Jared Dunnmon

I am currently a postdoctoral researcher with Chris Ré at Stanford.

My research focuses on developing weakly supervised machine learning systems to support applications in areas such as medicine, energy and environment, and intelligence analysis wherein the costs of failure are high and labeled data is scarce.

By modeling noisy, programmatic sources of supervision applied to unlabeled data, directly integrating human domain knowledge, and leveraging related tasks, my work aims to enable reliable application of state-of-the-art machine learning models to these problems with the speed, scale, and performance levels required for practical deployment.

Projects

Snorkel is a system for rapidly creating, modeling, and managing training data by leveraging a variety of weak supervision sources in a principled manner. Today's state-of-the-art machine learning models require massive labeled training sets, which usually do not exist for real-world applications.

Particularly complex problems are often composed of multiple tasks, and may have many different types of weak supervision that provide labels for one or more of these tasks. In Snorkel MeTaL, we use a new modeling approach to denoise this massively multi-task weak supervision before training an auto-compiled multi-task neural network.
