A real-time online machine learning library built on Apache Storm for scalable stream processing with incremental algorithms.
Trident-ML is a real-time online machine learning library built on Apache Storm's Trident framework. It enables developers to implement predictive models that learn incrementally from continuous data streams, such as sensor data, social media feeds, or transaction logs. The library provides algorithms for classification, regression, clustering, and feature preprocessing designed for low-latency, scalable stream processing.
Data engineers and machine learning practitioners building real-time predictive applications on streaming data, particularly those already using or considering Apache Storm for distributed stream processing.
Developers choose Trident-ML for its tight integration with Storm's Trident API, offering a streamlined way to embed machine learning into scalable stream topologies without batch processing. Its incremental algorithms are optimized for speed and memory efficiency, making it suitable for high-velocity data streams.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implements fast online algorithms like Perceptron and AROW that update models with each data point, enabling low-latency predictions on unbounded streams as highlighted in the README.
Built on Apache Storm's Trident abstraction, allowing horizontal scaling across clusters for data preprocessing and stream management, making it ideal for existing Storm pipelines.
Includes tools like the KLD classifier and a pre-trained Twitter sentiment model, providing ready-to-use solutions for NLP tasks on streaming text data.
Computes mean and variance with sliding windows to handle concept drift, offering built-in support for dynamic data environments as demonstrated in the examples.
Only supports linear classifiers, basic regression, and K-Means, lacking non-linear or deep learning algorithms that are essential for complex pattern recognition in modern ML.
The README explicitly states that learning steps cannot be parallelized due to Storm's state update limitations, potentially hindering scalability for high-velocity streams.
Requires familiarity and setup of Apache Storm, adding operational complexity and vendor lock-in compared to standalone or cloud-native ML libraries.
With the last copyright dated 2013-2015 and version 0.0.4, the library may lack active updates, bug fixes, and support for newer Storm or Java versions.
