Data Analytic Approaches for Mining Process Improvement—Machinery Utilization Use Case
resources Article Data Analytic Approaches for Mining Process Improvement—Machinery Utilization Use Case Edyta Brzychczy 1,* , Paulina Gackowiec 1 and Mirko Liebetrau 2 1 Faculty of Mining and Geoengineering, AGH University of Science and Technology, 30-059 Cracow, Poland; [email protected] 2 Talpasolutions GmbH, 45327 Essen, Germany; [email protected] * Correspondence: [email protected] Received: 5 December 2019; Accepted: 31 January 2020; Published: 7 February 2020 Abstract: This paper investigates the application of process mining methodology on the processes of a mobile asset in mining operations as a means of identifying opportunities to improve the operational efficiency of such. Industry 4.0 concepts with related extensive digitalization of industrial processes enable the acquisition of a huge amount of data that can and should be used for improving processes and decision-making. Utilizing this data requires appropriate data processing and data analysis schemes. In the processing and analysis stage, most often, a broad spectrum of data mining algorithms is applied. These are data-oriented methods and they are incapable of mapping the cause-effect relationships between process activities. However, in this scope, the importance of process-oriented analytical methods is increasingly emphasized, namely process mining (PM). PM techniques are a relatively new approach, which enable the construction of process models and their analytics based on data from enterprise IT systems (data are provided in the form of so-called event logs). The specific working environment and a multitude of sensors relevant for the working process causes the complexity of mining processes, especially in underground operations. Hence, an individual approach for event log preparation and gathering contextual information to be utilized in process analysis and improvement is mandatory. -

Process Mining Online Assessment Data
Educational Data Mining 2009 Process Mining Online Assessment Data Mykola Pechenizkiy, Nikola Trčka, Ekaterina Vasilyeva, Wil van der Aalst, Paul De Bra {m.pechenizkiy, e.vasilyeva, n.trcka, w.m.p.v.d.aalst}@tue.nl, [email protected] Department of Computer Science, Eindhoven University of Technology, the Netherlands Abstract. Traditional data mining techniques have been extensively applied to find interesting patterns, build descriptive and predictive models from large volumes of data accumulated through the use of different information systems. The results of data mining can be used for getting a better understanding of the underlying educational processes, for generating recommendations and advice to students, for improving management of learning objects, etc. However, most of the traditional data mining techniques focus on data dependencies or simple patterns and do not provide a visual representation of the complete educational (assessment) process ready to be analyzed. To allow for these types of analysis (in which the process plays the central role), a new line of data-mining research, called process mining, has been initiated. Process mining focuses on the development of a set of intelligent tools and techniques aimed at extracting process-related knowledge from event logs recorded by an information system. In this paper we demonstrate the applicability of process mining, and the ProM framework in particular, to educational data mining context. We analyze assessment data from recently organized online multiple choice tests and demonstrate the use of process discovery, conformance checking and performance analysis techniques. 1 Introduction Online assessment becomes an important component of modern education. It is used not only in e-learning, but also within blended learning, as part of the learning process. -

Patil CoE, Pimpri, SPPU, Pune 411 007 India; [email protected] * Correspondence: [email protected]; Tel.: +91-989-023-9995 Received: 16 July 2018; Accepted: 10 October 2018; Published: 17 October 2018 Abstract: Data growth in today’s world is exponential, many applications generate huge amount of data streams at very high speed such as smart grids, sensor networks, video surveillance, financial systems, medical science data, web click streams, network data, etc. In the case of traditional data mining, the data set is generally static in nature and available many times for processing and analysis. However, data stream mining has to satisfy constraints related to real-time response, bounded and limited memory, single-pass, and concept-drift detection. The main problem is identifying the hidden pattern and knowledge for understanding the context for identifying trends from continuous data streams. In this paper, various data stream methods and algorithms are reviewed and evaluated on standard synthetic data streams and real-life data streams. Density-micro clustering and density-grid-based clustering algorithms are discussed and comparative analysis in terms of various internal and external clustering evaluation methods is performed. It was observed that a single algorithm cannot satisfy all the performance measures. -

Massive Online Analysis, a Framework for Stream Classification and Clustering
MOA: Massive Online Analysis, a Framework for Stream Classification and Clustering. Albert Bifet1, Geoff Holmes1, Bernhard Pfahringer1, Philipp Kranen2, Hardy Kremer2, Timm Jansen2, and Thomas Seidl2 1 Department of Computer Science, University of Waikato, Hamilton, New Zealand fabifet, geoff, [email protected] 2 Data Management and Exploration Group, RWTH Aachen University, Germany fkranen, kremer, jansen, [email protected] Abstract. In today's applications, massive, evolving data streams are ubiquitous. Massive Online Analysis (MOA) is a software environment for implementing algorithms and running experiments for online learn- ing from evolving data streams. MOA is designed to deal with the chal- lenging problems of scaling up the implementation of state of the art algorithms to real world dataset sizes and of making algorithms compa- rable in benchmark streaming settings. It contains a collection of offline and online algorithms for both classification and clustering as well as tools for evaluation. Researchers benefit from MOA by getting insights into workings and problems of different approaches, practitioners can easily compare several algorithms and apply them to real world data sets and settings. MOA supports bi-directional interaction with WEKA, the Waikato Environment for Knowledge Analysis, and is released under the GNU GPL license. Besides providing algorithms and measures for evaluation and comparison, MOA is easily extensible with new contri- butions and allows the creation of benchmark scenarios through storing and sharing setting files. 1 Introduction Nowadays data is generated at an increasing rate from sensor applications, mea- surements in network monitoring and traffic management, log records or click- streams in web exploring, manufacturing processes, call detail records, email, blogging, twitter posts and others. -

An Extensible Framework for Data Stream Clustering Research with R
JSS Journal of Statistical Software February 2017, Volume 76, Issue 14. doi: 10.18637/jss.v076.i14 Introduction to stream: An Extensible Framework for Data Stream Clustering Research with R Michael Hahsler Matthew Bolaños John Forrest Southern Methodist University Microsoft Corporation Microsoft Corporation Abstract In recent years, data streams have become an increasingly important area of research for the computer science, database and statistics communities. Data streams are ordered and potentially unbounded sequences of data points created by a typically non-stationary data generating process. Common data mining tasks associated with data streams include clustering, classification and frequent pattern mining. New algorithms for these types of data are proposed regularly and it is important to evaluate them thoroughly under standardized conditions. In this paper we introduce stream, a research tool that includes modeling and simu- lating data streams as well as an extensible framework for implementing, interfacing and experimenting with algorithms for various data stream mining tasks. The main advantage of stream is that it seamlessly integrates with the large existing infrastructure provided by R. In addition to data handling, plotting and easy scripting capabilities, R also provides many existing algorithms and enables users to interface code written in many program- ming languages popular among data mining researchers (e.g., C/C++, Java and Python). In this paper we describe the architecture of stream and focus on its use for data stream clustering research. stream was implemented with extensibility in mind and will be ex- tended in the future to cover additional data stream mining tasks like classification and frequent pattern mining.
