1.0.0~alpha0 - 2025-06-29

Initial Alpha Release

We're excited to release the zeroth alpha of Raven, an OCaml machine learning ecosystem bringing modern scientific computing to OCaml.

Added

Core Libraries

• Nx - N-dimensional array library with NumPy-like API

  • Multi-dimensional tensors with support for several data types.
  • Zero-copy operations: slicing, reshaping, broadcasting
  • Element-wise and linear algebra operations
  • Swappable backends: Native OCaml, C, Metal
  • I/O support for images (PNG, JPEG) and NumPy files (.npy, .npz)

• Hugin - Publication-quality plotting library

  • 2D plots: line, scatter, bar, histogram, step, error bars, fill-between
  • 3D plots: line3d, scatter3d
  • Image visualization: imshow, matshow
  • Contour plots with customizable levels
  • Text annotations and legends

• Quill - Interactive notebook environment

  • Markdown-based notebooks with live formatting
  • OCaml code execution with persistent session state
  • Integrated data visualization via Hugin
  • Web server mode for browser-based editing

ML/AI Components

• Rune - Automatic differentiation and JIT compilation framework

  • Reverse-mode automatic differentiation
  • Functional API for pure computations
  • Basic JIT infrastructure (in development)

• Kaun - Deep learning framework (experimental)

  • Flax-inspired functional API
  • Basic neural network components
  • Example implementations for XOR and MNIST

• Sowilo - Computer vision library

  • Image manipulation: flip, crop, color conversions
  • Filtering: gaussian_blur, median_blur
  • Morphological operations and edge detection

Supporting Libraries

• Nx-datasets - Common ML datasets (MNIST, Iris, California Housing)
• Nx-text - Text processing and tokenization utilities

Known Issues

This is an alpha release with several limitations:

• Quill editor has UI bugs being addressed
• APIs may change significantly before stable release
