Abstract:
The present invention relates to a filter bank approach to adaptive filtering method using independent component analysis. More particularly, the invention relates to a method of improving the performance of adaptive filtering method by applying independent component analysis that is capable of reflecting the secondary or even higher order statistical characteristics to adaptive filtering algorithm using the filter bank approach.In order to implement the conventional adaptive filter algorithm using independent component analysis to the real world problem, a large number of filter training coefficients are required and also a large amount of calculation is required when a training is undertaken. This results in a very slow learning speed and the deterioration in the quality of result signals.The adaptive filtering method using independent component analysis according to the present invention provides a method of reducing the large amount of calculation required for filter training, improving the learning speed and the quality of result signals by utilizing a filter bank approach.Hence, the filter bank approach to adaptive filtering method using independent component analysis according to the present invention is capable of improving the performance over the conventional adaptive filtering method using independent component analysis.
Abstract:
The present invention considers a method for active cancellation using independent component analysis. More particularly, the present invention relates to a method which is operable the independent component analysis technique to an adaptive algorithm that can consider secondary or more higher statistical characteristics.The conventional active noise cancellation systems mainly use the LMS(Least Mean Square) which considers secondary statistics among input signals.Being different from the conventional active noise cancellation systems, the present invention provides a method for active noise cancellation using independent component analysis, which makes output signals independent of each other by considering secondary or more higher statistical characteristics.Therefore, according to the present invention, the improved performances of the noise cancellation systems can be provided compared with the conventional active noise cancellation system which uses the LMS adaptive algorithm.

Abstract:
The present invention discloses an implementation of the selective attention mechanism occurring in the human brain using a conventional neural network, multi-layer perceptron and the error back-propagation method as a conventional learning method, and an application of the selective attention mechanism to perception of patterns such as voices or characters. In contrast to the conventional multi-layer perceptron and error back-propagation method in which the weighted value of the network is changed based on a given input signal, the selective attention algorithm of the present invention involves learning a present input pattern to minimize the error of the output layer with the weighted value set to a fixed value, so that the network can receive only a desired input signal to simulate the selective attention mechanism in the aspect of the biology. The present invention also used the selective attention algorithm to define the degree of attention to a plurality of candidate classes as a new criterion for perception, thus providing high perception performance relative to the conventional recognition system for a single candidate class.
Abstract:
The present invention relates to a pharmaceutical composition for preventing or treating diseases related to abnormal proliferation of cells, comprising a cytoplasmic heat shock protein (Hsp)60 kDa inhibitor as an active ingredient, and to a screening method and a kit using the composition. According to the present invention, substances which inhibit expression of cytoplasmic Hsp 60 genes or inhibit activity of cytoplasmic Hsp 60 or inhibit binding between cytoplasmic Hsp 60 and IKK protein prevent interaction between cytoplasmic Hsp 60 and IKK complexes to make NF-κB path inactive, and thus induce apoptosis. Therefore, the substances can be valuably used in preventing or treating diseases related to abnormal proliferation of cells, such as cancer, inflammatory diseases or hyperproliferative vascular diseases.

Abstract:
An apparatus for extracting a signal from convolutive mixtures includes a receiving unit which includes two or more receivers and receives a signal; a transfer function calculation unit which calculates transfer functions for demixing; and a demixing unit which demixes the received signal using the calculated transfer functions. The transfer function is determined such that a signal is extracted from a source closest to the receivers, and is calculated on the basis of a transfer function for a path to each receiver being approximated to a delta function as closer to the source.
