鲁棒是Robust的音译,也就是健壮和强壮的意思。它也是在异常和危险情况下系统生存的能力。比如说,计算机软件在输入错误、磁盘故障、网络过载或有意攻击情况下,能否不死机、不崩溃,就是该软件的鲁棒性。所谓“鲁棒性”,也是指控制系统在一定(结构,大小)的参数摄动下,维持其它某些性能的特性。根据对性能的不同定义,可分为稳定鲁棒性和性能鲁棒性。以闭环系统的鲁棒性作为目标设计得到的固定控制器称为鲁棒控制器。

Practical learning-based autonomous driving models must be capable of generalizing learned behaviors from simulated to real domains, and from training data to unseen domains with unusual image properties. In this paper, we investigate transfer learning methods that achieve robustness to domain shifts by taking advantage of the invariance of spatio-temporal features across domains. In this paper, we propose a transfer learning method to improve generalization across domains via transfer of spatio-temporal features and salient data augmentation. Our model uses a CNN-LSTM network with Inception modules for image feature extraction. Our method runs in two phases: Phase 1 involves training on source domain data, while Phase 2 performs training on target domain data that has been supplemented by feature maps generated using the Phase 1 model. Our model significantly improves performance in unseen test cases for both simulation-to-simulation transfer as well as simulation-to-real transfer by up to +37.3\% in test accuracy and up to +40.8\% in steering angle prediction, compared to other SOTA methods across multiple datasets.
