چکیده

In this letter, we propose a model parameter identification method via hyperparameter optimization scheme (MI-HPO). Our adopts an efficient exploreexploit strategy to identify the parameters of dynamic models in data-driven manner. We utilize our for AV-21, full-scaled autonomous race vehicle. then incorporate optimized design modelbased planning and control systems platform. experiments, MI-HPO exhibits more than 13 times faster convergence traditional methods. Furthermore, parametric learned MIHPO demonstrate good fitness given datasets show generalization ability unseen scenarios. further conduct extensive field tests validate model-based system, demonstrating stable obstacle avoidance high-speed driving up 217km/h at Indianapolis Motor Speedway Las Vegas Speedway. The source code work videos are available https://github.com/hynkis/MI-HPO.

A State and Parameter Identification Scheme for Linearly Parameterized Systems

Abstract This paper presents an adaptive algorithm to estimate states and unknown parameters simultaneously for nonlinear time invariant systems which depend affinely on the unknown parameters. The system output signals are filtered and re-parameterized into a regression form from which the least squares error scheme is applied to identify the unknown parameters. The states are then estimated b...

Hyperparameter Search Space Pruning - A New Component for Sequential Model-Based Hyperparameter Optimization

The optimization of hyperparameters is often done manually or exhaustively but recent work has shown that automatic methods can optimize hyperparameters faster and even achieve better nal performance. Sequential model-based optimization (SMBO) is the current state of the art framework for automatic hyperparameter optimization. Currently, it consists of three components: a surrogate model, an ac...
