    Abstract: A substrate shape measuring device, including: a substrate support to support a substrate having a main surface, the main surface of the substrate when supported by the substrate support substantially extending in a first plane; one or more sensor assemblies, each including a light emitter to emit light along a light axis substantially parallel to the first plane and a light sensor arranged to receive the light; and a processing device arranged to determine a shape of the substrate, wherein the substrate shape measuring device is constructed to measure with the one or more sensor assemblies in at least a first measurement direction with respect to the substrate substantially parallel to the first plane and a second measurement direction with respect to the substrate substantially parallel to the first plane.

    Abstract: Method and apparatus for adapting a distribution model of a machine learning fabric. The distribution model is for mitigating the effect of concept drift, and is configured to provide an output as input to a functional model of the machine learning fabric. The functional model is for performing a machine learning task. The method may include obtaining a first data point, and providing the first data point as input to one or more distribution monitoring components of the distribution model. The one or more distribution monitoring components have been trained on a plurality of further data points. A metric representing a correspondence between the first data point and the plurality of further data points is determined, by at least one of the one or more distribution monitoring components. Based on the error metric, the output of the distribution model is adapted.

    Abstract: The present invention relates to a stage system (130), which comprises a pre-exposure element (134), and to a method employing the pre-exposure element for conditioning an optical system (100). The pre-exposure element comprises a radiation receiving area at a surface of the stage system, wherein the radiation receiving area comprises at least one pre-exposure plate configured to receive radiation. The stage system comprises further a controller (140), wherein the controller is capable to control an optical parameter of the pre-exposure element, herewith controlling a portion of received radiation reflected by the pre-exposure element.
