Explore tests

View and learn more about the tests available in the ValidMind Library, including code examples and usage of key functions.

In this notebook, we’ll dive deep into the utilities available for viewing and understanding the various tests that ValidMind provides through the tests module. Whether you’re just getting started or looking for advanced tips, you’ll find clear examples and explanations to assist you every step of the way.

Before we go into the details, let’s import the describe_test and list_tests functions from the validmind.tests module. These are the two functions that can be used to easily filter through tests and view details for individual tests.

from validmind.tests import (
    describe_test,
    list_tests,
    list_tasks,
    list_tags,
    list_tasks_and_tags,

Understanding Tags and Task Types

Effectively using ValidMind’s tests involves a deep understanding of its ‘tags’ and ‘task types’. Here’s a breakdown:

• Task Types: Represent the kind of modeling task associated with a test. For instance:

  • classification: Works with Classification Models and Datasets
  • regression: Works with Regression Models and Datasets
  • text classification: Works with Text Classification Models and Datasets
  • text summarization: Works with Text Summarization Models and Datasets

• Tags: Free-form descriptors providing more details about the test, what data and models the test is compatible with and what category the test falls into etc. Some examples include:

  • llm: Tests that work with Large Language Models
  • nlp: Tests relevant for natural language processing.
  • binary_classification: Tests for binary classification tasks.
  • forecasting: Tests for forecasting and time-series analysis.
  • tabular_data: Tests for tabular data like CSVs and Excel spreadsheets.

You can use the functions list_tasks() and list_tags() to view all the tasks and tags used for classifying all the tests available in the library:

list_tasks()

['text_qa',
 'time_series_forecasting',
 'text_generation',
 'text_summarization',
 'nlp',
 'text_classification',
 'visualization',
 'classification',
 'feature_extraction',
 'regression',
 'residual_analysis',
 'clustering']

list_tags()

['statsmodels',
 'anomaly_detection',
 'text_data',
 'data_quality',
 'ragas',
 'kmeans',
 'stationarity',
 'seasonality',
 'model_metadata',
 'zero_shot',
 'embeddings',
 'tabular_data',
 'qualitative',
 'forecasting',
 'correlation',
 'model_interpretation',
 'model_comparison',
 'feature_importance',

 'data_distribution',
 'sklearn',
 'visualization',
 'few_shot',
 'numerical_data',

 'llm',
 'statistical_test',
 'retrieval_performance',
 'model_training',
 'model_diagnosis',
 'categorical_data',
 'regression',
 'risk_analysis',
 'credit_risk']

If you want to see which tags correspond to which task type, you can use the function list_tasks_and_tags():

Searching for Specific Tests using tags and tasks

While listing all tests is valuable, there are times when you need to narrow down your search. The list_tests function offers filter, task, and tags parameters to assist in this.

If you’re targeting a specific test or tests that match a particular task type, the filter parameter comes in handy. For example, to list tests that are compatible with ‘sklearn’ models:

Programmatic Use

To work with a specific set of tests programmatically, you can store the results in a variable. For instance, let’s list all tests that are designed for Text Summarization tests and store them in text_summarization_tests for further use.

text_summarization_tests = list_tests(task="text_summarization", pretty=False)
text_summarization_tests

Delving into Test Details with describe_test

After identifying a set of potential tests, you might want to explore the specifics of an individual test. The describe_test function provides a deep dive into the details of a test. It reveals the test name, description, ID, test type, and required inputs. Below, we showcase how to describe a test using its ID:

describe_test("validmind.model_validation.sklearn.OverfitDiagnosis")

Next steps

By harnessing the functionalities presented in this guide, you should be able to easily list and filter through all of ValidMind’s available tests and find those you are interested in running against your model and/or dataset. The next step is to take the IDs of the tests you’d like to run and either create a test suite for reuse or just run them directly to try them out. See the other notebooks for a tutorial on how to do both.
