Determining usefulness of machine learning in materials discovery using simulated research landscapes.

When existing experimental data are combined with machine learning (ML) to predict the performance of new materials, the data acquisition bias determines ML usefulness and the prediction accuracy. In this context, the following two conditions are highly common: (i) constructing new unbiased data sets is too expensive and the global knowledge effectively does not change by performing a limited number of novel measurements; (ii) the performance of the material depends on a limited number of physical parameters, much smaller than the range of variables that can be changed, albeit such parameters are unknown or not measurable. To determine the usefulness of ML under these conditions, we introduce the concept of simulated research landscapes, which describe how datasets of arbitrary complexity evolve over time. Simulated research landscapes allow us to use different discovery strategies to compare standard materials exploration with ML-guided explorations, i.e. we can measure quantitatively the benefit of using a specific ML model. We show that there is a window of opportunity to obtain a significant benefit from ML-guided strategies. The adoption of ML can take place too soon (not enough information to find patterns) or too late (dense datasets only allow for negligible ML benefit), and the adoption of ML can even slow down the discovery process in some cases. We offer a qualitative guide on when ML can accelerate the discovery of new best-performing materials in a field under specific conditions. The answer in each case depends on factors like data dimensionality, corrugation and data collection strategy. We consider how these factors may affect the ML prediction capabilities and discuss some general trends.

Backlash in global health and the end of AIDS' exceptionalism in Brazil, 2007-2019.

Glob Public Health 2021 Mar 9:1-12. Epub 2021 Mar 9.

Casa de Oswaldo Cruz, Fiocruz, Rio de Janeiro, Brazil.

This paper examines the decline of the AIDS Programme in Brazil, the Latin American country most affected by the epidemic, with emphasis in the second decade of the twenty-first century. For many years, Brazil served as a model in Global Health due to a comprehensive preventive policy, a partnership between the government and health activists and the support of life-saving drugs as public goods rather than commodities. The regression of AIDS policies in Brazil interacted with developments in the United States as well as with multilateral agencies like UNAIDS that emphasised biomedicalisation in the response to the disease where broad human-rights programmes and alliance with activists were not priorities. International programmes like the 'Ending AIDS' campaign indirectly undermined the exceptional status AIDS enjoyed since the late 1980s. The backlash in Brazilian policies to fight AIDS was a result of the fragmentation of the left and the empowerment of radical conservative authoritarian and religious forces. The result was the breakdown of the long-held belief that successful anti-AIDS disease programmes could simultaneously help control the disease and build better healthcare systems and ultimately prompted the end of the special place AIDS' policy had in Brazil.
