Data Processing Algorithm Templates

DataFlow provides a variety of built-in data processing templates, including Basic Data Processing, Advanced Data Processing, and Data Augmentation templates. The platform will continue to expand with new templates to enhance data processing capabilities.

Users can also create custom templates or modify existing ones to build personalized data processing pipelines tailored to specific needs.

Creating a New Algorithm Template

• Modify a Built-in Template: Click Create on a built-in template card to open the template creation page.

• Create a Template from Scratch: Click Create Template button on the right to begin.

Fill in the Template Name, Task Type, and Template Description fields, and select the necessary operators and their execution order.

Note: Some operators require parameter configuration.

Once configured, click Creation Completed to start using the new template for data processing tasks.
