· Trading off false positive rates against false negative rates. Another way to tackle the problem of classifier design is to frankly admit that we have two competing objectives, and try to balance them. One objective is to have low false positive rates, and the other objective is to have low false negative rates.
contact usSoil classification system means, for the purpose of this subpart, a method of categorizing soil and rock deposits in a hierarchy of Stable Rock, Type A, Type B, and Type C, in decreasing order of stability. The categories are determined based on an analysis of the properties and performance characteristics of the deposits and the environmental ...

These precipitates make stream substrates less hospitable to aquatic insects, thus reducing their numbers. In addition, the limestone sand that collects on the stream bottom fills ...

The sand production prediction is one of the long-standing and complex problems in the petroleum industry om the phenomenological viewpoint, sand production can occur when the formation do not present sufficient strength to withstand destabilizing forces generated during the flow of reservoir fluid,, .A wide variety of problems such as production loss due to plugging the ...
contact us· In the family of learning classifier systems, the classifier system XCS has been successfully used for many applications. However, the standard XCS has no memory mechanism and can only learn optimal policy in Markov environments, but fails in non-Markov ones. In this work, we aim to develop a new classifier system based on XCS to tackle this problem.
contact usThe necessity of classification is highly demanded in real life. As a mathematical classification approach, the Naive Bayes classifier involves a series of probabilistic computations for the purpose of finding the best-fitted classification for a given piece of data within a problem domain. In this paper, an implementation of Naive Bayes classifier is described. This classifier can be used as ...
contact us· The problem of quantification is closely related to classification in that the quantifier''s task is to estimate the number of instances of each class in a sample. In fact, a common approach, known as classify-then-count, is to first classify a set of instances and then count the labels.

contact us6.2.1 Framing the optimization problem in terms of our classifier I''ve talked about the classifier but haven''t mentioned how it works. Under-standing how the classifier works will help you to understand the optimization problem. We''ll have a simple equation like the sigmoid where we can enter our data values and get a class label out.
