摘要:

本文涉及实现高效的信息理论机器人探索与所需的性能在复杂的场景。我们建立了一个连续的轻量级推理模型来预测的互信息(MI)和相关的预测置信度的机器人的候选动作没有被显式评估。这使得机器人探索中的决策阶段可以近似以对数复杂度运行,这也将有利于在大型非结构化和混乱的地方进行在线探索,这些地方需要更多的空间样本来评估和决定。我们还开发了一个目标函数来平衡具有最高MI值的局部最优行动和具有高预测方差的全局选择。大量的数值和数据集模拟表明,我们所提出的方法在不同的环境中不失去探索性能的期望效率。我们还为机器人社区提供在GitHub上发布的开源实现代码。

英文摘要:

This paper concerns realizing highly efficient information-theoretic robot exploration with desired performance in complex scenes. We build a continuous lightweight inference model to predict the mutual information (MI) and the associated prediction confidence of the robot's candidate actions which have not been evaluated explicitly. This allows the decision-making stage in robot exploration to run with a logarithmic complexity approximately, this will also benefit online exploration in large unstructured, and cluttered places that need more spatial samples to assess and decide. We also develop an objective function to balance the local optimal action with the highest MI value and the global choice with high prediction variance. Extensive numerical and dataset simulations show the desired efficiency of our proposed method without losing exploration performance in different environments. We also provide our open-source implementation codes released on GitHub for the robot community.
