A Novel Clustering Techniques Evaluation using Monte Carlo Simulation
Abstract: In Machine Learning clustering is one the most significant method. Today, we have data in rich from many sources but in order to get meaningful information from it is very boring task. Machine learning clustering algorithms to create cluster to decode the meaningful information from the data, this analysis approach has gained much popularity in recent years. This paper explores evaluation performance of frequently used existing clustering techniques such as …

Applications of Fuzzy Set in Mathematical Programming
Abstract: The Information in today’s world are uncertain and are under circumstances of increased uncertainty so decisions are difficult to be made. There are different techniques to represent these uncertainties. One of the ways of representing it is with the help of Fuzzy Set Theory & Fuzzy Numbers. One of the very fascinating ideas of using fuzzy set in Mathematical programming and linear programming problems has benefited largely in decision-making, in …

Scaled Box-Cox Quantile Regression Using the Geometric Mean as The Scaling Factor
Abstract: Box-Cox transformation since its proposal has been modified by many authors. It was extended to quantile regression as Box-Cox quantile regression. An option of Box-Cox transformation that doesn’t appear to have been explored much in literature is the scaled Box-Cox transformation. This study extends the Box-Cox quantile regression to accommodate scaling of the response variable using the geometric mean as the scaling factor. A simulation study demonstrates that the scaled …

Tweets Classification using Different Classifiers for Sentiment Analysis
Abstract: Twitter is a famous platform for social networking where people share and engage with "tweets" comments. It is a way of expressing people's opinions or emotions on various topics. Different parties, like producers and consumers, have carried out a sentiment analysis on tweets to gain insights into goods or to analyze the sector. Also, the accuracy of our sentiment analysis forecasts will increase with the recent advances in machine learning …

Indicators of Hospital Service Quality Using Mortality Statistics
Abstract: Death rates have long been used by hospitals as a reliable benchmark for assessing the quality of their medical services. The goal of this study was to determine the gross death rate (GDR) and net death rate (NDR) in King Fahad hospital in Jeddah, Kingdom of Saudi Arabia (KSA), as well as the demographic features of deaths in 2000 according to ICD-10 as indices of hospital treatment quality, from 1994 …
