| ## 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 | |
