Language support for feature mixing

چکیده
Object oriented languages cannot express certain composition abstractions due to restricted abstraction power. A number of approaches, like SOP or AOP overcome this restriction, thus giving the programmer more possibilities to get a higher degree of separation of concern. We propose forms, extensible mappings from labels to values, as vehicle to implement and reason about composition abstractions. Forms unify a variety of concepts such as interfaces, environments, and contexts. We are prototyping a composition language where forms are the only and ubiquitous first class value. Using forms, it is possible compose software artifacts focusing on a single concern and thus achieve a high degree of separation of concern. We believe that using forms it also possible to compare and reason about the different composition mechanisms proposed.

Target Detection Improvements in Hyperspectral Images by Adjusting Band Weights and Identifying end-members in Feature Space Clusters
Spectral target detection could be regarded as one of the strategic applications of hyperspectral data analysis. The presence of targets in an area smaller than a pixel’s ground coverage has led to the development of spectral un-mixing methods to detect these types of targets. Usually, in the spectral un-mixing algorithms, the similar weights have been assumed for spectral bands. Howe...
متن کاملMixing Languages during Learning? Testing the One Subject—One Language Rule
In bilingual communities, mixing languages is avoided in formal schooling: even if two languages are used on a daily basis for teaching, only one language is used to teach each given academic subject. This tenet known as the one subject-one language rule avoids mixing languages in formal schooling because it may hinder learning. The aim of this study was to test the scientific ground of this as...
متن کاملFeature Selection Using Multi Objective Genetic Algorithm with Support Vector Machine
Different approaches have been proposed for feature selection to obtain suitable features subset among all features. These methods search feature space for feature subsets which satisfies some criteria or optimizes several objective functions. The objective functions are divided into two main groups: filter and wrapper methods. In filter methods, features subsets are selected due to some measu...

As a former Portuguese colony, Macao is the only region in China where Cantonese, a variety of Chinese, and English, an international language, are enjoying de facto official statuses, with Putonghua being a quasi-official language and Portuguese being another official language. Recently, with an increasing number of Mainland Chinese students crossing the border to pursue their tertiar...
متن کاملSmall Statistical Models by Random Feature Mixing
The application of statistical NLP systems to resource constrained devices is limited by the need to maintain parameters for a large number of features and an alphabet mapping features to parameters. We introduce random feature mixing to eliminate alphabet storage and reduce the number of parameters without severely impacting model performance.

Abstract- With the advancement and development of computer network technologies, the way for intruders has become smoother; therefore, to detect threats and attacks, the importance of intrusion detection systems (IDS) as one of the key elements of security is increasing. One of the challenges of intrusion detection systems is managing of the large amount of network traffic features. Removing un...
