Monitoring & Alerts Guide

What is AI Model Monitoring?

AI model monitoring is the continuous observation of model performance, behavior, and fairness in production environments. It helps detect issues like model drift, bias emergence, and performance degradation before they impact users.

Why Monitor AI Models?

AI models can degrade over time due to:

• Data Drift: Changes in input data distribution
• Concept Drift: Changes in the relationship between inputs and outputs
• Bias Emergence: New biases appearing in production
• Performance Degradation: Declining accuracy or other metrics
• Infrastructure Issues: System failures or resource constraints

Types of Monitoring

Performance Monitoring

Track key performance metrics:

• Accuracy: Overall prediction accuracy
• Precision/Recall: For classification tasks
• Latency: Response time for predictions
• Throughput: Number of predictions per second
• Error Rates: Frequency of prediction errors

Data Quality Monitoring

Monitor the quality and characteristics of incoming data:

• Data Distribution: Changes in feature distributions
• Missing Values: Frequency of missing data
• Data Types: Unexpected data types or formats
• Outliers: Unusual data points
• Schema Changes: Changes in data structure

Bias Monitoring

Continuously monitor for bias in model predictions:

• Demographic Parity: Equal prediction rates across groups
• Equal Opportunity: Equal true positive rates across groups
• Equalized Odds: Equal true positive and false positive rates
• Calibration: Probability calibration across groups

Business Impact Monitoring

Monitor metrics that directly impact business outcomes:

• Revenue Impact: Changes in business metrics
• User Satisfaction: Customer feedback and ratings
• Compliance Violations: Regulatory compliance issues
• Cost Metrics: Operational costs and efficiency

Setting Up Monitoring

Step 1: Define Key Metrics

Identify the most important metrics for your use case:

• Performance metrics (accuracy, latency, etc.)
• Business metrics (revenue, user satisfaction, etc.)
• Fairness metrics (bias measurements)
• Operational metrics (system health, resource usage)

Step 2: Set Baselines

Establish baseline values for each metric:

• Use historical data to determine normal ranges
• Set acceptable thresholds for each metric
• Define what constitutes an anomaly
• Document baseline assumptions and context

Step 3: Configure Alerts

Set up alerting rules:

• Define alert thresholds for each metric
• Set up different alert severity levels
• Configure alert channels (email, Slack, etc.)
• Define escalation procedures

Step 4: Implement Monitoring

Deploy monitoring infrastructure:

• Set up data collection pipelines
• Configure real-time processing
• Implement alerting systems
• Create monitoring dashboards

Alert Management

Alert Types

Fairmind supports different types of alerts:

• Performance Alerts: When accuracy drops below threshold
• Bias Alerts: When fairness metrics exceed acceptable limits
• Data Quality Alerts: When data quality issues are detected
• System Alerts: When infrastructure issues occur

Alert Severity Levels

Alerts are categorized by severity:

• Critical: Immediate action required, model may need to be taken offline
• High: Significant issue that needs attention within hours
• Medium: Issue that should be investigated within a day
• Low: Minor issue for awareness and tracking

Alert Channels

Alerts can be sent through multiple channels:

• Email: For critical alerts and daily summaries
• Slack/Teams: For real-time team notifications
• SMS: For critical alerts requiring immediate attention
• Webhook: For integration with external systems

Monitoring Dashboards

Fairmind provides comprehensive monitoring dashboards:

Real-time Metrics

• Live performance metrics
• Current bias measurements
• System health indicators
• Active alerts and their status

Historical Trends

• Performance trends over time
• Bias evolution patterns
• Data distribution changes
• Alert frequency and patterns

Model Comparison

• Compare multiple model versions
• A/B testing results
• Performance benchmarking
• Fairness comparison across models

Incident Response

When alerts are triggered, follow these steps:

Step 1: Assess the Alert

• Review the alert details and context
• Determine the severity and impact
• Check if it's a false positive
• Identify the root cause if possible

Step 2: Take Immediate Action

• For critical alerts, consider taking the model offline
• Implement temporary fixes if needed
• Notify relevant stakeholders
• Document the incident

Step 3: Investigate and Resolve

• Conduct a thorough investigation
• Identify the root cause
• Implement a permanent fix
• Test the solution thoroughly

Step 4: Learn and Improve

• Document lessons learned
• Update monitoring thresholds if needed
• Improve alerting rules
• Update incident response procedures

Best Practices

• Start with a few key metrics and expand gradually
• Set realistic thresholds based on historical data
• Regularly review and update alert rules
• Test your alerting system regularly
• Document all monitoring decisions and configurations
• Train your team on incident response procedures
• Regularly review and update monitoring dashboards
