When the Same Musical Knowledge Forgets Differently: A Clean Probe of Pathway-Dependent Forgetting
Researchers have investigated how the acquisition route of knowledge in multimodal AI models affects its susceptibility to forgetting. Using the musical piece "Für Elise" as a test case, they found that knowledge acquired through text descriptions is forgotten more readily than knowledge acquired through audio input, even under identical adaptation pressures. This phenomenon, termed pathway-dependent forgetting, was observed across various audio-language models and was robust to different experimental controls, suggesting that the input representation, rather than architectural depth, is a key factor.
