Top 6 H2O-3 alternatives
Scikit-learn is a popular machine learning library in Python that provides simple and efficient tools for data mining and data analysis.
MLlib is Apache Spark's scalable machine learning library for developers building data-processing and predictive-modeling pipelines. It provides distributed algorithms, feature engineering, classification,...
Pros
- Runs machine learning close to distributed Spark data pipelines
- Includes production-oriented pipelines, feature transformers, and evaluators
- Supports large datasets across clusters without moving data to a single machine
Cons
- Less suitable than scikit-learn for small, interactive, single-machine experiments
- Has fewer cutting-edge deep-learning capabilities than TensorFlow or PyTorch
- Requires Spark knowledge and cluster configuration for effective use
Free, open source
