                          Abstract
A connectionist model for robust reasoning, CONSYDERR, is proposed
to account for some common reasoning patterns found in commonsense 
reasoning and to remedy the brittleness problem.
A dual representation scheme is devised, which utilizes both 
localist representation and distributed representation with features.
We explore the synergy resulted from the interaction
between these two types of representations, which helps to deal 
with problems such as partial information, no exact match, property
inheritance, rule interaction, etc.  Because of this, the CONSYDERR 
system is capable of accounting for many difficult patterns in 
commonsense reasoning.
This work also shows that connectionist models of reasoning are 
not just an ``implementation" of their symbolic counterparts,
but better computational
models of common sense reasoning, taking into consideration
of the approximate, evidential and adaptive nature of reasoning, 
and accounting for the spontaneity and parallelism in reasoning 
processes.
