hypercube-rc 0.2.0

Python bindings for HypercubeRC: reservoir computing on Boolean hypercube graphs

HypercubeRC

Python bindings for reservoir computing on Boolean hypercube graphs.

The reservoir topology is a Boolean hypercube of dimension DIM, giving N = 2^DIM neurons (DIM 5-12, i.e. 32 to 4096 neurons). All connectivity is defined by XOR operations on vertex indices -- no adjacency list stored. Scale-invariant hyperparameters: the same SR and input_scaling work at every DIM.

Installation

pip install hypercube-rc

Pre-built wheels for Python 3.10-3.13 on Windows (x64), Linux (x86_64, aarch64), and macOS (x86_64, arm64). No compiler required.

Quick Start

import numpy as np
import hypercube_rc as hrc

# One-step-ahead sine prediction
signal = np.sin(np.linspace(0, 20 * np.pi, 2000)).astype(np.float32)
esn = hrc.ESN(dim=7, seed=42)
esn.fit(signal, warmup=200)
print(f"R2 = {esn.r2():.6f}")      # R2 = 0.999999
print(f"NRMSE = {esn.nrmse():.6f}") # NRMSE = 0.000129

Features

• Simple API -- fit() handles warmup, run, and train in one call
• DIM 5-12 -- 32 to 4096 neurons, scale-invariant defaults
• Two readouts -- Ridge regression (closed-form optimal) and Linear SGD (streaming)
• Multi-input -- multiple input channels via stride-interleaved driving
• Streaming mode -- incremental weight updates for real-time applications
• Model persistence -- pickle, save/load to disk
• Translation layer -- [x | x^2 | x*x'] feature expansion for 2.5x features
