Rustml

Rustml is a library for doing machine learning in Rust.

The documentation of the project can be found here.

Features

• powerful matrix and vector support with BLAS bindings for high performance
• classification with k-nearest neighbord
• easy access to MNIST database of handwritten digits
• parse and create CSV files
• statistical functions like mean and variance for vectors and matrices
• reading gzip compressed files
• distance metrics

Using rustml - example matrix multplication

Create a new project with cargo:

bash cargo new example --bin

A new directory example is created. Change into this directory and add the following lines Cargo.toml: [dependencies.rustml] git = "https://github.com/daniel-e/rustml/"

or the following dependency: [dependencies] rustml = "*"

Edit the file main.rs in the src directory.

```rust

[macro_use] extern crate rustml;

use rustml::*;

fn main() { let a = mat![ 1.0f32, 2.0; 3.0, 4.0; 5.0, 6.0 ]; let b = mat![ 5.0, 7.0; 6.0, 2.0 ]; let c = (a * b).unwrap();

println!("{}", c);

} ```

Now, in the example directory run the example with cargo run.

Other examples

You can find other examples in the directory examples. These examples can be executed with Cargo as follows:

bash cargo run --example vector_addition cargo run --example mnist_digits cargo run --example matrix_multiplication

Datasets

Rustml comes with the MNIST database of handwritten digits and provides an API to access this database. In prior to use the dataset you have to install it into you home path. This can be easily done as follows:

```bash

download the install script

wget -q https://raw.githubusercontent.com/daniel-e/rustml/master/dldatasets.sh chmod +x dldatasets.sh

download the datasets and install them into ~/.rustml/

./dl_datasets.sh ```
