What is gc-model-monitoring

gc-model-monitoring stands for GenCrafter Model Monitoring.

It is an open-source library for logging and monitoring any kind of data.

With gc-model-monitoring, users can generate summaries of their datasets (called profiles) to:

• Track changes in their dataset
• Create data constraints to verify data integrity
• Visualize key summary statistics

Use Cases

• Detect data drift in input features
• Detect training-serving skew and model performance degradation
• Validate data quality
• Perform exploratory data analysis
• Enable auditing and governance
• Standardize data documentation

Key Features

• 🚨 Automatic anomaly detection
• 📊 Interactive HTML reports and visualizations
• ⚡️ Real-time monitoring
• 🔍 Drift detection against baselines
• 🔧 Configurable alert thresholds
• 🤝 Integrates with MLflow and MLOps tools

Installation

pip install gc-model-monitoring

Quick Start Examples

Example 1: Basic Data Profiling

import gc_model_monitor as gcm
import pandas as pd

# Sample data with intentional issues
data = {
    "temperature": [22.1, 23.5, None, 21.9, 25.0],
    "pressure": [102.3, 101.9, 102.5, 103.1, None],
    "status": ["normal", "normal", "warning", "normal", "critical"]
}
df = pd.DataFrame(data)

# Monitor data and generate profile
profile = gcm.log_data(df).profile()
profile_view = profile.view()

# Display metrics and alerts
print("📊 Data Metrics:")
print(profile_view.to_pandas())

print("\n🚨 Data Quality Alerts:")
for alert in profile_view.get_anomalies():
    print(f"- {alert.feature}: {alert.description}")

📊 Data Metrics:
              column    null_count  completeness   min     max     mean   distinct_count
0        temperature           1          0.80   21.9    25.0   23.125         None
1           pressure           1          0.80  101.9   103.1  102.45         None
2             status           0          1.00    N/A     N/A     N/A             3

🚨 Data Quality Alerts:
- temperature: 1 missing values (20%)
- pressure: 1 missing values (20%)

Example 2: Visualization & Drift Detection

import gc_model_monitor as gcm
import pandas as pd
import matplotlib.pyplot as plt

# Create baseline from training data
train_df = pd.read_csv("train_data.csv")
train_profile = gcm.log_data(train_df).profile().view()

# Monitor production data (with drift)
prod_data = {
    "temperature": [24.5, 25.8, 26.2, 23.9, 28.0, 22.5, 27.3],
    "pressure": [100.5, 101.2, 99.8, 102.5, 98.7, 103.0, 97.5]
}
prod_df = pd.DataFrame(prod_data)
prod_profile = gcm.log_data(prod_df).profile().view()

# Generate interactive report
report = prod_profile.visualize_report(
    title="Production Drift Report",
    baseline=train_profile,
    output_path="drift_report.html"
)
report.show()

# Create drift visualization
plt.figure(figsize=(10, 4))
gcm.plot_distribution_comparison(
    feature="temperature",
    current=prod_profile,
    baseline=train_profile,
    drift_threshold=0.3
)
plt.title("Temperature Distribution Drift")
plt.savefig("temperature_drift.png")

Key Functionality

✅ Data Quality Monitoring

# Track schema changes
gcm.detect_schema_changes(current_df, training_schema)

# Monitor data completeness
gcm.track_completeness(df, threshold=0.95)

🎯 Model Performance Tracking

# Log predictions with actuals
gcm.log_predictions(
    predictions=model_predictions,
    actuals=ground_truth,
    features=feature_df
)

# Detect accuracy drop
if gcm.detect_performance_drop(current_accuracy, baseline=0.85, threshold=0.05):
    gcm.trigger_alert("Model accuracy dropped significantly!")

📈 Drift Detection

# Calculate drift scores
drift_report = gcm.calculate_drift(
    current_data=prod_df,
    reference_data=train_df,
    methods=['ks', 'psi']
)

# Monitor feature drift over time
gcm.plot_temporal_drift(
    feature="price",
    daily_profiles=[day1_view, day2_view, day3_view],
    timestamps=["2023-06-01", "2023-06-02", "2023-06-03"]
)
