Analysis of Active Learning for Social Media to Support Crisis Management

Mayuri S. Waghmare, Tarun Yengantiwar
2020 International Journal of Scientific Research in Science Engineering and Technology  
AOMPC is an online learning algorithm that runs on data streams and contains active learning algorithms for actively querying the label of obscure unnamed data.  ...  Therefore, we propose a new active online multi-prototype classifier called AOMPC. It identifies relevant data related to a crisis.  ...  CONCLUSION This paper presents a streaming analysis framework for distinguishing between relevant and irrelevant data items.  ...

Abstracting Low-level Event Data for Meaningful Process Analysis

Adrian Rebmann
2021 International Conference on Business Process Management  
Most process mining techniques assume the event data to be on the right level of detail for analysis, i.e. the level of activities.  ...  Specifically, we will focus on three research streams, developing solutions that consider the meaning of events, take the purpose of analyses into account, and address online settings.  ...  The majority of the available process mining techniques still makes the assumption that event data are captured on the level of activities relevant for analysis.  ...

Online temporal-spatial analysis for detection of critical events in Cyber-Physical Systems

Zhang Fu, Magnus Almgren, Olaf Landsiedel, Marina Papatriantafilou
2014 2014 IEEE International Conference on Big Data (Big Data)  
Motivated by the fact that critical events of CPSs often have temporal-spatial properties, we focus on identifying critical events by an online temporal-spatial analysis on the data stream of messages.  ...  We explicitly model the online detection problem as a single-linkage clustering on a data stream over a sliding-window, where the inherent computational complexity of the detection problem is derived.  ...  We model the temporalspatial analysis for detecting critical events through the problem of single-linkage clustering of a data stream over a sliding-window. 2) We provide G-SLC, a grid-based single linkage  ...

Recent trends in streaming data analysis, concept drift and analysis of dynamic data sets

Albert Bifet, Barbara Hammer, Frank-Michael Schleif
2019 The European Symposium on Artificial Neural Networks  
In this tutorial we provide an introduction into the field of streaming data analysis summarizing its major characteristics and highlighting important research directions in the analysis of dynamic data  ...  Today, many data are not any longer static but occur as dynamic data streams with high velocity, variability and volume. This leads to new challenges to be addressed by novel or adapted algorithms.  ...  Acknowledgment BH gratefully acknowledges funding in the frame of the CITEC centre of excellence and the BMBF project ITS ML, grant number 01IS18041A.  ...

Formative Assessment as an Online Instruction Intervention

Zexuan Chen, Jianli Jiao, Kexin Hu
2021 International Journal of Distance Education Technologies  
Analysis of students' learning records and scores indicated that students engaged themselves actively in all of the online learning activities and had gained high scores in all tasks, quizzes, and tests  ...  Data were collected from the first five weeks of a course that was temporarily converted from blended learning to be fully online in time of school closure.  ...  Data Collection and Analysis Data for the present study came from two sources: students' learning records and questionnaire responses.  ...

Can You Tell If they're Learning? Using a Pedagogical Framework to Measure Pedagogical Activity

Tim ORiordan, David E. Millard, John Schulz
2015 2015 IEEE 15th International Conference on Advanced Learning Technologies  
The proliferation of Web-based learning objects makes finding and evaluating online resources problematic.  ...  This has value as it categorises discussion in terms of pedagogical activity rather than Web interaction.  ...  We believe Dial-e has importance for the analysis of online discussion in terms of actual focus on learning activity rather than Web-based interaction.  ...
