A comprehensive collection of machine learning algorithms implemented exclusively in NumPy for educational purposes and prototyping.
numpy-ml is a machine learning library that implements a wide range of algorithms exclusively using NumPy and the Python standard library. It provides inefficient but legible code for educational purposes and rapid prototyping, covering neural networks, reinforcement learning, linear models, and more. The project solves the need for transparent ML implementations that help users understand underlying mechanics without framework abstractions.
Machine learning students, educators, and researchers who want to understand algorithm internals, as well as developers prototyping ML models who prefer NumPy-based implementations over high-level frameworks.
Developers choose numpy-ml for its educational clarity, comprehensive algorithm coverage, and dependency-light approach. Its unique selling point is implementing everything from scratch with only NumPy, making it ideal for learning and experimentation without black-box dependencies.

All algorithms are implemented from scratch using only NumPy, making the code legible and ideal for understanding ML fundamentals, as emphasized in the project description and README.
Covers a wide range from neural networks and reinforcement learning to linear models and preprocessing, providing a one-stop resource for learning diverse ML techniques, as listed in the available models section.
Relies solely on NumPy and the Python standard library, reducing setup complexity and avoiding black-box dependencies, which is perfect for educational environments and prototyping, as stated in the installation notes.
Offers layers, optimizers, losses, and other components that can be combined to create custom neural network architectures, facilitating experimentation, as detailed in the neural networks section.
Code is designed to be inefficient for clarity, so it's not suitable for performance-critical applications or large-scale datasets, as admitted in the README's description of 'inefficient but somewhat legible' implementations.
Being NumPy-only, it lacks support for GPU acceleration and is not compatible with popular ML frameworks, limiting its use in modern production pipelines that require optimized tools.
Documentation is hosted externally on Read the Docs, which might require additional navigation and could be less integrated than inline documentation, potentially increasing the learning curve for new users.
