Catastrophic Forgetting
(cat-a-STROF-ik for-GET-ing)
Definition
Catastrophic forgetting is when an AI model forgets old information it has learned as it learns new tasks. This occurs because the model updates its knowledge in a way that may overwrite previous information.
Where you’ll find it
In the AI development process, especially in areas where a model needs to be continuously updated or trained with new data. It is common across various AI platforms and is not specific to any templates, plans, or versions.
Common use cases
- Continuously training an AI model on new datasets without revisiting old ones.
- Developing an AI system that needs to adapt to new information in real-time.
- Models deployed in environments where the data changes frequently over time.
Things to watch out for
- The model may become less accurate over time as it forgets crucial earlier data.
- Important older information may be overwritten, even if it is still relevant.
- There is a need to balance learning new information with retaining old knowledge.
