• Paper: Mourad Khayati, Ines Arous, Zakhar Tymchenko and Philippe Cudré-Mauroux: ORBITS: Online Recovery of Missing Values in Multiple Time Series Streams. PVLDB 2021.
• Algorithms: The benchmark evaluates all the algorithms mentioned in the paper: ORBITS, SPIRIT, SAGE, OGDImpute, pcaMME, TKCM and M-RNN.
• Datasets: The benchmark evaluates all the datasets used in the paper: gas (drfit10), motion, bafu, and soccer.
• Scenarios: The benchmark will execute the full set of 11 recovery scenarios and report the recovery error (RMSE, MSE and MAE) and correlation (Pearson and Spearman). A detailed description of the recovery scenarios can be found here.
• News: This code is mentioned in the VLDB reproducibility highlights.

Prerequisites | Build | Execution | Citation

• Ubuntu 18 or 20 (including Ubuntu derivatives, e.g., Xubuntu).
• Clone this repository: https://github.com/eXascaleInfolab/orbits_repro .
• Mono: Install mono from https://www.mono-project.com/download/stable/ (takes a few minutes).

• Build the Testing Framework using the installation script located in the root folder (takes a few minutes):

    $ sh install_linux.sh

• We provide three different scripts to reproduce the experiments. In case you are using the same machine to reproduce the results, the three scripts should be executed sequentially.

1. The results and plots of all techniques, except MRNN, can be obtained by running the following script (takes ~3 days):

    $ cd TestingFramework/bin/Debug/
    $ sh repro.sh

2. The results of MRNN can be obtained by running the following script (takes 2-7 days, depending on the machine):

     $ cd TestingFramework/bin/Debug/
     $ sh repro_extra_mrnn.sh

3. The runtime results of ssv (Fig 13a and 13b: Soccer dataset) take a considerable amount of time and are, thus, not reported. These results can be obtained by running the following script (takes ~3 days):

     $ cd TestingFramework/bin/Debug/
     $ sh repro_extra_ssv.sh

Manual aggregation over mutiple results. The reproducibility of this figure is very hard to automate.

We compute the AVG for each technique over three runs. The absolute correlation values might be slightly different as, in each run, we randomly pick a different time series to recover.
