In September of 2023, the paradigm of Open Access publishing – #SciELO – celebrated its 25-year jubilee, naturally with an Open Access and Open Science themed conference. The link below points to a report, just published, on the session about technologies that enable accessibility.

In September 2023, prominent voices in Open Science and FAIR Data gathered in São Paulo, Brazil to celebrate the 25th anniversary of the Scientific Electronic Library Online (SciELO). Presentations and workshops were held that reviewed progress in th

Just as true in Europe, including unfortunately all the sad bits.

GemNet: Menu-Based, Strategy-Proof Multi-Bidder Auctions Through Deep Learning
Differentiable economics uses deep learning for automated mechanism design. Despite strong progress, it has remained an open problem to learn multi-bidder, general, and fully strategy-proof (SP) auctions. We introduce GEneral Menu-based NETwork (GemNet), which significantly extends the menu-based approach of RochetNet [Dütting et al., 2023] to the multi-bidder setting. The challenge in achieving SP is to learn bidder-independent menus that are feasible, so that the optimal menu choices for eac…

W-kernel and essential subspace for frequencist evaluation of Bayesian estimators
The posterior covariance matrix W defined by the log-likelihood of each observation plays important roles both in the sensitivity analysis and frequencist evaluation of the Bayesian estimators. This study is focused on the matrix W and its principal space; we term the latter as an essential subspace. A key tool for treating frequencist properties is the recently proposed Bayesian infinitesimal jackknife approximation (Giordano and Broderick (2023)). The matrix W can be interpreted as a reproduc…
