Crates.io docs License

A Rust crate for building and training neural networks. tinygrad provides a simple interface for defining tensors, performing forward and backward passes, and implementing basic operations such as dot products and summation.

🚀 Quick Start

Get started with the tinygrad library by following these simple steps:

  1. Install the tinygrad crate by adding the following line to your Cargo.toml file:
[dependencies]
tinygrad = "0.1.0"
  1. Use the Tensor and ForwardBackward traits to create and work with tensors:
use ndarray::{array, Array1};
use tinygrad::{Tensor, Context, TensorTrait};

// Create a tensor
let value = array![1.0, 2.0, 3.0];
let tensor = Tensor::new(value);

// Perform forward and backward passes
let mut ctx = Context::new();
let result = tensor.forward(&mut ctx, vec![tensor.get_value()]);
tensor.backward(&mut ctx, array![1.0, 1.0, 1.0].view());
  1. Implement custom operations by defining structs that implement the ForwardBackward trait:
use ndarray::ArrayView1;
use tinygrad::{ForwardBackward, Context, TensorTrait};

// Example operation: Dot product
struct Dot;

impl ForwardBackward for Dot {
    fn forward(&self, _ctx: &mut Context, inputs: Vec<ArrayView1<f64>>) -> f64 {
        let input = &inputs[0];
        let weight = &inputs[1];
        input.dot(weight)
    }

    fn backward(&self, ctx: &mut Context, grad_output: ArrayView1<f64>) {
        // Implement backward pass
        // ...
    }
}

🔧 Usage Example

use ndarray::{array, Array1};
use tinygrad::{Tensor, Context, TensorTrait};

fn main() {
    let input = array![1.0, 2.0, 3.0];
    let weight = array![4.0, 5.0, 6.0];

    let input_tensor = Box::new(Tensor::new(input));
    let weight_tensor = Box::new(Tensor::new(weight));

    let dot_fn = Dot;
    let mut ctx = Context::new();

    let inputs = vec![
        input_tensor.get_value(),
        weight_tensor.get_value(),
    ];
    let output = dot_fn.forward(&mut ctx, inputs);

    println!("Dot product: {:?}", output);

    let grad_output = array![1.0, 1.0, 1.0];
    dot_fn.backward(&mut ctx, grad_output.view());

    let grad_input = &input_tensor.grad.clone();
    let grad_weight = &weight_tensor.grad.clone();

    println!("Gradient for input: {:?}", grad_input);
    println!("Gradient for weight: {:?}", grad_weight);
}
