Therefore, this paper aims to analyze profiles of tourists using data mining decision tree techniques where several combinations of the number of branches (2 and 3 branches) and different target splitting rules (Entropy, Gini, and Probability Chi-square) have been applied on comprehensive survey data and to find out the best performing algorithm among the six models for tourism knowledge discovery. Results show that there are a various type of tourists with each group having different patterns or rules. This research study can be very helpful for tourist association, hospitality and hotel managers.Tourism industry in Malaysia has been customarily thought and advanced towards universal markets since its early stages arrange in 1960s.

While strong muscular strength and proper riding posture are important to minimize strain, the significances of these attributes on cycling fatigue were unclear. An attempt was made to identify significant attributing features for indoor cycling fatigue classification based on an experimental study involving twenty healthy postgraduates. The participants were tasked to perform an indoor cycling fatigue experiment at 6km/h with gradual speed increment till fatigue level achieved. The accelerometry, sacral trajectory and the lower limb kinematic changes were measured. Significant feature subset selection was determined using the wrapper approach with IBk algorithm. The featured data were later classified on IBk, SMO, ZeroR, J48 and Vote followed by subsequent discriminant analysis. The results demonstrated that the significant attributes yielded 95.0% and 75% ...","PeriodicalId":325925,"journal":{"name":"THE 4TH INNOVATION AND ANALYTICS CONFERENCE & EXHIBITION (IACE 2019)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116502919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach does not require the proportional hazard assumption and the distribution of survival time can be unknown. Some papers apply SURLS-SVM on both simulation study and real data without considering feature selection. The performance of statistical methods can be determined by choosing relevant features selected as input. Therefore, the feature selection method is necessary to be applied in SURLS-SVM. In this paper, the Cox PHM and the SURLS-SVM with feature selection are applied on simulated data and clinical data, i.e. survival of cervical cancer patients. These two approaches are compared using prognostic index so-called concordance index (c-index). For both data sets, the c-index obtained from SURLS-SVM, with or without feature selection, is much higher than the one obtained from Cox PHM. On the cervical cancer data, SURLS-SVM with feature selection selects 10 relevant features out of 12 features.

The project management criteria are playing a vital role for completion of any project. The aim of this paper is to evaluate five main project criteria (time, cost, quality, risk, and safety) mathematically by using a multi-criteria method in order to assist stakeholders or project managers in decision-making. The fuzzy Analytic Hierarchy Process (AHP) is selected with the use of triangular fuzzy numbers for pairwise comparison scales in prioritizing the criteria in managing projects. Utilizing the fuzzy AHP technique can facilitate uncertainty in doing evaluation. In this study, one expert who is a project manager with many years of experience was asked to carry out the evaluation. The results show that the expert’s main concern in managing project is time, and cost is the second important. The study demonstrates how uncertainty in making evaluation of multiple criteria can be solved by using fuzzy method such as fuzzy AHP, in contrary to the crisp or the traditional AHP which is based on specific values, the evaluator(s) are always ambiguous and vague to give exact judgment. Hence, the application of this fuzzy method can make the assessment outcomes more accurate, scientific, and objective. It is anticipated that this work may serve as a support tool for stakeholders in improving the project management quality level.Project management is one of the most important issues to fulfil organizational objectives.

We develop a permutation testing to investigate whether episodes’ intensity exhibits change that goes beyond random variation when episodes are in temporal proximity. Further analysis consists of comparison between the two cases i.e. excluding episodes within 24 hours and including those episodes with regards to their correlations between the intensity of the episodes.
