# Document Processing Subflow Settings

> [!NOTE]
> This article describes the settings available in the Document Processing Subflow included in v41. The settings available in custom flows may differ from those described here, depending on which blocks are included in those flows. To learn more about the settings for individual blocks, see Flow Blocks.

As part of our efforts to give you more precise control over your Hyperscience processes, we’ve made many of our settings configurable on the flow level.

While you can build custom flows, each instance of Hyperscience includes a Document Processing flow. To learn more about the version of this flow that comes with v41, see Document Processing Flow in V41.

The Document Processing flow contains several subflows, including the Document Processing Subflow. This article focuses on the settings available in that subflow.

## View the subflow’s settings

To view the settings of the Document Processing Subflow:

1. Click **Flows** in the left-hand sidebar, and click on the name of the Document Processing flow that contains the Document Processing Subflow whose settings you would like to view.
2. Click **Edit Flows**.
3. On the Flow Studio canvas, click the **Start Document Processing Subflow** Block.
4. Click the **Settings Type** drop-down list, and click on a setting type.

## Edit the subflow’s settings

After you’ve viewed the subflow’s settings, you can make any necessary changes, and then click **Save** in the upper-right corner of the page. You can save changes to multiple settings types at once.

## Available settings

The sections below describe the settings available for each setting type.

### File Filter

| Setting | Description | Default Value |
| --- | --- | --- |
| **All Files or Images Only** | Determines whether the filters in this block are applied to all files in submissions (**Apply to all files**) or only to image files (i.e., files whose MIME *type* is *image*) (**Apply to images only**). | **Apply to all files** |
| **Minimum Image Width (px)** | The minimum width in pixels that an image needs to have in order to be allowed by the filter. This filter applies only to images (i.e., files whose MIME *type* is *image*) and has no impact on other files. | (Blank) |
| **Minimum Image Height (px)** | The minimum height in pixels that an image needs to have in order to be allowed by the filter. This filter applies only to images (i.e., files whose MIME *type* is *image*) and has no impact on other files. | (Blank) |
| **Minimum File Size (KB)** | The minimum size in kilobytes that a file needs to have in order to be allowed by the filter. | (Blank) |
| **File Extension Action** | Select one of the following options: - **Do not filter files by extension** - **Allow only these file extensions** - **Deny files with these extensions** | **Do not filter files by extension** |
| **File Extensions** | A list of file extensions that the filter will allow or deny, based on the option selected in **File Extension Action**. Select the checkboxes for the file extensions that you would like to filter by. If **zip** is selected as a file extension, the filter will not decompress ZIP files included in submissions. Each ZIP file will be treated as an individual file, regardless of the numbers of types of files compressed within it. If there are file extensions that you want to filter by that do not appear in the drop-down list, select **other**, and enter the extensions in **Other File Extensions**. This field only appears if **Allow only these file extensions** or **Deny files with these extensions** is selected in **File Extension Action**. | (Does not appear) |
| **Other File Extensions** | A comma-separated list of file extensions that do not appear in **File Extensions**. This field only appears if **other** is selected in **File Extensions**. | (Does not appear) |

### Classification

| **Setting** | **Description** | **Default Value** |
| --- | --- | --- |
| **Structured Layout Match Threshold** | The minimum confidence score a page must have in order for it to be matched to a layout. If the page's confidence score is below this value, the system sends it to Classification Supervision (if enabled) or marks it as "No Layout Found." | 0.6 |
| **Semi-structured Classification** | Enables the management of a model that automatically classifies Semi-structured and Additional documents. | Enabled |
| **Manual Classification Supervision** | Enables Classification Supervision. | Disabled |
| **Semi-structured Classification Target Accuracy** | Your desired accuracy for the classification of Semi-structured and Additional documents. If the estimated accuracy of the model's prediction for a document is below this value, the system will send the document to Classification Supervision (if enabled) or mark it as "No Layout Found." | 99 |
| **Semi-structured Classification Grouping Logic** | Determines how multiple pages are matched to the same layout variation in a given submission will be handled. To learn more about this setting, see [Document Classification Settings](/v41/docs/document-classification-settings). | Consecutive pages as a document |
| **Semi-structured QA Sample Rate** | The percentage of documents that the system will randomly select for Classification QA. | 5 |
| **Validate Classification Using Layout ID** | Enabling this setting allows Structured documents to be matched using a layout identifier. When this setting is enabled, the system checks for a matching layout identifier in the document. If the identifier matches the expected one in the layout variation, the document is classified accordingly. If it doesn't match, the document is either sent for further review or to Document Drift Management, preventing misclassification. | Disabled |
| **Bypass Validation if Layout ID is Missing** | This setting should be enabled when certain layouts do not contain a layout identifier. It bypasses validation by layout identifier if the matched layout variation doesn’t have an identifier specified. In these cases, the bypass allows the system to continue classifying documents even without layout identifiers, ensuring that documents are still processed but not necessarily tied to a specific layout variation. | Disabled |

### Identification

| **Setting** | **Description** | **Default Value** |
| --- | --- | --- |
| **Identification Target Accuracy (Entry Level)** | Allows you to set flow-level Identification Target Accuracy values for fields and table columns (“entries”) included in the flow’s release. To enter target accuracies, click the pencil icon below **Identification Target Accuracy (Entry Level)**. ![](https://cdn.us.document360.io/87894cef-4958-4f3f-be6f-b75a78c82548/Images/Documentation/IdentificationTargetAccuracyEntryLevelV41.png) Then, click the **Target Accuracy** cell for a field or table column to enter a target accuracy for it. Click outside of the cell to save the value you entered. If you have many entries and layouts, clicking **Filter** and entering criteria for the **Layout Name**, **Entry Name**, and **Entry Type** filters may be helpful. **Automation rates for higher target accuracies** - When testing this feature using a single document and multiple target accuracies: - Due to the thresholding mechanism used in Identification, if a document is sent to Supervision for a given target accuracy, there is no guarantee that it will be sent to Supervision for all higher target accuracies. - The underlying causes is of that behavior are following design choices: - We have multiple confidence scores and thresholds for them. - We select the best combination of these thresholds for each accuracy level independently from other accuracy levels. - For example, If we send a document to Supervision because Threshold 1 for target accuracy 90%, it's possible that, for a target accuracy of 95%, Threshold 1 is less strict, and we don't send that particular document to Supervision. - When processing varied submissions and documents with multiple target accuracies over time: - Higher target accuracies for a given entry will result in lower automation rates and more Supervision tasks being created for that entry. To learn more about entry-level Identification Target Accuracy, see [Identification Settings](/v41/docs/identification-settings). | The value set in **Field Identification Target Accuracy** or **Table Identification Target Accuracy** |
| **Field Identification Target Accuracy** | Your desired accuracy for the identification of fields. If the estimated accuracy of the model's prediction for a field is below this value, the system will send the field and all its occurrences (if any) to Field ID Supervision. | 95 |
| **Table Identification Target Accuracy** | Your desired accuracy for the identification of tables. If the estimated accuracy of the model's prediction for a table is below this value, the system will send the table to Table ID Supervision. | 96 |
| **Manual Identification Supervision** | Enables Field ID Supervision and Table ID Supervision. | Enabled |
| **Field Identification Quality Assurance** | Enables Field ID Quality Assurance. If disabled, the system won't have data to retrain existing Semi-structured models, and Field Identification on new Semi-structured layouts cannot be automated. | Enabled |
| **Field Identification QA Sample Rate** | The percentage of documents that the system will randomly select for Field ID QA. This setting is only available if **Field Identification Quality Assurance** is enabled. | 5 |
| **Table Identification Quality Assurance** | Enables Table ID Quality Assurance. If disabled, the system won't have data to retrain existing Semi-structured models with tables, and Table Identification on new Semi-structured layouts cannot be automated. | Enabled |
| **Table Identification QA Sample Rate** | The percentage of documents that the system will randomly select for Table ID QA. This setting is only available if **Table Identification Quality Assurance** is enabled. | 5 |
| **Manual Identification Notification Flow** | Determines which Notification subflow is used to send Manual Identification updates to downstream systems. | Submission State Notifications |
| **Default Task Restrictions** | Determines which users can access Supervision Tasks created by the Manual Identification Block. To learn more, see [Task Restrictions Overview](/v41/docs/task-restrictions-overview). | None |

### General Transcription

| **Setting** | **Description** | **Default Value** |
| --- | --- | --- |
| **Customize Field Transcription** | Allows you to: - set flow-level Transcription Target Accuracy values for fields included in the flow’s release, and - view any Transcription Target Accuracy values set in the Field Dictionary for those fields If you enter a target accuracy for a field that already has a target accuracy set in the Field Dictionary, the value you enter here will override the one in the Field Dictionary. Note that field-specific accuracy targets apply only to fields in Structured documents. To enter target accuracies, click **Customize Field Transcription**, and click the **Target Accuracy** cell for a field to enter a target accuracy for it. Click outside of the cell to save the value you entered. If you have many fields and layouts, clicking **Filter** and entering criteria for the **Layout Name** and **Field Name** filters may be helpful. Setting a particular field’s Target Accuracy to 99%, for example, does not always guarantee that 99% accuracy will be reached all the time. The feature utilizes the Accuracy thresholds for the entire Transcription Fine-tuning model, which are valid throughout all fields and not available per field. Even so, setting a Target Accuracy for a particular entry to 99% guarantees that the entry will have a higher accuracy threshold compared to setting the Structured Text Target Accuracy for all entries. To learn more about field-level Transcription Target Accuracy, see [Transcription Accuracy and Automation](/v41/docs/transcription-accuracy-and-automation). | The value set in **Structured Text Target Accuracy**, or the **Transcription Target Accuracy** value set in the Field Dictionary (if any) |
| **Customize Transcription Target Accuracy** | For Structured documents, allows you to: - set flow-level Transcription Target Accuracy values for fields included in the flow’s release, and - view any Transcription Target Accuracy values set in the Field Dictionary for those fields For Semi-structured documents, allows you to: - set flow-level Transcription Target Accuracy values for specific fields or table columns (a.k.a. “entries”) included in the flow’s release. If you enter a target accuracy for a field in a Structured layout that already has a target accuracy set in the Field Dictionary, the value you enter here will override the one in the Field Dictionary. To enter target accuracies, click **Customize Transcription Target Accuracy**, and click the **Target Accuracy** cell for an entry to enter a target accuracy for it. Click outside of the cell to save the value you entered. If you have many entries and layouts, clicking **Filter** and entering criteria for the types and names of entries and layouts may be helpful. Setting a particular entry’s Target Accuracy to 99%, for example, does not always guarantee that 99% accuracy will be reached all the time. The feature utilizes the Accuracy thresholds for the entire Transcription Fine-tuning model, which are valid throughout all entries and not available per entry. Even so, setting a Target Accuracy for a particular entry to 99% guarantees that the entry will have a higher accuracy threshold compared to setting the Structured Text Target Accuracy or Semi-structured Text Target Accuracy for all entries. To learn more about Transcription Target Accuracy for individual entries, see [Transcription Automation and Accuracy](/v41/docs/transcription-accuracy-and-automation). | - For fields in Structured documents: - The value set in **Structured Text Target Accuracy**, or the **Transcription Target Accuracy** value set in the Field Dictionary (if any) - For fields or table columns in Semi-structured documents: - The value set in **Semi-structured Text Target Accuracy** |
| **Manual Transcription Supervision** | Enables Transcription Supervision. | Enabled |
| **Transcription Quality Assurance** | Enables Transcription Quality Assurance. If disabled, the system won't have the data needed to determine the accuracy of transcriptions. | Enabled |
| **Automatic QA Sample Rate** | If enabled, based on the QA records you have, the system automatically calculates QA sample rates for your: - Structured text, - Structured checkbox, - Structured signature, and - Semi-structured fields. When enabled, this setting overrides the following flow settings: - **Structured Text Transcription QA Sample Rate** - **Structured Checkbox Transcription QA Sample Rate** - **Structured Signature Transcription QA Sample Rate** - **Semi-structured Transcription QA Sample Rate** | Disabled |
| **Structured Text Transcription QA Sample Rate** | The percentage of text fields in Structured documents that the system randomly samples for Transcription QA. | 5 |
| **Structured Checkbox Transcription QA Sample Rate** | The percentage of checkbox fields in Structured documents that the system randomly samples for Transcription QA. | 5 |
| **Structured Signature Transcription QA Sample Rate** | The percentage of signature fields in Structured documents that the system randomly samples for Transcription QA. | 5 |
| **Semi-structured Transcription QA Sample Rate** | The percentage of fields in Semi-structured documents that the system randomly samples for Transcription QA. | 5 |
| **Table Transcription Quality Assurance** | Enables Table Transcription Quality Assurance. If disabled, the system won't have the data needed to determine the accuracy of table cell transcriptions. | Disabled |
| **Table Transcription QA Sample Rate** | The percentage of table cells that the system randomly samples for Transcription QA. | 5 |
| **Finetuning Only For Trained Layouts** | If enabled, finetuning (Transcription Automation) only uses the layouts its model was trained on. ​​If you add a new layout, the layout does not use finetuning and defaults to manually entered thresholds until a new finetuning model is trained with that layout. | Enabled |
| **Force Normalization Errors To Supervision** | This setting allows you to send fields with normalization errors to Supervision. When enabled, the normalization errors are flagged for human review, ensuring data accuracy within the platform. | Disabled |
| **Force Missing/Blank Fields To Supervision** | Fields marked as **Required** in the Layout Editor can be sent to Supervision when missing or left blank. When this setting is enabled, blank fields are sent to Transcription Supervision, while missing fields are sent to Identification Supervision. Doing so ensures that critical fields are handled within Hyperscience. | Disabled |
