摘要:

人工智能体的感知是人工智能研究的重大挑战之一。深度学习和数据驱动的方法在约束问题上是成功的,在这些问题上,感知可以通过监督来学习,但不能扩展到开放世界。在这种情况下,对于具有第一人称传感器的自主具身智能体,可以端到端地学习感知以解决特定任务。然而,文献表明,感知不是一个纯粹的被动压缩机制,行动在抽象表征的形成中发挥着重要作用。我们建议研究这些具身智能体的感知,在数学形式主义的群论,以使感知和行动之间的联系。特别是,我们认为连续的动作序列的交换属性,这样一个具体的代理感知到的感官信息。我们介绍了感官交换概率(SCP)标准,衡量有多少代理的自由度影响环境中体现的情况。我们将展示如何在不同的环境中计算这个标准,包括现实的机器人设置。我们经验性地说明了SCP和动作序列的交换属性如何用于学习环境中的对象并提高强化学习中的样本效率。

英文摘要:

Perception of artificial agents is one the grand challenges of AI research. Deep Learning and data-driven approaches are successful on constrained problems where perception can be learned using supervision, but do not scale to open-worlds. In such case, for autonomous embodied agents with first-person sensors, perception can be learned end-to-end to solve particular tasks. However, literature shows that perception is not a purely passive compression mechanism, and that actions play an important role in the formulation of abstract representations. We propose to study perception for these embodied agents, under the mathematical formalism of group theory in order to make the link between perception and action. In particular, we consider the commutative properties of continuous action sequences with respect to sensory information perceived by such an embodied agent. We introduce the Sensory Commutativity Probability (SCP) criterion which measures how much an agent's degree of freedom affects the environment in embodied scenarios. We show how to compute this criterion in different environments, including realistic robotic setups. We empirically illustrate how SCP and the commutative properties of action sequences can be used to learn about objects in the environment and improve sample-efficiency in Reinforcement Learning.
