as_seg: module for computing and segmenting autosimilarity matrices.

Hello, and welcome on this repository!

This project aims at computing autosimilarity matrices, and segmenting them, which consists of the task of structural segmentation.

The current version contains the CBM algorithm [1], along with an implementation of Foote's novelty algorithm [2] based on the MSAF toolbox [3].

It can be installed using pip as pip install as-seg.

This is a first release, and may contain bug. Comments are welcomed!

Tutorial notebook

A tutorial notebook presenting the most important components of this toolbox is available in the folder "Notebooks".

Experimental notebook

Experimental notebooks are available in the folder "Notebooks". They present the code used to compute the main experiments of the paper, in order to improve the reproducibility. Please tell me if any problem would appear when trying to launch them.

Experimental Notebooks requires some pre-computed data to work, which can be found on zenodo: https://zenodo.org/records/10168387. DOI: 10.5281/zenodo.10168386.

Data

Should be obtained from Zenodo: https://zenodo.org/records/10168387. DOI: 10.5281/zenodo.10168386.

Software version

This code was developed with Python 3.8.5, and some external libraries detailed in dependencies.txt. They should be installed automatically if this project is downloaded using pip.
