Among the symmetrical structures the replication protein binding sites have been identified as well as sites taking part in the transcription initiation. The results obtained show the efficiency of symmetrical analysis in solving the problem of pattern recognition in genetic text.","PeriodicalId":289764,"journal":{"name":"Proceedings.

In the first part a direct inverse control scheme is presented for controlling a DC motor, which is based on a clustering neural network, called the progressive learning network (PLN) because of its inherent capacity of learning online. This approach can control the whole system without having to use a very rich training set; moreover it is able to adapt itself online to new working conditions by varying the number of neurons. In the second part of the paper some applications of self-organising neural networks are described for the diagnosis of AC drives. In particular it is shown that the vector quantisation projection algorithm can be useful for diagnosis purposes since it permits an easier representation of the output space than that available with the Kohonen's map.","PeriodicalId":289764,"journal":{"name":"Proceedings.

Both the median and mean filters are popular smoothing methods, but there can be problems when these two filters are applied to an image corrupted by unknown noise.

The aim of our probability filter is to provide a compromise between the two more conventional filters. We present experimental results and performance evaluation of the median, mean filters and this probability filter operating on an image corrupted by impulse-like or random noise.","PeriodicalId":289764,"journal":{"name":"Proceedings.

The fuzzy ARTMAP classifier transfers after ART resonance, the choice function of all eligible nodes to a single layer perceptron (SLP) defuzzifier. There, the fuzzy scores are mapped to the a-posteriori probabilities of visiting CHMM states. Lower computing time results from estimating observation probabilities with such local error propagation NN, than with well-known multilayer perceptron. The fuzzy ARTMAP NN determines inherent discrimination among generated probabilities, discrimination usually added into HMM training by using the complex MMIE algorithm. Iterative training has been used to instruct the fuzzy ARTMAP and the SLP defuzzifier. The CHMM component was not trained due to small changes of transition probabilities.","PeriodicalId":289764,"journal":{"name":"Proceedings.

The secondary structure of an RNA is a set of base-pairs (nucleotide pairs) which formed bonds between A-U and C-G. These bonds have been traditional assumed to be non-crossing in the secondary structure. This implies a tree representation of the secondary structure of RNA molecule. This paper considers several notions of similarity between two RNA molecule structures taking into account both the primary and the secondary structures. We consider a natural tree representation with both primary and secondary structure data. We present efficient algorithms for comparing such tree representation. We then show that some of these similarity notions can be used to solve the structure prediction problem when the structure of a closely related RNA is known.","PeriodicalId":289764,"journal":{"name":"Proceedings.

Issues in text-to-speech synthesis 文本到语音合成中的问题

Macchi","doi":"10.1109/IJSIS.1998.685467","DOIUrl":"https://doi.org/10.1109/IJSIS.1998.685467","url":null,"abstract":"The ultimate goal of text-to-speech synthesis is to convert ordinary orthographic text into an acoustic signal that is indistinguishable from human speech. Originally, synthesis systems were architected around a system of rules and models that were based on research on human language and speech production and perception processes. The quality of speech produced by such systems is inherently limited by the quality of the rules and the models. Given that our knowledge of human speech processes is still incomplete, the quality of text-to-speech is far from natural-sounding. Hence, today's interest in high quality speech for applications, in combination with advances in computer resource, has caused the focus to shift from rules and model-based methods to corpus-based methods that presumably bypass rules and models. For example, many systems now rely on large word pronunciation dictionaries instead of letter-to-phoneme rules and large prerecorded sound inventories instead of rules predicting the acoustic correlates of phonemes. Because of the need to analyze large amounts of data, this approach relies on automated techniques such as those used in automatic speech recognition.","PeriodicalId":289764,"journal":{"name":"Proceedings.

The method makes the structured light based detection system more robust and applicable to use outdoors as aid for navigation. The method differentiates between the structured light produced by a light stripe projector and the light stripe kind patterns caused by ambient illumination. The centre of gravity of the segmented light stripe is tracked by using a Kalman filter. The position information together with the other properties of the stripe segment, including intensity, length and orientation are used to identify the same light stripe segment in adjacent images. By using a pulsed light source it is possible to differentiate between true and false light stripes depending on their time of appearance. During the project, a working obstacle detection system for a partly structured outdoor environment was implemented.","PeriodicalId":289764,"journal":{"name":"Proceedings.
