The Quality of Death: Ranking End-of-Life Care Across the World

As the proportion of the world's population grows disproportionately older, the need for end-of-life services will only increase. This paper ranks 40 countries in terms of the quality and availability of end-of-life care. For this paper, the author also conducted in-depth interviews with over 20 experts on the subject from across the world -- including palliative care specialists, physicians, healthcare economists and sociologists -- and reviewed existing research on the topic

Entrepreneurial profile of the UK in the light of the global entrepreneurship and development index

In this research summary, we provide a novel look into the entrepreneurial profile of the UK in an international context. We use a new method – the Global Entrepreneurship and Development Index GEDI [1] – to identify the entrepreneurial strengths and weaknesses of the UK economy, as well as to identify potential bottlenecks that hold back the performance of the UK relative to other advanced economies. We begin by providing an overview of the main findings

Reinforced Video Captioning with Entailment Rewards

Sequence-to-sequence models have shown promising improvements on the temporal task of video captioning, but they optimize word-level cross-entropy loss during training. First, using policy gradient and mixed-loss methods for reinforcement learning, we directly optimize sentence-level task-based metrics (as rewards), achieving significant improvements over the baseline, based on both automatic metrics and human evaluation on multiple datasets. Next, we propose a novel entailment-enhanced reward (CIDEnt) that corrects phrase-matching based metrics (such as CIDEr) to only allow for logically-implied partial matches and avoid contradictions, achieving further significant improvements over the CIDEr-reward model. Overall, our CIDEnt-reward model achieves the new state-of-the-art on the MSR-VTT dataset.Comment: EMNLP 2017 (9 pages
