End-to-End Learning - Page 3

End-to-end learning trains a system on the complete path from input to desired output instead of dividing the task into separately engineered stages. A speech model, for example, might learn to convert audio directly into text rather than relying on hand-designed acoustic features and multiple independent modules. Joint optimization can discover useful representations and reduce pipeline complexity, especially when abundant paired data is available. The tradeoff is reduced visibility into intermediate decisions, higher data requirements, and greater difficulty diagnosing failures. Hybrid designs often retain explicit components where rules, interpretability, safety checks, or limited training data make a fully end-to-end approach impractical.
