Algorithmic Bias andFairness

AI models learn from training data. If that data reflects historical biases (np., underrepretion of certain demographic groups, or human coder biases in labeling), the model will perpetuate andd potentially ampefify those biases. For example, a sentiment model creatid mosty on English-language responses may misinterpret sarum or dialect- specific expressions, leading to systematic misclassificational of certain populations.
