Linfa

linfa (Italian) / sap (English):
The vital circulating fluid of a plant.

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

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, DBSCAN and OPTICS
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
svm	Support Vector Machines	Tested	Supervised learning	Classification or regression analysis of labeled datasets
hierarchical	Agglomerative hierarchical clustering	Tested	Unsupervised learning	Cluster and build hierarchy of clusters
bayes	Naive Bayes	Tested	Supervised learning	Contains Gaussian Naive Bayes
ica	Independent component analysis	Tested	Unsupervised learning	Contains FastICA implementation
pls	Partial Least Squares	Tested	Supervised learning	Contains PLS estimators for dimensionality reduction and regression
tsne	Dimensionality reduction	Tested	Unsupervised learning	Contains exact solution and Barnes-Hut approximation t-SNE
preprocessing	Normalization & Vectorization	Tested	Pre-processing	Contains data normalization/whitening and count vectorization/tf-idf
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!

BLAS/Lapack backend

At the moment you can choose between the following BLAS/LAPACK backends: openblas, netblas or intel-mkl

Backend	Linux	Windows	macOS
OpenBLAS	✔️	-	-
Netlib	✔️	-	-
Intel MKL	✔️	✔️	✔️

For example if you want to use the system IntelMKL library for the PCA example, then pass the corresponding feature:

cd linfa-reduction && cargo run --release --example pca --features linfa/intel-mkl-system

This selects the intel-mkl system library as BLAS/LAPACK backend. On the other hand if you want to compile the library and link it with the generated artifacts, pass intel-mkl-static.
