Querying the List of a Processing Task

Function

This API is used to obtain processing tasks, including feature analysis tasks and data processing tasks. You can specify the task_type parameter to obtain a specific type of tasks.

  • During data feature analysis, images or target bounding boxes are analyzed based on image features, such as blurs and brightness to draw visualized curves to assist in dataset processing.

  • Data processing is used to extract valuable data from a large amount of disordered, difficult-to-understand data. Data processing includes data validation, data cleansing, data selection, and data augmentation.

  • Data validation indicates that the dataset is verified to ensure data accuracy.

  • Data cleansing refers to the process of denoising, correcting, or supplementing data.

  • Data selection indicates the process of selecting data subsets from full data.

  • Data augmentation indicates that data volume is increased through simple data amplification operations such as scaling, cropping, transformation, and composition.

Debugging

You can debug this API through automatic authentication in or use the SDK sample code generated by API Explorer.
