alzheimer's disease (ad) is the most common form of neurodegenerative disorders. memory loss in an alert person and impairment in the function of language, attention, perception, judgment or problem solving can occur in patients with ad. however, there are some medications in order to delay the debilitating aspects of the disease; but unfortunately, scientists could not found approaches to...

One of the fundamental human cognitive processes is problem solving. As a higher-layer cognitive process, problem solving interacts with many other cognitive processes such as abstraction, searching, learning, decision making, inference, analysis, and synthesis on the basis of internal knowledge representation by the object–attribute-relation (OAR) model. Problem solving is a cognitive process ...

In this paper we present a multi agent and multi issue negotiation model which can be used for guiding agents during distributed problem solving. This model is composed of protocols which g o vern and manage agent interactions , and an agent architecture which represents decision and action mechanisms which assist agents during distributed problem solving processes.

To control problem solving activity, a planner must resolve uncertainty about which specific long-term goals (solutions) to pursue and about which sequences of actions will best achieve those goals. In this paper, we describe a planner that abstracts the problem solving state to recognize possible competing and compatible solutions and to roughly predict the importance and expense of developing...

Local differential privacy has recently surfaced as a strong measure of privacy in contexts where personal information remains private even from data analysts. Working in a setting where both the data providers and data analysts want to maximize the utility of statistical analyses performed on the released data, we study the fundamental trade-off between local differential privacy and utility. ...

Crowdsourcing has gained much attention in practice over the last years. Numerous companies have drawn on this concept for performing different tasks and value creation activities. Nevertheless, despite its popularity, there is still comparatively little well-founded knowledge on crowdsourcing, particularly with regard to the governance of crowdsourcing initiatives. Although proper governance i...

The ability to solve problems effectively is one of the hallmarks of human cognition. Yet, in our opinion it gets far less research focus than it rightly deserves. In this paper we outline a framework in which this effectivity can be studied; we identify the possible roots and scope of this effectivity and the cognitive processes directly involved. More particularly, we have observed that peopl...
