Abstract

The accelerating integration of deep learning models into safety-critical, economic, and societal decision-making systems has foregrounded the urgent challenge of adversarial robustness. While early adversarial machine learning research was predominantly anchored in computer vision, recent advances demonstrate that time series models—widely deployed in finance, healthcare, cybersecurity, climate forecasting, and industrial monitoring—are equally vulnerable to carefully crafted perturbations. This article presents a comprehensive, theory-driven, and empirically grounded examination of adversarial attacks and defenses across both computer vision and time series learning paradigms, with a particular emphasis on neural architectures, evaluation protocols, and ensemble-based strategies. Drawing upon an extensive and diversified body of literature, the study synthesizes foundational adversarial concepts, modern attack mechanisms, and contemporary defense methodologies, including adversarial training, distillation, ensemble learning, and robustness-oriented architectural design. The analysis is guided by the recognition that adversarial vulnerability is not an incidental artifact of specific models, but rather an emergent property of high-dimensional statistical learning systems optimized under conventional empirical risk minimization. By integrating insights from seminal theoretical works and recent empirical contributions, including comprehensive surveys and domain-specific studies, this article articulates a unified conceptual framework that bridges computer vision and time series classification. The methodological section outlines a rigorous literature-driven analytical approach that emphasizes interpretive synthesis over numerical benchmarking, enabling cross-domain comparison without reliance on visual or mathematical formalism. The results section presents an in-depth descriptive analysis of adversarial behaviors, highlighting recurring patterns of susceptibility, transferability, and defense trade-offs observed across domains. The discussion extends these findings into a broader scholarly debate, interrogating assumptions about robustness, the limits of current defenses, and the epistemic implications of adversarial machine learning for trustworthy artificial intelligence. The article concludes by identifying critical research gaps and proposing theoretically informed directions for future work, particularly in the development of domain-aware defenses and evaluation frameworks that move beyond narrow threat models.
