ValidMind for model development 2 — Start the model development process

Learn how to use ValidMind for your end-to-end model documentation process with our series of four introductory notebooks. In this second notebook, you'll run tests and investigate results, then add the results or evidence to your documentation.

You'll become familiar with the individual tests available in ValidMind, as well as how to run them and change parameters as necessary. Using ValidMind's repository of individual tests as building blocks helps you ensure that a model is being built appropriately.

For a full list of out-of-the-box tests, refer to our Test descriptions or try the interactive Test sandbox.

Learn by doing

Our course tailor-made for developers new to ValidMind combines this series of notebooks with more a more in-depth introduction to the ValidMind Platform — Developer Fundamentals

Prerequisites

In order to log test results or evidence to your model documentation with this notebook, you'll need to first have:

• Registered a model within the ValidMind Platform with a predefined documentation template
• Installed the ValidMind Library in your local environment, allowing you to access all its features

Need help with the above steps?

Refer to the first notebook in this series: 1 — Set up the ValidMind Library

Setting up

Initialize the ValidMind Library

First, let's connect up the ValidMind Library to our model we previously registered in the ValidMind Platform:

1. In a browser, log in to ValidMind.

2. In the left sidebar, navigate to Inventory and select the model you registered for this "ValidMind for model development" series of notebooks.

3. Go to Getting Started and click Copy snippet to clipboard.

Next, load your model identifier credentials from an .env file or replace the placeholder with your own code snippet:

# Make sure the ValidMind Library is installed

%pip install -q validmind

# Load your model identifier credentials from an `.env` file

%load_ext dotenv
%dotenv .env

# Or replace with your code snippet

import validmind as vm

vm.init(
    # api_host="...",
    # api_key="...",
    # api_secret="...",
    # model="...",
)

Note: you may need to restart the kernel to use updated packages.

⚠️ This kernel is running an older version of validmind (2.8.28) than the latest version installed on your system (2.8.29). You may need to restart the kernel if you are experiencing issues.

Import sample dataset

Then, let's import the public Bank Customer Churn Prediction dataset from Kaggle.

In our below example, note that:

• The target column, Exited has a value of 1 when a customer has churned and 0 otherwise.
• The ValidMind Library provides a wrapper to automatically load the dataset as a Pandas DataFrame object. A Pandas Dataframe is a two-dimensional tabular data structure that makes use of rows and columns.

from validmind.datasets.classification import customer_churn as demo_dataset

print(
    f"Loaded demo dataset with: \n\n\t• Target column: '{demo_dataset.target_column}' \n\t• Class labels: {demo_dataset.class_labels}"
)

raw_df = demo_dataset.load_data()
raw_df.head()

Loaded demo dataset with: 

    • Target column: 'Exited' 
    • Class labels: {'0': 'Did not exit', '1': 'Exited'}

Identify qualitative tests

Next, let's say we want to do some data quality assessments by running a few individual tests.

Use the vm.tests.list_tests() function introduced by the first notebook in this series in combination with vm.tests.list_tags() and vm.tests.list_tasks() to find which prebuilt tests are relevant for data quality assessment:

• tasks represent the kind of modeling task associated with a test. Here we'll focus on classification tasks.
• tags are free-form descriptions providing more details about the test, for example, what category the test falls into. Here we'll focus on the data_quality tag.

# Get the list of available task types

You can pass tags and tasks as parameters to the vm.tests.list_tests() function to filter the tests based on the tags and task types.

For example, to find tests related to tabular data quality for classification models, you can call list_tests() like this:

vm.tests.list_tests(task="classification", tags=["tabular_data", "data_quality"])

Initialize the ValidMind datasets

With the individual tests we want to run identified, the next step is to connect your data with a ValidMind Dataset object. This step is always necessary every time you want to connect a dataset to documentation and produce test results through ValidMind, but you only need to do it once per dataset.

Initialize a ValidMind dataset object using the init_dataset function from the ValidMind (vm) module. For this example, we'll pass in the following arguments:

• dataset — The raw dataset that you want to provide as input to tests.
• input_id — A unique identifier that allows tracking what inputs are used when running each individual test.
• target_column — A required argument if tests require access to true values. This is the name of the target column in the dataset.

# vm_raw_dataset is now a VMDataset object that you can pass to any ValidMind test
vm_raw_dataset = vm.init_dataset(
    dataset=raw_df,
    input_id="raw_dataset",
    target_column="Exited",
)

Running tests

Now that we know how to initialize a ValidMind dataset object, we're ready to run some tests!

You run individual tests by calling the run_test function provided by the validmind.tests module. For the examples below, we'll pass in the following arguments:

• test_id — The ID of the test to run, as seen in the ID column when you run list_tests.
• params — A dictionary of parameters for the test. These will override any default_params set in the test definition.

Run tabular data tests

The inputs expected by a test can also be found in the test definition — let's take validmind.data_validation.DescriptiveStatistics as an example.

Note that the output of the describe_test() function below shows that this test expects a dataset as input:

vm.tests.describe_test("validmind.data_validation.DescriptiveStatistics")

Now, let's run a few tests to assess the quality of the dataset:

result = vm.tests.run_test(
    test_id="validmind.data_validation.DescriptiveStatistics",
    inputs={"dataset": vm_raw_dataset},
)

result2 = vm.tests.run_test(
    test_id="validmind.data_validation.ClassImbalance",
    inputs={"dataset": vm_raw_dataset},
    params={"min_percent_threshold": 30},
)

The output above shows that the class imbalance test did not pass according to the value we set for min_percent_threshold.

To address this issue, we'll re-run the test on some processed data. In this case let's apply a very simple rebalancing technique to the dataset:

import pandas as pd

raw_copy_df = raw_df.sample(frac=1)  # Create a copy of the raw dataset

# Create a balanced dataset with the same number of exited and not exited customers
exited_df = raw_copy_df.loc[raw_copy_df["Exited"] == 1]
not_exited_df = raw_copy_df.loc[raw_copy_df["Exited"] == 0].sample(n=exited_df.shape[0])

balanced_raw_df = pd.concat([exited_df, not_exited_df])
balanced_raw_df = balanced_raw_df.sample(frac=1, random_state=42)

With this new balanced dataset, you can re-run the individual test to see if it now passes the class imbalance test requirement.

As this is technically a different dataset, remember to first initialize a new ValidMind Dataset object to pass in as input as required by run_test():

# Register new data and now 'balanced_raw_dataset' is the new dataset object of interest
vm_balanced_raw_dataset = vm.init_dataset(
    dataset=balanced_raw_df,
    input_id="balanced_raw_dataset",
    target_column="Exited",
)

# Pass the initialized `balanced_raw_dataset` as input into the test run
result = vm.tests.run_test(
    test_id="validmind.data_validation.ClassImbalance",
    inputs={"dataset": vm_balanced_raw_dataset},
    params={"min_percent_threshold": 30},
)

Utilize test output

You can utilize the output from a ValidMind test for further use, for example, if you want to remove highly correlated features. Removing highly correlated features helps make the model simpler, more stable, and easier to understand.

Below we demonstrate how to retrieve the list of features with the highest correlation coefficients and use them to reduce the final list of features for modeling.

First, we'll run validmind.data_validation.HighPearsonCorrelation with the balanced_raw_dataset we initialized previously as input as is for comparison with later runs:

corr_result = vm.tests.run_test(
    test_id="validmind.data_validation.HighPearsonCorrelation",
    params={"max_threshold": 0.3},
    inputs={"dataset": vm_balanced_raw_dataset},
)

The output above shows that the test did not pass according to the value we set for max_threshold.

corr_result is an object of type TestResult. We can inspect the result object to see what the test has produced:

print(type(corr_result))
print("Result ID: ", corr_result.result_id)
print("Params: ", corr_result.params)
print("Passed: ", corr_result.passed)
print("Tables: ", corr_result.tables)

<class 'validmind.vm_models.result.result.TestResult'>
Result ID:  validmind.data_validation.HighPearsonCorrelation
Params:  {'max_threshold': 0.3}
Passed:  False
Tables:  [ResultTable]

Let's remove the highly correlated features and create a new VM dataset object.

We'll begin by checking out the table in the result and extracting a list of features that failed the test:

# Extract table from `corr_result.tables`
features_df = corr_result.tables[0].data
features_df

	Columns	Coefficient	Pass/Fail
0	(Age, Exited)	0.3265	Fail
1	(IsActiveMember, Exited)	-0.1984	Pass
2	(Balance, NumOfProducts)	-0.1756	Pass
3	(Balance, Exited)	0.1545	Pass
4	(NumOfProducts, Exited)	-0.0518	Pass
5	(NumOfProducts, IsActiveMember)	0.0498	Pass
6	(CreditScore, Exited)	-0.0484	Pass
7	(HasCrCard, IsActiveMember)	-0.0425	Pass
8	(CreditScore, Age)	-0.0417	Pass
9	(Tenure, IsActiveMember)	-0.0403	Pass

# Extract list of features that failed the test
high_correlation_features = features_df[features_df["Pass/Fail"] == "Fail"]["Columns"].tolist()
high_correlation_features

['(Age, Exited)']

Next, extract the feature names from the list of strings (example: (Age, Exited) > Age):

high_correlation_features = [feature.split(",")[0].strip("()") for feature in high_correlation_features]
high_correlation_features

['Age']

Now, it's time to re-initialize the dataset with the highly correlated features removed.

Note the use of a different input_id. This allows tracking the inputs used when running each individual test.

# Remove the highly correlated features from the dataset
balanced_raw_no_age_df = balanced_raw_df.drop(columns=high_correlation_features)

# Re-initialize the dataset object
vm_raw_dataset_preprocessed = vm.init_dataset(
    dataset=balanced_raw_no_age_df,
    input_id="raw_dataset_preprocessed",
    target_column="Exited",
)

Re-running the test with the reduced feature set should pass the test:

corr_result = vm.tests.run_test(
    test_id="validmind.data_validation.HighPearsonCorrelation",
    params={"max_threshold": 0.3},
    inputs={"dataset": vm_raw_dataset_preprocessed},
)

You can also plot the correlation matrix to visualize the new correlation between features:

corr_result = vm.tests.run_test(
    test_id="validmind.data_validation.PearsonCorrelationMatrix",
    inputs={"dataset": vm_raw_dataset_preprocessed},
)

Documenting test results

Now that we've done some analysis on two different datasets, we can use ValidMind to easily document why certain things were done to our raw data with testing to support it.

Every test result returned by the run_test() function has a .log() method that can be used to send the test results to the ValidMind Platform:

• When using run_documentation_tests(), documentation sections will be automatically populated with the results of all tests registered in the documentation template.
• When logging individual test results to the platform, you'll need to manually add those results to the desired section of the model documentation.

To demonstrate how to add test results to your model documentation, we'll populate the entire Data Preparation section of the documentation using the clean vm_raw_dataset_preprocessed dataset as input, and then document an additional individual result for the highly correlated dataset vm_balanced_raw_dataset.

Run and log multiple tests

run_documentation_tests() allows you to run multiple tests at once and automatically log the results to your documentation. Below, we'll run the tests using the previously initialized vm_raw_dataset_preprocessed as input — this will populate the entire Data Preparation section for every test that is part of the documentation template.

For this example, we'll pass in the following arguments:

• inputs: Any inputs to be passed to the tests.
• config: A dictionary <test_id>:<test_config> that allows configuring each test individually. Each test config requires the following:
  • params: Individual test parameters.
  • inputs: Individual test inputs. This overrides any inputs passed from the run_documentation_tests() function.

When including explicit configuration for individual tests, you'll need to specify the inputs even if they mirror what is included in your global configuration.

# Individual test config with inputs specified
test_config = {
    "validmind.data_validation.ClassImbalance": {
        "params": {"min_percent_threshold": 30},
        "inputs": {"dataset": vm_raw_dataset_preprocessed},
    },
    "validmind.data_validation.HighPearsonCorrelation": {
        "params": {"max_threshold": 0.3},
        "inputs": {"dataset": vm_raw_dataset_preprocessed},
    },
}

# Global test config
tests_suite = vm.run_documentation_tests(
    inputs={
        "dataset": vm_raw_dataset_preprocessed,
    },
    config=test_config,
    section=["data_preparation"],
)

Run and log an individual test

Next, we'll use the previously initialized vm_balanced_raw_dataset (that still has a highly correlated Age column) as input to run an individual test, then log the result to the ValidMind Platform.

When running individual tests, you can use a custom result_id to tag the individual result with a unique identifier:

• This result_id can be appended to test_id with a : separator.
• The balanced_raw_dataset result identifier will correspond to the balanced_raw_dataset input, the dataset that still has the Age column.

result = vm.tests.run_test(
    test_id="validmind.data_validation.HighPearsonCorrelation:balanced_raw_dataset",
    params={"max_threshold": 0.3},
    inputs={"dataset": vm_balanced_raw_dataset},
)
result.log()

2025-07-30 00:18:36,506 - INFO(validmind.vm_models.result.result): Test driven block with result_id validmind.data_validation.HighPearsonCorrelation:balanced_raw_dataset does not exist in model's document

Note the output returned indicating that a test-driven block doesn't currently exist in your model's documentation for this particular test ID.

That's expected, as when we run individual tests the results logged need to be manually added to your documentation within the ValidMind Platform.

Add individual test results to model documentation

With the test results logged, let's head to the model we connected to at the beginning of this notebook and insert our test results into the documentation (Need more help?):

1. From the Inventory in the ValidMind Platform, go to the model you connected to earlier.

2. In the left sidebar that appears for your model, click Documentation.

3. Locate the Data Preparation section and click on 2.3. Correlations and Interactions to expand that section.

4. Hover under the Pearson Correlation Matrix content block until a horizontal dashed line with a + button appears, indicating that you can insert a new block.

   
   
   

5. Click + and then select Test-Driven Block under FROM LIBRARY:

   • Click on VM Library under TEST-DRIVEN in the left sidebar.
   • In the search bar, type in HighPearsonCorrelation.
   • Select HighPearsonCorrelation:balanced_raw_dataset as the test.

   A preview of the test gets shown:

   
   
   

6. Finally, click Insert 1 Test Result to Document to add the test result to the documentation.

   Confirm that the individual results for the high correlation test has been correctly inserted into section 2.3. Correlations and Interactions of the documentation.

7. Finalize the documentation by editing the test result's description block to explain the changes you made to the raw data and the reasons behind them as shown in the screenshot below:

   

Model testing

So far, we've focused on the data assessment and pre-processing that usually occurs prior to any models being built. Now, let's instead assume we have already built a model and we want to incorporate some model results into our documentation.

Train simple logistic regression model

Using ValidMind tests, we'll train a simple logistic regression model on our dataset and evaluate its performance by using the LogisticRegression class from the sklearn.linear_model.

To start, let's grab the first few rows from the balanced_raw_no_age_df dataset with the highly correlated features removed we initialized earlier:

balanced_raw_no_age_df.head()

	CreditScore	Geography	Gender	Tenure	Balance	NumOfProducts	HasCrCard	IsActiveMember	EstimatedSalary	Exited
1662	642	France	Male	7	0.00	2	1	0	102083.78	0
5250	707	France	Female	2	58036.33	1	1	1	83335.78	0
1274	589	France	Male	2	0.00	1	1	0	79915.28	0
5848	650	Spain	Male	4	194532.66	1	1	0	171045.31	1
3548	615	France	Male	6	0.00	1	1	1	27011.80	1

Before training the model, we need to encode the categorical features in the dataset:

• Use the OneHotEncoder class from the sklearn.preprocessing module to encode the categorical features.
• The categorical features in the dataset are Geography and Gender.

balanced_raw_no_age_df = pd.get_dummies(
    balanced_raw_no_age_df, columns=["Geography", "Gender"], drop_first=True
)
balanced_raw_no_age_df.head()

	CreditScore	Tenure	Balance	NumOfProducts	HasCrCard	IsActiveMember	EstimatedSalary	Exited	Geography_Germany	Geography_Spain	Gender_Male
1662	642	7	0.00	2	1	0	102083.78	0	False	False	True
5250	707	2	58036.33	1	1	1	83335.78	0	False	False	False
1274	589	2	0.00	1	1	0	79915.28	0	False	False	True
5848	650	4	194532.66	1	1	0	171045.31	1	False	True	True
3548	615	6	0.00	1	1	1	27011.80	1	False	False	True

We'll split our preprocessed dataset into training and testing, to help assess how well the model generalizes to unseen data:

• We start by dividing our balanced_raw_no_age_df dataset into training and test subsets using train_test_split, with 80% of the data allocated to training (train_df) and 20% to testing (test_df).
• From each subset, we separate the features (all columns except "Exited") into X_train and X_test, and the target column ("Exited") into y_train and y_test.

from sklearn.model_selection import train_test_split

train_df, test_df = train_test_split(balanced_raw_no_age_df, test_size=0.20)

X_train = train_df.drop("Exited", axis=1)
y_train = train_df["Exited"]
X_test = test_df.drop("Exited", axis=1)
y_test = test_df["Exited"]

Then using GridSearchCV, we'll find the best-performing hyperparameters or settings and save them:

from sklearn.linear_model import LogisticRegression

# Logistic Regression grid params
log_reg_params = {
    "penalty": ["l1", "l2"],
    "C": [0.001, 0.01, 0.1, 1, 10, 100, 1000],
    "solver": ["liblinear"],
}

# Grid search for Logistic Regression
from sklearn.model_selection import GridSearchCV

grid_log_reg = GridSearchCV(LogisticRegression(), log_reg_params)
grid_log_reg.fit(X_train, y_train)

# Logistic Regression best estimator
log_reg = grid_log_reg.best_estimator_

Initialize model evaluation objects

The last step for evaluating the model's performance is to initialize the ValidMind Dataset and Model objects in preparation for assigning model predictions to each dataset.

# Initialize the datasets into their own dataset objects
vm_train_ds = vm.init_dataset(
    input_id="train_dataset_final",
    dataset=train_df,
    target_column="Exited",
)

vm_test_ds = vm.init_dataset(
    input_id="test_dataset_final",
    dataset=test_df,
    target_column="Exited",
)

You'll also need to initialize a ValidMind model object (vm_model) that can be passed to other functions for analysis and tests on the data for each of our three models.

You simply initialize this model object with vm.init_model():

# Register the model
vm_model = vm.init_model(log_reg, input_id="log_reg_model_v1")

Assign predictions

Once the model has been registered you can assign model predictions to the training and testing datasets.

• The assign_predictions() method from the Dataset object can link existing predictions to any number of models.
• This method links the model's class prediction values and probabilities to our vm_train_ds and vm_test_ds datasets.

If no prediction values are passed, the method will compute predictions automatically:

vm_train_ds.assign_predictions(model=vm_model)
vm_test_ds.assign_predictions(model=vm_model)

In this next example, we'll focus on running the tests within the Model Development section of the model documentation. Only tests associated with this section will be executed, and the corresponding results will be updated in the model documentation.

• Note the additional config that is passed to run_documentation_tests() — this allows you to override inputs or params in certain tests.
• In our case, we want to explicitly use the vm_train_ds for the validmind.model_validation.sklearn.ClassifierPerformance:in_sample test, since it's supposed to run on the training dataset and not the test dataset.

test_config = {
    "validmind.model_validation.sklearn.ClassifierPerformance:in_sample": {
        "inputs": {
            "dataset": vm_train_ds,
            "model": vm_model,
        },
    }
}
results = vm.run_documentation_tests(
    section=["model_development"],
    inputs={
        "dataset": vm_test_ds,  # Any test that requires a single dataset will use vm_test_ds
        "model": vm_model,
        "datasets": (
            vm_train_ds,
            vm_test_ds,
        ),  # Any test that requires multiple datasets will use vm_train_ds and vm_test_ds
    },
    config=test_config,
)

In summary

In this second notebook, you learned how to:

• Import a sample dataset
• Identify which tests you might want to run with ValidMind
• Initialize ValidMind datasets and model objects
• Run individual tests
• Utilize the output from tests you've run
• Log test results from sets of or individual tests as evidence to the ValidMind Platform
• Add supplementary individual test results to your documentation
• Assign model predictions to your ValidMind model objects

Next steps

Integrate custom tests

Now that you're familiar with the basics of using the ValidMind Library to run and log tests to provide evidence for your model documentation, let's learn how to incorporate your own custom tests into ValidMind: 3 — Integrate custom tests
