We present a study on approaches to handle variation in a deep natural language processing formalism. It allows a grammar to be parameterized as to what language variants it accepts, but also to detect such variants. In this respect, we compare it to standard language identification methods, employed here to detect variation in the same language.
To deepen our understanding of object recognition, it is critical to understand the nature of transformations that occur in intermediate stages of processing in the ventral visual pathway, such as area V4. Neurons in V4 are selective to local features of global shape, such as extended contours. Previously, we found that V4 neurons selective for curved elements exhibit a high degree of spatial v...
BACKGROUND Dopamine plays an important role in orienting, response anticipation and movement evaluation. Thus, we examined the influence of functional variants related to dopamine inactivation in the dopamine transporter (DAT1) and catechol-O-methyltransferase genes (COMT) on the time-course of motor processing in a contingent negative variation (CNV) task. METHODS 64-channel EEG recordings w...
For evaluation of Iranian onion morphotypes potentials and application of them in breedingprogrames, seeds of 23 Iranian onion morphotypeswere collected from East Azarbaijan (RedAzarshahrmorphotypes), Tehran (Red Rey morphotypes), Razavi Khorasan (Red Neyshaboormorphotypes) and Zanjan (Gholyghese morphotypes). These onion morphotypes were planted inRCBD design in four replications in Seed and P...
Special properties of Iranian wool such as elasticity compared with Merino wool leads to more popularity of Persian carpet at an international level. By using of finishing process it is possible to improve some of the physical properties of wool fibers such as fleece modification, increasing of lightness and whiteness and producing a smoother surface that result a better quality carpet. In this...
High-pressure torsion (HPT) is a metal processing method in which the sample is subjected to a very high plastic shear deformation. This process can produce exceptional levels of grain refinement, and provides a corresponding improvement in mechanical properties. To investigate the stress and strain distribution due to HPT process finite element simulation were conducted to investigate effectiv...
The area that contains studied gemstones is located in 19 km South of Torud and 135 kilometer Southeast of Damghan. The quickest and most cost-effective processing method for gemstones in this area is using grind discs in the abrasion and forming stage with the 120 mesh and dry method in polishing stage. The concentration of iron oxide and the presence of calcite and clay minerals made the vari...
This paper deals with the problem of face recognition from a single image per person by producing virtual images using neural networks. To this aim, the person and variation information are separated and the associated manifolds are estimated using a nonlinear neural information processing model. For increasing the number of training samples in neural classifier, virtual images are produced for...
An intelligent strategy for the protection of AC microgrids is presented in this paper. This method was halving to an initial signal processing step and a machine learning-based forecasting step. The initial stage investigates currents and voltages with a window-based approach based on the dynamic decomposition method (DDM) and then involves the norms of the signals to the resultant DDM data. T...
Wheat (Triticum aestivum L.) is known to be the world-leading cereal grain and the most important food in the world of agriculture. Wheat offers a great wealth of material for genetic studies due to its wide ecological distribution and host of variation for various morphological and physiological characters. To evaluate the genetic control of physical traits of grain in two crosses of winter ...
