This paper focuses on forecasting the medium term (1-month ahead and 1-year ahead) of electricity peak demand in Thailand by using three machine learnings and ensemble method. The machine learnings include artificial neural network (ANN), support vector machine (SVM), and deep belief network (DBN). For the comparative performance between each model, mean absolute percentage error (MAPE) is used as the measurement. The result implies that the ensemble model of ANN and DBN is the best method for 1-month ahead with MAPE 1.44%, and ANN is the best method for 1-year ahead forecasting with MAPE 1.47%.","PeriodicalId":442255,"journal":{"name":"2019 17th International Conference on ICT and Knowledge Engineering (ICT&KE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131031848","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}

The front-end department, which is the medical record department, is the first place to contact patients. It provides service for all type of out-patients, so out-patients have to wait for a long time. This results in low satisfaction of the patients. However, this department is working 24 hours, thus, it isdifficult to improve the queue system in a real environment. The simulation is an effective tool to solve the problem. Based on the data collection from Thammasat University hospital, the discrete event simulation model of this department is developed. Model verification and validation are conducted and the resultconfirms that the model is worked as calculated and generates the same result as in the real system. The aim of this paper is to develop the simulation model that provides an accurate analysis to help support a decision making of the hospital in the medical record department.","PeriodicalId":442255,"journal":{"name":"2019 17th International Conference on ICT and Knowledge Engineering (ICT&KE)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132784134","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}

In the first IoT-related part of the paper, a Wi-Fi P2P system (Peer to Peer) including a set of Smart Sofas, which were easily connected with a Xbox Kinect Camera without requiring a wireless access, was initially designed and developed. The Smart Sofas contained Weight Pressure Sensors, whereas, the Smart Cameras worked based on a Facial Recognition algorithm. The system was capable of identifying, recording and storing the exact location of a couple (i.e., two individuals) sitting on them in addition to their body language/gesture. Subsequently, 74 couples (or 148 persons) were voluntarily invited to join an experiment with the purpose of studying their behavior —within the duration of time they were used to getting back home from work— when sitting (or lying down) on a pair of smart sofas that was deliberately inserted in the living room of their home. The experiment lasted for one month and excluded the weekends so as to give the couples enough privacy they needed to carry on their normal life without any annoyance or disturbance. In the second part of the study, the Fuzzy Miner algorithm, which is a process discovery technique, was applied on the collected/synchronized (sofa and camera) data. To do this, the Disco Fluxicon, which is a Process Mining platform/tool, was used. The couples' data (i.e., the Sofa and Camera data) included 888 Events with a Mean Case Duration of 3.1 minutes. In the third part of the study, the data was divided into two separate event logs as the following: (1) The event log of the couples who showed/reported “Having Problems” in their relationship while taking part in the experiment, versus, (2) The event log of the couples who showed/reported “Not Having Any Problems”. Furthermore, the “Not Having Any Problems” data also was divided into another two sub-sets as follows: (i) Those who felt “Extremely Happy and Satisfied” versus (ii) Those who felt happy but in a very “Normal and Ordinary (Neutral)” way in their relationship. Subsequently, a statistical analysis of binary classification in terms of a Confusion Matrix and based on the F1-Score coefficient (or F-measure) was conducted so as to consider both the Precision and the Recall coefficients of the results. According to the findings of the study, with rather a high degree of accuracy (i.e., F-Score = 0.7563), it was realized that the couples who were “Not Having Any Problems” in their relationship showed tendency to represent/manifest one (or a mixture) of the following sitting positions while sitting on a sofa, respectively: “Legs on Lap”, “Cuddling in the Corner”, “Corner Cuddle with Tucked Legs”, “Side-by-Side (Touching but Not Cuddling)” and “Cuddling in the Middle”. And finally, the current work provides groundwork for further research and studies. In the future, more couples in a longer period of time (including the weekends) also will ","PeriodicalId":442255,"journal":{"name":"2019 17th International Conference on ICT and Knowledge Engineering (ICT&KE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130124616","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}

As palm oil market in Myanmar represents the back bone of Myanmar Edible Oil Dealers Association (MEODA), we propose the predictive model to aid in decision making process of palm oil importers whether they should conduct import transaction today or not in this paper. This prediction of palm oil price condition in Myanmar has been taken on the previous dataset supported by MEODA to eliminate ever-increasing risks and uncertainties in the future. This model will forecast whether the price of palm oil in Myanmar will rise or not in 14 days from today, the length of period is necessary to be ready to trade imported palm oil in local market for Myanmar importers. Our model is trained using C4.5 Random Forest Classification Algorithm on the palm oil market dataset from MOEDA. Hyperparameter tuning techniques are conducted to analyze whether the predictive performance can be enhanced. From the obtainable dataset in Myanmar palm oil market, the predictive model with chosen hyperparameters set achieves the prediction accuracy of 91.11% on the test dataset.","PeriodicalId":442255,"journal":{"name":"2019 17th International Conference on ICT and Knowledge Engineering (ICT&KE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124542085","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}
