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
