cd witzit/
pip install --user --upgrade -r requirements.txt

Usage

HOWTO USE.

Status

Alpha software under development.

Hardware

• SciAps LIBS Analyzer

• SciAps XRF Analyzer

Deep Learning Algorithm

Can use lots from wut.

Amazingly (to me), the paper Classification of radioxenon spectra with deep learning algorithm (2021) by Azimi, et al. uses nearly the identical CNN Sequence() as wut uses, indicating it may be a very good base to start from.

Paper is non-gratis science:

• https://www.sciencedirect.com/science/article/abs/pii/S0265931X21001909

The Sequence() diagram is pulled from the Azimi paper, but is the same as in wut, so makes a good reference.

Will likely work best with binary categorizations. E.g. like this: Is it element A or not element A? Is it element B or not element B? Is it element C or not element C? Not "is it element A, B, or C?"
