Main research

Discovering spatial high utility itemsets in spatiotemporal databases

High Utility Itemset Mining (HUIM) is an important knowledge discovery technique in data mining. It aims to discover all itemsets that have high value in the data. Most previous works focussed on finding these itemsets in transactional databases, and did not take into account the spatiotemporal characteritics of an item in the data. Consequently, HUIM fails to discover useful information hidden in very large spatiotemporal data.

We propose a generic model of Spatial High Utility Itemset (SHUI) that may exist in a spatiotemporal database. The significance of the proposed itemsets has been demonstrated with a case study on traffic congestion data.

(Collaboration with NICT, Japan. NICT has provided the traffic congestion and rainfall data.)

Discovering Periodic Patterns in Temporal Databases

Periodic Patterns are an important class of regularities that exist in a temporal databases. In this study, we have investigated novel models and fast algorithms to find interesting periodic patterns in very large databases.


We have published papers in top-tier conferences, such as EDBT (CORE rank A), SSDBM (CORE rank A), PAKDD (CORE RANK A) and IEEE BIG DATA (CORE rank not yet available).
