Abstract

Machine learning tools are becoming increasingly powerful and widely used. Unfortunately membership attacks, which seek to uncover information from data sets used in machine learning, have the potential to limit data sharing. In this paper we consider an approach to increase the privacy protection of data sets, as applied to face recognition. Using an auxiliary face recognition model, we build on the StyleGAN generative adversarial network and feed it with latent codes combining two distinct sub-codes, one encoding visual identity factors, and, the other, non-identity factors. By independently varying these vectors during image generation, we create a synthetic data set of fictitious face identities. We use this data set to train a face recognition model. The model performance degrades in comparison to the state-of-the-art of face verification. When tested with a simple membership attack our model provides good privacy protection, however the model performance degrades in comparison to the state-of-the-art of face verification. We find that the addition of a small amount of private data greatly improves the performance of our model, which highlights the limitations of using synthetic data to train machine learning models.

49. Migration and remittances in island microstates: a comparative perspective on the South Pacific and the Caribbean

Abstract

For several decades there has been extensive migration from the small island states of the South Pacific and the eastern Caribbean to metropolitan countries, resulting in absolute population decline in some states and new social, economic and political relationships between these island regions and distant worlds. Early research on the consequences for island development of return migration and remittances dwelt upon the unproductive nature of expenditures and the various problems return migration and remittances cause. Questioning this view, a new conceptualization of the influences of migration, circulation and remittances on recipient families, communities and societies in the island states of the South Pacific and the Caribbean is presented. Regional similarities and differences are recognized, yet commonalities of island microstates' experiences emerge. Remittances are a very significant private transfer of capital and return migrants represent people endowed with human capital, capable of enriching the social and cultural capital stocks of their island communities. In both insular regions, the consolidation of transnational linkages emphasizes the significance of diaspora relations for migrant households at home and abroad and offers some prospects for sustainable development, beyond those offered solely by domestic economic opportunities.
