allotax 0.2.1

Fast allotaxonometer computation powered by Rust

allotax

Python bindings for allotax-core — fast allotaxonometer computation powered by Rust via PyO3.

Install

pip install allotax

Usage

import allotax

sys1 = {"types": ["word_a", "word_b", "word_c"], "counts": [100.0, 50.0, 25.0]}
sys2 = {"types": ["word_b", "word_c", "word_d"], "counts": [80.0, 40.0, 20.0]}

# Single alpha — lean display result
result = allotax.compute_allotax(sys1, sys2, alpha=1.0)
# result keys: normalization, delta_sum, diamond_counts, max_delta_loss, wordshift, balance, alpha

# Multiple alphas at once (shared combElems step, Rayon-parallelized)
result = allotax.compute_allotax_multi_alpha(sys1, sys2, alphas=[0.5, 1.0, float("inf")])
# result keys: balance, alpha_results

# Full intermediate data (for custom downstream processing)
result = allotax.compute_allotax_full(sys1, sys2, alpha=1.0)
result = allotax.compute_allotax_multi_alpha_full(sys1, sys2, alphas=[0.5, 1.0])

API

Function	Returns
compute_allotax(sys1, sys2, alpha, wordshift_limit=200)	Lean display dict for a single α
compute_allotax_full(sys1, sys2, alpha)	Full intermediate result for a single α
compute_allotax_multi_alpha(sys1, sys2, alphas, wordshift_limit=200)	Lean display dict for multiple α values
compute_allotax_multi_alpha_full(sys1, sys2, alphas)	Full intermediate result for multiple α values
rank_turbulence_divergence(ranks1, ranks2, counts1, counts2, alpha)	RTD only (pre-combined data)

Input systems are plain dicts with "types" (list of str) and "counts" (list of float).
