Abstract: Systems and methods for detecting anomalous integrated circuits (ICs) are provided. An electrical signature for each of multiple reference ICs are created using a resonator. Each IC may be associated with a different model or manufacturer. Later, when an IC that is suspected of being anomalous is received, its signature is generated and compared with a previously generated signature for an IC of the same make and manufacturer. When the signatures differ by more than a threshold amount, then the IC may be determined to be anomalous. In some embodiments, the generated signatures may be used to train a model that can determine whether an IC is anomalous based on its generated signature or can identify the make and manufacturer of an IC based on its generated signature.

Abstract: Systems and methods described herein relate to generating a discrimination scores set based on observation data and action data obtained from a robot trained to perform a task, determining a threshold value based on the discrimination score set, and comparing a discrimination score obtained while the task is being performed with the threshold value to determine if a failure condition is present. This may be performed by utilizing random network distillation or other out-of-distribution detectors and conformal band prediction computed on a set of successful rollouts by the robot.
