| When you download an engine template, it comes with the source code. All engine templates follow the same DASE architecture and they are designed to be customizable. |
| |
| You may want to customize an engine for many reasons, for example: |
| |
| * Use another algorithm, or multiple of them |
| * Read data from a different, or existing, data store |
| * Read different types of training data |
| * Transform data with another approach |
| * Add new evaluation measures |
| * Add custom business logics |
| |
| |
| To learn more about DASE, please read "[Learning DASE](/customize/)". |
| |
| After you have finished modifying the code, you can re-build and deploy the engine again with: |
| |
| ``` |
| $ pio build; pio train; pio deploy |
| ``` |
