The short answer · 19 words
In short
An adaptive algorithm changes internal parameters or its behavior during operation based on new data, feedback or changed conditions.

How much detail would you like?
Practical
Relevant in dynamic environments, drift or unknown system parameters. The term is broad and should always be explained with the concrete adjustment mechanism and goal.
Possible example: An adaptive filter continuously adjusts its coefficients in order to better suppress an interference signal in a measurement or communication application.
Possible applications: dynamic forecasting, adaptive signal processing, online learning, control and systems that respond to changing data distributions. In small and medium-sized enterprises, a clear demarcation from static rules is important.
At a glance
- Core
- “Adaptive” is not a single algorithm class with a universal formula. This refers to methods that update their parameters on the basis of observed signals, such as adaptive filters, optimizers, controls or learning methods.
- Use
- Relevant in dynamic environments, drift or unknown system parameters. The term is broad and should always be explained with the concrete adjustment mechanism and goal.
- Example
- Possible example: An adaptive filter continuously adjusts its coefficients in order to better suppress an interference signal in a measurement or communication application.
- Limits
- Use the term without a concrete adaptation mechanism; equate adaptivity with autonomy or AI; allow unstable feedback; perform adaptation without monitoring, limitations or validation.
In context
Questions about this term
Is every ML algorithm adaptive?
Not automatically in operation; many models remain static after training.
Does Adaptive Mean Autonomous?
No, adjustment rules and limits can be completely specified.

ELI5 – Explained simply
Like a filter that readjusts its settings based on new readings in order to better suppress noise.
