Histogram Equalization-Based Features for Speech, Music, and Song Discrimination

Ascensión Gallardo-Antolin, Juan M Montero
2010 IEEE Signal Processing Letters  
These features, called PHEQ (Polynomial-Fit Histogram Equalization), are derived from the nonlinear relationship between the short-term feature distributions computed at segment level and a reference distribution  ...  In this letter, we present a new class of segment-based features for speech, music and song discrimination.  ...  HISTOGRAM EQUALIZATION-BASED SEGMENTAL FEATURES FOR AUDIO CLASSIFICATION The proposed segment-based features, called PHEQ (Polynomial-Fit Histogram Equalization), consist of a set of parameters derived  ...

Transformed Tree-Structured Regression Method

Gloria Gheno
2016 Bulletin of Mathematical Sciences and Applications  
My simulation results show that my method with regression tree is better than the tree-based regression methods proposed in literature because it understands the true relationship between the regressors  ...  Many times the response variable is linked linearly to the function of the regressors and to the error term through its function g(Y).  ...  Then in these cases, the traditional tree-based methods underestimate the ratio H most respect to the TTRS methods giving more importance to the error term.  ...

Translating and Searching Service Descriptions Using Ontologies [chapter]

Daniela Damm, Farshad Hakimpour, Andreas Geppert
2003 Lecture Notes in Computer Science  
Ontologies are related on the basis of similarity relations in order to translate between elements of different service descriptions.  ...  In this paper, we present an approach to facilitate the search for services, where services and requests can be described using heterogeneous standards.  ...  Disjoint elements in S are included to trans S-T in the same way (e.g., Include ebXML ). • Equal or specialization: In case a term s in S is equal to or specializes a term t in T, we copy the whole subtree  ...

Novel approach to a rule-based general purpose program translator using paramodulation

Yoshiyasu Takefuji, Michael Dowell
1988 Knowledge-Based Systems  
In this paper a rule-based Lisp dialect translator using paramodulation is presented as an example of a general purpose program translator application where the knowledge about the translation is embedded  ...  The advantage of using a rule-based system is to allow the user to supply his own rules for translation, thus the translator can be considered as a general purpose converter.  ...  In the above example, one would say that paramodulation occurred from the term a into the term b 2.  ...

Evolution of a teaching approach for beginning algebra

Rakhi Banerjee, K. Subramaniam
2011 Educational Studies in Mathematics  
The teaching approach emphasized the structural similarity between arithmetic and algebraic expressions and aimed at supporting students in making a transition from arithmetic to beginning algebra.  ...  Analysis of students' written and interview responses as the approach evolved revealed the potential of the approach in creating meaning for symbolic transformations in the context of both arithmetic and  ...  In the more refined teaching approach used in MST-II, we used the concepts 'term', 'equality' and 'expression' and the operation 'combining terms' in order to establish the connection between procedure  ...

Analysis/Synthesis filter bank design based on time domain aliasing cancellation

J. Princen, A. Bradley
1986 IEEE Transactions on Acoustics Speech and Signal Processing  
The technique is developed in terms of a weighted overlap-add method of analysis/synthesis and allows overlap between adjacent time windows.  ...  In fact, a duality exists between the new technique and the frequency domain techniques of [7] and 181.  ...  ACKNOWLEDGMENT The authors would like to thank A. Johnson for his helpful comments, and also the reviewers, whose suggestions contributed significantly to the quality of the final manuscript.  ...

On unbiased backtransform of lognormal kriging estimates

Jorge Kazuo Yamamoto
2007 Computational Geosciences  
This technique takes advantage of a logarithmic transformation that reduces the data variance.  ...  However, backtransformed lognormal kriging estimates are biased because the nonbias term is totally dependent on a semivariogram model.  ...  The author is grateful to an anonymous reviewer for comments and suggestions that improved this manuscript.  ...

Matrix tensor notation part I. Rectilinear orthogonal coordinates

W.C. Hassenpflug
1993 Computers and Mathematics with Applications  
This is achieved by the introduction of the base as a tensor quantity in the fundamental equation for the relation between a tensor and its representation as a matrix.  ...  It is also shown that the same notation is equally useful for vectors in abstract higher dimensional space and transformations and transforms in function space.  ...  In matrix tensor notation --Ta --Ta --d E -a =E, -E, (67) is the mixed base unit tensor equal to gij, and the transformation between column and row vectors in nonorthonormal base in matrix tensor notation  ...

Histogram Equilization on Wavelet based Compression Techniques

Sandeep Dalal, Poonam Rani
2014 International Journal of Computer Applications  
This paper analyzes the effect of histogram equalization on the wavelet based compression techniques. Image compression is reducing the size of an image using one of the encoding techniques.  ...  Encoding helps in saving disk space by representing the same data in lesser number of bytes. Histogram is a graphical representation of intensity distribution of an image.  ...  To make it simple, what histogram equalization technique does is that, it changes the pdf of a given image into that of a uniform pdf that spreads out from the lowest pixel value (0 in this case) to the  ...
