Open Source, Distributed Machine Learning for Everyone
H2O is a fully open source, distributed in-memory machine learning platform with linear scalability. H2O supports the most widely used statistical & machine learning algorithms including gradient boosted machines, generalized linear models, deep learning and more. H2O also has an industry leading AutoML functionality that automatically runs through all the algorithms and their hyperparameters to produce a leaderboard of the best models. The H2O platform is used by over 18,000 organizations globally and is extremely popular in both the R & Python communities.
Key Features of H2O
- Leading Algorithms
- Access from R, Python, Flow and more…
- AutoML (NEW)
- Distributed, In-Memory Processing
- Simple Deployment
Algorithms developed from the ground up for distributed computing and for both supervised and unsupervised approaches including Random Forest, GLM, GBM, XGBoost, GLRM, Word2Vec and many more.
Use the programing language you already know like R, Python and others to build models in H2O, or use H2O Flow, a graphical notebook based interactive user interface that does not require any coding.
H2O’s AutoML can be used for automating the machine learning workflow, which includes automatic training and tuning of many models within a user-specified time limit. Stacked Ensembles will be automatically trained on collections of individual models to produce highly predictive ensemble models which, in most cases, will be the top performing models in the AutoML Leaderboard.
In-memory processing with fast serialization between nodes and clusters to support massive datasets. Distributed processing on big data delivers speeds up to 100x faster with fine-grain parallelism, enabling optimal efficiency without introducing degradation in computational accuracy.
Easy to deploy POJOs and MOJOs to deploy models for fast and accurate scoring in any environment, including very large models.
How it Works
H2O works on existing big data infrastructure, on bare metal or on top of existing Hadoop or Spark clusters. It can ingest data directly from HDFS, Spark, S3, Azure Data Lake or any other data source into it’s in-memory distributed key value store.
Distributed, In-Memory Machine Learning
H2O takes advantage of the computing power of distributed systems and in-memory computing to accelerate machine learning using it’s industry parallelized algorithms which take advantage of fine grained in-memory mapreduce..
Quickly and easily deploy models into production with Java (POJO) and binary formats (MOJO). In addition, H2O models can be productionized in a host of different ways as listed here.
