The present paper addresses the question of the efficiency of Independent Component Analysis (ICA) as a statistical process for deriving optimal representational bases for the projection of spectrum and cepstrum in the context of Automatic Speech Recognition (ASR). Several decorrelation strategies have been applied on the log-spectrum and cepstrum to fulfill the practical need of a diagonal cov...

Recent story completion studies (Arnold 2001, Rohde et al. 2006) show that passages exhibiting different coherence relations yield different patterns of pronoun interpretation. These results predict that a shift in the distribution of coherence relations in participant responses ought to induce a shift in the distribution of pronoun interpretations. Experiment 1 manipulates the coherence distri...

The present study aimed to review the instruction of the L2 speech acts in English pragmatics in the Iranian context during the last two decades from 2000 to 2020. To this end, upon the completion of the study search, the retrieved articles were selected and analyzed based on the research domain.  The results of our synthesis from 54 studies carried out on the instruction of the speech act not ...

How can we describe and transmit the whole visual data at a distant place? In order to answer such a question, the authors have proposed the concept of the “Space Coding” and examined a DCT-based method to compress real ray data. This paper discusses the application of this method to realize walking through the photo-realistic virtual world. Thanks to the random accessibility of the DCT-based m...

H.264 [1] and AVS [2] are the emerging state-of-art video coding standards, in which the block-based hybrid coding framework is employed. DCT or its approximation such as Integer Cosine Transform (ICT) is the centerpiece for signal decorrelation and energy compaction. After DCT, the transform coefficients are quantized and scanned into one-dimensional (1-D) signals, named run-level pairs. The k...

BACKGROUND Intraocular pressure (IOP) measurements using Goldmann applanation tonometry (GAT) are influenced by central corneal thickness (CCT) whereas dynamic contour tonometry (DCT) allows for IOP measurements independent of CCT. After Descemet's stripping automated endothelial keratoplasty (DSAEK) the CCT is, compared to healthy eyes, increased. The objective of this prospective study was to...

In single utterance understanding, which does not include discourse understanding, the concept error rate (CER), or the keyword error rate, has been widely used as an evaluation measure for utterance understanding. However, the CER cannot be used for evaluating systems that understand user utterances based on previous user utterances. In this paper, we propose a method for evaluating incrementa...

Motivated by the recent effort on scenario-based context question answering (QA), this paper investigates the role of discourse processing and its implication on query expansion for a sequence of questions. Our view is that a question sequence is not random, but rather follows a coherent manner to serve some information goals. Therefore, this sequence of questions can be considered as a mini di...
