UnverifiedSelf-supervised TTT work can be traced back to around 2020, enabling models to adapt to the current input by constructing auxiliary self-supervised tasks (such as rotation prediction) on test samples.68% similarUnverifiedUnder the frozen-encoder linear probing setting, TS2Vec-FM surpasses TS2Vec trained separately on each target dataset.67% similarUnverified测试时训练（TTT）在推理阶段利用当前输入的自监督信号对部分参数进行短暂局部梯度更新再执行预测65% similarUnverifiedThresholds must be validated on a holdout set fully independent of the training data and calibrated to the expected deployment distribution.64% similarVerified时间序列预测的正确做法是采用前向链式验证，训练集只能包含验证时间点之前的数据64% similar
