Understanding Regression: Theory to Real-World Use
When we talk about regression problems, we’re asking a model: “How much of this property is present?” Unlike classification, which assigns items to categories, regression predicts continuous values, such as fat in olives, moisture in meat, or the concentration of an active ingredient in a medicine. At NIRLAB, predictions are

Critical On-Site Detection of Explosive Precursors
Homemade explosives (HMEs) are attractive to criminals and terrorists due to accessible online recipes, readily available equipment, and the ease of obtaining precursor materials. To counter this, EU Regulation 2019/1148 restricts access to high concentrations of “Restricted Precursors” and monitors sales of “Reportable Explosives Precursors”. Classification as an explosive precursor

Understanding Classification Problems: Theory to Real-World applications with NIRLAB
When we talk about classification problems, we’re essentially asking a model to decide: “Which group does this item belong to?” Unlike prediction problems that estimate continuous values, classification focuses on discrete categories, such as whether a product is genuine or counterfeit, or whether a plant is ready to harvest or

The Hidden Dangers: Cutting Agents in Cocaine
Following our insightful exploration in “Cocaine Analysis – Challenges and Opportunities“, we delve deeper into a critical aspect that plays a pivotal role in the global cocaine trade: the cutting agents. These substances, mixed with cocaine to increase volume, alter potency, or both, significantly impact the drug’s purity, efficacy, and
