Talk Title: From Dexterous Assembly to AMR Fleet Planning: Robotics Research at Bosch
Abstract: The Bosch Group has a uniquely diverse set of robotic products and applications, from consumer, to professional service, to industrial robotics. The research topics in robotics being studied at the various Bosch Research locations around the globe are even broader. In the first part, this talk gives an overview to these topics including SLAM, human motion prediction, and MPC based motion planning for mobile robots, learning and planning for complex assembly tasks with dexterous joining processes, scene segmentation and learning for robot handling in warehouses, novel mechatronic elements for robotic insertion processes in mass production.
The second part covers research on robot software platforms and tools, with many contributions to the open source Robot Operating System. This includes for example micro ROS, execution management, and very new research on methods for model checking of robot deliberation with Behavior Trees. Finally, in the third part, a spotlight on the research on multi agent path finding for AMRs in intralogistics but also for contactless planar systems such as ctrlX FLOW6D is given.

Biography: Ralph Lange is head of the global research portfolio for robotics at Bosch. Since 2018, he has been Principal Investigator in three EU funded projects. OFERA (micro ROS), MROS, and CONVINCE. In the last years and in his role as Chief Expert for Robotic Systems and Software Engineering, he has been particularly active in the ROS community and represented Bosch in the ROS 2 Technical Steering Committee and ROS Industrial Europe. Before joining Bosch in 2013, Ralph worked as a software engineer for TRUMPF Machine Tools. He obtained his PhD in computer science from the University of Stuttgart, Germany in 2010.

Title: Robust and Context Faithful Language Understanding with (Large) Language Models
Abstract: Large language models (LLMs) have achieved remarkable success in various language understanding tasks. However, their deployment in real world scenarios raises significant accountability concerns. In this talk, I will begin with the contextual faithfulness issue. LLMs often rely on biased parametric knowledge to make unfaithful predictions. I will present a causality driven approach aimed at mitigating entity bias to ensure context faithful NLU. Subsequently, I will introduce the robustness issue against unknown prediction shortcuts. I will demonstrate how to address the issue by proactively mitigating attention biases. Finally, I will outline potential future directions for advancing LLM accountabilityAudiences: Everyone Is Invited

CS Colloquium: Michael Safaee (Keck) - From Tethers to Telomeres: Advances in Spine Surgery

Talk Title: From Tethers to Telomeres: Advances in Spine Surgery
Abstract: Junctional mechanical failures are a well recognized complication of long segment spinal fusions. Ligament augmentation with tethers can reduce junctional stress and minimize rates of proximal junctional failure PJF. A total of 242 patients with tethers were analyzed and compared to a historical cohort of 77 patients without tethers. Rates of reoperation for PJF were significantly lower with tethers 3.3 percent vs. 15.6 percent, p less than 0.001. A propensity matched cohort of 40 patients in each arm found similarly lower rates of PJF. 2.5 percent vs 22.5 percent, p equals 0.007). PJF emphasizes the need for improved preoperative risk stratification. Telomeres are DNA protein complexes that serve an important role in protecting genomic DNA. Their shortening is a consequence of aging and environmental exposures, with well established associations with diseases of aging and mortality. Whole blood was collected preoperatively on adults undergoing spine surgery. Telomere length analysis was performed using qPCR, T over S ratio. Among 43 patients, we found no significant difference in chronological age, DMI, frailty, or preoperative disability scores when comparing patients with a postoperative complication compared to those without a complication. However, patients with complications had significantly shorter telomere length T over S 0.712 vs. 0.813, p equals 0.008, which correlated to an additional attrition of 9 to 10 years despite only 5 year difference in chronological age. These data suggest that biological age may provide valuable information on preoperative risk and improve current risk calculators.

Biography: Michael Safaee, MD, is a neurosurgeon specializing in the treatment of spinal disorders. He is trained in both traditional open and minimally invasive techniques, spinal oncology and adult deformity. While committed to caring for all patients, he has a special interest in scoliosis, kyphosis and revision surgery. Dr. Safaees goal is to treat patients with the same care he would want for his own family, providing safe, effective and durable outcomes tailored to the individual patient. Although surgery is almost always a last resort, he strives to educate patients with the knowledge needed to make the best decision for themselves. Dr. Safaee earned his medical degree from the David Geffen School of Medicine at the University of California, Los Angeles, followed by residency in the Department of Neurological Surgery at the University of California, San Francisco. He completed a fellowship in the Department of Orthopedic Surgery at The Johns Hopkins Hospital. Dr. Safaee has over 100 peer reviewed publications and his work was recognized with the Russell A. Hibbs Award by the Scoliosis Research Society. Dr. Safaees research is currently focused on surgical outcomes in adult deformity surgery and spinal oncology, with a particular interest in risk assessment and data analytics. He is exploring the use of genetic and biological age as components of risk stratification.
