两步预训练阶段将最终生成一个模型,该模型可作为随后对标记数据进行微调阶段的初始化,以提高分割的准确性。 2.2 Supervised Local Contrastive learning 设f l(xi) = h2(Dl(E(ai))是增强输入ai的第l个最上层解码器块Dl的输出特征映射,其中head h2是一个两层逐点卷积。对于feature map f (ai),局部对比损耗定...
semi-supervised contrastive learning训练 Semi-supervised contrastive learning is a training approach used in machine learning to leverage labeled and unlabeled data in a semi-supervised setting. In contrastive learning, the goal is to learn representations (embeddings) of data points such that similar ...

including the limited label informa-tion in the pre-training phase, it is possible to boost the performance ofcontrastive learning. We propose a supervised local contrastive loss thatleverages limited pixel-wise annotation to force pixels with the same la-bel to gather around in the embedding ...
5. 半监督序列学习(Semi-supervised Sequence Learning) 在自然语言处理(NLP)领域,半监督序列学习方法,如BERT和其它变体,通过预训练模型在大量未标注文本上学习语言表示,然后在少量标注数据上进行微调,用于特定的下游任务,如情感分析或问答系统。 在处理文本或语音数据时,半监督序列学习方法就像是掌握了一本包含秘密调味...
