01/2023: One paper accepted to ICRA

January 30, 2024

The paper collaborated with Haotian (graduate students at Tsinghua University) Synthesize Efficient Safety Certificates for Learning-Based Safe Control using Magnitude Regularization is accepted to ICRA 2024. Congratulations, Haotian!

The paper invetigates an interesting question, how to guarantee safety while being efficient. This is a very important problem. If we choose of be inefficient or conservative, the safety is very easy. For example, the autonomous vehicle...

06/2023: Two new papers got accepted recently

June 21, 2023

Two papers got accepted recently. Congratulations to all co-authors!

One paper is about multi-agent Bayesian optimization accepted to IROS 2023. In the multi-agent Bayesian optimization, a challenging question is that how to let the agents collaborate well on learning about the unknown objective function. We solve the batch queries by maximizing the joint information gain about the function maximum.  We also conduct experiements with source seeking experiments using the TurtleBot3. Check out our...

03/2023: New preprint about multi-agent Bayesian optimization

March 27, 2023

Check our new preprint paper about multi-agent Bayesian optimization! Here is the link

Multi-agent Bayesian optimization is an efficient approach for optimizing black-box functions which are difficult to evaluate. We use multiple agents to collaborate to find the optimum by maximizing the joint information gain. We conduct experiments on robotic experiments.
