There has been much interest in the problem of systematic generalization in recent years (Bahdanau et al., 2019;Bentivogli et al., 2016;Lake et al., 2017a,b;Gershman and Tenenbaum, 2015;McCoy et al., 2019a;Veldhoen and Zuidema, 2017;Soulos et al., 2019;Prasad et al., 2019;Richardson et al., 2019;Johnson et al., 2017, inter alia).
to our approach (testing novel words in familiar combinations), many of these studies probe systematicity by testing familiar words in novel combinations.
