[ICTM] 2026-04-07 (13:00) : Dealing with Variability and Mismatch in Closed‑Loop Neuromorphic Control: From Limitations to Design Opportunities
At Shannon room
Speaker:
Alessio Franci (Liège)
Abstract: Neural systems exhibit substantial variability in their underlying parameters, yet they reliably generate robust and adaptive closed-loop behaviors in sensorimotor tasks. Neuromorphic systems display an analogous form of variability, primarily due to transistor mismatch, raising the question of how such mismatch can be exploited rather than suppressed. Understanding how to harness this inherent device-level variability to design robust and adaptive neuromorphic controllers is an active and promising research direction.
In this talk, I will first introduce the mechanisms and functional roles of variability in biological neural systems and relate them to parameter mismatch in neuromorphic hardware, with a particular focus on closed-loop control scenarios. Building on this background, I will present two recent lines of work: (i) variability in human gait control, and (ii) a quantitative analysis of mismatch effects in fully analog neuromorphic neurons. I will conclude with an overview of emerging neuro-inspired strategies leveraging transistor mismatch to achieve robustness and adaptability in neuromorphic control systems.
[ICTM] 2026-02-24 (13:00) : Distributed, Coordination-Free Programming: 10 Years of Progress Since Lasp
At Shannon Room, Maxwell Building, 3 Place du Levant, Louvain-la-Neuve
Speaker:
Peter VAN ROY (UCL)
Abstract: Consensus is a critical building block for building fault-tolerant distributed systems. It is widely believed that without consensus, large distributed applications on the Internet could not exist. But recent advances show that consistent replication can be achieved without consensus by using convergent data structures such as CRDTs (conflict-free replicated data types). This is called coordination-free programming and it has become a credible alternative to consensus. The Lasp system is the first to compose CRDTs. It was published in 2015 in the ACM Symposium on Principles and Practice of Declarative Programming (PPDP) and the paper won the 10-year most influential paper award at PPDP 2025. Lasp’s coordination-free model has inspired a decade of progress in academia and industry. As the industry shifts toward multi-region deployments, Lasp’s core insight — that coordination can be the exception, not the rule — continues to shape how we build reliable, scalable systems today.
