    Abstract: A method, a computerized apparatus and a computer program product for adaptive learning for image classification. The method comprises applying a set of classification models on a calibration dataset and on a production dataset, and calculating disagreement measurements over the predictions thereof on each dataset. Based on similarity measurement between the disagreement measurement of the calibration and the production datasets, being below a predetermined threshold, a data drift is indicated in the production dataset. The method further comprises determining a training dataset for training a classification model for the production dataset. The training dataset is selected over a plurality of sets of images ordered according to time intervals in which images therein are obtained. The selection is performed based on weights determined for the plurality of sets.

    Abstract: Optical apparatus includes a mount, which holds a workpiece. An array of optical heads project respective patterns of radiation onto the workpiece. A calibration assembly captures images of the respective patterns. A motion assembly, on which the calibration assembly is mounted, transports the calibration assembly among a plurality of different positions between the array of the optical heads and the mount so as to intercept and image, at each of the different positions, a respective pattern projected by a different one of the optical heads. A processor processes the images captured by the calibration assembly at the different positions so as to monitor operation of the apparatus.

    Abstract: A method for fabricating a semiconductor device includes providing a layer of a semiconductor material on at least a portion of a surface of a substrate, and forming along the surface a capillary structure, which is in communication with the semiconductor material but is at least partially empty of the semiconductor material. The semiconductor material is heated, so as to cause the semiconductor material to melt and flow into the capillary structure. Upon allowing the semiconductor material to cool, a crystal is seeded in the capillary structure and spreads from the capillary structure through an area of the semiconductor material.
