With each algorithm, we provide a description of the algorithm … The new values are used to create a better guess for the first set, and the process continues until the algorithm converges on a fixed point. The theorem of Bayes provides a way of calculating the posterior probability, P(c|x), from P(c), P(x), and P(x|c). C4.5 is used to generate a classifier in the form of a decision tree from a set of data that has already been classified. The Artificial Neural Network (ANN) bases its assimilation of data on the way that the human brain processes information. Classifier here refers to a data mining tool that takes data that we need to classify and tries to predict the class of new data. Typically, users expect a search query to complete in a short time (such as a few hundred milliseconds for web search), which makes it impossible to evaluate a complex ranking model on each document in the corpus, and so a two-phase scheme is used. Data mining can unintentionally be misused, and can then produce results that appear to be significant; but which do not actually predict future behavior and cannot be reproduced on a new sample of data and bear little use. That the entropy of attribute. C4.5 is one of the best data mining algorithms and was developed by Ross Quinlan. Data mining is the process of finding patterns and repetitions in large datasets and is a field of computer science. Since kNN is given a labelled training dataset, it is treated as a supervised learning algorithm. Finally, result (output) units are the end part of the process; this is where the network responds to the data that was put in initially and can now be processed.
