Segmented shape-symbolic time series representation

This paper introduces a symbolic time series representation using monotonic sub-sequences and bottom up segmentation. The representation minimizes the square error between the segments and their monotonic approximations. The representation can robustly classify the direction of a segment and is scale invariant with respect to the time and value dimensions. This paper describes two experiments. ...

Clustering Symbolic Time-Series using L-tuples

Among the many dimensionality reduction methods for timeseries data, Symbolic Aggregate approXimation (SAX) is perhaps the most popular due to its simplicity and uniqueness. With SAX, time-series data can be represented as string sequences which enables the utilization of methods found in text mining and bioinformatics to enhance data mining tasks. We propose an application of L-tuples to impro...

1d-SAX: A Novel Symbolic Representation for Time Series

SAX (Symbolic Aggregate approXimation) is one of the main symbolization technique for time series. A well-known limitation of SAX is that trends are not taken into account in the symbolization. This paper proposes 1d-SAX a method to represent a time series as a sequence of symbols that contain each an information about the average and the trend of the series on a segment. We compare the efficie...

Deep Symbolic Representation Learning for Heterogeneous Time-series Classification

In this paper, we consider the problem of event classification with multi-variate time series data consisting of heterogeneous (continuous and categorical) variables. The complex temporal dependencies between the variables combined with sparsity of the data makes the event classification problem particularly challenging. Most state-of-art approaches address this either by designing hand-enginee...
