InceptionTime: Finding AlexNet for Time Series Classification

This is the companion repository for our paper titled InceptionTime: Finding AlexNet for Time Series Classification published in Data Mining and Knowledge Discovery and also available on ArXiv.

Inception module

inception module


The data used in this project comes from the UCR/UEA archive. We used the 85 datasets listed here.


You will need to install the following packages present in the requirements.txt file.


The code is divided as follows:

  • The 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 two python files: (1) contains the inception network; (2) contains the code that ensembles a set of Inception networks.

Adapt the code for your PC

You should first consider changing the following line. This is the root file of everything (data and results) let's call it root_dir.

After that you should create a folder called archives inside your root_dir, which should contain the folder UCR_TS_Archive_2015. The latter will contain a folder for each dataset called dataset_name, which can be downloaded from this website.

The names of the datasets are present here. You can comment this line to run the experiments on all datasets.

Once you have done all that, you can proceed to run on a single archive.

Run InceptionTime on a single Archive

You should issue the following command python3 InceptionTime.

Run the hyperparameter search for InceptionTime on a single Archive

You should issue the following command python3 InceptionTime_xp.

Run the length experiment on the InlineSkate dataset

You should first issue the following command python3 run_length_xps to generate the resamples. Then you should issue the following command python3 InceptionTime but make sure that the InlineSkateXPs is chosen here.

Receptive field

To run the experiments on the synthetic dataset, you should issue the following command python3


The result (i.e. accuracy) for each dataset will be present in root_dir/results/nne/incepton-0-1-2-4-/UCR_TS_Archive_2015/dataset_name/df_metrics.csv.

The raw results can be found here and generated using the following command python3 generate_results_csv.

We added the full results for the 128 datasets from the UCR archive, they can be found here.

The results-inception-128.csv file contains five individual runs of the Inception model over the 128 datasets from the UCR 2018 archive.

Critical difference diagrams

If you would like to generate such a diagram, take a look at this code!

Training time plots

These plots were generated using the matplotlib library.

Accuracy vs train size Accuracy vs series length

Receptive field

This plot was generated by issuing this command python3 plot_results.
