PicoGrad: The "Tiny" Autograd Engine

Because size doesn't always matter in ML

PicoGrad is a tiny autograd engine that implements backpropagation (reverse-mode autodiff) over a dynamically built DAG, with a focus on speed and support for distributed tensors. It's a supercharged version of micrograd with a few extra bells and whistles.

We called it "pico" for the same reason you might call your gaming PC a "little setup" – pure, delightful understatement.

Features

• Implements a general-purpose Tensor class that supports distributed computing
• Supports dynamic computational graph construction
• Provides automatic differentiation (autograd) capabilities
• Includes basic neural network building blocks
• Offers graph optimization for improved performance

Extending to Neural Networks

PicoGrad can be used to build, train neural networks and visualize the computational graph.

Distributed Tensor Support

PicoGrad goes beyond micrograd by supporting distributed tensors, allowing for efficient computation on large datasets:

from picograd.engine import DistributedTensor
import numpy as np

data = DistributedTensor(np.random.rand(1000000, 1000))
print(data)

Graph Optimization

PicoGrad includes graph optimization techniques to improve computational efficiency:
