  In this paper we will discuss metalearning and how we can go beyond the
current classical learning paradigm. We will first address the importance of
inductive biases in the learning process and what is at stake: the quantities
of data necessary to learn. We will subsequently see the importance of choosing
suitable parameterizations to end up with well-defined learning processes.
Especially since in the context of real-world applications, we face numerous
biases due, e.g., to the specificities of sensors, the heterogeneity of data
sources, the multiplicity of points of view, etc. This will lead us to the idea
of exploiting the structuring of the concepts to be learned in order to
organize the learning process that we published previously. We conclude by
discussing the perspectives around parameter-tying schemes and the emergence of
universal aspects in the models thus learned.
