3 End-to-End Adaptive Local Learning
To debias, we propose the end-To-end Adaptive Local Learning (TALL) framework, shown in Figure 2. To address the discrepancy modeling problem, this framework integrates a loss-driven Mixture-of-Experts module to adaptively provide customized models for different users by an end-to-end learning procedure. To address the unsynchronized learning problem, the framework involves an adaptive weight module to synchronize the learning paces of different users by adaptively adjusting weights in the objective function.
