Diachronic Embedding for Temporal Knowledge Graph Completion

2020 · Proceedings of the AAAI Conference on Artificial Intelligence

Knowledge graphs (KGs) typically contain temporal facts indicating relationships among entities at different times. Due to their incompleteness, several approaches have been proposed to infer new facts for a KG based on the existing ones–a …

Unsupervised Video Object Segmentation for Deep Reinforcement Learning

2018 · arXiv (Cornell University)

We present a new technique for deep reinforcement learning that automatically detects moving objects and uses the relevant information for action selection. The detection of moving objects is done in an unsupervised way by exploiting …
