Query: General supervised learning as change propagation with delta lenses   Delta lenses are an established mathematical framework for modelling and
designing bidirectional model transformations. Following the recent
observations by Fong et al, the paper extends the delta lens framework with a a
new ingredient: learning over a parameterized space of model transformations
seen as functors. We define a notion of an asymmetric learning delta lens with
amendment (ala-lens), and show how ala-lenses can be organized into a symmetric
monoidal (sm) category. We also show that sequential and parallel composition
of well-behaved ala-lenses are also well-behaved so that well-behaved
ala-lenses constitute a full sm-subcategory of ala-lenses.
