Navigating Rifts in Human-LLM Grounding: Study and Benchmark

ACL 2025long

Language models excel at following instructions but often struggle with the collaborative aspects of conversation that humans naturally employ. This limitation in grounding—the process by which conversation participants establish mutual understanding—can lead to outcomes ranging from frustrated user…

When to Show a Suggestion? Integrating Human Feedback in AI-Assisted Programming

AAAI 2024technical

AI powered code-recommendation systems, such as Copilot and CodeWhisperer, provide code suggestions inside a programmer's environment (e.g., an IDE) with the aim of improving productivity. We pursue mechanisms for leveraging signals about programmers' acceptance and rejection of code suggestions to…

Effective Human-AI Teams via Learned Natural Language Rules and Onboarding

NeurIPS 2023spotlight

People are relying on AI agents to assist them with various tasks. The human must know when to rely on the agent, collaborate with the agent, or ignore its suggestions. In this work, we propose to learn rules grounded in data regions and described in natural language that illustrate how the human sh…

In Defense of Softmax Parametrization for Calibrated and Consistent Learning to Defer

NeurIPS 2023poster

Enabling machine learning classifiers to defer their decision to a downstream expert when the expert is more accurate will ensure improved safety and performance. This objective can be achieved with the learning-to-defer framework which aims to jointly learn how to classify and how to defer to the e…

Who Should Predict? Exact Algorithms For Learning to Defer to Humans

AISTATS 2023poster

Automated AI classifiers should be able to defer the prediction to a human decision maker to ensure more accurate predictions. In this work, we jointly train a classifier with a rejector, which decides on each data point whether the classifier or the human should predict. We show that prior approach…

Sample Efficient Learning of Predictors that Complement Humans

ICML 2022spotlight

One of the goals of learning algorithms is to complement and reduce the burden on human decision makers. The expert deferral setting wherein an algorithm can either predict on its own or defer the decision to a downstream expert helps accomplish this goal. A fundamental aspect of this setting is the…

Teaching Humans When to Defer to a Classifier via Exemplars

AAAI 2022technical

Expert decision makers are starting to rely on data-driven automated agents to assist them with various tasks. For this collaboration to perform properly, the human decision maker must have a mental model of when and when not to rely on the agent. In this work, we aim to ensure that human decision m…
