Terrain Classification is an essential task in space exploration, where unpredictable environments are difficult to observe using only exteroceptive sensors such as vision. Implementing Neural Network classifiers can have high performance but can be deemed untrustworthy as they lack transparency, which makes them unreliable for taking high-stakes decisions during mission planning. We address this by proposing Neural Networks with Uncertainty Quantification in Terrain Classification. We enable our Neural Networks with Monte Carlo Dropout, DropConnect, and Flipout in time series-capable architectures using only proprioceptive data as input. We use Bayesian Optimization with Hyperband for efficient hyperparameter optimization to find optimal models for trustworthy terrain classification.

在空间探索中，地形分类是一项重要任务，其中无法预测的环境难以仅依靠外部感知传感器（如视觉）进行观测。通过引入神经网络分类器，可以实现高性能，但由于缺乏透明性，这使得它们在任务规划中做出重要决策时不可靠。本文提出了一种带有不确定性量化的神经网络地形分类方法。我们通过在时间序列可用体系结构中使用只有本体感知数据作为输入的蒙特卡洛Dropout、DropConnect和Flipout，使神经网络得以提高。我们使用超带状贝叶斯优化进行高效的超参数优化，以找到值得信赖的地形分类的最佳模型。
