Outline
Autonomous driving platforms face diverse driving environments, varying hardware resource and precision requirements, and computational constraints on embedded devices require consideration of computing costs. This study aims to tailor a semantic segmentation network to the computing power and specific scenarios of target platforms such as NVIDIA DRIVE PX 2. Dynamic adaptability is achieved through a three-layer control mechanism—width multiplier, classifier depth, and classifier kernel—to fine-tune model components based on hardware constraints and task requirements. Furthermore, Bayesian optimization is utilized to efficiently explore the hyperparameter space within a limited computational budget, and multiply-accumulate operations (MACs) for task-specific learning adaptation (TSLA) are coordinated to generate alternative configurations for various autonomous driving tasks.
