background: we aimed to assess the high-risk group for suicide using different classification methods includinglogistic regression (lr), decision tree (dt), artificial neural network (ann), and support vector machine (svm). methods: we used the dataset of a study conducted to predict risk factors of completed suicide in hamadan province, the west of iran, in 2010. to evaluate the high-risk grou...
support vector regression (svr) solves regression problems based on the concept of support vector machine (svm). in this paper, a new model of svr with probabilistic constraints is proposed that any of output data and bias are considered the random variables with uniform probability functions. using the new proposed method, the optimal hyperplane regression can be obtained by solving a quadrati...
klinkenberg permeability is an important parameter in tight gas reservoirs. there are conventional methods for determining it, but these methods depend on core permeability. cores are few in number, but well logs are usually accessible for all wells and provide continuous information. in this regard, regression methods have been used to achieve reliable relations between log readings and klinke...
a robust and reliable quantitative structure-property relationship (qspr) study was established to forecast the melting points (mps) of a diverse and long set including 250 drug-like compounds. based on the calculated descriptors by dragon software package, to detect homogeneities and to split the whole dataset into training and test sets, a principal component analysis (pca) approach was used...

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 ...
this paper aims to assess the application of support vector machine (svm) regression in order to analysis flexible pavements. to this end, 10000 four-layer flexible pavement sections consisted of asphalt concrete layer, granular base layer, granular subbase layer, and subgrade soil were analyzed under the effect of standard axle loading using multi-layered elastic theory and pavement critical r...
this paper is concerned with the development of a novel classifier for automatic mass detection of mammograms, based on contourlet feature extraction in conjunction with statistical and fuzzy classifiers. in this method, mammograms are segmented into regions of interest (roi) in order to extract features including geometrical and contourlet coefficients. the extracted features benefit from...
در این پایان نامه یک شبکه عصبیltrfootnote{neural network} تک لایه بازگشتی برای ماشین بردار پشتیبانیltrfootnote{support vector machine} (svm) در الگوی یادگیری طبقه بندی و رگرسیون را ارائه می کنیم. اولین مساله یادگیری svm تبدیل به فرمول معادل آن، و پس از آن یک لایه شبکه های عصبی بازگشتی برای یادگیری svm پیشنهاد شده است. شبکه عصبی پیشنهادی برای به دست آوردن راه حل بهینه از طبقه بندی بردا...
