CloudTimeSeriesData

## Intro
The data organization follows TFB format: https://github.com/decisionintelligence/TFB.

## TFB data format

TFB stores time series in a format of three column long tables, which we will introduce below：

### Format Introduction

**First column: date** (the exact column name is required, the same applies below.)

- The columns stores the time information in the time series, which can be in either of the following formats:
- Timestamps in string, datetime, or other types that are compatible with pd.to_datetime;
- Integers starting from 1, e.g. 1, 2, 3, 4, 5, ...

**Second column: data**

- This column stores the series values corresponding to the timestamps.

**Third column: cols**

- This column stores the column name (variable name).

### Multivariate time series example:

**A common time series in wide table format:**

| date | channel1 | channel2 | channel3 |
| ---- | -------- | -------- | -------- |
| 1 | 0.1 | 1 | 10 |
| 2 | 0.2 | 2 | 20 |
| 3 | 0.3 | 3 | 30 |

**Convert to TFB format:**

| date | data | cols |
| ---- | ---- | -------- |
| 1 | 0.1 | channel1 |
| 2 | 0.2 | channel1 |
| 3 | 0.3 | channel1 |
| 1 | 1 | channel2 |
| 2 | 2 | channel2 |
| 3 | 3 | channel2 |
| 1 | 10 | channel3 |
| 2 | 20 | channel3 |
| 3 | 30 | channel3 |

## 简介
本数据集的数据组织遵循TFB格式：https://github.com/decisionintelligence/TFB。

## TFB数据格式

TFB以三列长表的形式存储时间序列，下文将详细介绍其规范：

### 格式说明

**第一列：date（列名必须严格使用该名称，下文同理）**

- 该列存储时间序列的时间信息，支持以下两种格式：
- 字符串、datetime或其他可与`pd.to_datetime`兼容的时间戳类型；
- 从1开始的整数序列，例如1、2、3、4、5……

**第二列：data**

- 该列存储对应时间戳的序列值。

**第三列：cols**

- 该列存储列名（变量名）。

### 多变量时间序列示例

**宽表格式下的典型时间序列：**

| date | channel1 | channel2 | channel3 |
| ---- | -------- | -------- | -------- |
| 1 | 0.1 | 1 | 10 |
| 2 | 0.2 | 2 | 20 |
| 3 | 0.3 | 3 | 30 |

**转换为TFB格式后的结果：**

| date | data | cols |
| ---- | ---- | -------- |
| 1 | 0.1 | channel1 |
| 2 | 0.2 | channel1 |
| 3 | 0.3 | channel1 |
| 1 | 1 | channel2 |
| 2 | 2 | channel2 |
| 3 | 3 | channel2 |
| 1 | 10 | channel3 |
| 2 | 20 | channel3 |
| 3 | 30 | channel3 |
