Graph-native vector search.
Spectral generative models.

We build ArrowSpace, a Rust engine that indexes embeddings as signal graphs and searches them through graph Laplacians and per-feature energy dispersion. Around it we maintain Python bindings, release-gated benchmarks, diffusion models for sound, and the SmartCore machine-learning library.

Flagship

ArrowSpace — vectors as graphs

ArrowSpace treats embeddings as signals on a graph. Search walks a graph Laplacian guided by λED, an energy-dispersion network over features. Results then respect dataset structure, not only distance. Graph analysis, vector search, and energy-distribution stats ship in one package.

arrowspace-rs

Core engine in Rust. Builds λτ-indexed signal graphs and serves dispersion-model analytics and search for your vectors.

Generative audio

Latent Sound Diffusion

LSD is a latent diffusion model for sound production. A frozen ArrowSpace prior (LF, λED) defines the semantic manifold. An EnCodec encoder produces one-dimensional audio latents. Diffusion runs on those latents while a trainable graph decoder reconstructs waveforms on the feature-space manifold.

The model is a tool for producers, not a research claim. Train fast on your own samples. Every run differs by design: seeds stay fresh and latent noise injection is a taste knob.
