On the Turing Completeness of Modern Neural Network Architectures
Jorge Pérez, Javier Marinković, Pablo Barceló. ICLR 2019 Conference. https://openreview.net/pdf?id=HyGBdo0qFm

Alternatives to recurrent neural networks, in particular, architectures based on attention or convolutions, have been gaining momentum for processing input sequences. In spite of their relevance, the computational properties of these alternatives have not yet been fully explored. We study the computational power of two of the most paradigmatic architectures exemplifying these mechanisms: the Transformer (Vaswani et al., 2017) and the Neural GPU (Kaiser & Sutskever, 2016). We show both models to be Turing complete exclusively based on their capacity to compute and access internal dense representations of the data. In particular, neither the Transformer nor the Neural GPU requires access to an external memory to become Turing complete. Our study also reveals some minimal sets of elements needed to obtain these completeness results.

Territorial sovereignty and the end of inter-cultural diplomacy along the “Southern frontier”
Carsten-Andreas Schulz. European Journal of International Relations. https://doi.org/10.1177/1354066118814890

European politics at the turn of the 19th century saw a dramatic reduction in the number and diversity of polities as the territorial nation-state emerged as the dominant form of political organization. The transformation had a profound impact on the periphery. The study examines how embracing the principle of territoriality transformed relations between settler societies and indigenous peoples in South America. As this shift coincided with independence from Spain, Creole elites rapidly dismantled the remnants of imperial heteronomy, ending centuries of inter-cultural diplomacy. The study illustrates this shift in the case of the “Southern frontier,” where Spain had maintained a practice of treaty making with the Mapuche people since the mid-17th century. This long-standing practice broke down shortly after Chile gained independence in 1818. What followed was a policy of coercive assimilation through military conquest and forced displacement — a policy that settler societies implemented elsewhere in the 19th century. In contrast to explanations that emphasize the spread of capitalist agriculture and racist ideologies, this study argues that territoriality spelled the end of inter-cultural diplomacy along the “Southern frontier.”
