摘要:

主动推理是一种支持生物主体在现实世界中感知和行动的理论。主动推理的核心是基于大脑是一个近似贝叶斯推理引擎的原则,建立一个内部生成模型,以驱动代理实现最小的惊喜。虽然这一理论已经在认知神经科学的基础上显示出有趣的结果,但它的应用仍然局限于小的、预定义的传感器和状态空间的模拟。在本文中,我们利用深度学习的最新进展来构建更复杂的生成模型,这些模型可以在没有预定义状态空间的情况下工作。状态表示是从真实世界的高维感知数据(如摄像机帧)中端到端学习的。我们还表明,这些生成模型可以用来从事积极的推理。据我们所知,这是深度主动推理在现实世界机器人导航任务中的首次应用。

英文摘要:

Active inference is a theory that underpins the way biological agent's perceive and act in the real world. At its core, active inference is based on the principle that the brain is an approximate Bayesian inference engine, building an internal generative model to drive agents towards minimal surprise. Although this theory has shown interesting results with grounding in cognitive neuroscience, its application remains limited to simulations with small, predefined sensor and state spaces. In this paper, we leverage recent advances in deep learning to build more complex generative models that can work without a predefined states space. State representations are learned end-to-end from real-world, high-dimensional sensory data such as camera frames. We also show that these generative models can be used to engage in active inference. To the best of our knowledge this is the first application of deep active inference for a real-world robot navigation task.
