UnverifiedThe time series field has long lacked unified large-scale pretraining corpora, causing models to often be trained for a single dataset or a single domain.75% similarUnverifiedHigh-quality training data available on the public internet is being rapidly consumed by large models and is becoming scarce.74% similarUnverifiedMinority-class-prioritized data collection brings some benefit when the training set is very small, but its advantage does not persist as the amount of data increases.74% similarUnverifiedWhen the distribution of online data deviates from the training data, model performance degrades (data drift and model decay), requiring retraining to be triggered.73% similarUnverifiedIn real-world scenarios, the source training set and the target test set are rarely identically distributed.73% similar
