• Abstract: Continual learning is a subfield of machine learning, which aims to allow machine learning models to continuously learn on new data, by accumulating knowledge without forgetting what was learned in the past. In this work, we take a step back, and ask: "Why should one care about continual learning in the first place?". We set the stage by examining recent continual learning papers published at four major machine learning conferences, and show that memory-constrained settings dominate the field. Then, we discuss five open problems in machine learning, and even though they might seem unrelated to continual learning at first sight, we show that continual learning will inevitably be part of their solution. These problems are model editing, personalization and specialization, on-device learning, faster (re-)training and reinforcement learning. Finally, by comparing the desiderata from these unsolved problems and the current assumptions in continual learning, we highlight and discuss four future directions for continual learning research. We hope that this work offers an interesting perspective on the future of continual learning, while displaying its potential value and the paths we have to pursue in order to make it successful. This work is the result of the many discussions the authors had at the Dagstuhl seminar on Deep Continual Learning, in March 2023.

  Continual learning and machine unlearning are crucial challenges in machine learning, typically addressed separately. We introduce a novel framework that jointly tackles both tasks by leveraging controlled knowledge distillation. Our approach enables efficient learning with minimal forgetting and effective targeted unlearning.

• Prospective Learning: Principled Extrapolation to the Future [45.287871145154135]
  Learning evolve a process which can update decision rules based on past experience such that future performance improves. Traditionally machine learning is often evaluated under the assumption that the future will be identical to the past in distribution or adversarial dynamics. Here we reformulate the learning problem to one that centers around this idea of dynamic futures that are partially learnable. We argue that prospective learning more accurately characterizes many real world problems that (1) currently lack adequate explanations for how natural intelligences solve them.
