Query: Online Structured Meta-learning   Learning quickly is of great importance for machine intelligence deployed in
online platforms. With the capability of transferring knowledge from learned
tasks, meta-learning has shown its effectiveness in online scenarios by
continuously updating the model with the learned prior. However, current online
meta-learning algorithms are limited to learn a globally-shared meta-learner,
which may lead to sub-optimal results when the tasks contain heterogeneous
information that are distinct by nature and difficult to share. We overcome
this limitation by proposing an online structured meta-learning (OSML)
framework. Inspired by the knowledge organization of human and hierarchical
feature representation, OSML explicitly disentangles the meta-learner as a
meta-hierarchical graph with different knowledge blocks. When a new task is
encountered, it constructs a meta-knowledge pathway by either utilizing the
most relevant knowledge blocks or exploring new blocks. Through the
meta-knowledge pathway, the model is able to quickly adapt to the new task. In
addition, new knowledge is further incorporated into the selected blocks.
Experiments on three datasets demonstrate the effectiveness and
interpretability of our proposed framework in the context of both homogeneous
and heterogeneous tasks.
