The work of <cite>Conneau et al. (2018)</cite> , which we focus on here, also makes several implicit assumptions that may or may not be necessary to achieve such isomorphism, and which may or may not scale to low-resource languages. <cite>The algorithms</cite> are not intended to be limited to learning scenarios where these assumptions hold, but since they do in the reported experiments, it is important to see to what extent these assumptions are necessary for <cite>the algorithms</cite> to produce useful embeddings or dictionaries.
