Support Vector Machines

linfa-svm provides a pure Rust implementation for support vector machines.

The Big Picture

linfa-svm is a crate in the linfa ecosystem, an effort to create a toolkit for classical Machine Learning implemented in pure Rust, akin to Python's scikit-learn.

Support Vector Machines are one major branch of machine learning models and offer classification or regression analysis of labeled datasets. They seek a discriminant, which seperates the data in an optimal way, e.g. have the fewest numbers of miss-classifications and maximizes the margin between positive and negative classes. A support vector contributes to the discriminant and is therefore important for the classification/regression task. The balance between the number of support vectors and model performance can be controlled with hyperparameters.

Current State

linfa-svm currently provides an implementation of SVM with Sequential Minimal Optimization:

  • Support Vector Classification with C/Nu/one-class
  • Support Vector Regression with Epsilon/Nu

Examples

There is an usage example in the examples/ directory. To run, use:

$ cargo run --release --example winequality
