This paper presents research on the development of effective forgetting mechanisms for the Sparse Distributed Memory (SDM) system, to computationally model Transient Episodic Memory (TEM), a short-term sensory perceptual episodic memory in software agents.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 a variant of the SDM system.In this paper, we present the decay mechanisms and the experimental results.The results show that the decay mechanisms compliment the inherent features of the SDM architecture in realizing forgetting for TEM.
