espm: The Electron Spectro-Microscopy Python Library
This library contains algorithms to perform non-negative matrix factorization with diverse regularisation (e.g. Laplacian or L1) and contraints (e.g. simplex).
It is specialized for Electron Microscopy applications. It contains code to create artificial Energy dispersive X-ray spectroscopy (EDXS) data and to perform hyperspectral unmixing on EDXS spectrum images.
You can install this package from PyPi using:
$ pip install espm
If you want to develop, please use the option:
$ git clone https://github.com/adriente/espm.git $ cd espm $ pip install cython $ pip install -e ".[dev]"
Generate the synthetic dataset. Run the script:
$ python experiments/generate_synthetic_dataset.py

Here is a list of things that we need to do before the version 0.2.0, which will be the first official release of the library. The code is already available on github at the following address: https://github.com/adriente/espm.git A draft of the documentation is available at: https://espm.readthedocs.io/en/latest/
Update the line 40 of doc/introduction/index.rst (@Adrien)
Make some doc for the dataset module (just the minimum) (@Adrien)
Toy dataset: create model class, change outputs, adapts function (@Nati)
- Separate the spectral and spacial parts
Move generate_EDXS_phases to models
Create a modules for weights
Clarify the code for the estimator: remove the L2 loss (@Nati)
Add the general problem that we solve in the doc (@Nati)
Update the ML notebook with more explanations (@Nati)
Check that the doc is somehow understanable and sufficiently complete (@Sebastian)
