A default model refers to the standard or pre-existing model that is used as a starting point or baseline in a particular context or field. It serves as a default option for comparison or reference when developing or analyzing alternative models or systems. The default model represents the most common or widely accepted approach that is adopted when no specific or explicit alternative is proposed or chosen.
In various domains such as finance, economics, or computer science, a default model acts as a benchmark for understanding and evaluating alternative models, methodologies, or systems. It helps in assessing the performance, effectiveness, or efficiency of different models in relation to the default model. By comparing against the default model, one can determine the extent to which a new approach deviates from the standard or established practice.
The default model is often based on historical data, empirical evidence, theoretical assumptions, or expert consensus. It may reflect prevailing industry standards, regulatory requirements, or widely accepted conventions. However, it should be noted that a default model is not necessarily the optimal or most accurate model, but rather a commonly used starting point or reference for comparison and analysis. It provides a basis for decision-making, allowing stakeholders to evaluate the potential advantages and disadvantages of alternative models before making a final choice or adopting a new approach.
The word "default" comes from the Old French word "defaute", which means "failure" or "lack". It further developed in Middle English to mean a "failure to perform a duty" or "failure in fulfilling an obligation". The term "model", on the other hand, comes from the Latin word "modellus", meaning "a small measure" or "imitation". Over time, "model" has come to refer to a representation, template, or standard that is used as a reference or for comparison.
When combined, "default model" refers to a standard or pre-established option that is used when no other specific choice has been made or specified. It can be thought of as the standard or baseline option that is automatically applied in the absence of an alternative selection.
