An Experimental Study on Hypothyroid Using Rotation Forest
نویسندگان
چکیده
This paper majorly focuses on hypothyroid medical diseases caused by underactive thyroid glands. The dataset used for the study on hypothyroid is taken from UCI repository. Classification of this thyroid disease is a considerable task. An experimental study is carried out using rotation forest using features selection methods to achieve better accuracy. An important step to gain good accuracy is a preprocessing step, thus here two feature selection techniques are used. A filter method, Correlation features subset selection and wrappers method has helped in removing irrelevant as well as useless features from the data set. Fourteen different machine learning algorithms were tested on hypothyroid data set using rotation forest which successfully turned out giving positively improved results.

An Experimental Study on Rotation Forest Ensembles
Rotation Forest is a recently proposed method for building classifier ensembles using independently trained decision trees. It was found to be more accurate than bagging, AdaBoost and Random Forest ensembles across a collection of benchmark data sets. This paper carries out a lesion study on Rotation Forest in order to find out which of the parameters and the randomization heuristics are respon...
متن کاملA cost-sensitive rotation forest algorithm for gene expression data classification
Existing works show that the rotation forest algorithm has competitive performance in terms of classification accuracy for gene expression data. However, most existing works only focus on the classification accuracy and neglect the classification costs. In this study, we propose a cost-sensitive rotation forest algorithm for gene expression data classification. Three classification costs, namel...
متن کاملThe effect of 8-week online scapular-focused training on scapular kinematics, proprioception, and selected muscles strength in female volleyball players with Glenohumeral Internal Rotation Deficit
Introduction and aim: One of the most significant risk factors for throwing athletes is an internal rotation deficit of the shoulder joint. This study investigated 8-week online scapular-focused training on the scapular kinematics, proprioception, and strength of particular shoulder muscles in female volleyball players with Glenohumeral Internal Rotation Deficit. Methodology: The present study...
متن کاملOn the Use of Default Parameter Settings in the Empirical Evaluation of Classification Algorithms
We demonstrate that, for a range of state-of-the-art machine learning algorithms, the differences in generalisation performance obtained using default parameter settings and using parameters tuned via cross-validation can be similar in magnitude to the differences in performance observed between state-of-the-art and uncompetitive learning systems. This means that fair and rigorous evaluation of...
متن کاملStudy on Slash Pine (Pinus elliottii) as a Short Rotation Forestry in the North of Iran
Forests of Iran located on the Southern border of the Caspian Sea cover 1.9 million hectares. The Caspian forests are divided into four separate forestry areas. One of these being Guilan influx area with total area of 565000 hectares. About 30 to 40 percent of Guilan province forests are suitable to short rotation forestry for afforestation. Slash pine (Pinus elliottii) is one of the main exo...
