discretization method, to entropy-based and purity-based methods, which are supervised algorithms. We found that the performance of the Naive-Bayes algorithm signi cantly improved when features were discretized using an entropy-based method. In fact, over the 16 tested datasets, the discretized version of Naive

approach to detect turns of a Gaussian process; the decision of a turn is based on the Bayesian Information Criterion (BIC), a model selection criterion well-known in the statistics literature. The BIC criterion can also be applied as a termination criterion in hierarchical methods for clustering of audio

applied the UCBI model to assess the uncertainty of purity measurements, and compared the results to those from conventional qualification. We demonstrated that the UBCI model is suitable to dynamically assess method performance characteristics, based on information extracted from individual chromatograms

. for different impurity groups. The effective methods of preparations and analysis of high- purity glasses are developed. The best glass samples con-tain the impurities of widespread metals and silicon on the level of 0.1 ppm wt., optically ac-tive hydrogen- 0.2-0.05 ppm at., oxygen and carbon- 0.5- 1 ppm wt

This paper addresses the problem of automatically grouping unknown speech utterances that are from the same speaker. A clustering method based on maximum purity estimation is proposed, with the aim of maximizing the similarities of voice characteristics between utterances within all the clusters

in image clustering. A system of X-ray coal image purity detection is developed and tested. According to the intensity distribution of X-ray images, an area of interest is selected based on Gaussian distribution property which greatly cut down the data to be processed. On the basis of that, particle swarm

Pixel Purity Index (PPI) has been widely used for endmember extraction. Recently, an approach using blocks of skewers was proposed by Theiler et al., called blocks of skewers (BOS) method, to improve computation of the PPI. It utilizes a block of skewers to reduce number of calculations of dot

Due to the strong nonlinearity and transition dynamics between different operating points of the high purity distillation column process, it is difficult to use a single model for modeling such a process. Therefore, the multiple model based approach is introduced for modeling the high purity

A novel method has been developed for the preparation of nearly pure separate cultures of astrocytes and oligodendrocytes. The method is based on (a) the absence of viable neurons in cultures prepared from postnatal rat cerebra, (b) the stratification of astrocytes and oligodendrocytes in culture

High-throughput instant quantification of protein expression and purity based on photoactive yellow protein turn off/on label
