Abstract

Autonomous systems have to understand the environment and make the right decisions. Current autonomous systems often focus on hand-crafted rules or purely learned models from a limited amount of biased data. Learning the semantic information of the surroundings and obtaining knowledge from humans are essential for autonomous systems. To meet this goal, we propose the situation aware system, an autonomous system that can actively learn from the environment by incorporating human knowledge to make trustworthy decisions and discover novel events. We explore the situation learning strategies to bridge models, data, and knowledge for reliable and predictable situation awareness systems.

This study topic specifically explores the learning for situation awareness from three different angles (DUR: Diversity, Uncertainty, and Reliability):

  1. Multi-sensor and multi-modality representation learning (Diversity). Multiple sensors with different modalities can be installed in the autonomous systems. In some cases, the system can also access to the data captured by environment. How to mine the useful semantic information from noisy data and collaborate with different sources and modalities for representation learning is in high demand.
  2. Learning for rare and unseen situation discovery (Uncertainty). Humans have a good sense of danger discovery in the environment even if the situation has never happened before. The ability of discovering the rare and unseen situation is important for autonomous systems. Situation learning for novelty discovery, anomaly detection, and out-of-distribution generalization should be much enhanced in future autonomous systems.
  3. Learning for trustworthy and explainable systems (Reliability). Reasoning is highly required in future autonomous systems. The decisions by the system should be explainable to humans. To realize this goal, the system should take account of priors of the situation, the common knowledges of humans, and the latent causality from input to output. With the combination of data, knowledge and reasoning, autonomous systems can become trustworthy and explainable in the decision making.
