Transformation problem

This book is mainly intended for designers and users of magnetic components in power electronics. It can also be used for didactical purposes. Magnetic components such as inductors and transformers constitute together with the control and the semiconductor components, the main parts in the design of power electronic converters. Some experience teaches that the design of the magnetic parts is still often done by trial and error. This can be explained by a (too) long workingin time for designing inductors and transformers.

The discrete wavelet transform (DWT) algorithms have a firm position in processing of signals in several areas of research and industry. As DWT provides both octavescale frequency and spatial timing of the analyzed signal, it is constantly used to solve and treat more and more advanced problems. The DWT algorithms were initially based on the compactly supported conjugate quadrature filters (CQFs). However, a drawback in CQFs is due to the nonlinear phase effects such as spatial dislocations in multiscale analysis.

DWTs are constantly used to solve and treat more and more advanced problems. The DWT algorithms were initially based on the compactly supported conjugate quadrature filters (CQFs). However, a drawback in CQFs is due to the nonlinear phase effects such as spatial dislocations in multiscale analysis. This is avoided in biorthogonal discrete wavelet transform (BDWT) algorithms, where the scaling and wavelet filters are symmetric and linear phase. The biorthogonal filters are usually constructed by a laddertype network called lifting scheme.

The publication of the CooleyTukey fast Fourier transform (FFT) algorithm in 1965 has opened a new area in digital signal processing by reducing the order of complexity of some crucial computational tasks like Fourier transform and convultion from N 2 to N log 2 , where N is the problem size. The development of the major algorithms (CooleyTukey and splitradix FFT, prime factor algorithm and Winograd fast Fourier transform) is reviewed. Then, an attempt is made to indicate the state of the art on the subject, showin the standing of researh, open problems and implementations....

Discrete Wavelet Transform is a wavelet (DWT) transform that is widely used in numerical and functional analysis. Its key advantage over more traditional transforms, such as the Fourier transform, lies in its ability to offer temporal resolution, i.e. it captures both frequency and location (or time) information.

In this paper, we address the problem of optimizing the style of textual content to make it more suitable to being listened to by a user as opposed to being read. We study the differences between the written style and the audio style by consulting the linguistics and journalism literatures. Guided by this study, we suggest a number of linguistic features to distinguish between the two styles.

An efﬁcient decoding algorithm is a crucial element of any statistical machine translation system. Some researchers have noted certain similarities between SMT decoding and the famous Traveling Salesman Problem; in particular (Knight, 1999) has shown that any TSP instance can be mapped to a subcase of a wordbased SMT model, demonstrating NPhardness of the decoding task. In this paper, we focus on the reverse mapping, showing that any phrasebased SMT decoding problem can be directly reformulated as a TSP.

For the task of recognizing dialogue acts, we are applying the TransformationBased Learning (TBL) machine learning algorithm. To circumvent a sparse data problem, we extract values of wellmotivated features of utterances, such as speaker direction, punctuation marks, and a new feature, called dialogue act cues, which we find to be more effective than cue phrases and word ngrams in practice.

The problem of transforming a lattice into a nondeterministic finite state automaton is nontrivial. We present a transformation algorithm which tracks, for each node of an automaton under construction, the larcs which it reflects and the lattice nodes at their origins and extremities. An extension of the algorithm permits the inclusion of null, or epsilon, arcs in the output automaton. The algorithm has been successfully applied to lattices derived from dictionaries, i.e. very large corpora of strings. ...

String transformation systems have been introduced in (Brill, 1995) and have several applications in natural language processing. In this work we consider the computational problem of automatically learning from a given corpus the set of transformations presenting the best evidence. We introduce an original data structure and efficient algorithms that learn some families of transformations that are relevant for partofspeech tagging and phonological rule systems.

The time has come when wellorganized and thoroughly worked out transfer grammars should be developed. Such a grammar should be composed of formal statements equating the constructiontypes of the input language with those of the output language and indicating the appropriate transformations which must be made to produce the target language constructions.

This paper addresses the search problem in textual inference, where systems need to infer one piece of text from another. A prominent approach to this task is attempts to transform one text into the other through a sequence of inferencepreserving transformations, a.k.a. a proof, while estimating the proof’s validity.

This paper addresses a problem that may arise in c]assificatzon tasks: the design of procedures for matching an instance with a set ~f criteria for class membership in such a way as to permit the intelligent handling ~f inexact, as well as exact matches. An inexact match is a comparlson between an instance and a set of criteria (or a second instance) which has the result that some, but not all, of the criteria described (or exemplified) in the second are found to be satisfied in the first. An exact match is such a comparison for which all of...

Throughout this book, the terms telemarketing and telesales are used interchangeably. However, some people define telemarketing as the use of the telephone to make contact with prospects, whereas telesales involves actually moving the pros pect further down the sales cycle or sales pipeline. The skills required of a telemarketer and/or telesales professional, as you’ll soon see, are identical....
