Bryan Cutler created SPARK-19357: ------------------------------------ Summary: Parallel Model Evaluation for ML Pipeline Tuning Key: SPARK-19357 URL: https://issues.apache.org/jira/browse/SPARK-19357 Project: Spark Issue Type: Sub-task Components: ML Reporter: Bryan Cutler
This is a first step of the parent task of Optimizations for ML Pipeline Tuning to perform model evaluation in parallel. A simple approach is to naively evaluate with a possible parameter to control the level of parallelism. There are some concerns with this: * excessive caching of datasets * what to set as the default value for level of parallelism. 1 will evaluate all models in serial, as is done currently. Higher values could lead to excessive caching. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
