1、Source Documents → Text Chunks:A fundamental design decision is the granularity with which input texts extracted from source documents should be split into text chunks for processing. In the following step, each of these chunks will be passed to a set of LLM prompts designed to extract the...

Although retrieval-augmented generation offers several advantages in LLM use cases, there are still significant challenges when implementing RAG. Here, we explore prominent challenges related to implementing RAG practices. a. Potential biases in retrieval-based models One of the significant challenges in ...
在知识库问答等场景中,RAG已经成为当下最流行的LLM应用范式,为LLM提供又全又准的上下文信息是众多RAG技术努力的方向。在传统的 RAG 解决方案中,编码信息时往往会丢失上下文,这导致系统无法从知识库中检索到相关信息,如何能够更好地保留上下文信息成为了问题关键。
The system retrieves the most relevant contexts based on how closely their vectors match the query vector. Retrieved Contexts: The contexts that have been retrieved are then passed along to the Large Language Model (LLM). These contexts contain the information that the LLM uses to generate a ...

Atlas主要针对LLM引入retriever,通过联合预训练retriever和LLM,在广泛的知识密集型任务上具有强大的few-shot学习能力。 模型基于两个子模型:retriever和LM。首先使用retriever从大型文本语料库中检索最相关的文档。然后,这些文档与query(query置于文档前)一起送入到语言模型,生成输出。 联合训练优化retriever以及对应retriever...

1 简介:Retrieval-based LMs = Retrieval + LMs 首先对于一个常规的(自回归)语言模型,其任务目标为通过计算P(xn|x1,x2,...,xn−1)并加以采样来预测句子中的下一个token,以此来完成对于整个句子的生成。 掩码语言模型/编码器-解码器语言模型的概率计算方式与此不同,但在此不做过多讨论。 而检索增强的语言...
