ML Archetypes location

caution

Before generating a new project, configure a local environment.

Archetypes are available from Work.AI public Nexus. A separate repository—https://repository.workfusion.com/content/repositories/archetypes/—is dedicated to various Archetypes. ML Archetypes are located in the com.workfusion.ml package.

If you cannot use the Work.AI public Nexus due to your company's security policy, use the on-prem platform's Nexus. It comes with each deployment and includes out-of-the-box ML Archetypes for a specific platform version.

ML quickstart Archetypes

The Machine Learning (ML) quickstart Archetype is a Maven project allowing simple model implementation and comprising a module for deployment to the server platform environment via Asset Bundle migration API.

The following ML quickstart Archetypes are available:

Name	Search Engine	Use when
ml-ie-quickstart	2.0	You build a Java-based Information Extraction model and want to have a minimalistic working example as a starting point. The example can compile, train, and test out of the box.
ml-classification-quickstart	2.0	You build a Java-based Classification model and want a minimalistic working example as a starting point. The example can compile, train, and test out of the box.
ml-python-classification-quickstart-archetype		You build a Python-based Classification model and want a minimalistic working example as a starting point. The example can compile, train, and test out of the box.

To generate a Maven project with one of the above Archetypes, execute the following command in the command-line interface:

mvn archetype:generate -DarchetypeGroupId=com.workfusion.ml -DarchetypeArtifactId=ml-ie-quickstart -DarchetypeVersion=<ML SDK version>

The ML SDK version value in the above command should correspond to your platform version. See the View AutoML compatibility matrix | AutoML SDK and Work.AI platform versions.

Provide the following parameters for an Archetype in the interactive mode:

groupId: group identifier of your artifact. Set a base package, for example, com.mycompany.
artifactId: unique identifier of your artifact. Use only lowercase Latin symbols without spaces and special characters, for example, ml-ie-quick-test.
version: artifact version. Avoid using SNAPSHOT versions. Use the RELEASE type, for example, 1.0.0.
package: default package for code generation. Use only lowercase Latin symbols without spaces and special characters, for example, mlieqt.

The generated project stub has two modules:

[ARTIFACT_ID]-ml-sdk contains an ML SDK model configuration, a training set, a test set, and Java executable classes for training and testing.
[ARTIFACT_ID]-package provides a structure for building of the model bundle artifact.

ML raw Archetypes

To generate an empty raw project stub in Maven, choose one of the Archetypes from the table below, depending on the model type and Search Engine version.

Name	Search Engine	Use when
ml-sdk-ie-se-20-archetype	2.0	You build a Java-based Information Extraction model based on a generic model or from scratch with SE 2.0.
ml-sdk-ie-se-30-archetype	3.0	You build a Java-based Information Extraction model based on a generic model or from scratch with SE 3.0.
ml-sdk-classification-se-20-archetype	2.0	You build a Java-based Classification model based on a generic model or from scratch
ml-sdk-binary-classification-se-20-archetype	2.0	You build a Java-based Binary Classification model based on a generic model or from scratch.
ml-sdk-python-ie-archetype		You want to use a custom Python Information Extraction model in Work.AI.
ml-python-ie-archetype-v2		You want to use a pure Python (without Java code) Information Extraction model in Work.AI.
ml-python-classification-archetype		You want to use a custom Python Classification model in Work.AI.
ml-python-classification-archetype-v2		You want to use a pure Python (without Java code) Classification model in Work.AI.
ml-python-image-archetype		You want to use a custom Python image-based model to solve an ML problem of transforming input images in Work.AI.
ml-python-image-archetype-v2		You want to use a pure Python (without Java code) image-based model to solve an ML problem of transforming input images in Work.AI.

To generate a Maven project with one of the above Archetypes, execute the following command in the command-line interface:

mvn archetype:generate -DarchetypeGroupId=com.workfusion.ml -DarchetypeArtifactId=ml-sdk-ie-se-20-archetype -DarchetypeVersion=<ML SDK version>

The ML SDK version value in the above command should correspond to your platform version. See the View AutoML compatibility matrix | AutoML SDK and Work.AI platform versions.

Provide the following parameters for an Archetype in the interactive mode:

groupId: group identifier of your artifact.
artifactId: unique identifier of your artifact.
version: artifact version.
package: default package for code generation.
importConfigurationFromGenericModel: y for a generic model configuration or n for an empty model without configuration.
modelClassName: class name of your model.
modelCode: pipeline (hyper model) code; only [a-z, 0-9, _, -] are allowed.
modelDescription: pipeline (hyper model) description used as a hint during automation setup.
modelTitle: pipeline (hyper model) title used as a value in the automation setup drop-down box.
modelVersion: pipeline (hyper model) version.

Your pipeline (hyper model) stub is generated. It is a Maven project you can import to your preferred Java IDE.

The generated project stub has two modules:

[ARTIFACT_ID]-ml-sdk contains an ML SDK model configuration, Java executable classes for training and testing.
[ARTIFACT_ID]-package provides a structure for building of the model bundle artifact.

Import to IDE

To import a generated Maven project to Eclipse or IntelliJ IDEA, follow the steps below:

Choose Import Maven project.
Select the root pom.xml from the directory where you generated the AutoML project with the Archetype.

Check project artifacts

The generated stub should contain the following classes:

<%artifact-name%>Model: class with a custom pipeline (hyper model).
In the class, you can find a basic configuration of your pipeline (hyper model): code, version, title, and so on. It also contains a generated ModelConfiguration annotation with a pre-generated model configuration.
The generated pipeline (hyper model) extends one of the generic models:
- GenericIeHyperModel for IE models
- GenericMultiClassificationHyperModel for Classification models
<%artifact-name%>Configuration: class comprising the processor, featureExtractors, annotators methods where you can define your model configuration.
PostProcessorExample: post-processor example.
FeatureExtractorExample: feature extractor example.
ModelTrainingRunner: class for a local model training run.
ModelProcessingRunner: class for a local model execution run to develop or debug post-processing.
