摘要:

将神经网络结合到粒子滤波器中的最新进展提供了在大规模现实世界应用中应用粒子滤波器所需的灵活性。在这个框架中的动态和测量模型是通过粒子滤波器的微分实现学习。过去在优化这种模型方面的努力通常需要了解真实状态,这可能是昂贵的,甚至在实践中无法获得。在本文中,为了减少对注释数据的需求,我们提出了一个端到端的学习目标的基础上最大化的伪似然函数,可以提高估计的状态时,大部分的真实状态是未知的。我们评估所提出的方法在机器人状态估计任务与模拟和真实世界的数据集的性能。

英文摘要:

Recent advances in incorporating neural networks into particle filters provide the desired flexibility to apply particle filters in large-scale real-world applications. The dynamic and measurement models in this framework are learnable through the differentiable implementation of particle filters. Past efforts in optimising such models often require the knowledge of true states which can be expensive to obtain or even unavailable in practice. In this paper, in order to reduce the demand for annotated data, we present an end-to-end learning objective based upon the maximisation of a pseudo-likelihood function which can improve the estimation of states when large portion of true states are unknown. We assess performance of the proposed method in state estimation tasks in robotics with simulated and real-world datasets.
