Two causes of forgetting have been promulgated: memory trace decay and retroactive interference. The authors show that forgetting is an active process requiring both new learning and memory. In the present (1)Lymnaea model system, prevention of new learning of a conflicting association, inhibition of memory consolidation, or Right Pedal Dorsal 1 soma ablation, which blocks LTM formation, are al...

In a changing environment, forgetting old samples is an e ective method to improve the adaptability of learning systems. However, too fast forgetting causes a decrease of generalization performance. In this paper, we analyze the generalization performance of a learning system with a forgetting parameter. For a class of binary discriminant functions, it is proved that the generalization error is...

200 words max) This paper continues our efforts to model, simulate and ultimately optimize work and knowledge flows in Edge organizations. We use the extended POW-ER 3.0 framework to model and compare two organizational forms (Edge vs. Hierarchy) being used by participants in a counterintelligence student exercise, ELICIT — first without, and then with, learning micro-behaviors enabled in POW-E...

Forgetting, one part of the brain's memory management system, provides balance to the encoding and consolidation of new information by removing unused or unwanted memories or by suppressing their expression. Recent studies identified the small G protein, Rac1, as a key player in the Drosophila mushroom bodies neurons (MBn) for active forgetting. We subsequently discovered that a few dopaminergi...

In the past decades, forgetting has been investigated for many logics and has found many applications in knowledge representation and reasoning. However, forgetting in multi-agent modal logics has largely been unexplored. In this paper, we study forgetting in multi-agent modal logics. We adopt the semantic definition of existential bisimulation quantifiers as that of forgetting. We propose a sy...

Greater working memory capacity is usually associated with greater ability to maintain information in the face of interruptions. In two experiments, we found that some types of interruptions actually lead to greater forgetting among high-span people than among low-span people. Specifically, an instruction designed to change mental context resulted in significant forgetting for high-span people ...

Forgetting is a useful tool for tailoring ontologies by reducing the number of concepts and roles. The issue of forgetting for general ontologies in more expressive description logics, such as ALCQ and SHIQ, is largely unexplored. In this paper, we develop a decidable, sound, and complete tableau-based algorithm to implement the forgetting-based reasoning. Our tableau algorithm is technically f...

The notion of uniform interpolation for description logic ALC has been introduced in [9]. In this paper, we reformulate the uniform interpolation for ALC from the angle of forgetting and show that it satisfies all desired properties of forgetting. Then we introduce an algorithm for computing the result of forgetting in concept descriptions. We present a detailed proof for the correctness of our...

When people are cued to forget a previously studied list of items and to learn a new list instead, such cuing typically leads to forgetting of the first list and to memory enhancement of the second. In two experiments, we examined such listwise directed forgetting in children (and adults), using a forget cue that placed either high emphasis or low emphasis on the need to forget. In the low-emph...
