Abstraction (from the Latin abs, meaning away from and trahere , meaning to draw) is the process of taking away or removing characteristics from something in order to reduce it to a set of essential characteristics. In object-oriented programming, abstraction is one of three central principles ...
String representations of data values are especially important in an interactive language such as Python that automatically displays the string representation of the values of expressions in an interactive session.为了更有效率的表示数据,一个对象值应该表现得像它旨在表示的数据,包括其自身的字符串表示。

Notably, algorithms evaluated in this work use unsupervised learning and do not train on labelled data, meaning we use both datasets exclusively for evaluation. As a result, we refer in this work to these datasets as ARC-Easy and ARC-Hard respectively. Core knowledge Each task is designed to...
Jurafsky (1996) radial category model of diminutives is based on four kinds of semantic shifts from the central meaning 'small'--metaphor, conventionalization of inference, generalization and lambda abstraction specification. Diminutives in action: a cognitive account of diminutive verbs and their suff...
Software design, functional programming, and software engineering practices Over 5,000 subscribers Summary:We explore some of the background behind the meaning of the word abstraction and why we do it. For a term we use so much in our field, there are very few definitions ofabstraction. And ...
In fact, the abstraction that is at work in object-oriented programming is a prime way to show how powerfully these ideas support virtual “worlds” — when programmers can spin up all manner of virtual objects with their own attributes, they can more effectively model the real world, the ...
See if you can understand the meaning of the warped trajectories on the "unbent" road, by driving the car along the bent road above it, and comparing how the marker moves. Notice how the interaction ties together the abstract representations, as well as provides steps down to the more ...
Moreover, it supports mutability of attribute, meaning that if access attributes are changed while the access is in progress and this change leads to unsatisfaction of the security policy, the granted access is revoked and the usage is cancelled. More details about UCON model are given in [60...
. 3is Cognalytics, a high-level reference architecture for implementing cognitive analytics. It is a layered architecture and the circled numbers on the right denote layer numbers. We use the terms system and architecture synonymously, and the context should help to elucidate the intended meaning....
