“Know-Evolve: Deep Reasoning in Temporal Knowledge Graphs” Knowledge Graphs are important tools to model multi-relational data that serves as information pool for various applications. Traditionally, these graphs are considered to be static in nature. However, recent availability of large scale event-based interaction data has given rise to dynamically evolving knowledge graphs that contain temporal information for each edge. Reasoning over time in such graphs is not yet well understood. In this paper, we present a novel deep evolutionary knowledge network architecture to learn entity embeddings that can dynamically and non-linearly evolve over time. We further propose a multivariate point process framework to model the occurrence of a fact (edge) in continuous time. To facilitate temporal reasoning, the learned embeddings are used to compute relationship score that further parametrizes intensity function of the point process. We demonstrate improved performance over various existing relational learning models on two large scale real-world datasets. Further, our method effectively predicts occurrence or recurrence time of a fact which is novel compared to any prior reasoning approaches in multi-relational setting.
“Deep EHR: A Survey of Recent Advances on Deep Learning Techniques for Electronic Health Record (EHR) Analysis” The past decade has seen an explosion in the amount of digital information stored in electronic health records (EHR). While primarily designed for archiving patient clinical information and administrative healthcare tasks, many researchers have found secondary use of these records for various clinical informatics tasks. Over the same period, the machine learning community has seen widespread advances in deep learning techniques, which also have been successfully applied to the vast amount of EHR data. In this paper, we review these deep EHR systems, examining architectures, technical aspects, and clinical applications. We also identify shortcomings of current techniques and discuss avenues of future research for EHR-based deep learning.
