The LLM-Special Characters Ratio Filter (DLC) component of Platform for AI (PAI) is used to filter sample texts based on the ratio of special characters in the text. The input Object Storage Service (OSS) data file must be in the JSON Lines format and meet the following requirements: Each line in the file is a valid JSON object and the file consists of multiple lines of JSON objects, but the file is not a valid JSON object. For more information, see Example.

Algorithm description
The algorithm traverses each character in the text and calculates the ratio of the number of special characters to the length of the text.
The special characters include the following types: punctuation (string.punctuation), digits (string.digits), spaces (string.whitespace), emojis, and other special characters.
Configure the component
On the pipeline page of Machine Learning Designer, configure the parameters of the LLM-Special Characters Ratio Filter (DLC) component.
Tab | Parameter | Required | Description | Default value | |
Fields Setting | Target Process Field | Yes | The name of the field that you want to process. | N/A | |
Minimum Ratio | No | If the ratio of the number of special characters to the length of the text is smaller than this value, the text is filtered out. The value is of the FLOAT type. | 0 | ||
Maximum Ratio | Yes | If the ratio of the number of special characters to the length of the text is greater than this value, the text is filtered out. The value is of the FLOAT type. | N/A | ||
OSS Directory for Saving OutputData | No | The OSS directory in which the generated data is stored. If you do not specify this parameter, the default path of the workspace is used. | N/A | ||
Tuning | Number of Processes | No | The number of processes. | 8 | |
Select Resource Group | Public Resource Group | No | The instance type (CPU or GPU), number of instances, and virtual private cloud (VPC) that you want to use. | N/A | |
Dedicated resource group | No | The number of vCPUs, memory, shared memory, number of GPUs, and number of instances that you want to use. | N/A | ||
Maximum Running Duration | No | The maximum period of time for which the component can run. If this period of time is exceeded, the job is terminated. | N/A | ||
