UnverifiedTabPFN的预训练使用由结构因果模型和贝叶斯网络等概率生成模型采样得到的合成数据集79% similarUnverifiedTabFM does not require users to train with their own datasets; instead, it takes labeled rows and unlabeled rows to be predicted as joint input and directly infers answers in a single forward pass.71% similarVerifiedAt inference time, TabPFN concatenates the entire training set as the Transformer input sequence and completes prediction in a single forward pass without any gradient updates.71% similarUnverified2023年提出的TabPFN首次实现了表格数据的in-context learning，通过将训练样本作为上下文输入在推理时完成小规模数据集分类，无需梯度更新68% similar
