Abstract
The advent of deep learning has revolutionized predictive modeling across unstructured data domains, largely driven by the capacity of deep neural networks to learn hierarchical, high-dimensional feature representations. Among the most critical architectural innovations of the past decade, Residual Networks (ResNets) have been instrumental in enabling the training of ultra-deep models by mitigating the vanishing gradient problem through identity shortcut connections. Concurrently, ensemble learning methods—particularly Gradient Boosting Machines (GBMs)—have dominated tabular data tasks by iteratively combining weak learners to minimize an arbitrary differentiable loss function. This paper investigates the profound theoretical and empirical intersections between these two seemingly disparate paradigms. We posit and mathematically demonstrate that Residual Networks can be conceptually interpreted as implicit boosting models. By unrolling the recursive structural equations of ResNets, we illustrate that individual residual blocks function analogously to additive weak learners in a boosting ensemble, where each subsequent layer is jointly optimized to fit the residual error of the preceding layers' representations. This research formalizes the fundamental equivalence between additive modeling in gradient boosting and the residual mapping in deep neural networks. Furthermore, we explore the empirical implications of this equivalence, conducting theoretical analyses of lesion studies, stochastic depth optimization, and gradient flow stability. Our findings provide a unified framework that enhances the interpretability of deep representation learning, demystifies the robustness of skip-connections, and paves the way for novel hybrid architectures that leverage the strengths of both global backpropagation and ensemble robustness.
