to approaches of Ron, Singer and Tishby).
