Crate linfa

Expand description

linfa aims to provide a comprehensive toolkit to build Machine Learning applications with Rust.

Kin in spirit to Python’s scikit-learn, it focuses on common preprocessing tasks and classical ML algorithms for your everyday ML tasks.

Current state

Such bold ambitions! Where are we now? Are we learning yet?

Current state

Where does linfa stand right now? Are we learning yet?

linfa currently provides sub-packages with the following algorithms:

Name	Purpose	Status	Category	Notes
clustering	Data clustering	Tested / Benchmarked	Unsupervised learning	Clustering of unlabeled data; contains K-Means, Gaussian-Mixture-Model and DBSCAN
kernel	Kernel methods for data transformation	Tested	Pre-processing	Maps feature vector into higher-dimensional space
linear	Linear regression	Tested	Partial fit	Contains Ordinary Least Squares (OLS), Generalized Linear Models (GLM)
elasticnet	Elastic Net	Tested	Supervised learning	Linear regression with elastic net constraints
logistic	Logistic regression	Tested	Partial fit	Builds two-class logistic regression models
reduction	Dimensionality reduction	Tested	Pre-processing	Diffusion mapping and Principal Component Analysis (PCA)
trees	Decision trees	Experimental	Supervised learning	Linear decision trees

nn	Nearest Neighbours & Distances	Tested / Benchmarked	Pre-processing	Spatial index structures and distance functions

We believe that only a significant community effort can nurture, build, and sustain a machine learning ecosystem in Rust - there is no other way forward.

If this strikes a chord with you, please take a look at the roadmap and get involved!
