Abstract: A computer implemented method trains an image recognition model. A set of processor units creates a saliency map of an original image. The set of processor units superimposes the saliency map on the original image to form an augmented image, wherein the augmented image is used to train the image recognition model.

Abstract: Automatically generating and implementing access policies is provided. An output of a needed user access context to access a resource is obtained from a trained machine learning model based on an extracted attribute of the resource input into the trained machine learning model. The access to the resource by a user is controlled using the output of the needed user access context to access the resource as an access policy for the resource.
