About
In One Sentence
You trained an SVM using libSVM, now you want the highest possible performance during (real-time) classification, like games or VR.
Highlights
- loads almost all libSVM types (C-SVC, ν-SVC, ε-SVR, ν-SVR) and kernels (linear, poly, RBF and sigmoid)
- produces practically same classification results as libSVM
- optimized for SIMD and can be mixed seamlessly with Rayon
- written in 100% safe Rust
- allocation-free during classification for dense SVMs
- 2.5x - 14x faster than libSVM for dense SVMs
- extremely low classification times for small models (e.g., 128 SV, 16 dense attributes, linear ~ 500ns)
- successfully used in Unity and VR projects (Windows & Android)
Usage
Train with libSVM (e.g., using the tool svm-train), then classify with ffsvm-rust.
From Rust:
// Replace `SAMPLE_MODEL` with a `&str` to your model.
let svm = DenseSVM::try_from(SAMPLE_MODEL)?;
let mut fv = FeatureVector::from(&svm);
let features = fv.features();
features[0] = 0.55838;
features[1] = -0.157895;
features[2] = 0.581292;
features[3] = -0.221184;
svm.predict_value(&mut fv)?;
assert_eq!(fv.label(), Label::Class(42));

Status
- December 14, 2024: After 7+ years, finally ported to stable.🎉🎉🎉
- March 10, 2023: Reactivated for latest Rust nightly.
- June 7, 2019: Gave up on 'no
unsafe', but gained runtime SIMD selection. - March 10, 2019: As soon as we can move away from nightly we'll go beta.
- Aug 5, 2018: Still in alpha, but finally on crates.io.
- May 27, 2018: We're in alpha. Successfully used internally on Windows, Mac, Android and Linux on various machines and devices. Once SIMD stabilizes and we can cross-compile to WASM we'll move to beta.
- December 16, 2017: We're in pre-alpha. It will probably not even work on your machine.
Performance
All performance numbers reported for the DenseSVM. We also have support for SparseSVMs, which are slower
for "mostly dense" models, and faster for "mostly sparse" models (and generally on the performance level of libSVM).
Tips
- Compile your project with
target-cpu=nativefor a massive speed boost (e.g., check our.cargo/config.tomlhow you can easily do that for your project). Note, due to how Rust works, this is only used for application (or dynamic FFI libraries), not library crates wrapping us. - For an x-fold performance increase, create a number of
Problemstructures, and process them with Rayon'spar_iter.

Order: strongest tier first, then most downloads, then name, with unmeasured values last. A library counts downloads over 30 days. An app counts binary downloads per release. An app with none counts its crate downloads over 30 days. ML Rust runs this catalogue, so its closest project always gets a row.

Why ListedNo archive, New or Featured rule places it, so it is Listed.
What it lacks for Featured
- It has 1 active dependents and 0 new dependents in 365 days. Featured needs 11 active dependents or 9 new dependents in 365 days. The repository route reads 79 stars, 11 forks and 2 contributors. It needs 4,539 stars, 434 forks and 79 contributors together.
- The project is dormant and not finished. Dormancy rule
What else the check found
- The last activity is on 14 Dec 2024, 695 days ago. That reaches the 365 days the rules expect, so the project is dormant. Dormancy rule
Not measured: Latest release fails cargo check.
Exact rules: Listed, Featured library. The check on applied thresholds version 9.
