Conformal Policy Learning for Sensorimotor Control Under Distribution Shifts

no code implementations2 Nov 2023 Huang Huang, Satvik Sharma, Antonio Loquercio, Anastasios Angelopoulos, Ken Goldberg, Jitendra Malik

The key idea is the design of switching policies that can take conformal quantiles as input, which we define as conformal policy learning, that allows robots to detect distribution shifts with formal statistical guarantees.

Autonomous Driving Conformal Prediction

Learned, Uncertainty-driven Adaptive Acquisition for Photon-Efficient Multiphoton Microscopy

no code implementations24 Oct 2023 Cassandra Tong Ye, Jiashu Han, Kunzan Liu, Anastasios Angelopoulos, Linda Griffith, Kristina Monakhova, Sixian You

Finally, with our adaptive acquisition technique, we demonstrate a 120X reduction in acquisition time and total light dose while successfully recovering fine features in the sample.

Optimal Data Selection: An Online Distributed View

1 code implementation25 Jan 2022 Mariel Werner, Anastasios Angelopoulos, Stephen Bates, Michael I. Jordan

The blessing of ubiquitous data also comes with a curse: the communication, storage, and labeling of massive, mostly redundant datasets.

Distribution-Free, Risk-Controlling Prediction Sets

3 code implementations7 Jan 2021 Stephen Bates, Anastasios Angelopoulos, Lihua Lei, Jitendra Malik, Michael I. Jordan

While improving prediction accuracy has been the focus of machine learning in recent years, this alone does not suffice for reliable decision-making.
