Oesterreichisches Forschungsinstitut fuer Artificial Intelligence (OeFAI) Schottengasse 3, A-1010 Wien Tel.+43-1-53532810,5336112 ------------------------------------------------------------------------- VORTRAG ******* Dr.Peter TINO Slovak University of Technology Bratislava 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).
