Model (person) A female model posing on a typical studio shooting set. A model is a person with a role either to display commercial products (notably fashion clothing in fashion shows) or to serve as an artist's model or to pose for photography . Modelling ("modeling" in American English) is considered to be different from other types of public ...
Artificial intelligence (AI), in its broadest sense, is intelligence exhibited by machines, particularly computer systems.It is a field of research in computer science that develops and studies methods and software that enable machines to perceive their environment and use learning and intelligence to take actions that maximize their chances of achieving defined goals.

Site reliability engineering ( SRE) is a set of principles and practices that applies aspects of software engineering to IT infrastructure and operations. [ 1] SRE claims to create highly reliable and scalable software systems. Although they are closely related, SRE is slightly different from DevOps. [ 2][ 3][ 4]
A physical model (most commonly referred to simply as a model but in this context distinguished from a conceptual model) is a smaller or larger physical representation of an object, person or system. The object being modelled may be small (e.g., an atom ) or large (e.g., the Solar System ) or life-size (e.g., a fashion model displaying clothes ...
Foundation model. A foundation model, also known as large AI model, is a machine learning or deep learning model that is trained on broad data such that it can be applied across a wide range of use cases. [ 1] Foundation models have transformed artificial intelligence (AI), powering prominent generative AI applications like ChatGPT. [ 1]
Scientific modelling is an activity that produces models representing empirical objects, phenomena, and physical processes, to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate. It requires selecting and identifying relevant aspects of a situation in the real world and then developing ...
A scale model of the Tower of London. This model can be found inside the tower. A scale model of a hydropower turbine. A scale model is a physical model that is geometrically similar to an object (known as the prototype). Scale models are generally smaller than large prototypes such as vehicles, buildings, or people; but may be larger than ...
Identifiability. In statistics, identifiability is a property which a model must satisfy for precise inference to be possible. A model is identifiable if it is theoretically possible to learn the true values of this model's underlying parameters after obtaining an infinite number of observations from it. Mathematically, this is equivalent to ...
