Detection of a brain tumor due to their intricacy, the irregularity formations, and variety tissue textures forms, gliomas pro- vide difficult problem for medical image interpretation. Machine learning- based approaches semantic segmentation have consistently surpassed ear- lier techniques in this challenge. However some learn- ing are unable deliver necessary local information associated chang...

Abstract Hand-crafted point descriptors have been traditionally used for visual loop closure detection. However, in low-textured environments, it is usually difficult to find enough features and, hence, the performance of such algorithms degrade. Under this context, paper proposes a detection method that combines lines and learned points work, particularly, scenarios where hand-crafted fail. To...

In this paper we introduce our system participating at the 2017 SemEval shared task on keyphrase extraction from scientific documents. We aimed at the creation of a keyphrase extraction approach which relies on as little external resources as possible. Without applying any hand-crafted external resources, and only utilizing a transformed version of word embeddings trained at Wikipedia, our prop...

This article focuses on tools that allow amateurs to create or modify videogames. In order to contribute to study the nature of game design, we will analyze games as crafted “artifacts”. We will first review five categories of tools that allow creating games, in order to highlight the different “parts” games are made of. We will then use this empirical review to introduce a simple model of the ...

We present a novel approach to metaphor interpretation and a system that produces literal paraphrases for metaphorical expressions. Such a representation is directly transferable to other applications that can benefit from a metaphor processing component. Our method is distinguished from the previous work in that it does not rely on any hand-crafted knowledge about metaphor, but in contrast emp...

This article reports on a workshop held to explore the potential uses of operational earthquake forecasting (OEF). We discuss the current status of OEF in the United States and elsewhere, the types of products that could be generated, the various potential users and uses of OEF, and the need for carefully crafted communication protocols. Although operationalization challenges remain, there was ...

Pattern recognition systems have been increasingly used in security applications, although it is known that carefully crafted attacks can compromise their security. We advocate that simulating a proactive arms race is crucial to identify the most relevant vulnerabilities of pattern recognition systems, and to develop countermeasures in advance, thus improving system security. We summarize a fra...

Experience has shown that a crafted combination of concepts of different metaheuristics can result in robust combinatorial optimization schemes and produce higher solution quality than the individual metaheuristics themselves, especially when solving difficult real-world combinatorial optimization problems. This chapter gives an overview of different ways to hybridize GRASP (Greedy Randomized A...

Pervasive computing in mobile ad hoc networks requires that applications react to a plethora of events fired by other devices in the mobile ad hoc network. Current context-aware and event-driven architectures require the programmer to react to these events via a carefully crafted network of observers and event handlers, while inherently introducing complex concurrency issues. This paper propose...
