在过去十年中，我们目睹了深度学习的兴起，以占据人工智能领域。人工神经网络的进步与具有大的内存容量大的硬件加速器的相应进步，以及大型数据集的可用性，使能研究人员和从业者能够培训和部署复杂的神经网络模型，这些模型在几个方面实现了最先进的性能跨越计算机视觉，自然语言处理和加强学习的领域。然而，由于这些神经网络变得更大，更复杂，更广泛地使用，目前深度学习模型的基本问题变得更加明显。已知最先进的深度学习模型遭受稳健性不良，无法适应新的任务设置的问题，以要求刚性和不灵活的配置假设。来自集体智能的想法，特别是来自复杂系统，如自组织，紧急行为，群优化和蜂窝系统的复杂系统的概念倾向于产生鲁棒，适应性，并且对环境配置具有较小的刚性假设的解决方案。因此，很自然地看到这些想法纳入更新的深度学习方法。在这篇综述中，我们将提供神经网络研究的历史背景，即神经网络研究的复杂系统的参与，并突出了现代深度学习研究中的几个活跃区域，这些研究融合了集体智能的原则，以推进其当前能力。为了促进双向思想流动，我们还讨论了利用现代深度学习模型的工作，以帮助推进复杂的系统研究。我们希望这次审查可以作为复杂系统和深度学习社区之间的桥梁，以促进思想的交叉授粉和促进跨学科的新合作。

Recent progress in artificial intelligence (AI) has renewed interest in building systems that learn and think like people. Many advances have come from using deep neural networks trained end-to-end in tasks such as object recognition, video games, and board games, achieving performance that equals or even beats humans in some respects. Despite their biological inspiration and performance achievements, these systems differ from human intelligence in crucial ways. We review progress in cognitive science suggesting that truly human-like learning and thinking machines will have to reach beyond current engineering trends in both what they learn, and how they learn it. Specifically, we argue that these machines should (a) build causal models of the world that support explanation and understanding, rather than merely solving pattern recognition problems; (b) ground learning in intuitive theories of physics and psychology, to support and enrich the knowledge that is learned; and (c) harness compositionality and learning-to-learn to rapidly acquire and generalize knowledge to new tasks and situations. We suggest concrete challenges and promising routes towards these goals that can combine the strengths of recent neural network advances with more structured cognitive models.

在流行媒体中，人造代理商的意识出现与同时实现人类或超人水平智力的那些相同的代理之间通常存在联系。在这项工作中，我们探讨了意识和智力之间这种看似直观的联系的有效性和潜在应用。我们通过研究与三种当代意识功能理论相关的认知能力：全球工作空间理论（GWT），信息生成理论（IGT）和注意力模式理论（AST）。我们发现，这三种理论都将有意识的功能专门与人类领域将军智力的某些方面联系起来。有了这个见解，我们转向人工智能领域（AI），发现尽管远未证明一般智能，但许多最先进的深度学习方法已经开始纳入三个功能的关键方面理论。确定了这一趋势后，我们以人类心理时间旅行的激励例子来提出方式，其中三种理论中每种理论的见解都可以合并为一个单一的统一和可实施的模型。鉴于三种功能理论中的每一种都可以通过认知能力来实现这一可能，因此，具有精神时间旅行的人造代理不仅具有比当前方法更大的一般智力，而且还与我们当前对意识功能作用的理解更加一致在人类中，这使其成为AI研究的有希望的近期目标。

近年来，机器学习的巨大进步已经开始对许多科学和技术的许多领域产生重大影响。在本文的文章中，我们探讨了量子技术如何从这项革命中受益。我们在说明性示例中展示了过去几年的科学家如何开始使用机器学习和更广泛的人工智能方法来分析量子测量，估计量子设备的参数，发现新的量子实验设置，协议和反馈策略，以及反馈策略，以及通常改善量子计算，量子通信和量子模拟的各个方面。我们重点介绍了公开挑战和未来的可能性，并在未来十年的一些投机愿景下得出结论。

Deep reinforcement learning is poised to revolutionise the field of AI and represents a step towards building autonomous systems with a higher level understanding of the visual world. Currently, deep learning is enabling reinforcement learning to scale to problems that were previously intractable, such as learning to play video games directly from pixels. Deep reinforcement learning algorithms are also applied to robotics, allowing control policies for robots to be learned directly from camera inputs in the real world. In this survey, we begin with an introduction to the general field of reinforcement learning, then progress to the main streams of value-based and policybased methods. Our survey will cover central algorithms in deep reinforcement learning, including the deep Q-network, trust region policy optimisation, and asynchronous advantage actor-critic. In parallel, we highlight the unique advantages of deep neural networks, focusing on visual understanding via reinforcement learning. To conclude, we describe several current areas of research within the field.

We are currently unable to specify human goals and societal values in a way that reliably directs AI behavior. Law-making and legal interpretation form a computational engine that converts opaque human values into legible directives. "Law Informs Code" is the research agenda capturing complex computational legal processes, and embedding them in AI. Similar to how parties to a legal contract cannot foresee every potential contingency of their future relationship, and legislators cannot predict all the circumstances under which their proposed bills will be applied, we cannot ex ante specify rules that provably direct good AI behavior. Legal theory and practice have developed arrays of tools to address these specification problems. For instance, legal standards allow humans to develop shared understandings and adapt them to novel situations. In contrast to more prosaic uses of the law (e.g., as a deterrent of bad behavior through the threat of sanction), leveraged as an expression of how humans communicate their goals, and what society values, Law Informs Code. We describe how data generated by legal processes (methods of law-making, statutory interpretation, contract drafting, applications of legal standards, legal reasoning, etc.) can facilitate the robust specification of inherently vague human goals. This increases human-AI alignment and the local usefulness of AI. Toward society-AI alignment, we present a framework for understanding law as the applied philosophy of multi-agent alignment. Although law is partly a reflection of historically contingent political power - and thus not a perfect aggregation of citizen preferences - if properly parsed, its distillation offers the most legitimate computational comprehension of societal values available. If law eventually informs powerful AI, engaging in the deliberative political process to improve law takes on even more meaning.

We present a retrospective on the state of Embodied AI research. Our analysis focuses on 13 challenges presented at the Embodied AI Workshop at CVPR. These challenges are grouped into three themes: (1) visual navigation, (2) rearrangement, and (3) embodied vision-and-language. We discuss the dominant datasets within each theme, evaluation metrics for the challenges, and the performance of state-of-the-art models. We highlight commonalities between top approaches to the challenges and identify potential future directions for Embodied AI research.

Imitation learning techniques aim to mimic human behavior in a given task. An agent (a learning machine) is trained to perform a task from demonstrations by learning a mapping between observations and actions. The idea of teaching by imitation has been around for many years, however, the field is gaining attention recently due to advances in computing and sensing as well as rising demand for intelligent applications. The paradigm of learning by imitation is gaining popularity because it facilitates teaching complex tasks with minimal expert knowledge of the tasks. Generic imitation learning methods could potentially reduce the problem of teaching a task to that of providing demonstrations; without the need for explicit programming or designing reward functions specific to the task. Modern sensors are able to collect and transmit high volumes of data rapidly, and processors with high computational power allow fast processing that maps the sensory data to actions in a timely manner. This opens the door for many potential AI applications that require real-time perception and reaction such as humanoid robots, self-driving vehicles, human computer interaction and computer games to name a few. However, specialized algorithms are needed to effectively and robustly learn models as learning by imitation poses its own set of challenges. In this paper, we survey imitation learning methods and present design options in different steps of the learning process. We introduce a background and motivation for the field as well as highlight challenges specific to the imitation problem. Methods for designing and evaluating imitation learning tasks are categorized and reviewed. Special attention is given to learning methods in robotics and games as these domains are the most popular in the literature and provide a wide array of problems and methodologies. We extensively discuss combining imitation learning approaches using different sources and methods, as well as incorporating other motion learning methods to enhance imitation. We also discuss the potential impact on industry, present major applications and highlight current and future research directions.

大型人口系统的分析和控制对研究和工程的各个领域引起了极大的兴趣，从机器人群的流行病学到经济学和金融。一种越来越流行和有效的方法来实现多代理系统中的顺序决策，这是通过多机构增强学习，因为它允许对高度复杂的系统进行自动和无模型的分析。但是，可伸缩性的关键问题使控制和增强学习算法的设计变得复杂，尤其是在具有大量代理的系统中。尽管强化学习在许多情况下都发现了经验成功，但许多代理商的问题很快就变得棘手了，需要特别考虑。在这项调查中，我们将阐明当前的方法，以通过多代理强化学习以及通过诸如平均场游戏，集体智能或复杂的网络理论等研究领域进行仔细理解和分析大型人口系统。这些经典独立的主题领域提供了多种理解或建模大型人口系统的方法，这可能非常适合将来的可拖动MARL算法制定。最后，我们调查了大规模控制的潜在应用领域，并确定了实用系统中学习算法的富有成果的未来应用。我们希望我们的调查可以为理论和应用科学的初级和高级研究人员提供洞察力和未来的方向。

Artificial life is a research field studying what processes and properties define life, based on a multidisciplinary approach spanning the physical, natural and computational sciences. Artificial life aims to foster a comprehensive study of life beyond "life as we know it" and towards "life as it could be", with theoretical, synthetic and empirical models of the fundamental properties of living systems. While still a relatively young field, artificial life has flourished as an environment for researchers with different backgrounds, welcoming ideas and contributions from a wide range of subjects. Hybrid Life is an attempt to bring attention to some of the most recent developments within the artificial life community, rooted in more traditional artificial life studies but looking at new challenges emerging from interactions with other fields. In particular, Hybrid Life focuses on three complementary themes: 1) theories of systems and agents, 2) hybrid augmentation, with augmented architectures combining living and artificial systems, and 3) hybrid interactions among artificial and biological systems. After discussing some of the major sources of inspiration for these themes, we will focus on an overview of the works that appeared in Hybrid Life special sessions, hosted by the annual Artificial Life Conference between 2018 and 2022.

Agent-based modeling (ABM) is a well-established paradigm for simulating complex systems via interactions between constituent entities. Machine learning (ML) refers to approaches whereby statistical algorithms 'learn' from data on their own, without imposing a priori theories of system behavior. Biological systems -- from molecules, to cells, to entire organisms -- consist of vast numbers of entities, governed by complex webs of interactions that span many spatiotemporal scales and exhibit nonlinearity, stochasticity and intricate coupling between entities. The macroscopic properties and collective dynamics of such systems are difficult to capture via continuum modelling and mean-field formalisms. ABM takes a 'bottom-up' approach that obviates these difficulties by enabling one to easily propose and test a set of well-defined 'rules' to be applied to the individual entities (agents) in a system. Evaluating a system and propagating its state over discrete time-steps effectively simulates the system, allowing observables to be computed and system properties to be analyzed. Because the rules that govern an ABM can be difficult to abstract and formulate from experimental data, there is an opportunity to use ML to help infer optimal, system-specific ABM rules. Once such rule-sets are devised, ABM calculations can generate a wealth of data, and ML can be applied there too -- e.g., to probe statistical measures that meaningfully describe a system's stochastic properties. As an example of synergy in the other direction (from ABM to ML), ABM simulations can generate realistic datasets for training ML algorithms (e.g., for regularization, to mitigate overfitting). In these ways, one can envision various synergistic ABM$\rightleftharpoons$ML loops. This review summarizes how ABM and ML have been integrated in contexts that span spatiotemporal scales, from cellular to population-level epidemiology.

深入学习的强化学习（RL）的结合导致了一系列令人印象深刻的壮举，许多相信（深）RL提供了一般能力的代理。然而，RL代理商的成功往往对培训过程中的设计选择非常敏感，这可能需要繁琐和易于易于的手动调整。这使得利用RL对新问题充满挑战，同时也限制了其全部潜力。在许多其他机器学习领域，AutomL已经示出了可以自动化这样的设计选择，并且在应用于RL时也会产生有希望的初始结果。然而，自动化强化学习（AutorL）不仅涉及Automl的标准应用，而且还包括RL独特的额外挑战，其自然地产生了不同的方法。因此，Autorl已成为RL中的一个重要研究领域，提供来自RNA设计的各种应用中的承诺，以便玩游戏等游戏。鉴于RL中考虑的方法和环境的多样性，在不同的子领域进行了大部分研究，从Meta学习到进化。在这项调查中，我们寻求统一自动的领域，我们提供常见的分类法，详细讨论每个区域并对研究人员来说是一个兴趣的开放问题。

The applicability of computational models to the biological world is an active topic of debate. We argue that a useful path forward results from abandoning hard boundaries between categories and adopting an observer-dependent, pragmatic view. Such a view dissolves the contingent dichotomies driven by human cognitive biases (e.g., tendency to oversimplify) and prior technological limitations in favor of a more continuous, gradualist view necessitated by the study of evolution, developmental biology, and intelligent machines. Efforts to re-shape living systems for biomedical or bioengineering purposes require prediction and control of their function at multiple scales. This is challenging for many reasons, one of which is that living systems perform multiple functions in the same place at the same time. We refer to this as "polycomputing" - the ability of the same substrate to simultaneously compute different things. This ability is an important way in which living things are a kind of computer, but not the familiar, linear, deterministic kind; rather, living things are computers in the broad sense of computational materials as reported in the rapidly-growing physical computing literature. We argue that an observer-centered framework for the computations performed by evolved and designed systems will improve the understanding of meso-scale events, as it has already done at quantum and relativistic scales. Here, we review examples of biological and technological polycomputing, and develop the idea that overloading of different functions on the same hardware is an important design principle that helps understand and build both evolved and designed systems. Learning to hack existing polycomputing substrates, as well as evolve and design new ones, will have massive impacts on regenerative medicine, robotics, and computer engineering.

建立一种人类综合人工认知系统，即人工综合情报（AGI），是人工智能（AI）领域的圣杯。此外，实现人工系统实现认知发展的计算模型将是脑和认知科学的优秀参考。本文介绍了一种通过集成元素认知模块来开发认知架构的方法，以实现整个模块的训练。这种方法是基于两个想法：（1）脑激发AI，学习人类脑建筑以构建人类级智能，（2）概率的生成模型（PGM）基础的认知系统，为发展机器人开发认知系统通过整合PGM。发展框架称为全大脑PGM（WB-PGM），其根本地不同于现有的认知架构，因为它可以通过基于感官电机信息的系统不断学习。在这项研究中，我们描述了WB-PGM的基本原理，基于PGM的元素认知模块的当前状态，与人类大脑的关系，对认知模块的整合的方法，以及未来的挑战。我们的研究结果可以作为大脑研究的参考。随着PGMS描述变量之间的明确信息关系，本说明书提供了从计算科学到脑科学的可解释指导。通过提供此类信息，神经科学的研究人员可以向AI和机器人提供的研究人员提供反馈，以及目前模型缺乏对大脑的影响。此外，它可以促进神经认知科学的研究人员以及AI和机器人的合作。

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.

在过去的几十年中，人工智能领域大大进展，灵感来自生物学和神经科学领域的发现。这项工作的想法是由来自传入和横向/内部联系的人脑中皮质区域的自组织过程的过程启发。在这项工作中，我们开发了一个原始的脑激发神经模型，将自组织地图（SOM）和Hebbian学习在重新参与索马里（RESOM）模型中。该框架应用于多模式分类问题。与基于未经监督的学习的现有方法相比，该模型增强了最先进的结果。这项工作还通过在名为SPARP（自配置3D蜂窝自适应平台）的专用FPGA的平台上的模拟结果和硬件执行，演示了模型的分布式和可扩展性。头皮板可以以模块化方式互连，以支持神经模型的结构。这种统一的软件和硬件方法使得能够缩放处理并允许来自多个模态的信息进行动态合并。硬件板上的部署提供了在多个设备上并行执行的性能结果，通过专用串行链路在每个板之间的通信。由于多模式关联，所提出的统一架构，由RESOM模型和头皮硬件平台组成的精度显着提高，与集中式GPU实现相比，延迟和功耗之间的良好折衷。

蒙特卡洛树搜索（MCT）是设计游戏机器人或解决顺序决策问题的强大方法。该方法依赖于平衡探索和开发的智能树搜索。MCT以模拟的形式进行随机抽样，并存储动作的统计数据，以在每个随后的迭代中做出更有教育的选择。然而，该方法已成为组合游戏的最新技术，但是，在更复杂的游戏（例如那些具有较高的分支因素或实时系列的游戏）以及各种实用领域（例如，运输，日程安排或安全性）有效的MCT应用程序通常需要其与问题有关的修改或与其他技术集成。这种特定领域的修改和混合方法是本调查的主要重点。最后一项主要的MCT调查已于2012年发布。自发布以来出现的贡献特别感兴趣。

尽管人工神经网络（ANN）取得了重大进展，但其设计过程仍在臭名昭著，这主要取决于直觉，经验和反复试验。这个依赖人类的过程通常很耗时，容易出现错误。此外，这些模型通常与其训练环境绑定，而没有考虑其周围环境的变化。神经网络的持续适应性和自动化对于部署后模型可访问性的几个领域至关重要（例如，IoT设备，自动驾驶汽车等）。此外，即使是可访问的模型，也需要频繁的维护后部署后，以克服诸如概念/数据漂移之类的问题，这可能是繁琐且限制性的。当前关于自适应ANN的艺术状况仍然是研究的过早领域。然而，一种自动化和持续学习形式的神经体系结构搜索（NAS）最近在深度学习研究领域中获得了越来越多的动力，旨在提供更强大和适应性的ANN开发框架。这项研究是关于汽车和CL之间交集的首次广泛综述，概述了可以促进ANN中充分自动化和终身可塑性的不同方法的研究方向。

The last decade witnessed increasingly rapid progress in self-driving vehicle technology, mainly backed up by advances in the area of deep learning and artificial intelligence. The objective of this paper is to survey the current state-of-the-art on deep learning technologies used in autonomous driving. We start by presenting AI-based self-driving architectures, convolutional and recurrent neural networks, as well as the deep reinforcement learning paradigm. These methodologies form a base for the surveyed driving scene perception, path planning, behavior arbitration and motion control algorithms. We investigate both the modular perception-planning-action pipeline, where each module is built using deep learning methods, as well as End2End systems, which directly map sensory information to steering commands. Additionally, we tackle current challenges encountered in designing AI architectures for autonomous driving, such as their safety, training data sources and computational hardware. The comparison presented in this survey helps to gain insight into the strengths and limitations of deep learning and AI approaches for autonomous driving and assist with design choices. 1
