In this work, a Genetic Algorithm boosted Least Square Support Vector Machine model by a set of linear equations instead of a quadratic program, which is improved version of Support Vector Machine model, was used for estimation of 98 pure compounds second virial coefficient. Compounds were classified to the different groups. Finest parameters were obtained by Genetic Algorithm method ...

داده کاوی یکی از شاخه های مطرح علمی است که در سالهای اخیر توسعه فراوانی یافته است. بنابر گزارش دانشگاه mit، دانش نوین داده کاوی یکی از ده دانش در حال توسعه ای است که دهه آینده را با انقلاب تکنولوژیکی مواجه می سازد. دسته بندی داده ها، از مهمترین مباحث مطرح در داده کاوی است. در خصوص دسته-بندی داده ها روش های گوناگونی ارائه گردیده است که ماشین بردار پشتیبان(svm) از مهمترین آنها است و از آنجایی که ...

     In this research, we used the support vector machine (SVM), support vector machine combine with wavelet transform (W-SVM), ARMAX and ARIMA models to predict the monthly values of precipitation. The study considers monthly time series data for precipitation stations located in Hamedan province during a 25-year period (1998-2016). The 25-year simulation period was divided into 17 years for t...

Fault diagnosis has always been an essential aspect of control system design. This is necessary due to the growing demand for increased performance and safety of industrial systems is discussed. Support vector machine classifier is a new technique based on statistical learning theory and is designed to reduce structural bias. Support vector machine classification in many applications in v...
