WebDec 29, 2024 · Several different techniques exist in the practice for dealing with imbalanced dataset. The most naive class of techniques is sampling: changing the data presented to the model by undersampling common classes, oversampling (duplicating) rare classes, or both. Motivation. We’ll motivate why under- and over- sampling is useful with an example. WebDrill-core samples are a key component in mineral exploration campaigns, and their rapid and objective analysis is becoming increasingly important. Hyperspectral imaging of drill-cores is a non-destructive technique that allows for non-invasive and fast mapping of mineral phases and alteration patterns.
