论文摘要
这份白皮书阐明了未来十年(及以后)人工智能领域的研发愿景。它的结局是一个自然和合成感的网络物理生态系统,人类是不可或缺的参与者 - 我们称之为“共享智能”。该愿景以主动推论为前提,即适应行为的表述,可以将其读成智力的物理学,并从自组织的物理学中继承。在这种情况下,我们将智力理解为积累一个感知世界的生成模型的证据的能力 - 也称为自我验证。正式地,这对应于最大化(贝叶斯)模型证据,这是通过在几个尺度上进行信念更新的:即推论,学习和模型选择。在操作上,可以通过(变化)消息传递或信念传播在因子图上实现这种自我评价。至关重要的是,主动推理预示着智能系统的存在命令;即好奇心或不确定性的解决。同样的当务之急,在代理集合中的信念共享,其中每个代理人生成世界模型的某些方面(即因素)提供了共同的理由或参考框架。主动推断在这种信念共享的生态学中起着基本作用,这导致了集体智能的正式描述,这基于共同的叙述和目标。我们还考虑必须开发的各种通信协议,以实现这种智力生态系统,并激发共享的超空间建模语言和交易协议的开发,这是迈向这种生态学的第一和关键。
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 -- 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 -- 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 -- 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 -- and key -- step towards such an ecology.
