• Custom Spark-based Linear Model, Generalized Linear Model, and MLP Neural Network algorithms
• Interfaces to Apache SparkML that use the R formula and Distributed Model Matrix infrastructure
• Functions that make use of the expressive R formula object optimized for parallel Spark execution
• Store models and results in HDFS or File System to load and execute in other Big Data clusters, like production

• Use a Big Data Cluster as a high performance compute environment through an R interface
• Make use of HIVE, Impala and SparkSQL to process large datasets from a simplified R API
• Minimize data movement
• Use R packages contributed by the R community
• Integrate data from Oracle Database via OCI and other environments via JDBC

Transparency layer - Leverage R data.frame proxy objects so data remains as HIVE/Impala tables and views. Overloaded R functions translate select R functionality to equivalent SQL for processing in the cluster, taking advantage of parallelism, scalability and security. Data scientists can use familiar R syntax to manipulate database data that remains in the cluster.

Machine Learning Algorithms - R users can take advantage of Oracle Machine Learning for Spark library of parallel distributed algorithms using the R language, in addition to select Spark ML algorithms. Users can specify machine learning models using the familiar R formula syntax. Algorithms support classification, regression, clustering and feature extraction.

Spark Data Frame manipulation - Manage and invoke special functions (including SQL) directly on the Spark Data Frame proxy objects in R, for execution in the cluster. From random sampling and data splits to data listing and printing, the interface offers unique capabilities to manipulate, create and push/pull data into Spark.

OAAgraph - For those interested in leveraging the powerful graph analytics present in Oracle Spatial and Graph, Oracle Machine Learning for Spark is compatible with the package OAAgraph that eases working with both Spark-based machine learning algorithms and the Parallel Graph AnalytiX (PGX) engine. Prepare your data using R in Oracle Machine Learning for Spark, build models and score data to augment graph data and analysis, and compute graph metrics to augment data provided to Spark machine learning algorithms, all with the goal to boost model quality and graph analytics.
