Zero-shot学习（Zero-shot Learning） |
<p>Zero-shot是指学习在训练阶段不存在与测试阶段完全相同的类别，但是模型可以使用训练过的知识来推广到测试集中的新类别上。</p>
<p>这种能力被称为“零样本”学习，因为模型在训练时从未见过测试集中的新类别，在模型训练和提示词优化中均有体现。</p>
<p> </p>
<p style="language: zh-CN; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0in; text-align: left; direction: ltr; unicode-bidi: embed; mso-line-break-override: none; word-break: normal; punctuation-wrap: hanging;"><strong>在模型训练中：</strong></p>
<ul>
<li style="text-align: left; direction: ltr; unicode-bidi: embed; word-break: normal;">已知马（四脚兽）、虎（有条纹）、熊猫（黑白色）的特征，但未训练过斑马的数据（不认识）</li>
<li style="text-align: left; direction: ltr; unicode-bidi: embed; word-break: normal;">告知模型：斑马是四脚兽、有黑白色的条纹</li>
<li style="text-align: left; direction: ltr; unicode-bidi: embed; word-break: normal;">模型可以在已知数据中进行推理，从而识别斑马。</li>
</ul>
<p> </p>
<p><strong>在提示词优化中：</strong></p>
<ul>
<li>Zero-shot思想用于基于已训练的能力，不提供任何示例，仅通过语言去描述任务的要求、目标和约束，让模型直接生成结果。</li>
</ul>
<p>简单来说就是“用语言定义任务，解放（信任）模型的预训练知识”</p>
<p> </p>
<p>比如：</p>
<p>请判断””包围的用户评论中的情感倾向，输出 正面 或 负面。</p>
<p>”这款代餐鸡胸肉饱腹感很强，吃起来也不柴，很推荐！”</p>
<p> </p>

Few-shot学习（Few-shot Learning） |
<p>Few-shot学习是指少样本学习，当模型在学习了一定类别的大量数据后，对于新的类别，只需要少量的样本就能快速学习，对应的有one-shot learning，单样本学习，也算样本少到为一的情况下的一种few-shot learning。</p>
<p> </p>
<p><strong>在模型训练中（相似度判断方法）：</strong></p>
<ul>
<li>基于少量企鹅样本并结合相识度判断，推论未知图片内含“企鹅”</li>
</ul>
<p> </p>
<p><strong>在提示词优化中：</strong></p>
<ul>
<li>Few-shot主要用于基于少量示例，让模型参考示例回答。</li>
<li> </li>
</ul>
<p>简单来说就是“用示例定义任务，在模型的预训练知识的基础上，提升模型回答的对齐精度（比如参考示例的格式）”</p>
<p> </p>
<p>比如：</p>
<p>请抽取产品名称和核心卖点2个字段，格式为Json，我提供2个示例。</p>
<p><em>示例1：MacBookPro高效节能，性能强大，适合牛马工作使用</em></p>
<p><em>输出：{“产品名称”: “MacBookPro”, “产品卖点”: “高效节能，性能强大”}</em></p>
<p><em>示例2：联想笔记本拥有RTX4060独立显卡，畅玩游戏，丝滑流畅</em></p>
<p><em>输出：{“产品名称”: “联想笔记本”, “产品卖点”: “畅玩游戏，丝滑流畅”}</em></p>
<p>请处理：华为MatepadPro，高清大屏，长效续航，你的好帮手。</p>
<p> </p>
<p><em>{“产品名称”: “华为MatepadPro”, “产品卖点”: “高清大屏，长效续航”}<br /><br /></em></p>

RAG数据清洗三大关键点 |
<p>1、文本切分：500-100字符/chunk，设10%-20%重叠防信息割裂。</p>
<p>2、PDF解析：要做结构感知，用LayoutLM画出边缘线再提取文字或者用GPT-4V/Llama Pass把PDF转成文字再提取文字，核心就是让机器看清楚文档结构，避开基础库乱码</p>
<p>3、存储格式：坚持Markdown，主流的大模型利用了github上大量的md文件加入了训练，对此格式敏感，理解度高。对后续的检索和生成的准确性会大幅度提升</p>
<p>三者环环相扣，从文本切分的语意完整 到 PDF结构准确性 再到 数据存储的格式适配性。把这三个基础环境做扎实RAG的效果就会有很大提升</p> |
