Understanding Risk Extrapolation (REx) and when it finds Invariant Relationships
No full textGeneralizing models for new unknown datasets is a common problem in machine learning. Algorithms that perform well for test instances with the same distribution as their training dataset often perform severely on new datasets with a different distribution. This problem is caused by distributional shifts between the training of the model and applying that model to a test domain. This paper addresses whether and in what situations Risk Extrapolation (REx) can tackle this problem of Out-Of-Distribution generalization by exploiting invariant relationships. These relationships are based on features that are invariant across all domains. By learning these relationships, REx aims to learn the concept of the problem we are trying to solve. We show in what situations REx can learn these invariant relationships and when it does not. We translate the definition of an invariant relationship into a homoscedastic synthetic dataset with either covariate, confounded, anti-causal, or hybrid shift. We expose REx to experiments in sample complexity, the number of training domains, and the training domain distance. We show that REx performs better for invariant prediction in situations with larger sample sizes and training domain distance and that if these criteria are met, REx performs equivalently in all four distributional shifts. We also compare REx to Invariant- and Empirical Risk Minimization and show that; REx is less sensitive and thus robust to the shifting of the average distributional variance in the training domains; REx asymptotically out-performs the methods in the more complex distributional shifts.https://gitlab.com/hofland.jeroen/rex-distributional-shift CodeCSE3000 Research ProjectComputer Science and Engineerin

Positioning Patronage: Lanyer's Salve Deus Rex Judæorum and the Countess of Cumberland in Time and Place
No full textThis article places the composition and publication of Aemilia Lanyer's Salve Deus Rex Judæorum within the context of particular periods in the life of Margaret Russell, Countess of Cumberland and her daughter, Anne Clifford, Countess of Dorset. Lanyer's use of mirroring, shared discourse, possible worlds and reconstruction of memory all relate to these periods and were designed to engage the interest of Russell and Clifford. Through the identification of the period of the women's stay in Cookham in 1604, Lanyer's poetic strategies – directly appealing to Russell – can be identified. Lanyer's decision to publish her verse collection in 1610 was also influenced by events in the lives of Russell and Clifford, thus providing insight into Lanyer's canny understanding of patronage in the period
