Explosive Threat Detection System

Requirements Clarification & Assessment

Clarifying Questions:

• Context of Use: Where will the model be deployed? Is it at a border checkpoint, airport, or another type of transit location?
• Objective: Is the primary goal to prevent bombs from crossing the border or to detect them before they reach a critical area?
• Types of Items: What types of items are being screened (e.g., luggage, vehicles, or individuals)?
• Threat Types: Are we focusing on specific types of explosive devices, such as those with electronic triggers or manually activated bombs?

Data Collection:

• Historical Data: Gather past data on detected explosive threats, including the context, location, and time of detection.
• Environmental Factors: Include data on the environment around checkpoints, such as building types, population density, and traffic patterns.
• Behavioral Data: Collect information on the behavior of individuals crossing the checkpoint, such as body language and facial expressions.
• Sensor Data: Utilize data from sensors that detect materials associated with explosives, such as chemical signatures or radiological materials.

Output Specification:

• Binary Classification: The model will output a binary decision indicating the presence (1) or absence (0) of a potential explosive threat.
• Time Sensitivity: Predictions may need to be made on an hourly basis to ensure timely intervention.

Performance Metrics:

• Accuracy: Use confusion matrix metrics, focusing on minimizing false negatives (Type II errors) to avoid missing threats.
• Recall: Prioritize recall to ensure that all potential threats are flagged, even if it increases false positives.
