The problem of estimating the parameters which determine a mixture density has been the subject of a large, diverse body of literature spanning nearly ninety years. During the last two decades, the...

Thank you for downloading combining pattern classifiers methods and algorithms. Maybe you have knowledge that, people have look hundreds times for their chosen novels like this combining pattern classifiers methods and algorithms, but end up in infectious downloads. Rather than enjoying a good book with a cup of coffee in the afternoon, instead they cope with some harmful virus inside their computer.

Feature extraction methods for character recognition--a survey

The binary feature vector is one of the most common representations of patterns and measuring similarity and distance measures play a critical role in many problems such as clustering, classification, etc. Ever since Jaccard proposed a similarity measure to classify ecological species in 1901, numerous binary similarity and distance measures have been proposed in various fields. Applying appropriate measures results in more accurate data analysis. Notwithstanding, few comprehensive surveys on binary measures have been conducted. Hence we collected 76 binary similarity and distance measures used over the last century and reveal their correlations through the hierarchical clustering technique.

A Survey of Binary Similarity and Distance Measures

A note on binary template matching

Previous publications combining the properties of multiple soil orders show that depth to carbonate (DTC) increases systematically between 350 and 1000 mm of mean annual precipitation (MAP). We hypothesize that carbonate in Vertisols (clay‐rich, shrink‐swell soils) respond differently to water flux than other soil orders because of lower permeability. To test this hypothesis, we compiled soil description and characterization data from multiple published sources across a late Pleistocene climosequence of the coast prairie of Texas to assess the relationship between MAP (700–1400 mm) and DTC. The DTC of carbonate nodules represents an index of accumulation and the DTC of calcium carbonate equivalent (total carbonate <2.0 mm diam.) an index of leaching. The DTC for 1%, 2%, and 5% abundances were assessed using regression analysis. The R2 values were highest for the DTC of 2% nodules and of 1% calcium carbonate equivalent in Vertisol microlows. Surprisingly, relatively high R2 values were calculated ...

Vertisol Carbonate Properties in Relation to Mean Annual Precipitation: Implications for Paleoprecipitation Estimates

Quality of life assessments were used in this study to determine the behavioral changes of children diagnosed with autism spectrum disorder (ASD) who participated in equine assisted activities. Behavioral changes of children with ASD participating in 9 weeks of equines assisted activities (EAA) (N = 10) were compared to behavioral changes of children who participated in a non-equine intervention (N = 8). Parents noted significant improvements in their child’s physical, emotional and social functioning following the first 6 weeks of EAA. The children participating in the non-equine program also demonstrated improvement in behavior, but to a lesser degree. The favorable outcome of this study lends support for continuation of programs utilizing EAA in the treatment of children with ASD.
