Analytical Model
A mathematical or computational framework used to represent and analyze relationships between variables in drug development and manufacturing. Unlike empirical models, which rely solely on observed data, analytical models are based on theoretical principles, scientific knowledge, and mathematical equations. These models are often used to simulate and predict complex systems such as drug-receptor interactions, pharmacokinetic processes, or biopharmaceutical properties. An application for the pharmaceutical industry is describing a unit operation, such as pumping a buffer into a reaction vessel, using precise mathematical formulations.

Auto Machine Learning (AutoML)
The automated application of machine learning techniques to design, build, and deploy AI models with minimal human intervention. AutoML platforms streamline model selection, feature engineering, hyperparameter tuning, and evaluation, making machine learning more accessible. In pharmaceuticals, AutoML accelerates drug discovery, predictive modeling of patient outcomes, and manufacturing process optimization.
