Abstract: Examples provide an autonomous valet parking (AVP) server for a parking lot. The AVP server includes an electronic processor configured to detect that an autonomous vehicle is travelling along a guideline of a first aisle in the parking lot, and detect that the autonomous vehicle is stopped at a first intersection of the parking lot. In response to detecting that the autonomous vehicle is stopped at the first intersection, the electronic processor selects a direction for guiding the autonomous vehicle to an available parking space, and controls a first light projector located at the first intersection to project a first guideline connector that connects the guideline of the first aisle to a guideline of a second aisle in the selected direction. Detection of the first guideline connector by the autonomous vehicle causes the autonomous vehicle to travel along the first guideline connector to the second aisle.

Abstract: A method is for teaching a machine learning system to predict failure probabilities of chips on a wafer. The method is based on a prediction of final test yields depending on wafer-level test measurements by the machine learning system. The machine learning system predicts the failure probabilities of the chips depending on the wafer-level test measurements, and the predicted failure probabilities are aggregated to the predicted final test yields. The machine learning system is trained, such that a math difference between predicted final test yields and final test yields from a training data set is minimized. Differences between the predicted final test yields and final test yields from a training data set are minimized.
