Explore new functionality in StructuralIdentifiability.jl for model reparametrization in this 11-minute conference talk from JuliaCon 2024. Learn how to quickly identify rational functions of parameters and states that are identifiable in a given model, potentially leading to reparametrization. Discover the package's unique capabilities through simple yet meaningful examples and a brief demonstration. Gain insights into this crucial step of model design, applicable to practitioners in modeling and control. The presentation focuses on practical applications rather than technical details, with further information available in the package documentation.
