它采用了文本分类(Text Classification)、文本生成(Text Generation)和序列标记(Sequence Tagging)等多种任务的学习策略,具备了广泛的应用能力。 ERNIE(2020)ERNIE是一种基于Transformer结构的深度语义表示模型,由中国科学院计算技术研究所开发。它采用了结构化知识的增强策略,提高了模型对语义信息的理解和利用效率。
3.1 Single-text Classification(单句分类) 常见的单句分类任务有短文本分类、长文本分类、意图识别、情感分析、关系抽取等。给定一个文本,喂入多层Transformer模型中,获得最后一层的隐状态向量后,再输入到新添加的分类器MLP中进行分类。在Fine-tuning阶段,则通过交叉信息熵损失函数训练分类器; ...
The general pre-training corpora are large-scale datasets composed of extensive text from diverse domains and sources. Their primary characteristic is that the text content is not confined to a single domain, making them more suitable for training general foundational models.Corpora are classified base...
这里加入Task Classification子任务主要还是为了针对性的去拟合few-shot case。不同难度的类别下的prompt会有区别,并且有难度标签在生成数据可视化参数时,能为下游子任务提供额外的信息特征,便于LLM更友好的生成对应的参数K-V对信息。 SQL Generation: 这里的SQL Generation是通过上一子任务确认对应的prompt模板,根据业务...
DeepSeek R1, the latest and greatest in DeepSeek’s lineup was created by building upon the base DeepSeek v3 model. R1 is a MoE (Mixture-of-Experts) model with 671 billion parameters out of which only 37 billion are activated for each token. A token is like a small piece of text, ...
