A Nonparametric Approach for Active Contours

2007 International Joint Conference on Neural Networks, 2007
Active contours are commonly used in many image segmentation applications. There are different active contour definitions, but all active contour definitions in the literature use parametric forms to determine the shape priors or adjust the weighting of internal and external forces acting on the active contour.

An approach for profiling phishing activities

Computers & Security, 2014
Phishing attacks continue unabated to plague Internet users and trick them into providing personal and confidential information to phishers. In this paper, an approach for email-born phishing detection based on profiling and clustering techniques is proposed.

Ancillary approaches to plasminogen activators

Annals of the New York Academy of Sciences, 2012
Acute ischemic stroke develops from an interruption in focal cerebral blood flow. In many cases, it is caused by an acute thromboembolism. Although systemic fibrinolytic therapy for acute ischemic stroke has been a significant breakthrough in the management of this disease, additional agents and methods that could improve or restore cerebral flow are ...

An Approach to Semantics for UML Activities

2017
The precise semantics for UML Activities is must-have in automated applications of them. The paper proposes an approach to a definition of a semantics of a set of UML Activities in the form of LTS (Labelled Transition System). The set of activities is transformed to a graph of possible execution traces, using OCL (Object Constraint Language) operations.

Active learning for classification: An optimistic approach

2014 IEEE Symposium on Adaptive Dynamic Programming and Reinforcement Learning (ADPRL), 2014
In this paper, we propose to reformulate the active learning problem occurring in classification as a sequential decision making problem. We particularly focus on the problem of dynamically allocating a fixed budget of samples. This raises the problem of the trade off between exploration and exploitation which is traditionally addressed in the ...

Supporting and maintaining derivations: A declarative active approach active approach

1997
Derivations in object-oriented databases are supported currently by means of imperative methods or by using deductive or even active rules. As imperative languages are difficult to analyze in order to extract dependencies, derivations are never maintaine and attributes are calculated each time they are requested.

The Activity Approach: Death or Rebirth?

Russian Studies in Philosophy, 2001
In the not-too-distant past, the activity approach was quite popular in Russian philosophy and in many human sciences, including psychology. Recently it has come under criticism, even from some of its former proponents. This issue begins a series of articles devoted to assessing the results of research that has been conducted in Russia along the lines ...

A declarative approach to active databases

[1992] Eighth International Conference on Data Engineering, 2003
A general description is provided of the field of active databases, focusing on the main problems yet to be solved. The author suggests that deductive databases may contribute to the understanding of some of these problems. Classes of applications that can be specified in a declarative manner are indicated.
