-本节介绍内置异常检测算法模型的定义和使用方法。
-
-## 概述
-分析平台内置了6个异常检查模型，分为3个类别，分别是基于统计学的模型、基于数据密度的模型、以及基于深度学习的模型。在不指定异常检测使用的方法的情况下，默认调用 iqr 进行异常检测。
-
-
-### 统计学异常检测方法
-
- k-sigma<sup>[1]</sup>: 即 ***68–95–99.7 rule*** 。***k***值默认为 3，即序列均值的 3 倍标准差范围为边界，超过边界的是异常值。KSigma 要求数据整体上服从正态分布，如果一个点偏离均值 K 倍标准差，则该点被视为异常点.
-  
-|参数|说明|是否必选|默认值|
-|---|---|---|---|
-|k|标准差倍数|选填|3|
-
-
- IQR<sup>[2]</sup>：Interquartile range(IQR)，四分位距是一种衡量变异性的方法。四分位数将一个按等级排序的数据集划分为四个相等的部分。即 Q1（第 1 个四分位数）、Q2（第 2 个四分位数）和 Q3（第 3 个四分位数）。 $IQR=Q3-Q1$，对于 $v$, $Q1-(1.5 \times IQR) \le v \le Q3+(1.5 \times IQR)$ 是正常值，范围之外的是异常值。无输入参数。
-
- Grubbs<sup>[3]</sup>: Grubbs' test，即最大标准残差测试。Grubbs 通常用作检验最大值、最小值偏离均值的程度是否为异常，要求单变量数据集遵循近似标准正态分布。非正态分布数据集不能使用该方法。无输入参数。
-
- SHESD<sup>[4]</sup>： 带有季节性的 ESD 检测算法。ESD 可以检测时间序列数据的多异常点。需要指定异常点比例的上界***k***，最差的情况是至多 49.9%。数据集的异常比例一般不超过 5%
-  
-|参数|说明|是否必选|默认值|
-|---|---|---|---|
-|k|异常点在输入数据集中占比 $1 \le K \le 49.9$ |选填|5|
-
-
-### 基于数据密度的检测方法
-LOF<sup>[5]</sup>: Local Outlier Factor(LOF)，局部离群因子/局部异常因子，是 Breunig 在 2000 年提出的一种基于密度的局部离群点检测算法，该方法适用于不同类簇密度分散情况迥异的数据。根据数据点周围的数据密集情况，首先计算每个数据点的一个局部可达密度，然后通过局部可达密度进一步计算得到每个数据点的一个离群因子，该离群因子即标识了一个数据点的离群程度，因子值越大，表示离群程度越高，因子值越小，表示离群程度越低。最后，输出离群程度最大的 $topK$ 个点。
-
-
-### 基于自编码器的检测方法
-使用自动编码器的异常检测模型。可以对具有周期性的数据具有较好的检测结果。但是使用该模型需要针对输入的时序数据进行训练，同时将训练完成的模型部署到服务目录中，才能够运行与使用。

 Anode 采用类动态加载模式，在启动的时候扫描特定目录内满足约定条件的所有代码文件，并将其加载到系统中。因此，开发者只需要遵循以下几步就能完成新算法的添加工作：
 1. 开发完成符合要求的分析算法类
 2. 将代码文件放入对应目录，然后重启 Anode
-3. 使用SQL命令，向 Mnode 同步新的算法列表
+3. 使用SQL命令"CREATE ANODE"，将 Anode 添加到 TDengine
   
-此时就完成了新算法的添加工作，之后就可以直接使用SQL语句调用新算法。得益于 TDgpt 与 TDengine主进程 `taosd` 的松散耦合，Anode算法升级对 `taosd` 完全没有影响。应用系统只需要调整对应的SQL语句调用新（升级的）算法，就能够快速完成分析功能和分析算法的升级。

 这种方式能够按需扩展分析算法，极大地拓展 TDgpt 的适应范围，用户可以按需将更契合业务场景的、更准确的（预测、异常检测）分析算法动态嵌入到 TDgpt，并通过 SQL 语句进行调用。在基本不用更改应用系统代码的前提下，就能够快速完成分析功能的平滑升级。

 ## 添加具有模型的分析算法

-基于统计学的分析算法可以直接针对输入时间序列数据进行分析，整体分析流程比较快捷，但是某些深度学习算法对于输入数据的训练需要较长的时间，并且形成相应的模型。这种情况下，同一个分析算法对应不同的输入数据集有不同的分析模型。
-将具有模型的分析算法添加到 Anode 中，首先需要在 `model` 目录中建立该算法对应的目录（目录名称可自拟），将采用该算法针对不同的输入时间序列数据生成的训练模型均需要保存在该目录下，同时目录结构要在分析算法中确定，以便能够固定加载该目录下的分析模型。如下图所示，针对不同的数据集，采用自编码器（Autoencoder）训练的数据异常检测算法模型均保存在该目录下。为了确保模型能够正常读取加载，要求存储的模型使用`joblib`库进行序列化保存。

-调用已经保存的模型，需要首先调用`set_params`方法，并在参数中指定调用模型的名称 `{"model": "ad_encoder_keras"}` 即可调用该模型进行计算。调用方式如下：
+下面以自编码器（Autoencoder）为例，说明如何添加要预先训练的模型进行异常检测。
+首先我们在`model`目录中创建一个目录 -- `ad_detection`，该目录将用来保存所有使用自编码器训练的模型。然后，我们使用自编码器对 foo 表的时间序列数据进行训练，得到模型 ad_autoencoder_foo，使用 `joblib`序列化以后保存在`ad_detection` 目录中。

-```python
-def test_autoencoder_ad(self):
-    # 获取特定的算法对象
-    # ...
-    
-    # 指定调用的模型，该模型是之前针对该数据集进行训练获得
-    s.set_params({"model": "ad_encoder_keras"})
+使用 SQL 调用已经保存的模型，需要在调用参数中指定模型名称``model=ad_autoencoder_foo`，而 `algo=encoder` 是确定调用的自编码器生成的模型（这里的`encoder`说明调用的是自编码器算法模型，该名称是添加算法的时候在代码中定义）以便能够调用该模型。

-    # 执行检查动作，并返回结果
-    r = s.execute()

+目前 TDgpt 提供如下的高级分析服务：
 - 时序数据异常检测。TDengine 中定义了新的时间窗口——异常（状态）窗口——来提供异常检测服务。异常窗口可以视为一种特殊的**事件窗口（Event Window）**，即异常检测算法确定的连续异常时间序列数据所在的时间窗口。与普通事件窗口区别在于——时间窗口的起始时间和结束时间均是分析算法确定，不是用户指定的表达式判定。异常窗口使用方式与其他类型的时间窗口（例如状态窗口、会话窗口等）类似。因此时间窗口内可使用的查询操作均可应用在异常窗口上。
 - 时序数据预测。定义了一个新函数`FORECAST`，基于输入的（历史）时间序列数据调用指定（或默认）预测算法给出输入时序数据后续时间序列的**预测**数据。

+TDgpt 还为算法开发者提供了一 SDK。任何开发者只需要按照[算法开发者指南](./dev)的步骤，就可以将自己独有的时序数据预测或时序数据异常检测算法无缝集成到 TDgpt, 这样 TDengine 用户就可以通过一条 SQL 获得时序数据预测结果或是异常窗口了, 大幅降低了用户使用新的时序数据分析算法的门槛，而且让 TDengine 成为一开放的系统。

+- KEEP：表示数据文件保存的天数，缺省值为 3650，取值范围 [1, 365000]，且必须大于或等于 3 倍的 DURATION 参数值。数据库会自动删除保存时间超过 KEEP 值的数据从而释放存储空间。KEEP 可以使用加单位的表示形式，如 KEEP 100h、KEEP 10d 等，支持 m（分钟）、h（小时）和 d（天）三个单位。也可以不写单位，如 KEEP 50，此时默认单位为天。企业版支持[多级存储](https://docs.taosdata.com/tdinternal/arch/#%E5%A4%9A%E7%BA%A7%E5%AD%98%E5%82%A8)功能, 因此, 可以设置多个保存时间（多个以英文逗号分隔，最多 3 个，满足 keep 0 \<= keep 1 \<= keep 2，如 KEEP 100h,100d,3650d）; 社区版不支持多级存储功能（即使配置了多个保存时间, 也不会生效, KEEP 会取最大的保存时间）。了解更多，请点击 [关于主键时间戳](https://docs.taosdata.com/reference/taos-sql/insert/)
+- KEEP_TIME_OFFSET：自 3.2.0.0 版本生效。删除或迁移保存时间超过 KEEP 值的数据的延迟执行时间，默认值为 0 (小时)。在数据文件保存时间超过 KEEP 后，删除或迁移操作不会立即执行，而会额外等待本参数指定的时间间隔，以实现与业务高峰期错开的目的。
 - STT_TRIGGER：表示落盘文件触发文件合并的个数。开源版本固定为 1，企业版本可设置范围为 1 到 16。对于少表高频写入场景，此参数建议使用默认配置；而对于多表低频写入场景，此参数建议配置较大的值。
 - SINGLE_STABLE：表示此数据库中是否只可以创建一个超级表，用于超级表列非常多的情况。
  - 0：表示可以创建多张超级表。
