Abstract

In the last decade we have seen a huge increase of interest for time series methods in Data Mining and Knowledge Discovery. Such interest has culminated in the proposal of literally hundreds of methods for tasks such as classification, cluste- ring, anomaly detection, motif detection, among others. Empirical research has demonstrated that time series similarity-based methods provide very competitive results, frequently outperforming more complex methods for tasks such as clas- sification, clustering and anomaly detection. We believe that the superiority of similarity-based methods is largely due to the community incessant work on dis- tance invariances such as warping, baseline, occlusion, rotation, etc. In contrast, statistical methods based on autoregression and moving averages are considered the state-of-the-art for time series modeling and prediction for over half-century now. In this research proposal, we ask if it really is the case, or if the Data Mining community has more to offer. In particular, we raise the hypothesis that similarity- based methods are simple, effective and parameter-light approaches for time series prediction. Although, similarity-based time series prediction methods have been re- searched in the recent past, we believe that previous research has failed to identify the correct invariances required for this task. The central hypothesis of this work is that only the right combination of offset, amplitude and recently-proposed com- plexity invariance, combined with a policy to avoid trivial matches leads to precise and meaningful predictions.
