New theory defines and measures "forgetting" in machine learning algorithms

Researchers have proposed a new theoretical framework to understand and quantify "forgetting" in machine learning algorithms. This theory defines forgetting as a lack of self-consistency in a learner's predictive distribution, leading to a loss of predictive information. The proposed measure can be applied across various machine learning tasks, including classification, regression, generative modeling, and reinforcement learning. Experiments across these domains indicate that forgetting is a pervasive issue in deep learning, impacting learning efficiency. AI

IMPACT This research could lead to the development of more robust learning algorithms that retain knowledge more effectively, improving efficiency across various AI applications.

    Forgetting is Everywhere

    arXiv:2511.04666v4 Announce Type: replace-cross Abstract: A fundamental challenge in developing general learning algorithms is their tendency to forget past knowledge as they adapt to new data. Addressing this problem requires a principled understanding of forgetting. Yet, despit…
