Debugging Machine Learning Pipelines
Machine learning tasks entail the use of complex computational pipelines to
reach quantitative and qualitative conclusions. If some of the activities in a
pipeline produce erroneous or uninformative outputs, the pipeline may fail or
produce incorrect results. Inferring the root cause of failures and unexpected
behavior is challenging, usually requiring much human thought, and is both
time-consuming and error-prone. We propose a new approach that makes use of
iteration and provenance to automatically infer the root causes and derive
succinct explanations of failures. Through a detailed experimental evaluation,
we assess the cost, precision, and recall of our approach compared to the state
of the art. Our source code and experimental data will be available for
reproducibility and enhancement.Comment: 10 page
