RAG技术通过结合信息检索与文本生成两大模块，有效解决了传统大语言模型的知识更新滞后和"幻觉"问题。其核心工作流程分为三个阶段： 检索阶段：根据用户查询从知识库中检索相关文档片段 增强阶段：将检索结果与原始查询结合形成增强上下文 生成阶段：基于增强上下文生成最终响应 2 Java在RAG系统中的定位 Java在RAG系统中主要承担以下关键角色： 构建高效检索后端 处理大规模文档预处理

2.6B 是一款高性能的多模态音频语言模型，参数量为 2.6B，能够高效处理文本和音频输入。它将 Gemma - 2 - 2B、WhisperTurbo 以及定制的 Projector 模块集成到一个统一框架中，突破了传统模型串联 ASR（自动语音识别）和 LLM（大语言模型）的架构限制，实现了更低延迟、更高效能的音频 - 文本一体化处理。这种一体化的设计使得音频信息能够直接在模型内部进行处理和转换，避免了传统架构中多次数据传输和处理带来的延迟和资源浪费。 <o:p></o:p> <section style="text-align: center;" nodeleaf=""> <img src="/upload/8e34ef27cc8079f530591e7a0b102634.png" class="rich_pages wxw-img" data-ratio="0.4958490566037736" data-s="300,640" data-type="png" data-w="1325" type="block" data-imgfileid="100003172"> </section> <o:p>   </o:p> <h1 style="margin-bottom: 8px;letter-spacing: 0.578px;">二、技术原理 <o:p></o:p></h1> <h2 style="margin-bottom: 8px;letter-spacing: 0.578px;">1、模型架构 <o:p></o:p></h2> Gemma - 2 - 2B：作为负责文本处理的基础语言模型，它拥有强大的语言理解和生成能力。其内部的神经网络结构经过精心设计和训练，能够对音频文本转换后的文本进行深入分析和理解。例如，在处理复杂的语义关系时，Gemma - 2 - 2B 可以准确地识别出词汇之间的逻辑联系，从而为后续的语言生成提供准确的基础。 <o:p></o:p> <ul style="list-style-type: disc;" class="list-paddingleft-1"> <li>WhisperTurbo：是优化后的音频编码器，能够生成高质量的音频嵌入。它通过对音频信号进行特征提取和编码，将音频信息转化为模型可处理的形式。WhisperTurbo 在处理音频信号时，能够捕捉到音频中的细微特征，如语音的语调、语速变化等，这些特征对于准确理解音频内容至关重要。 <o:p></o:p></li> <li>定制Projector模块：将 Whisper 的音频 token 转化为与 Gemma 文本嵌入对齐的序列，确保音频 - 文本模态的高效融合。它通过一种特殊的映射机制，使得音频和文本在向量空间中能够准确对应，同时保持语言模型的原始性能。这种对齐方式使得模型在处理音频输入时，能够像处理文本输入一样高效地进行语言理解和生成。 <o:p></o:p></li> </ul> <h2 style="margin-bottom: 8px;letter-spacing: 0.578px;">2、训练方法 <o:p></o:p></h2> <ul style="list-style-type: disc;" class="list-paddingleft-1"> <li>预训练阶段：基于 MLSEnglish10K 转录数据集进行基础的音频 - 文本对齐能力训练。为了支持多任务应用，数据集中引入了特殊的 <|trans**cribe|>token，用以区分语音转文本和内容补全任务，确保模型在不同场景下性能的一致性。在预训练过程中，模型通过大量的音频 - 文本对数据学习，逐渐掌握音频和文本之间的对应关系，形成初步的音频处理和语言理解能力。 <o:p></o:p></li> <li>监督微调阶段（SFT）：使用合成数据集进行指令调优。数据集同样以 MLSEnglish10K 为基础，结合专有模型对上下文进行扩展，生成丰富的 “音频 - 文本” 对。通过这种方式，模型具备了更强的音频输入语义理解和会话生成能力。例如，在处理特定领域的音频数据时，模型能够根据微调数据中的领域知识，准确理解音频中的专业术语和特定表达方式。 <o:p></o:p></li> <li>直接偏好优化（DPO）：利用 GPT - 4O API 对模型初始输出进行评估，标注不正确的输出为 “拒绝”（rejected），并生成替代答案作为 “偏好”（preferred）参考。为了保持 Gemma - 2 的文本处理性能，额外增加了偏好训练步骤，使用 Gemma - 2 的原始文本作为 “标准” 训练模型，在处理音频输入时匹配其高水平表现。通过 DPO，模型能够不断优化自己的输出，使其更加符合人类的语言习惯和实际需求。 <o:p></o:p></li> </ul> <h1 style="margin-bottom: 8px;letter-spacing: 0.578px;margin-top: 24px;" data-mpa-action-id="m6lp72m21nfv">三、功能特点 <o:p></o:p></h1> <h2 style="margin-bottom: 8px;letter-spacing: 0.578px;">1、处理速度快 <o:p></o:p></h2> 在 2024 Mac Mini M4 Pro 上，使用 Nexa SDK 并采用 FP16 GGUF 格式时，模型可实现每秒 35.23 个令牌的处理速度，而在 Q4_K_M GGUF 格式下，可处理每秒 66 个令牌。相比之下，Qwen2 - Audio - 7B 在相似硬件上只能处理每秒 6.38 个令牌，展示出显著的速度优势，能够满足实时音频处理的需求。例如，在实时语音翻译场景中，快速的处理速度可以确保翻译结果几乎与语音同步输出，大大提高了沟通效率。 <o:p></o:p> <h2 style="margin-bottom: 8px;letter-spacing: 0.578px;">2、资源效率高</h2> 模型的紧凑设计有效减少了对云资源的依赖，使其成为功率和带宽受限的可穿戴设备、汽车系统及物联网设备的理想选择，降低了设备的运行成本和对网络的依赖。在一些网络信号不稳定的偏远地区，或者在电池续航有限的可穿戴设备上，OmniAudio - 2.6B 能够凭借其低资源消耗的特点，稳定地运行并提供准确的音频处理服务。 <o:p></o:p> <h2 style="margin-bottom: 8px;letter-spacing: 0.578px;">3、高准确性和灵活性 <o:p></o:p></h2> 尽管 OmniAudio - 2.6B 专注于速度和效率，但其在准确性方面也表现不俗，适用于转录、翻译、摘要等多种任务。无论是实时语音处理还是复杂的语言任务，OmniAudio - 2.6B 都能够提供精准的结果。例如，在处理学术讲座的音频转录时，模型能够准确识别专业术语和复杂的句子结构，生成高质量的文字转录稿。 <o:p></o:p> <h1 style="margin-bottom: 8px;letter-spacing: 0.578px;margin-top: 24px;" data-mpa-action-id="m6lp82e2ife">四、应用场景 <o:p></o:p></h1> <h2 style="margin-bottom: 8px;letter-spacing: 0.578px;">1、智能家居 <o:p></o:p></h2> 可以集成到智能家居设备中，如智能音箱、智能家电等，实现语音控制和交互。用户可以通过语音指令控制家电的开关、调节温度、查询信息等，提供更加便捷的智能家居体验。例如，用户只需说出 “打开客厅的灯”，智能音箱中的 OmniAudio -

压缩算法是用于减小文件大小的数学方法。它通过各种技术，如替换、重新编码、差分编码、运行长度编码、字典编码、变换编码等，来减少数据的冗余和实现数据的体积缩小。压缩算法可以是无损的或有损的： <section style="margin-top: 10px;margin-bottom: 10px;text-align: center;"> <section style="display: inline-block;width: 100%;border-width: 1px;border-style: solid;border-color: rgb(160, 160, 160);padding: 10px;"> <section style="text-align: justify;line-height: 1.8;padding-right: 5px;padding-left:

</section> 4.2.2 解压算法 <section> 解压算法是压缩算法的逆过程，它用于将压缩文件恢复到其原始状态。无损压缩的解压算法能够完全恢复原始数据，而有损压缩的解压算法则可能无法完全恢复所有原始数据。 文件压缩和解压缩简单流程图如下： </section> <img class="rich_pages wxw-img js_insertlocalimg"

flex-start;"> <section style="text-align: justify;width: 100%;"> 注意：数据的压缩算法和解压算法要一样 </section> </section> 4.2.3 压缩块 <section> 文件压缩块是指对文件进行压缩处理后生成的一组连续的数据块。在文件压缩过程中，文件被分割成多个块，每个块都经过压缩算法处理。一般来说，文件压缩块的大小可配置。例如，ZIP压缩的每个压缩块的大小可以达到64KB或更大，而在其他压缩格式如7z中，压缩块的大小可以更大，通常为数MB。这些大小可以根据文件的特性和压缩算法的性能进行调整，以达到更好的压缩比和解压性能。 </section> <section style="margin: 10px 0% 8px;text-align: left;justify-content: flex-start;display: flex;flex-flow: row;width: 100%;border-left: 3px solid rgb(65, 95, 255);border-bottom-left-radius: 0px;padding-left: 8px;align-self: flex-start;"> <section style="text-align: justify;width: 100%;"> 注意：在解压文件的过程中会从文件中读取整个压缩块数据到内存之后再使用解压算法进行解压处理，所以压缩块越大每次解压读取到内存里的数据会越大。 </section> </section> 4.3 加密压缩文件读写大致流程 在掌握了数据加密和压缩的基础知识之后，让我们从宏观的角度了解一下ORC加密文件读写流程，如下图所示：在写入时，内存中的数据首先被序列化，然后压缩以减少体积，最后对数据加密。在读取时，数据首先被解密以恢复原始格式，然后解压数据得到原始数据，最后通过反序列化原始数据转换为内存对象。 <img class="rich_pages wxw-img js_insertlocalimg"

<section> statKey：用于解密加密列的FileStat，StripeStat的密钥，每个列一个，加密存储在文件Footer里。 dataKey：用于解密加密列的IndexData 和 RowData，每个Stripe的每一列都有一个，加密存储在Stripe的Footer里。 masterKey：文件的根密钥，用于解密ORC文件中被加密的statKey 和 dataKey，该密钥没有存储在文件中，一般存储在Hive表属性上。要解密ORC文件中的数据，首先需要获取这个masterKey。然而，masterKey本身也是加密的，因此在读取Hive表之前，必须先从表属性中提取出加密的masterKey,访问密钥管理服务（Key Management Service, KMS），对加密的masterKey进行解密，从而获得可用于实际解密操作的明文masterKey密钥，一旦获得了masterKey的明文形式，就可以用它来解密ORC文件中的dataKey和statKey。 <img class="rich_pages wxw-img js_insertlocalimg" data-imgfileid="100016557" data-ratio="0.43703703703703706" data-s="300,640" src="/upload/39c21dd10bbf195f1ead8a2ab82ec2ec.png" data-type="png" data-w="1080" style=""> 下图是描述了masterKey、statKey，dataKey之间的关系，灰色部分代表是存储在文件中被加密的数据，绿色部分则是解密之后的数据，包括我们解密后的statKey，dataKey。获得这两个密钥之后分别用于解密统计信息和文件中的真实数据。 </section> 5.2 StarRocks读取ORC加密文件流程 在深入掌握了ORC文件中密钥的相互关系和功能后，我们现在转向探讨StarRocks是如何读取ORC加密表的数据。这个过程如下图所示： <img class="rich_pages wxw-img js_insertlocalimg" data-imgfileid="100016558" data-ratio="0.6620370370370371" data-s="300,640" src="/upload/2da52c31978ab8fece7505bd17e573ea.png" data-type="png" data-w="1080" style=""> <section> 1）提交SQL查询：用户首先通过SQL客户端向StarRocks FE节点提交查询请求。这通常涉及到对Hive表下存储的ORC加密文件进行读取操作。 2）获取解密的masterKey：查询提交后，系统首要根据SQL获取Hive表中的ORC文件所需的masterKey。这个masterKey一般存储在表属性里，并且是加密存储的，必须调用KMS服务来解密，得到密钥明文。 3）传递masterKey明文：解密后的masterKey，以明文形式传递给StarRocks BE节点。 4）读取并解密密钥：BE 拿到已解密的masterKey 之后读取并解密ORC文件中的statKey和dataKey，这两个密钥分别用于解密统计信息（FileStat，StripeStat）和实际数据内容，为接下来的统计信息和数据解密做准备。 5）使用statKey和dataKey解密数据：BE使用statKey来解密文件的统计信息（fileStat和StripeStat）同时使用dataKey来解密实际的数据内容。 </section> 5.3 读取ORC加密文件的关键实现细节 <section> 通过了解前文StarRocks读取ORC加密文件流程，我们将深入探讨读取ORC加密文件的数据关键实现细节。首先，我们提出一个问题：在物理存储中，文件存储的是什么内容？答案是二进制数据。这些二进制数据通常会经过压缩处理。 ORC文件的读取流程是自外向内的，类似于剥洋葱的过程，逐步深入到我们需要读取的目标数据。读取流程可以概括为：首先读取文件元数据，通过元数据获取目标数据的偏移量（offset）和数据长度如下图所示，然后通过流的方式读取目标数据。 <img class="rich_pages wxw-img js_insertlocalimg" data-imgfileid="100016559" data-ratio="0.3074074074074074" data-s="300,640" src="/upload/14288426e0757811d4f1429d2f3d7a92.png" data-type="png" data-w="1080" style=""> </section> 具体到ORC加密文件的读取实现代码，主要采用了设计模式中的装饰模式方式来组织代码的。在这个模式中，原始的文件流（SeekableFileInputStream）首先被解密流（DecryptionInputStream）所包装，如果是非加密文件就没有这一层，然后解密流又被解压缩流（DecompressionStream）所包装。每一层流都只负责向其包装的流请求数据，并在接收到一定量数据后开始处理自己的逻辑。如下图所示： <img class="rich_pages wxw-img js_insertlocalimg" data-imgfileid="100016560" data-ratio="0.4648148148148148" data-s="300,640" src="/upload/f9fd706e9d7a1998f761bd2c3d8dee24.png" data-type="png" data-w="1080" style=""> 这种分层的方法保证每一层都专注于自己的职责，共同协作完成ORC文件的读取任务。通过这种方式，我们不仅能够高效地读取ORC文件，还能确保数据的安全性和完整性。综上所述，ORC文件的读取流程是一个从文件元数据到具体数据内容的逐步深入过程。 5.4 加密字段跳读机制 为了提升数据的查询效率，查询数据时会根据索引数据跳过不必要的数据读取，下面我们介绍加密列跳读机制，理解了这部分的内容，就能非常清晰的知道，读取加密字段时，对数据解密与解压是怎样协作的。 5.4.1 加密块与压缩块的关系 加密列的数据划分了多个加密块与压缩块，一个压缩块包含多个加密块，读取数据时，先对每个加密块进行解密，解密多个加密块之后，把这些解密后的数据块合并成一个完整的压缩块，然后对这个压缩块进行解压得到原始数据下图是加密块与压缩块的关系图： <img class="rich_pages wxw-img js_insertlocalimg" data-imgfileid="100016561" data-ratio="0.31851851851851853" data-s="300,640" src="/upload/079b939f13b3b436e41b2fea58b824f0.png" data-type="png" data-w="1080" style=""> 5.4.2 ORC文件使用的加解密算法和模式 下图描述了具体的数据加解密过程中以及设计到整个过程中各种元素输入输出的关系： <img class="rich_pages wxw-img js_insertlocalimg" data-imgfileid="100016562" data-ratio="0.4046296296296296" data-s="300,640" src="/upload/128173fc3a3aa63e5f8178c07a05df25.png" data-type="png" data-w="1080" style=""> <section style="margin: 10px 0% 8px;text-align: left;justify-content: flex-start;display: flex;flex-flow: row;width: 100%;border-left: 3px solid rgb(65, 95, 255);border-bottom-left-radius: 0px;padding-left: 8px;align-self: flex-start;"> <section style="text-align: justify;width: 100%;"> 注意：同一个数据块（16字节）加密过程和解密过程中的密钥、IV值、加密算法和加密模式必须相同。 </section> </section> <section> 明文块：我们对ORC文件加密使用的加密算法是AES-128-CTR/NoPadding，该算法加密数据时，会把明文按照16个字节划分多个块，每个块加密之后得到的数据就是加密块。 加密块：每个明文数据块加密之后得到的数据就是加密块。 初始向量IV：初始向量IV的作用是使加密更加安全可靠（加盐），我们使用AES加密时需要主动提供这个初始向量IV，而且只需要提供一个初始向量就够了，后面每个数据块的加密向量由加密模式决定，所以每个数据块的加密向量都不一样。初始向量IV的长度规定为128位16个字节，ORC文件解密参数 IV的描述如下：总共16个字节，前面8个字节分别存储：列ID，Stream类型，Stripe的ID ，后面8个字节用于填充min_count，由于我们使用的是CTR加密模式，所以这个min_count就是加密块在整个加密数据中的计数，iv各个内容长度定义如下图： <img class="rich_pages wxw-img js_insertlocalimg" data-imgfileid="100016563" data-ratio="0.2972972972972973" data-s="300,640" src="/upload/bed7e4bfa84f0df035075e3931c46522.png" data-type="png" data-w="1036" style=""> 密钥：AES要求密钥的长度可以是128位16个字节、192位或者256位，位数越高，加密强度自然越大，但是加密的效率自然会低一些，因此要做好权衡。我们开发通常采用128位16个字节的密钥，我们使用AES加密时需要主动提供密钥，而且只需要提供一个密钥就够了，每个数据块加解密使用的都是同一个密钥。 加密模式：有5种加密模式，这些加密模式的主要目的是为了不让重复的明文加密之后得到的密文一样，提升数据安全性，我们使用的是CTR模式（计数器模式）对数据加密，那解密的时候也需要CTR模式对数据解密，计数器模式介绍请参考链接，CTR模式的iv参数包含了加密块计数（min_count），所以每次对一个加密块解密时需要知道当前加密块的初始计数值。 </section> 5.4.3 举例说明跳读流程 学习了前面读取加密数据的关键细节之后，举个例子说明跳读ORC文件流程，假设根据索引数据和查询条件确定需要读取某个文件中第1个Strip中第1列的第5个group的数据，那么我们知道group5数据的偏移量offset，文件结构如下图所示： <img class="rich_pages wxw-img js_insertlocalimg" data-imgfileid="100016564"

group5数据在哪个压缩块里,计算公式为：block_index = group_offset/zipBlockSize（压缩块大小），并得到该压缩块的起始位置zip_head_offset 公式为：zip_head_offset = block_index*zipBlockSize。 2）获取zip_head_offset位置对应的加密块计数，加密块计数值计算公式为：min_count = zip_head_offset/encrypted-size（加密块大小）更新iv向量的min_count值。 3）文件读指针定位到zip_head_offset，开始读取压缩块的数据，这个压缩块的数据全部读出之后，使用解压算法进行解压。 4）通过group5在解压的数据上偏移量和长度，读取group5 数据，然后再对数据进行解码。 </section> <section
