Cetana

An advanced machine learning library empowering developers to build intelligent applications with ease, written in Rust.

Features • Examples • Roadmap

Cetana (चेतन) is a Sanskrit word meaning "consciousness" or "intelligence," reflecting the library's goal of bringing machine intelligence to your applications.

Cetana is a Rust-based machine learning library designed to provide efficient and flexible machine learning operations across multiple compute platforms. It focuses on providing a clean, safe API while maintaining high performance and memory safety.

• Type-safe Tensor Operations - Memory-safe tensor operations with compile-time guarantees
• Neural Network Building Blocks - Complete set of layers for building complex networks
• Automatic Differentiation - Seamless gradient computation and backpropagation
• Model Serialization - Save and load trained models with ease
• Multiple Activation Functions - ReLU, Sigmoid, Tanh, and more
• Optimizers & Loss Functions - MSE, Cross Entropy, Binary Cross Entropy
• Multi-Platform Support - CPU backend with GPU acceleration planned

use cetana::tensor::{Tensor, Device};

// Create tensors
let a = Tensor::new(&[1.0, 2.0, 3.0, 4.0], &[2, 2], Device::CPU)?;
let b = Tensor::new(&[5.0, 6.0, 7.0, 8.0], &[2, 2], Device::CPU)?;

// Perform operations
let c = a.add(&b)?;
let d = a.matmul(&b)?;

println!("Addition: {:?}", c);
println!("Matrix multiplication: {:?}", d);

use cetana::nn::{Sequential, Linear, ReLU, MSELoss};
use cetana::optimizer::SGD;

// Create a simple neural network
let model = Sequential::new()
    .add(Linear::new(10, 64)?)
    .add(ReLU::new())
    .add(Linear::new(64, 1)?);

// Define loss function and optimizer
let loss_fn = MSELoss::new();
let optimizer = SGD::new(0.01);

// Training loop
for epoch in 0..100 {
    let output = model.forward(&input)?;
    let loss = loss_fn.compute(&output, &target)?;
    
    model.backward(&loss)?;
    optimizer.step(&model)?;
}

use cetana::model::{save_model, load_model};

// Save trained model
save_model(&model, "my_model.cetana")?;

// Load model later
let loaded_model = load_model("my_model.cetana")?;

Add Cetana to your Cargo.toml:

[dependencies]
cetana = "0.1.0"

use cetana::tensor::Tensor;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create your first tensor
    let tensor = Tensor::new(&[1.0, 2.0, 3.0], &[3], cetana::tensor::Device::CPU)?;
    println!("Hello from Cetana: {:?}", tensor);
    Ok(())
}
