知识图(kg)完成是一项重要任务,它极大地使许多领域的知识发现受益(例如生物医学研究)。近年来,学习kg嵌入以执行此任务的嵌入引起了很大的关注。尽管KG嵌入方法成功,但它们主要使用负抽样,从而增加了计算复杂性以及由于封闭的世界假设而引起的偏见预测。为了克服这些局限性,我们提出了\ textbf {kg-nsf},这是一个基于嵌入向量的互相关矩阵学习kg嵌入的无负抽样框架。结果表明,所提出的方法在收敛速度更快的同时,将可比较的链接预测性能与基于阴性采样的方法达到了可比性的预测性能。

This white paper lays out a vision of research and development in the field of artificial intelligence for the next decade (and beyond). Its denouement is a cyber-physical ecosystem of natural and synthetic sense-making, in which humans are integral participants$\unicode{x2014}$what we call ''shared intelligence''. This vision is premised on active inference, a formulation of adaptive behavior that can be read as a physics of intelligence, and which inherits from the physics of self-organization. In this context, we understand intelligence as the capacity to accumulate evidence for a generative model of one's sensed world$\unicode{x2014}$also known as self-evidencing. Formally, this corresponds to maximizing (Bayesian) model evidence, via belief updating over several scales: i.e., inference, learning, and model selection. Operationally, this self-evidencing can be realized via (variational) message passing or belief propagation on a factor graph. Crucially, active inference foregrounds an existential imperative of intelligent systems; namely, curiosity or the resolution of uncertainty. This same imperative underwrites belief sharing in ensembles of agents, in which certain aspects (i.e., factors) of each agent's generative world model provide a common ground or frame of reference. Active inference plays a foundational role in this ecology of belief sharing$\unicode{x2014}$leading to a formal account of collective intelligence that rests on shared narratives and goals. We also consider the kinds of communication protocols that must be developed to enable such an ecosystem of intelligences and motivate the development of a shared hyper-spatial modeling language and transaction protocol, as a first$\unicode{x2014}$and key$\unicode{x2014}$step towards such an ecology.
