The Deployment Gap: Bridging the Divide Between Deep Learning Theory and Real-World Production Even the most accurate deep learning models often fail outside the lab. The real challenge is not building AI — it's successfully deploying it in real-world environments.

Abstract

Deep learning models often reach cutting-edge accuracy in well-controlled testing environments but often fail to integrate effectively into real-world applications. This paper discusses the "deployment gap," which is an important challenge in the machine learning lifecycle. The gap occurs primarily by hardware limitations on edge devices, knowing that data drift is unavoidable in dynamic environments, and the lack of robust MLOps pipelines. This study shows a simpler way to deploy models by observing the common problems that occur when shifting models from the lab to live platforms. We evaluate useful methods like model quantization, pruning, and adding continuous monitoring systems maintain model performance after deployment. The results show that an engineering-first approach with an emphasis on latency, memory efficiency, and automated retraining is essential for deep learning applications to work well, especially in tech ecosystems.
