Combinatory Category Grammar (CCG) supertagging is a task to assign lexical categories to each word in a sentence. Almost all previous methods use fixed context window sizes to encode input tokens. However, it is obvious that different tags usually rely on different context window sizes. This motivates us to build a supertagger with a dynamic window approach, which can be treated as an attentio...

In this paper, we present various functional means in the sense of convex analysis. In particular, a logarithmic mean involving convex functionals, extending the scalar one, is introduced. In the quadratic case, our functional approach implies immediately that of positive operators. Some examples, illustrating theoretical results and showing the interest of our functional approach, are discussed.

In studies concerning driver state, particularly attention loss and driver drowsiness, a phenomenon can be observed which we refer to as driving without awareness (DWA). The purpose of the study presented here is to learn more about the underlying characteristics of this symptom of driver drowsiness that occurs if the will to keep one’s eyes open overrides the physiolo gical need of a drowsy pe...

Conventional compilers often are large entities that are highly complex, di cult to maintain and hard to reuse. In this article it is argued that this is due to the inherently functional approach to compiler construction. An alternative approach to compiler construction is proposed, based on object-oriented principles, which solves (or at least lessens) the problems of compiler construction. Th...

This article presents an analytic approach to study admissibility conditions related to classical full wavelet systems over finite fields using tools from computational harmonic analysis and theoretical linear algebra. It is shown that for a large class of non-zero window signals (wavelets), the generated classical full wavelet systems constitute a frame whose canonical dual are classical full ...

introduction: poor sensitivity and poor signal to noise ratio because of low injected thallium dose and presence of scattered photons are the main problems in using thallium in scintigraphic imaging of the heart. scattered photons are the main cause of degrading the contrast and resolution in spect imaging that result in error in quantification. thallium decay is very complicated and photons ar...

Good daylighting design in buildings not only provides a comfortable luminous environment, but also delivers energy savings and comfortable and healthy environments for building occupants. The importance of using daylight in educational buildings is because of the synchrony of operating hours of the school and daylight plenitude the sky. Daylight improves environmental quality and saves energy ...

Texture defect detection methods are used for quality control purposes. Inspection systems fullfilling this task should be able to determine the necessary parameter sets automatically in case of a task change. One of these parameters is the size of the image window from which texture features are calculated. We present an approach for the calculation of an appropriate window size for statistica...

Paying attention to the health of people in the community is one of the main challenges that has received much attention in recent years. Regarding the importance of the healthcare sector in the life of the community, evaluation of the performance of this sector is important. One of the most practical methods for evaluating performance is the use of data envelopment analysis approach. In this p...
