Abstract: A device, system, and method are provided for detecting an email phishing attack by training graph neural network to detect phishing emails based on hypertext markup language (HTML) tags and cascading style sheets (CSS) included in an email. Noise is added during the training of the graph neural network to make the trained graph neural networks more robust against small changes in the training data.

Abstract: A method and system are disclosed for determining for a female with irregular menstrual cycles a time interval of fertility, comprising receiving, in a processor (11), from a sensor system (22) of a wearable device (2) of the female, physiological data; determining an estimated time to ovulation of the female, by use of a machine learning model and the physiological data; determining the time interval of fertility using pre-determined time thresholds; and generating a message for the female indicating the time interval of fertility.
