Alexander Schperberg

Alexander Schperberg
  • Biography

    Alexander's background includes extensive experience in employing hybrid machine-learning and model-based approaches towards planning, control, and estimation in both simulation and hardware including legged, climbing, wheeled, and flying robots. His Ph.D work covers topics such as reinforcement learning, Active SLAM, stochastic model predictive control, force control for manipulation and grasping, and estimation using filtering methods combined with vision transformers and deep learning techniques. His current research interests focus on advancing learning methods, from traditional neural networks to large language models, through embedded
    knowledge of the underlying physics of the environment, robots, and contacts between them.
