The log-variance loss proposed in 2023 to 2024 replaces the expectation under the current model with an arbitrary reference process, allowing sample reuse and gradient truncation, but the high-variance gradients make optimization extremely unstable, and it still requires storing the full trajectory.

VerifiedGradient descent iteratively adjusts weights in the opposite direction of the loss function's gradient, causing the prediction error to converge progressively.74% similarUnverifiedWeighted conformal prediction approximates a weakened version of the exchangeability condition by assigning weights to historical samples based on temporal decay or similarity.73% similarVerifiedIn autoregressive prediction, errors at each step accumulate into the next, causing long-range predictions to degrade rapidly.73% similarUnverifiedIn adversarial MDPs, the environment can choose an arbitrary loss function at each episode (possibly depending on the algorithm's history), and the loss can vary arbitrarily over time, so standard optimistic or confidence upper bound methods no longer apply directly.72% similarVerifiedThe core challenge of MLOps lies in model drift: as real-world data distributions change over time, model prediction accuracy gradually declines.72% similar
