Definition
In the context of AI and data science, quantification refers to the transformation of non-numerical data, such as text, images, or subjective opinions, into measurable numerical values. This process is essential for enabling machine learning models to process and analyze information. Techniques include tokenization for text, normalization for features, and embedding vectors for semantic representation. Without effective quantification, algorithms would lack the structured input required to identify patterns, make predictions, or generate insights from complex datasets.
Summary
Quantification is the process of expressing qualitative attributes or abstract concepts in numerical terms for analysis.
