Generative artificial intelligence (AI) has recently gained significant atten-tion, particularly with the rapid development and increased accessibility oflarge language models (LLMs), such as OpenAI’s Chat-GPT1 and Google’sPaLM2. LLMs are AI tools d...

在金融科技快速发展的背景下，厘清数字化赋能商业银行功能转型的影响及其 异质性，对于准确把握并推动不同类型银行数字化转型具有重要意义。本文基于银行流动性 创造和风险承担的功能视角，通过手动整理、文本挖掘等方式收集海量微观数据，构建中国 商业银行数字化转型指数，在此基础上，实证分析数字化转型对银行功能的影响及其可能存 在的“马太效应”，并进一步考察外部数字化与内部数字化之间的关系。结果表明：银行数字 化转型有助于促进银行流动性创造并降低风险承担水平。机制分析表明，数字化转型主要通 过提高银行经...

Generative Artificial Intelligence (AI) has rapidly advanced the field of computer vision by enabling machines to create and interpret visual data with unprecedented sophistication. This transformation builds upon a foundation of generative models...

Abstract—Recent breakthroughs in autonomous driving have revolutionized the way vehicles perceive and interact with theirsurroundings. In particular, world models have emerged as a linchpin technology, offering high-fidelity representations of the...

2024年11月，中国财政部代 表中国政府在沙特首都利雅得成 功发行了20亿美元主权债券。此 次发行的债券将在香港联合交易 所和纳斯达克迪拜交易所上市。 此次发行的债券包括三年期12.5 亿美元，发行利率为4.284%； 五年期7.5亿美元，发行利率为 4.340%。发行利率较同期限美国 国债利差分别仅为一个基点和三 个基点，创下了美元债券市场最 低利差纪录。此次发行的总认购 金额达397.3亿美元，是发行金额 的19.9倍；其中五年期认购倍数 达27.1倍，也是近年来全球主权 债券发行的...

This tutorial provides an in-depth guide on inference-time guidance and alignment methodsfor optimizing downstream reward functions in diffusion models. While diffusion models arerenowned for their generative modeling capabilities, practical appli...

Similar to text and visual synthesis, AI-based speech synthesis methods have made enormous progress in recent years, which is mainly due to the so-called “end-to-end learning” paradigm: Here, text analysis, acoustic modelling and audio synthesis a...

The semiconductor industry had a robust 2024, with expected double-digit (19%) growth, and sales of US$627 billion for the year. But that’seven better than the earlier forecast of US$611 billion. And 2025 could be even better, with predicted sales...

Solar capacity is booming around the world, both utility scale and residential applications, and is often accompanied by energy storage whose costs are declining as well. Yet after $9 trillion globally over the last decade spent on wind, solar, el...

Abstract—Large Language Models (LLMs) have transformed the natural language processing landscape and brought to life diverse applications. Pretraining on vast web-scale data has laid the foundation for these models, yet the research community is n...

This essay examines South Korea’s response to the volatile geopolitical and economic landscape in Northeast Asia, highlighting its multi-track free trade agreement (FTA) strategy and its economic statecraft amid the rising techno-hegemonic competi...

女性几乎占尼泊尔年轻劳动年龄人口的近一半,但她们参与劳动力的可能性低于男性。当她们就业时，她们主要在非正式或维持生计的工作中工作，这些工作以缺乏社会保护和相对于男性的低工资为特征。这些结果背后的一个关键因素是，育儿责任主要落在女性身上，她们在工作中、在家庭中或更广泛的社会层面上得到的支持很少或不足。需要一个全面包容的父母福利框架,包括所有父母(男性和女性)，以及所有工作个人，无论其就业类型(正式、非正式、兼职)，以弥合育儿责任与女性就业之间的差距。在发展经济体中设计和实施此类福利时，必须意...

大型语言模型的快速发展已彻底革新了软件开发中的代码智能。然而，主要依赖闭源模型限制 了广泛的研究与开发。为解决这一问题，我们推出了DeepSeek-Coder系列开源代码模型，其 规模从13亿到330亿不等，并从2万亿个标记中从头开始训练。这些模型预先在高质量的项目 级代码语料库上进行训练，并采用16K窗口的填空任务来增强代码生成和填补。我们的广泛评 估表明，DeepSeek-Coder不仅在多个基准测试中实现了开源代码模型的最佳性能，还超越了 现有的闭源模型如Codex和GPT-3.5。...

This study employs a cluster randomized controlled trial and administrative health center data to investigate the effects of authorizing community health workers to deliver a new generation of contraceptive injections directly to women during rout...

Following the gains from variety literature, this paper estimates the welfare impact of growth of the variety of imported goods in 28 countries in East Africa and East Asia and compares the results. While estimating the gains from variety, the ela...

We use bilateral cross-border bank claims by nationality to assess the effects of geopolitics on cross-border bank flows. We show that a rise in geopolitical tensions between countries — disagreements in UN voting, broad sanctions, or sentiments c...

The incidence of currency counterfeiting and the possible total stock of counterfeits in circulation are popular topics of speculation and discussion in the press and are of substantial practical interest to the Federal Reserve, the U.S. Treasury ...

Analysis of market liquidity often focuses on measures of the current cost of trading. However, investors and policy-makers also care about what would happen to liquidity in the event of an adverse shock. If liquidity were to deteriorate rapidly a...
