# E

**Embedding (Word Embedding)（嵌入/词嵌入）**

某个实例中所含的某个数学结构的另一个实例，例如作为另一个组的子组的组。

**Ensemble Methods（集成方法）**

在统计和机器学习中，集成方法使用多种学习算法来获得更好的预测性能，而这种性能可以单独从任何组合式学习算法中获得。与统计力学中通常是无限的统计集成不同，机器学习集成仅由一组有限的替代模型组成，但通常允许在这些替代模型之间存在更灵活的结构。

**Entropy（熵）**

随机数据源传达的平均信息量。

**Epoch（时期）**

在深度学习模型训练场景中，完整训练数据集的一次训练循环。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://wiki.aig123.com/ai-wiki/ren-gong-zhi-neng-zhuan-ye-shu-yu-biao/e.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
