Abstract: in this paper, we proposed an exact method to discover all order-preserving submatrices (opsms) based on frequent sequential pattern mining. Firstly, an existing algorithm calacs is adjusted to disclose all common subsequences between every two row sequences, therefore all the deep opsms corresponding to long patterns with few supporting sequences will not be missed.

The order-preserving submatrices (opsms) are employed to discover significant biological associations between genes and experiment conditions. Herein, we propose a new relaxed opsm model by considering the linearity relaxation, which is called the bucket opsm (bopsm) model. An efficient method called apribopsm is developed to exhaustively mine such bopsm patterns.

Opsm is a deterministic greedy algorithm dedicated to find large order-preserving submatrices.
