Integrating structure and meaning: a distributed model of analogical mapping
In this paper we present Drama, a distributed model of analogical mapping that integrates semantic and structural constraints on constructing analogies. Specifically, Drama uses holographic reduced representations (Plate, 1994), a distributed representation scheme, to model the effects of structure and meaning on human performance of analogical mapping. Drama is compared to three symbolic model...
متن کاملIntegrating Form and Meaning: A Distributed Model of Speech Perception
ion is common in connectionist simulations of linguistic tasks (e.g. Elman, 1990, 1993), and may also be occurring in our network, but subject to the constraint that relevant phonetic detail is not lost as a result. Indeed, such weak abstraction is functionally equivalent to the direct access from features approach. Competition Across Word Boundaries and Segmentation Our discussion of competiti...
متن کاملA Distributed Basis for Analogical Mapping
We are concerned with the practical feasibility of the neural basis of analogical mapping. All existing connectionist models of analogical mapping rely to some degree on localist representation (each concept or relation is represented by a dedicated unit/neuron). These localist solutions are implausible because they need too many units for human-level competence or require the dynamic re-wiring...
متن کاملDistributed Representations of Structure: A Theory of Analogical Access and Mapping
This article describes an integrated theory of analogical access and mapping, instantiated in a computational model called LISA (Learning and Inference with Schemas and Analogies). LISA represents predicates and objects as distributed patterns of activation that are dynamically bound into propositional structures, thereby achieving both the flexibility of a connectionist system and the structur...
