Optimization Techniques in Machine Learning Models Using Banach Space Theory: Applications in Engineering and Management

This paper explores the interplay between Banach space theory and machine learning optimization, offering novel theoretical insights with applications in engineering and management. We establish a suite of original theorems that bridge functional analysis and data-driven models, including: (1) convergence rates for gradient descent in reflexive Banach spaces under norm-attainability conditions, (2) operator norm bounds governing neural network generalization, and (3) adversarial robustness guarantees via Lipschitz continuity in non-Euclidean settings. Methodologically, we develop Banach-space analogues of fundamental results-from SVM duality to PID control stability-while demonstrating their utility in resource allocation and time-series forecasting through Orlicz space embeddings. Our framework not only extends classical optimization theory to infinite dimensional function spaces but also provides implementable regularization strategies for deep learning. The results are substantiated by rigorous proofs leveraging weak∗ compactness, spectral radius analysis, and semigroup theory. For practitioners, we derive explicit error bounds and convergence rates applicable to high-dimensional datasets and non-smooth objectives. This work thus unifies abstract functional-analytic concepts with modern machine learning challenges, offering new tools for both theoretical analysis and algorithmic design.
