Graph Neural Networks (GNNs) have recently become increasingly popular due to their ability to learn complex systems of relations or interactions arising in a broad spectrum of problems ranging from biology and particle physics to social networks and recommendation systems. Despite the plethora of different models for deep learning on graphs, few approaches have been proposed thus far for dealing with graphs that present some sort of dynamic nature (e.g. evolving features or connectivity over time). In this paper, we present Temporal Graph Networks (TGNs), a generic, efficient framework for deep learning on dynamic graphs represented as sequences of timed events. Thanks to a novel combination of memory modules and graph-based operators, TGNs are able to significantly outperform previous approaches being at the same time more computationally efficient. We furthermore show that several previous models for learning on dynamic graphs can be cast as specific instances of our framework. We perform a detailed ablation study of different components of our framework and devise the best configuration that achieves state-of-the-art performance on several transductive and inductive prediction tasks for dynamic graphs.Preprint.

The authors present empirical data on therapeutic hypnosis and brief psychotherapy as a 4-Stage Creative Process of focused attention and positive expectancy in professional training workshops of the American Society of Clinical Hypnosis, the National Institute for the Clinical Applications of Behavioral Medicine, and the Milton H. Erickson Foundation. The authors developed a brief protocol for assessing the 4-Stage Creative Process, which is the core dynamic of the Creative Psychosocial Genomic Healing Experience. They report that the 4-Stage Creative Process for resolving many psychological problems and symptomatic behavior in a satisfactory manner can be learned within 3 trials during 2-day professional workshops. The theory, research, and practice of private problem solving, stress reduction, and mind-body symptom resolution in professional and public settings is discussed. Immediate knowledge of results, positive peer support, and the development of new psychosocial skills in learning how to appropriately communicate live here-and-now novel and numinous experiences is an exhilarating exercise in creating new consciousness that facilitates the confidence and maturation of psychotherapists.
