N-gramas sintácticos no-continuos

In this paper, we present the concept of noncontinuous syntactic n-grams. In our previous works we introduced the general concept of syntactic n-grams, i.e., n-grams that are constructed by following paths in syntactic trees. Their great advantage is that they allow introducing of the merely linguistic (syntactic) information into machine learning methods. Certain disadvantage is that previous ...

The Continuos Distance Transformation: a Generalization of the Distance Transformation for Continuos-valued Images

A feature extraction method for images is presented. It is based on the classical concept of Distance Transformation (DT) from which we develop a generalization, the Continuos Distance Transformation (CDT). Whereas the DT can only be applied to binary images, the CDT can be applied to both binary and gray-scale or color pictures. Furthermore, we define a number of new metrics and dissimilarity ...

Editorial Neointima Formation A Local Affair

Where do intimal smooth muscle cells (SMCs) come from? For many years, the idea that intimal SMCs originated from the underlying media went unchallenged.1 Then, reports2,3 began to appear that up to half of the SMCs in the intima of atherosclerotic plaques and injured arteries arose from circulating progenitor cells of bone marrow origin. This new view of intimal SMC formation was potentially i...

Sustainable case learning for continuos domains

Case-based reasoning (CBR) provides an adequate framework to cope with continuous domains, where a great amount of new valuable experiences are generated in a non-stop way. CBR systems become more competent in their evolution over time by means of learning new relevant experiences. There are two central problems derived from the continuous nature of some domains: the fast growing size of the ca...
