  We explore trust in a relatively new area of data science: Automated Machine
Learning (AutoML). In AutoML, AI methods are used to generate and optimize
machine learning models by automatically engineering features, selecting
models, and optimizing hyperparameters. In this paper, we seek to understand
what kinds of information influence data scientists' trust in the models
produced by AutoML? We operationalize trust as a willingness to deploy a model
produced using automated methods. We report results from three studies --
qualitative interviews, a controlled experiment, and a card-sorting task -- to
understand the information needs of data scientists for establishing trust in
AutoML systems. We find that including transparency features in an AutoML tool
increased user trust and understandability in the tool; and out of all proposed
features, model performance metrics and visualizations are the most important
information to data scientists when establishing their trust with an AutoML
tool.
