A Python implementation of theFuzzTX (Fuzzy Temporal Crossing) algorithm. The algorithm applies a fuzzy triangular membership function to cross time-series data from different and/or unrelated sources based on thedate-time attributes.Research paper was accepted as a conference paper at the 2020 ADBIS, TPDL & EDA joint conferences:

You will be required to install the following python dependencies before usingFuzzTX algorithm:
install python (version => 3.6)$ pip3 install numpy python-dateutil scikit-fuzzy
Use it a command line program with the local package:
$python3 src/init_fuzztx_csv.py -a allowChar -f'file1.csv,file2.csv,file3.csv'
where you specify the input parameters as follows:
files.csv - [required] files in csv format separated by commas
allowChar - [optional] allow characters
default = 0. If set to 1, the algorithm will cross all columns including those that have non-numeric values.
For example we executed theFuzzTX algorithm on sample data-sets
$python3 src/init_fuzztx_csv.py -a 0 -f'../data/oreme/GPS.csv,../data/oreme/Omnidir.csv'
The output should be a generated csv file(x_data.csv). For purposes of demonstration, we display the contents (as a nested array) below
