UnverifiedData mixture ratio refers to the proportion of different types of data in a pre-training dataset, and profoundly affects the distribution of a model's capabilities.80% similarUnverifiedStock price series are typical non-stationary data, and the substantial change between the data distribution at model training time and at prediction time is referred to in statistics as 'concept drift'.74% similarUnverifiedData drift or concept drift refers to the phenomenon where model performance degrades significantly when the real-world data distribution changes while the model is still trained on old data; the industry addresses this with continuous learning and active learning strategies.72% similarUnverifiedDiffusion models have a natural tendency to generate high-frequency details and textures present in the training data distribution; if certain elements are not explicitly removed, the model will by default fill in content it considers 'should be there'.70% similarUnverifiedCurrent mainstream diffusion models tend to select the highest-probability denoising path at each step, causing generated results to gravitate toward the statistical center of the training data distribution and exhibit the most averaged visual presentation.70% similar
