G.O.D. Framework

Introduction

The ai_edge_case_handling.py module focuses on detecting, logging, and handling edge cases or anomalies within AI systems. Edge cases—unexpected or rare behaviors—often challenge AI models during real-world deployment. This module empowers the G.O.D Framework to gracefully resolve such cases, ensuring robustness under diverse operating conditions.

Its primary aim is to predict, contain, and minimize disruptions when handling rare behaviors, safeguarding reliability and user trust.

Purpose

• Edge Case Detection: Identify unusual behaviors or data outside the normal distribution.
• Error Correction: Apply predefined correction strategies for known errors.
• Dynamic Resilience: Adapt AI behavior dynamically to unexpected scenarios.
• Continuous Monitoring: Integrate anomaly detection pipelines with real-time operations.
• Log Rare Events: Generate detailed logs and insights for debugging and retraining models to improve edge case handling.

Key Features

• Anomaly Detection: Leverages statistical techniques, clustering methods, and AI for anomaly identification.
• Error Recovery: Implements fallback strategies for known edge cases based on custom-defined rules.
• Self-Healing Mechanism: Assigns mitigation plans to resolve errors autonomously.
• Case Logging: Maintains a structured log of all edge case occurrences for analysis and audits.
• Integration Ready: Fully compatible with larger pipelines (e.g., inference, deployment, monitoring).

Logic and Implementation

The ai_edge_case_handling.py script uses a combination of statistical detection and rule-based interventions. It integrates with monitoring systems to extract real-time data and identify deviations. Once an edge case is identified, the system resolves it by either applying correction rules, activating a fallback, or triggering a self-healing routine.

An example implementation of the module is as follows:

            import numpy as np
            import logging

            class EdgeCaseHandler:
                """
                This class handles rare, edge-case scenarios during AI model inference or data processing pipelines.
                """

                def __init__(self, threshold=3.0):
                    """
                    Initialize the handler with a threshold for anomaly detection.
                    :param threshold: Number of standard deviations to classify anomalies.
                    """
                    self.threshold = threshold
                    self.logger = self.setup_logger()

                    """

                    logger = logging.getLogger("EdgeCaseHandler")
                    handler = logging.StreamHandler()

                    handler.setFormatter(formatter)
                    logger.addHandler(handler)
                    logger.setLevel(logging.INFO)
                    return logger

                    """

                    if outliers:
                        self.logger.warning(f"Detected outliers: {outliers}")
                    return outliers

                def handle_edge_case(self, case_id, recovery_action="log"):

            if __name__ == "__main__":
                handler = EdgeCaseHandler(threshold=2.5)

Dependencies

This module relies on the following libraries:

• numpy: For statistical calculations (e.g., mean, standard deviation).
• logging: For structured logging to handle anomalies.

Usage

The module can be used to proactively handle edge cases and anomalies in various scenarios. Key usage steps include:

1. Initialize the EdgeCaseHandler class.
2. Feed input data to detect_outliers() to identify anomalies.
3. Use handle_edge_case() to execute specific mitigation strategies where necessary.

            handler = EdgeCaseHandler(threshold=3.0)
            anomalies = handler.detect_outliers([10, 12, 300, 11, 13])
            handler.handle_edge_case(case_id=42, recovery_action="notify")
