We show how the PEPA performance modelling language could be extended with a feature construct which can be used to describe modifications to PEPA models. We provide this construct with an operational description which conservatively extends the operational semantics of the PEPA language. We then show how the feature construct can be applied in a small

Construction of texture features
2009 Proceedings of 6th International Symposium on Image and Signal Processing and Analysis, 2009One well-known and effective method used for computationally efficient texture classification is the use of statistical information on 3×3 pixel blocks such as local binary patterns (LBP). However, there has been negligible research on sizes of pixel blocks beyond 3×3 while using the histogram approach. Specifically, larger or non-square features might

Feature Construction during Tree Learning
1991This paper addresses the “problem of new terms” in the context of learning decision trees using the approach based on ID3. We discuss an algorithm for efficiently constructing new features from given primitive features and relate it to constructive induction.

Figurative features and the construction of visual images
Psychological Research, 1983Within the framework of a featural approach to conceptual representations, “figurative features” were defined as cognitive entities reflecting the sensory properties of objects in the human mind. In conceptual hierarchies such as taxonomies, “primary concepts” were defined as the most abstract concepts which could still be characterized by their ...

Efficient Construction of Relational Features
Fourth International Conference on Machine Learning and Applications (ICMLA'05), 2006Devising algorithms for learning from multi-relational data is currently considered an important challenge. The wealth of traditional single-relational machine learning tools, on the other hand, calls for methods of 'propositionalization', i.e. conversion of multi-relational data into single-relational representations.

CONSTRUCTING SURFACE FEATURES THROUGH DEFORMATION
International Journal of Image and Graphics, 2010A frequent problem in computer aided mechanical design is the construction of arbitrarily-shaped ribs and beads on surfaces, to increase their rigidity or for aesthetic reasons. We improve upon a previous mathematical approach for defining such ribs and beads, based on using so-called extension functions to define a deformation matrix, which is then ...

MDL-based fitness for feature construction
Proceedings of the 9th annual conference on Genetic and evolutionary computation, 2007Primitive data representation of real-world data facilitates attribute interactions, which make information opaque to most learners. Feature Construction (FC) aims to abstract and encapsulate interactions into new features and outline them to the learner. When a GA is applied to perform FC, the goal is to generate features that facilitate more accurate

Feature++: Automatic Feature Construction for Clinical Data Analysis
2016With the rapid growth of clinical data and knowledge, feature construction for clinical analysis becomes increasingly important and challenging. Given a clinical dataset with up to hundreds or thousands of columns, the traditional manual feature construction process is usually too labour intensive to generate a full spectrum of features with potential ...

A Study on the Construction Features of “Pan X”
2021From the diachronic and synchronic perspectives, this paper conducts a comprehensive study on the structural features of the online buzzword “pan (盘) X” which has become popular since 2019. At the diachronic level, the “pan (盘) X” construction, in the process of evolving from a grammatical construction to a rhetorical construction, on the one hand ...
