Comparative Study of Fast Stacking Ensembles Families Algorithms

One of the main challenges in Machine Learning and Data Mining fields is the treatment of large Data Streams in the presence of Concept Drifts. This paper presents two families of ensemble algorithms designed to adapt to abrupt and gradual concept drifts. The families Fast Stacking of Ensembles boosting the Old (FASEO) and Fast Stacking of Ensembles boosting the Best (FASEB) are adaptations of the Fast Adaptive Stacking of Ensembles (FASE) algorithm to improve run-time, without presenting a significant decrease in terms of accuracy when compared to the original FASE. In order to achieve a more efficient model, adjustments were made in the update strategy and voting procedure of the ensemble. To evaluate the methods, Naïve Bayes (NB) and Hoeffding Tree (HT) are used, as learners, to compare the performance of the algorithms on artificial and real-world data-sets. An experimental investigation with a total of 32 experiments and the application of Friedman and Bonferroni-Dunn statistical tests showed the families FASEO and FASEB are more efficient than FASE with respect to execution time in many experiments, also some methods achieving better accuracy results.

Evaluating the Effect of Multiple Filters in Automatic Language Identification without Lexical Knowledge

The classical language identification architecture would require a collection of languages independent text and speech information for training by the system before it can identify the languages correctly.This paper also address language identification framework however with data has been downsized considerably from general language identification architecture.The system goal is to identify the type of language being spoken to the system based on a series of trained speech with sound file features and without any language text data or lexical knowledge of the spoken language.The system is also expected to be able to be deployed in mobile platform in future.This paper is specifically about measuring the performance optimisation of audio filters on a CNN model integration for the language identification system.There are several metric to gauge the performance identification system for a classification problem.Precision, recall and F1 Scores is presented for the performance evaluation with different combination of filters together with CNN model as the framework of the language identification system.The goal is not to get the best filter for noise, instead to identify the filter that is a good fit to develop language model with environmental noise for a robust language identification system.Our experiments manage to identify the best combination of filters to increase the accuracy of language identification using short speech.This resulting us to modify our pre-processing phase in the overall language identification system.
2014~2020학년도 대학수학능력시험 문항 내용타당도 분석

was newly selected as a high school advanced elective subject in the 2007 Revised Educational Curriculum. This change, led by the government, was based on the discourse on East Asian History and the efforts from the academia. Scholastic ability tests can be seen as both the end and the start of an educational curriculum, they serve the purpose of measuring how much of the lessons plan have been achieved by the students after teaching and learning.This research analyzes the content validity of 140 questions from the College Scholastic Ability Test’s section from 2014~2020. 2009 and 2011 Revised Curriculum were compared and analyzed, and the components of the exam was examined by question type and year. Questions were divided into subjects of politics, economy, society, and culture based on the goal of , and an additional category was added which combines two or more of the topics in a question. Furthermore, using the division of time periods suggested in the chapters of the curriculum, the proportion of questions on each time era was examined. The result of the analysis showed that the questions were centered on the topic of politics, Chapter V(mid 19th~1945).Achievement standards were used as a reference in order to inspect the questions’ compatibility with the educational curriculum. The questions were first divided by the educational curriculum that was applied and then categorized using the achievement standards. In this step, the compatibility with achievement standards was found, and commonalities among the incompatible questions were also identified.Without active research and search of new materials with the accumulated question bank, it will be difficult to create questions with high discrimination index. Since it is difficult to create questions targeting the same content and achievement standards using the limited amount of resource, it is likely there will be questions outside the content covered in the curriculum. Hence, in order to write questions that test historical knowledge from different angles, we will need experts focusing on different subfields and time eras. In addition, there is a need for further research accomplishments related to in the field of history. This will lead to the development of academic resources for the history instructors and will become the driving force that helps settle into the school environment.

Modeling of Crude Oil Types Classification Using the Naive Bayes Classifier Method

This research is part of previous research regarding the prediction of petroleum's physical properties to help the user get the prediction value of crude oil's physical properties from field test data, which was carried out from Enhanced Oil Recovery Research Laboratory, Petroleum Engineering UPN “Veteran” Yogyakarta. The field data that is measured in the laboratory that has been done is by adding biosurfactants and increasing the temperature. Various steps have been taken to reduce crude oil's viscosity value so that it can be diluted could flow. It is necessary to calculate the viscosity of crude oil in this process to determine the extent of the viscosity level as expected by adding biosurfactants or increasing the temperature that has been carried out in the EOR process. Naive Bayes Classifier is used to classify oil data into three categories: light oil, medium oil, and heavy oil, based on the prediction of the viscosity value. The Naive Bayes Classifier is a robust algorithm for performing machine learning-based predictive modeling that applies the Bayes theorem. This predictive modeling for the physical properties of crude oil was built using the Python programming language and the PyQt5 library to build desktop-based applications. The classification of oil has arrived at labeling the prediction results of crude oil's viscosity into three categories, namely light oil, medium oil, and heavy oil. The test results with testing data produce accurate data; the predicted value is within the specified range.
Problematic Issues of Intellectualizing the Control System of Autonomous Underwater Vehicles

The paper considers ways of intellectualizing the control processes of autonomous underwater vehicles (AUVs) by the example of solving three problems, on which the successful use of AUVs largely depends. The first problem is to create an AUV control system (CS), which ensures the achievement of the mission’s objective in the event of emergencies caused by both external and internal reasons, as well as deliberate and unintentional counteraction. It is shown that for the construction of the AUV’s CS the decentralized multi-agent structure is most suitable, in which each AUV system is an independent intellectual agent with its own control system. The control system must be equipped with a set of adaptive algorithms that ensure: control of AUV in the event of emergency situations, taking into account restrictions on the supply of electric energy, speed, accuracy of autonomous underwater navigation, range of hydro-acoustic communication; rational distribution of energy resources by AUV systems in accordance with the current situation; maintaining the functional stability of the AUV with a partial malfunction of technical means. The second problem is to create an underwater navigation system that ensures the accomplishment of AUV missions at great distances from the base point. Since AUV navigation using only on-board means (inertial navigation system and lag) does not provide the necessary accuracy, a prerequisite for AUV navigation over long distances is to conduct an observation using external sources, the choice of which in the circumstances is a non-trivial task. The third problem is to create a network underwater communication system (NUCS), which provides for the group application of AUVs. The ground analogue of NUCS is network radio communication. But if the latter is fairly well developed, then the former only takes the initial steps. This is due to both the later practical relevance of NUCS, and many fundamental physical factors that impede the development of NUCS, which include: a substantially limited frequency band that can be used in practice for signal transmission; a large propagation time of the hydroacoustic signal compared to the radio signal; the formation of extended shadow zones and fading of the connected signal due to its multipath propagation; significant Doppler distortions, fast variability of the characteristics of the hydroacoustic medium.
An Investigation of Korean Learners’ Acquisition of Chinese Tones

Based on the mid-term examination papers of CSL1 from 2016 to 2018, this paper investigates the tone acquisition of Korean learners. The results are as follows:<BR> First, Korean learners have the best acquisition of the 4th tone. Second, the acquisition of the 2nd tone is the most difficult. The confusion of the 2nd and 3rd tones is obvious. <BR> Based on the analysis of statistical data and the author’s 15 years of teaching experience, this paper puts forward three suggestions for tone teaching.<BR> First, following the principle of ‘easy to difficult’, the teaching order of tones should be changed to the 1st tone→the 4th tone→the 3rd tone→the 2nd tone. Second, we should use the five level tone mark to carry out the tone teaching throughout the course. Thirdly, we should strengthen the contrast training for the tones which are easy to be misidentified.

Application of Online Administration System for Practical Work(PW) in the Petroleum Engineering Department, Universitas Pembangunan Nasional “Veteran” Yogyakarta

Practical Work (PW) is one of the compulsory courses for students in the Petroleum Engineering Department, UPN Veteran Yogyakarta. Previously, the administrative system that was implemented used a manual system. This system has several weaknesses, including the ineffectiveness of drafting course letters, an activity reporting system, and an activity assessment. The ineffectiveness of the Practical Work (PW) administration system can also be seen from the results of the satisfaction survey of the existing administrative system. The survey results stated that 34.6% of 81 respondents stated that the administrative system implemented was less effective. This study creates an online administration system using an online form (google forms) to simplify the system for making course letters, reporting, and assessing Practical Work (PW) activities. The steps were carried out, among others, satisfaction surveys, making online forms, making online SOPs, manuals book, and socializing the application of the online administration system. The application of the online administration system went as expected without any significant obstacles. From this research, it is hoped that the administration system will be more effective and can be paperless. In the future, the system is expected to become a pioneer in the online administration system in the Petroleum Engineering Department.

산업체 규모와 업종에 따른 MSDS 영업비밀 적용 실태조사 연구

Objective: This study analyzed the status of the application of trade secrets in MSDSs according to size and type of industry. The contents of the MSDS non-public approval policy are summarized. We suggest proactive improvement requirements related to the operation of the MSDS non-public approval policy.Methods: To review this subject, we selected 153 manufacturers and six importers in such fields as organic chemical production. The trade secrets application status and ratio (%) of MSDSs by industry size and industry classification were investigated. Improvements toward a proactive system related to the operation of the MSDS non-public approval policy under the Occupational Safety and Health Act(OSHA) were summarized.Results and Conclusions: According to the results, the trade secret ratio in MSDSs by industry size was 33% in workplaces with less than 50 employees, 23.1% in workplaces with more than 50 but less than 100 workers, 73% in workplaces with more than 100 workers, and 83.4% in workplaces with 300 or more workers. For the trade secret writing rate for MSDSs by industry, the highest was MOCCP (Manufacture of ink, paint, coating and similar products) at 80.9%. MOC (Manufacture of other chemicals) was the lowest at 16.2%. We propose four proactive efforts to minimize the administrative burden of implementation of the MSDS non-public approval policy. The results of this study can be used as basic data for policy improvements to make more effective use of MSDS.
Creative Industries Development Strategy Based on Craftsmen Vacuum Forming In Makassar

One of the obstacles in developing a sustainable industry is related to limitations in terms of skills and knowledge.This is related to simple technologies that allow them to be used in the industry.This limitation results in their ability to be less aware of opportunities to participate in economic development.One of the plastic molding technologies that can produce plastic-based products that are easy to do with simple tools is the vacuum forming method.Dissemination of technical knowledge of production must be introduced to craftsmen so that they can contribute to the producing process to supply the household, especially in the automotive industry.This can be done through education and training programs as well as counseling and guidance in the field of industrial development.Therefore, it is needed to initiate the growth of this vacuum forming industry sooner.It is expected from this coaching model to have a positive impact on growing new industries in Makassar City.
