论文摘要
随着人工智能和自主学习的增长阶段,自动驾驶汽车是研究的有前途的领域之一,并成为汽车行业的重点中心。行为克隆是通过机器学习算法通过视觉运动策略复制人类行为的过程。近年来,基于转移学习的概念,已经在自动驾驶汽车的背景下开发了几种基于学习的行为克隆方法。关于这一点,本文提出了使用VGG16体系结构进行转移学习方法,该方法通过重新调整最后一个块,同时将其他块保持不可训练,从而进行了微调。进一步将提议的体系结构的性能与现有的NVIDIA架构及其修剪变体进行比较(使用1x1滤波器修剪22.2%和33.85%,以减少参数总数)。实验结果表明,带有转移学习体系结构的VGG16的表现优于其他讨论的方法,其收敛速度更快。
With the growing phase of artificial intelligence and autonomous learning, the self-driving car is one of the promising area of research and emerging as a center of focus for automobile industries. Behavioral cloning is the process of replicating human behavior via visuomotor policies by means of machine learning algorithms. In recent years, several deep learning-based behavioral cloning approaches have been developed in the context of self-driving cars specifically based on the concept of transfer learning. Concerning the same, the present paper proposes a transfer learning approach using VGG16 architecture, which is fine tuned by retraining the last block while keeping other blocks as non-trainable. The performance of proposed architecture is further compared with existing NVIDIA architecture and its pruned variants (pruned by 22.2% and 33.85% using 1x1 filter to decrease the total number of parameters). Experimental results show that the VGG16 with transfer learning architecture has outperformed other discussed approaches with faster convergence.
