spartan2 is a collection of data mining algorithms on big graphs and time series, providing three basic tasks: anomaly detection, forecast, and summarization. (see readthedocs, and tutorials )
Graphs and time series are fundamental representations of many key applications in a wide range of
- online user behaviors, e.g. following in social media, shopping, and downloading Apps,
- finance, e.g. stock tradings, and bank transfers,
- sensor networks, e.g. sensor readings, and smart power grid, and
- health, e.g. electrocardiogram, photoplethysmogram, and respiratory inductance plethysmography.
In practice, we find that thinking graphs and time series as matrices or tensors can enable us to find efficient (near linear), interpretable, yet accurate solutions in many applications. Therefore, our goal is developping a collectioin of algorithms on graphs and time series based on tensors (matrix is a 2-mode tensor).
In real world, those tensors are sparse, and we are required to make use of the sparsity to develop efficient algorithms. That is why we name the package as spartan: sparse tensor analytics.
The package named spartan can be imported and run independently as a usual python package. Everything in package spartan is viewed as a tensor (sparse).
This project requires Python 3.7 and upper. We suggest recreating the experimental environment using Anaconda through the following steps.
-
Install the appropriate version for Anaconda from here - https://www.anaconda.com/distribution/
-
Create a new conda environment named "spartan"
conda create -n spartan python=3.7 conda activate spartan -
If you are a normal USER,
# install spartan using pip pip install spartan2 -
If you want to contribute, or prefer to run directly on the code,
Please do the following setup
-
4.1 Clone the project from github
git clone git@github.com:BGT-M/spartan2.git
-
4.2 Install requirements.
# [not recommended]# pip install --user --requirement requirements # using conda tool conda install --force-reinstall -y --name spartan -c conda-forge --file requirements
or use the following way
# this may not work in ubuntu 18.04 python setup.py install -
4.3 Install code in development mode
# in parent directory of spartan2 pip install -e spartan2 -
4.4 Since you install your package to a location other than the user site-packages directory, you will need to add environment variable PYTHONPATH in ~/.bashrc
export PYTHONPATH=/<dir to spartan2>/spartan2:$PYTHONPATH
or prepend the path to that directory to your PYTHONPATH environment variable.
import sys sys.path.append("/<dir to spartan2>/spartan2")
or do as follows
#find directory of site-packages python -c 'import site; print(site.getsitepackages())' #add \<name\>.pth file in your site-packages directory with string '/<dir to spartan2>/spartan2'
