uhg 0.1.3

Universal Hyperbolic Geometry Library for PyTorch

Universal Hyperbolic Geometry Library

A PyTorch library for Universal Hyperbolic Geometry (UHG) and Hyperbolic Graph Neural Networks. All operations are performed directly in hyperbolic space without tangent space mappings.

Installation

Basic Installation

pip install uhg

With GPU Support

pip install uhg[gpu]

CPU-Only Version

pip install uhg[cpu]

Development Version

pip install uhg[dev]

Documentation Tools

pip install uhg[docs]

Quick Start

import uhg
import torch

# Create hyperbolic tensors
manifold = uhg.LorentzManifold()
x = uhg.HyperbolicTensor([1.0, 0.0, 0.0], manifold=manifold)
y = uhg.HyperbolicTensor([0.0, 1.0, 0.0], manifold=manifold)

# Compute hyperbolic distance
dist = uhg.distance(x, y)

# Create a hyperbolic neural network
model = uhg.nn.layers.HyperbolicGraphConv(
    manifold=manifold,
    in_features=10,
    out_features=5
)

# Use hyperbolic optimizer
optimizer = uhg.optim.HyperbolicAdam(
    model.parameters(),
    manifold=manifold,
    lr=0.01
)
