Different from previous works, we propose a reduced-order dynamic observer-based event-triggered quantized control method under a relaxed Lipschitz condition and output injection attack, which effectively reduces computational burden and communication resource usage. First, a novel reduced-order dynamic gain observer estimates unmeasured states under injection attacks. Subsequently, to guarantee that each subsystem's output satisfies the prescribed performance requirements, a barrier-function-based tracking error mapping approach is proposed. Then, an adaptive fuzzy control scheme incorporating decentralized event-triggered output feedback and input quantization is developed using the backstepping technique, thereby optimizing energy efficiency in signal transmission. Next, Lyapunov analysis proves that all closed-loop signals remain bounded with Zeno behavior excluded. Finally, simulations validate the theoretical results under various attack scenarios.</p>","PeriodicalId":13112,"journal":{"name":"IEEE Transactions on Cybernetics","volume":"PP ","pages":""},"PeriodicalIF":11.3,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148840077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional approaches attempt to infer human goals from actions to guide AI policies. However, this behavior-level alignment faces an inherent challenge: the ambiguous mapping between goals and actions, as a single action might serve multiple possible goals, while different actions could achieve the same goal. To overcome these limitations, we propose neural value alignment (NVA), a unifying perspective that leverages key variables in human reinforcement learning (RL): reward prediction error (RPE) and state prediction error (SPE). RPE captures outcome discrepancies, refining AI goal inference, while SPE reflects state transition misalignment, shaping AI actions. Using a novel task paradigm that dissociated RPE and SPE, combined with electroencephalography (EEG) recordings, we demonstrated cortical decodability of RPE, SPE, and their co-occurrence, robustly across contexts. Simulations showed that RPE-SPE synergy accelerated value alignment, even under imperfect decoding. This study bridges RL and human-AI interaction, showing that RPE-SPE synergy enables flexible and human-compatible artificial systems operating under goal-action ambiguity.</p>","PeriodicalId":13112,"journal":{"name":"IEEE Transactions on Cybernetics","volume":"PP ","pages":""},"PeriodicalIF":11.3,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148812692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A multiobjective attack model is proposed under the energy constraint, which comprehensively utilizes available innovations from both reliable and suspicious sensors to disrupt the state estimation performance with the assurance of stealthiness. By deriving the recursion of the error covariance, the optimization objective is formulated as a tradeoff between the terminal and average estimation errors to accommodate different scenarios. The corresponding stealthiness conditions are further analyzed based on an analysis of the statistical characteristics of coupled innovations. Then, according to the properties of orthogonal matrices and the Lagrange multiplier method, closed-form solutions for the optimal attack matrices are derived, which avoid addressing the semidefinite programming problem. Moreover, the optimal scheduling is solved via 0-1 programming after parameter separation. Finally, numerical simulations are provided to validate the results.</p>","PeriodicalId":13112,"journal":{"name":"IEEE Transactions on Cybernetics","volume":"PP ","pages":""},"PeriodicalIF":11.3,"publicationDate":"2026-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148792415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
