This is the companion repository for this paper titled "Deep learning for time series classification: a review" published in Data Mining and Knowledge Discovery, also available on ArXiv.
This repository updates the code and documentation for the latest versions of tensorflow, numpy, keras, etc. The original repository is here.
The results in the paper were generated using the Tensorflow 1.14 implementation which can be found here.
The data used in this project comes from two sources:
- The UCR/UEA archive, which contains the 85 univariate time series datasets.
- The MTS archive, which contains the 13 multivariate time series datasets.
The code is divided as follows:
- The main.py python file contains the necessary code to run an experiement.
- The utils folder contains the necessary functions to read the datasets and visualize the plots.
- The classifiers folder contains nine python files one for each deep neural network tested in our paper.
The code has been testing for Tensorflow 2.16.2, numpy 1.26.4 and keras 3.4.1.
Tensorflow requires an NVIDIA GPU to run. You can verify that your pre-requisites are setup correctly by running the hello_tensorflow.py
.
python3 hello_tensorflow.py
If everything is setup correctly, you should see the model training, following by the accuracy and loss.

To install data for testing
cd /dl-4-tsc/archives
wget https://www.cs.ucr.edu/~eamonn/time_series_data_2018/UCRArchive_2018.zip
unzip -P $password UCRArchive_2018.zip
The password can be found here.
Before running, edit main.py
to point to the root of this repository on your local machine. The default
is to use relative paths and run from the top level directory of the respoitory. Otherwise, change the
path on line 83 of main.py
# change this directory for your machine
root_dir = './'
To run a model on one dataset you should issue the following command:
python3 main.py UCRArchive_2018 Coffee fcn _itr_8
which means we are launching the fcn model on the univariate UCR archive for the Coffee dataset (see constants.py for a list of possible options).
I added the results on the 128 datasets from the UCR archive 2018.
Our results in the paper showed that a deep residual network architecture performs best for the time series classification task.
The following table contains the averaged accuracy over 10 runs of each implemented model on the UCR/UEA archive, with the standard deviation between parentheses.
