Realizing Forgetting in a Modified Sparse Distributed
Proceedings of the 28th Annual Meeting of the Cognitive Science
Society, (pp. 1992-1997), Vancouver, Canada.
|This paper presents research on the development of
effective forgetting mechanisms for the modified Sparse Distributed Memory (SDM)
system, which shows promise to be a good candidate for use as Transient
Episodic Memory (TEM) in software agents such as IDA. Possible theories and
mechanisms for forgetting are retrieval failures, decay and interference.
The SDM architecture has inherent features to effect interference and
retrieval failures. We have implemented two decay mechanisms in the modified
SDM system. In this paper, we present the decay mechanisms and the
experimental results. We argue that the decay mechanisms compliment the
inherent features of the SDM architecture in realizing forgetting for TEM.
