padic-ml

WORK IN PROGRESS. Paper code is being refactored into this library. Thanks for your patience!

This is a JAX library for differentiable training of p-adic neural networks, implementing methods described in Continuous Optimization for p-adic Models (arXiv 2026).

Install with pip install padic-ml.

PArray is an array primitive for "learnable" p-adic numbers (points in the p-adic injective hull $\Gamma_p$ in Berkovich space).

With radius 0 (no second argument), these become ordinary p-adic numbers $\mathbb{Q}_p$.

>>> import padic_ml as pml
>>> p1 = pml.array([3, 4], radius=[1, 3], p=3)
>>> p2 = pml.array([7, 1], p=3)
>>> p1*p2
PArray(unit=Array([7, 4], dtype=int32), valuation=Array([1, 0], dtype=int32), log_radius=Array([0., 1.], dtype=float32), p=3)
