Abstract:
In this response to commentators, I agree with those who suggested that the distinction between exemplar- and abstraction-based accounts is something of a false dichotomy and therefore move to an abstractions-made-of-exemplars account under which (a) we store all the exemplars that we hear (subject to attention, decay, interference, etc.) but (b) in the service of language use, re-represent these exemplars at multiple levels of abstraction, as simulated by computational neural-network models such as BERT, ELMo and GPT-3.

Abstract:
Multi-agent systems for a certain application area can be modeled at multiple levels of abstraction. Interlevel relations are a means to relate models from different abstraction levels. Three dimensions of abstraction often occurring are the process abstraction, temporal abstraction, and agent cluster abstraction dimension. In this paper a unifying formalization is presented that can be used as a framework to specify interlevel relations for any of such dimensions. The approach is illustrated by showing how a variety of different types of abstraction relations between multi-agent system models

In this commentary, I discuss why, despite the existence of gradience in phonetics and phonology, there is still a need for abstract representations.

Abstract:
AbstractTo work in a higher abstraction level is of critical importance for the development of multiagent systems (MAS) since it is almost impossible to observe code-level details of such systems due to their internal complexity, distributedness and openness. As one of the promising software development approaches, model-driven development (MDD) aims to change the focus of software development from code to models. This paradigm shift, introduced by the MDD, may also provide the desired abstraction level during the development of MASs. For this reason, MDD of autonomous agents and MASs has been

Abstract:
In large-scale, distributed systems such as Grids, an agreement between a client and a service provider specifies service level objectives both as expressions of client requirements and as provider assurances. From an application perspective, these objectives should be expressed in a high-level, service or application-specific manner rather than requiring clients to detail the necessary resources. Resource providers on the other hand, expect low-level, resource-specific performance criteria that are uniform across applications and can be easily interpreted and provisioned. This paper presents

Abstract:
Popular data mining methods support knowledge discovery from patterns that hold in relations. For many applications, it is difficult to find strong associations among data items at low or primitive levels of abstraction. Mining association rules at multiple levels may lead to more informative and refined knowledge from data. Multi-level association rule mining is a variation of association rule mining for finding relationships between items at each level by applying different thresholds at different levels. In this study, an inventory classification policy is provided. At each level, the loss

Abstract:
Abstract This paper discusses the creative dynamic between abstraction, reification, and reflexivity in the study of religion in general and textual analysis and Indian Buddhist thought in particular. I define “texts” narrowly, as written materials signifying human speech, something doubly removed from sensory experience, inviting abstraction and reification, while enabling reflexive analysis. Such analyses accumulate in literate civilizations — alienating yet enabling us. For example, the critical methods of Biblical analysis ironically undermined its own ahistorical assumptions, e.g., the id

Abstract:
As societal interaction and combination play a vital role in shaping spatio-temporal development paths, meta-theories of uneven development should give way to a relational meta-theory of uneven and combined development (U&CD). U&CD examines at multiple levels of abstraction not just internal causal mechanisms governing the trajectories of individual societies but also causal mechanisms deriving from societal interaction in a world of multiple unevenly developed societies and multiple development pathways. As a consequence it helps explain geographical differentiation and the multiplici

Abstract:
Somewhere along the cortical hierarchy, behaviorally relevant information is distilled from raw sensory inputs. We examined how this transformation progresses along multiple levels of the hierarchy by comparing neural representations in visual, temporal, parietal, and frontal cortices in monkeys categorizing across three visual domains (shape, motion direction, and color). Representations in visual areas middle temporal (MT) and V4 were tightly linked to external sensory inputs. In contrast, lateral prefrontal cortex (PFC) largely represented the abstracted behavioral relevance of stimuli (tas
