New framework unifies Lyapunov-IQC for accelerated optimizer stability

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework using Lyapunov functions and integral quadratic constraints (IQC) to analyze the uniform stability of accelerated first-order optimization algorithms. This approach extends previous work on stochastic gradient descent (SGD) to methods like Nesterov Accelerated Gradient (NAG), which are more complex due to momentum dynamics. The framework models optimizers as feedback interconnections and uses linear matrix inequalities (LMIs) solvable via semi-definite programming (SDP) to certify stability, offering a modular method for verifying optimization algorithms.
