Can we Take Advantage of Time-Interval Pattern Mining to Model Students Activity?

Oriane Dermy, Armelle Brun
2020 Educational Data Mining  
Finally, we show that time-interval pattern mining brings additional information compared to sequential pattern mining.  ...  Experiments reveal that frequent time-interval patterns are actually identified, which means that some students' activities are regulated not only by the order of learning resources but also by time.  ...  For each of them, the number of intervals, the maximal horizon, the fitting of the set, the frequency of each frequent interval, as well as the number of frequent patterns, are displayed.  ...

Procedural Steps for Knowledge Mining in Time Series

Kaustuva ChandraDev, Sibananda Behera
2013 International Journal of Computer Applications  
Symbolic intervals which form temporal patterns are usually formulated through Allen's interval relations that originate in temporal reasoning.  ...  We present mining procedural steps which are more efficient, effective and based on item set techniques.  ...  Since it is similar to the mining of closed frequent item sets, we therefore follow the CHARM [12] algorithm.  ...

Discovery of temporal association rules with hierarchical granular framework

Tzung-Pei Hong, Guo-Cheng Lan, Ja-Hwung Su, Pei-Shan Wu, Shyue-Liang Wang
2016 Applied Computing and Informatics  
However, an infrequent item for the entire time may be frequent within part of the time. We thus organize time into granules and consider temporal data mining for different levels of granules.  ...  Most of the existing studies in temporal data mining consider only lifespan of items to find general temporal association rules.  ...  In this paper, we consider the phenomenon that an itemset may not be frequent in the entire time interval, but may be frequent in a partial time interval.  ...
