***

### _The library is currently in the early stages of development and is not yet ready for production use._

Concision is designed to be a complete toolkit for building machine learning models in Rust.

Concision is a machine learning library for building powerful models in Rust prioritizing ease-of-use, efficiency, and flexability. The library is built to make use of the 
both the upcoming `autodiff` experimental feature and increased support for generics in the 2024 edition of Rust.

## Getting Started

### Building from the source

Start by cloning the repository

```bash
git clone https://github.com/FL03/concision.git
cd concision
```

```bash
cargo build --features full -r --workspace
```

## Usage

### Example: Linear Model (biased)

```rust
    extern crate concision as cnc;

    use cnc::prelude::{linarr, Linear, Result, Sigmoid};
    use ndarray::Ix2;

    fn main() -> Result<()> {
        tracing_subscriber::fmt::init();
        tracing::info!("Starting linear model example");

        let (samples, d_in, d_out) = (20, 5, 3);
        let data = linarr::<f64, Ix2>((samples, d_in)).unwrap();

        let model = Linear::<f64>::from_features(d_in, d_out).uniform();
        // let model = Linear::<f64, cnc::linear::Unbiased>::from_features(d_in, d_out).uniform();

        assert!(model.is_biased());

        let y = model.activate(&data, Sigmoid::sigmoid).unwrap();
        assert_eq!(y.dim(), (samples, d_out));
        println!("Predictions:\n{:?}", &y);

        Ok(())
    }
```
