# CARS Data

CARS Data is a package providing multivariate curve resolution algorithms and utilities functions for CARS cartographies.
The package provides: 
* a Simplisma algorithm implementation
* MCR-ALS based on [pymcr](https://pages.nist.gov/pyMCR/) package:
  * ALS and NNLS regressions
  * the classical normalization (sum-to-one) and non-negative constraints
  * a new segmentation constraint based on Chan-Sandberg-Vese algorithm
* fit unknown spectra onto fixed signature spectra using ALS or NNLS and apply MCR constraints on the results
* Autoencoders based on [PyTorch](https://pytorch.org/) packages.
