Symbolic (Weighted) Automata Monitoring

This project implements different automata I use in my research, including nondeterministic weighted automata and alternating weighted automata.

Differentiable Automata in JAX

The automatix.nfa module implements differentiable automata in JAX, along with automatix.algebra.semiring.jax_backend. Specifically, it does so by defining matrix operators on the automata transitions, which can then be interpreted over a semiring to yield various acceptance and weighted semantics.

Alternating Automata as Ring Polynomials

The automatix.afa module implements weighted alternating finite automata over algebra defined in automatix.algebra.semiring.

Using the project

If you are just using it as a library, the Git repository should be installable pretty easily using

pip install git+https://github.com/anand-bala/automatix

If you want develop the project, you will need to install Pixi. Once you install it for you platform, you can install the project development dependencies and the current project as an editable install using:

pixi install -e dev

Then, you can use the following command to activate the pixi environment:

pixi shell -e dev

From here, you can look into the examples folder for some examples, and generally hack away at the code.
