coaster-NN provides Neural Network related algorithms for coaster. Run NN operations on servers, desktops or mobiles, GPUs, FPGAs or CPUS, without carrying about OpenCL or CUDA support on the machine.

coaster-NN was started as collenchyma-NN at Autumn to support the Machine Intelligence Framework Leaf with backend-agnostic, state-of-the-art performance.

Today it powers Juice.

Provided Operations

This Plugins provides the following operations to the coaster Backend. Every Operation includes forward + backward. A - means not yet implemented. More information can be found in the Documentation.

Operation CUDA OpenCL Native
Sigmoid cuDNN v5 or later - Rust
SigmoidPointwise cuDNN v5 or later - Rust
ReLU cuDNN v5 or later - Rust
ReLUPointwise cuDNN v5 or later - Rust
Tanh cuDNN v5 or later - Rust
TanhPointwise cuDNN v5 or later - Rust
Normalization (LRN) cuDNN v5 or later - -
Convolution cuDNN v5 or later - Rust(forward)
Softmax cuDNN v5 or later - Rust
LogSoftmax cuDNN v5 or later - Rust
Pooling Max cuDNN v5 or later - Rust(forward)
Pooling Avg cuDNN v5 or later - -

Kudos to ehiggs, for implementing the initial native Rust operations.

Getting Started

If you're using Cargo, just add coaster-NN to your Cargo.toml:

[dependencies]
coaster = "0.1.0"
coaster-nn = "0.4.0"

If you're using Cargo Edit, you can call:

$ cargo add coaster-nn

Usage

Bring the Plugin trait and the other important coaster traits/structs in scope and you will be able to execute the here provided operations on your coaster Backend.

extern crate coaster as co;
extern crate coaster_nn as nn;
use co::prelude::*;
use nn::*;
fn main() {
    // Initialize a CUDA Backend.
    let backend = Backend::<Cuda>::default().unwrap();
    // Initialize two SharedTensors.
    // Usually you would want also fill them with data.
    // More infos about that in the coaster README.md
    let mut x = SharedTensor::<f32>::new(backend.device(), &(1, 1, 3)).unwrap();
    let mut result = SharedTensor::<f32>::new(backend.device(), &(1, 1, 3)).unwrap();
    // Use the operation provided by this Plugin.
    backend.sigmoid(&mut x, &mut result);
}
