Distributed and parallel time series feature extraction for industrial big data applications

25 Oct 2016blue-yonder/tsfresh

The all-relevant problem of feature selection is the identification of all strongly and weakly relevant attributes. This problem is especially hard to solve for time series classification and regression in industrial applications such as predictive maintenance or production line optimization, for which each label or regression target is associated with several time series and meta-information simultaneously.

Time Series Classification from Scratch with Deep Neural Networks: A Strong Baseline

20 Nov 2016cauchyturing/UCR_Time_Series_Classification_Deep_Learning_Baseline

We propose a simple but strong baseline for time series classification from scratch with deep neural networks. Our proposed baseline models are pure end-to-end without any heavy preprocessing on the raw data or feature crafting.

Imaging Time-Series to Improve Classification and Imputation

1 Jun 2015cauchyturing/UCR_Time_Series_Classification_Deep_Learning_Baseline

We used Tiled Convolutional Neural Networks (tiled CNNs) on 20 standard datasets to learn high-level features from the individual and compound GASF-GADF-MTF images. The imputation MSE on test data is reduced by 12.18%-48.02% when compared to using the raw data.

Multivariate LSTM-FCNs for Time Series Classification

14 Jan 2018titu1994/LSTM-FCN

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.

LSTM Fully Convolutional Networks for Time Series Classification

8 Sep 2017titu1994/LSTM-FCN

We propose the augmentation of fully convolutional networks with long short term memory recurrent neural network (LSTM RNN) sub-modules for time series classification. We also explore the usage of attention mechanism to improve time series classification with the Attention Long Short Term Memory Fully Convolutional Network (ALSTM-FCN).

Multivariate Time Series Classification with WEASEL+MUSE

30 Nov 2017patrickzib/SFA

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, an MTS is not only characterized by individual feature values, but also by the interplay of features in different dimensions.

Fast and Accurate Time Series Classification with WEASEL

26 Jan 2017patrickzib/SFA

Time series (TS) occur in many scientific and commercial applications, ranging from earth surveillance to industry automation to the smart grids. On the popular UCR benchmark of 85 TS datasets, WEASEL is more accurate than the best current non-ensemble algorithms at orders-of-magnitude lower classification and training times, and it is almost as accurate as ensemble classifiers, whose computational complexity makes them inapplicable even for mid-size datasets.

Transfer learning for time series classification

5 Nov 2018hfawaz/bigdata18

Transfer learning for deep neural networks is the process of first training a base network on a source dataset, and then transferring the learned features (the network's weights) to a second network to be trained on a target dataset. Therefore, in an effort to predict the best source dataset for a given target dataset, we propose a new method relying on Dynamic Time Warping to measure inter-datasets similarities.

Deep learning for time series classification: a review

12 Sep 2018hfawaz/dl-4-tsc

DNNs have indeed revolutionized the field of computer vision especially with the advent of novel deeper architectures such as Residual and Convolutional Neural Networks. We give an overview of the most successful deep learning applications in various time series domains under a unified taxonomy of DNNs for TSC.

Data augmentation using synthetic data for time series classification with deep residual networks

7 Aug 2018hfawaz/aaltd18

Data augmentation in deep neural networks is the process of generating artificial data in order to reduce the variance of the classifier with the goal to reduce the number of errors. This is surprising as the accuracy of deep learning models for TSC could potentially be improved, especially for small datasets that exhibit overfitting, when a data augmentation method is adopted.
