the aim of this study was to estimate suspended sediment by the ann model, dt with cart algorithm and different types of src, in ten stations from the lorestan province of iran. the results showed that the accuracy of ann with levenberg-marquardt back propagation algorithm is more than the two other models, especially in high discharges. comparison of different intervals in models showed that r...

In this research, we have compared three different attribute selection measures algorithms. We have used ID3 algorithm, C4.5 algorithm and CART algorithm. All these algorithms are decision tree based algorithm. We have got the accuracy of three different algorithms and we observed that the accuracy of ID3 algorithm is greater than C4.5 algorithm. But the accuracy of CART algorithm is greater th...

A significant interest for Web process design is to discover the discrepancies between the users' transaction process sequences and the desired process sequence for the Web transaction process. Sequence data analysis has been an important approach to analyzing Web log data in the e-commerce field. There have been many methods for sequence data analysis; however, few existing methods can be appl...

forest types mapping, is one of the most necessary elements in the forest management and silviculture treatments. traditional methods such as field surveys are almost time-consuming and cost-intensive. improvements in remote sensing data sources and classification –estimation methods are preparing new opportunities for obtaining more accurate forest biophysical attributes maps. this research co...

As more HIV patients start combination antiretroviral therapy (cART), the emergence of drug resistance (HIVDR) is inevitable. This will have consequences for transmission HIVDR, success ART, and nature trend epidemic. We recruited a cohort 223 starting or continuing their first-line cART in Tanzania towards end stavudine era 2010. Patients were then followed one year. Of those with viral load t...

The machine learning is a domain where machine performs intelligent works. To make a machine intelligent various technique and approaches are utilized, data mining is a subdomain of the machine learning. Data mining is an application by which machine automatically finds patterns over the input data, and using these estimated patterns data is recognized and patterns are classified. For that kind...
