A Node.js library for machine learning with linear regression and k-means clustering algorithms.
Shaman is a machine learning library for Node.js that implements linear regression and k-means clustering algorithms. It allows developers to build predictive models and perform data clustering directly in JavaScript, supporting both simple and multiple regression with configurable training methods. The library solves the need for accessible statistical modeling tools within the Node.js ecosystem.
Node.js developers and data scientists who need to implement basic machine learning algorithms like regression and clustering in JavaScript without relying on Python or R ecosystems.
Developers choose Shaman for its simplicity and native Node.js integration, offering ready-to-use implementations of fundamental ML algorithms with practical examples and debugging support, reducing the overhead of building these from scratch.

The library offers an intuitive interface for linear regression and k-means, as shown in usage examples where models train with minimal code like new LinearRegression(X,Y).
Supports both Normal Equation and Gradient Descent for linear regression, with customizable iterations and learning rates, allowing optimization for different data scenarios.
Includes debug options to log cost function convergence and track algorithm progress, useful for troubleshooting, as evidenced by the saveCosts and debug parameters.
Comes with real-world examples like car pricing and stock analysis, demonstrating how to apply algorithms in common use cases without extra setup.
Only implements linear regression and k-means clustering, lacking support for classification, dimensionality reduction, or other essential ML techniques.
As a Node.js library, it may not handle large-scale numerical computations efficiently compared to optimized Python or C++ libraries, potentially slowing training on big datasets.
Missing common ML features like regularization, cross-validation, or model serialization, which are needed for robust model development and deployment.
