Subgraph Mining
The amount of available data is increasing very fast. With this data, the desire for data mining is also growing. More and larger databases have to be searched to find interesting (and frequent) elements and connections between them. Most often the data of interest is very complex. It is common to model complex data with the help of graphs consisting of nodes and edges that are often labeled to...
متن کاملSubgraph Mining for Anomalous Pattern Discovery in Event Logs
Pattern discovery has been the center of attention of data mining research for a long time, with patterns languages varying from simple to complex, according to the needs of the applications and the format of data. In this talk, I will take a view on pattern mining that combines elements from neighboring areas. More specifically, I will describe our previous research work in the intersection of...
متن کاملAn Efficiently Computable Support Measure for Frequent Subgraph Pattern Mining
Frequent subgraph pattern mining is an important graph mining task. While the majority of existing systems focus on the transactional setting, where every transaction is a separate, independent graph, in recent years there has been an increasing interest in mining large networks. In particular, given a network (also called database graph) D, a pattern language L, a frequency measure freq and a ...
متن کاملVertex unique labelled subgraph mining
With the successful development of efficient algorithms for Frequent Subgraph Mining (FSM), this paper extends the scope of subgraph mining by proposing Vertex Unique labelled Subgraph Mining (VULSM). VULSM has a focus on the local properties of a graph and does not require external parameters such as the support threshold used in frequent pattern mining. There are many applications where the m...
متن کاملMining Minimal Contrast Subgraph Patterns
In this paper, we introduce a new type of contrast pattern, the minimal contrast subgraph. It is able to capture structural differences between any two collections of graphs and can be useful in chemical compound comparison and building graph classification models. However, mining minimal contrast subgraphs is a challenging task, due to the exponentially large search space and graph (sub)isomor...
