PERSIMMON: a visual dataflow language for machine learning

Abstract

Persimmon is a visual programming interface that leverages scikit-learn to provide a drag and drop interface for developing Machine Learning and Data Mining pipelines. It is based on the dataflow programming principles, giving the user a functional visual language with a type safety system that checks connections at write time, non-strict evaluation, task parallelization, and execution visualization. It has been evaluated by participants on a three-task form, overall receiving good reviews, being praised by the use of colors to indicate types, consistent design, easy to navigate and shallow learning curve.
