Multivariate times series classification through an interpretable representation

نویسندگان

چکیده

Multivariate time series classification is a machine learning task with increasing importance due to the proliferation of information sources in different domains (economy, health, energy, crops, etc.). Univariate methods lack ability capture relationships between variables that compose multivariate and therefore cannot be directly extrapolated environments. Despite good performance competitive results proposals published date, they are hard interpret their high complexity. In this paper, we propose method based on an alternative representation series, composed set 41 descriptive features, order improve interpretability obtained. Our proposal uses traditional classifiers over extracted features look for form series. We have selected four state-of-the-art algorithms as base evaluate our method. tested complete University East Anglia repository, obtaining highly interpretable capable explaining achieving statistically indistinguishable from best state-of-the-art.

ShiftTree: An Interpretable Model-Based Approach for Time Series Classification

Efficient algorithms of time series data mining have the common denominator of utilizing the special time structure of the attributes of time series. To accommodate the information of time dimension into the process, we propose a novel instance-level cursor based indexing technique, which is combined with a decision tree algorithm. This is beneficial for several reasons: (a) it is insensitive t...

Extracting Interpretable Features for Early Classification on Time Series

Early classification on time series data has been found highly useful in a few important applications, such as medical and health informatics, industry production management, safety and security management. While some classifiers have been proposed to achieve good earliness in classification, the interpretability of early classification remains largely an open problem. Without interpretable fea...

Multivariate Time Series Prediction via Temporal Classification

One of the important problems in many process industries is how to predict the occurrence of abnormal situations ahead of time in a multivariate time series environment. For example, in an oil refinery, hundreds of sensors (process variables) are installed at different sections of a process unit. These sensors constantly monitor the development of every stage of the process. Typically, each pro...

Multivariate LSTM-FCNs for Time Series Classification

Over the past decade, multivariate time series classification has been receiving a lot of attention. We propose augmenting the existing univariate time series classification models, LSTM-FCN and ALSTM-FCN with a squeeze and excitation block to further improve performance. Our proposed models outperform most of the state of the art models while requiring minimum preprocessing. The proposed model...

Multivariate Time Series Classification with WEASEL+MUSE

Multivariate time series (MTS) arise when multiple interconnected sensors record data over time. Dealing with this high-dimensional data is challenging for every classifier for at least two aspects: First, a MTS is not only characterized by individual feature values, but also by the co-occurrence of features in different dimensions. Second, this typically adds large amounts of irrelevant data a...
