One of the major challenges for spoken document retrieval is how to handle speech recognition errors within the target documents. Query expansion is promising for this challenge. In this paper, we apply relevance models, a type of query expansion method, for the spoken document passage retrieval task. We adapted the original relevance model for passage retrieval. We also extended it to benefit ...

Quality and intelligibility of narrowband telephone speech can be improved by artificial bandwidth expansion (ABE), which expands the speech bandwidth using only information available in the narrowband speech signal. This paper describes an ABE method that generates a high-band expansion using spectral folding and then modifies the magnitude spectrum of the expansion band with spline curves. Th...

Recent work on neutrino propagation in stochastic media and its implications for the Sun and corecollapse supernovae are reviewed. It is shown that recent results from Sudbury Neutrino Observatory and SuperKamiokande combined with a best global fit value of δm2 = 5× 10−5 eV2 and tan2 θ = 0.3 rule out solar electron density fluctuations of a few percent or more. It is argued that solar neutrino ...

We present a language independent, unsupervised method for building word embeddings using morphological expansion of text. Our model handles the problem of data sparsity and yields improved word embeddings by relying on training word embeddings on artificially generated sentences. We evaluate our method using small sized training sets on eleven test sets for the word similarity task across seve...

The quantization of the bosonic string in a general curved space-time has been the subject of intensive research for some time [1, 2, 3, 4]. Whereas the treatment by de Vega [1] relies on the canonical quantization, only few attempts of a path integral quantization have been made. Those attempts [3, 4] involved the semi-classical approximation, but despite their conceptual simplicity no attempt...

We present measurements of D--> KS0 pi and D--> KL0 pi branching fractions using 281 pb(-1) of psi(3770) data at the CLEO-c experiment. We find that B(D0--> KS0 pi 0) is larger than B(D0--> KL0 pi 0), with an asymmetry of R(D0)=0.108+/-0.025+/-0.024. For B(D+--> KS0 pi+) and B(D+--> KL0 pi+), we observe no measurable difference; the asymmetry is R(D+)=0.022+/-0.016+/-0.018. The D0 asymmetry is ...

In this paper, we propose a numerical method based on the generalized hat functions (GHFs) and improved hat functions (IHFs) to find numerical solutions for stochastic Volterra-Fredholm integral equation. To do so, all known and unknown functions are expanded in terms of basic functions and replaced in the original equation. The operational matrices of both basic functions are calculated and em...

A bstract We calculate the fully differential medium-induced radiative spectrum at next-to-leading order (NLO) accuracy within Improved Opacity Expansion (IOE) framework. This scheme allows us to gain analytical control of low and high gluon frequencies simultaneously. The frequency regime can be obtained in standard opacity expansion framework which resulting power series diverges characterist...
