Deep neural networks have demonstrated exceptional performance in extracting task-specific representations from datasets, earning widespread recognition and application. However, the internal representations often reside in abstract, high-dimensional spaces that are unsupervised and difficult to interpret. Additionally, their complex and tightly coupled structures hinder researchers' ability to understand the models effectively. To tackle these challenges, we introduce NeuronExplorer, an analytical framework that employs self-supervised techniques for learning high-dimensional information representations. NeuronExplorer analyzes the high-dimensional representations derived from the basic units, namely neurons, within the neural network, predicting the clusters to which these neurons belong. This process facilitates the ‘community’ of neurons, enhancing interpretability.Moreover, we refine this neuron community structure by assessing the causal effects of intervening in neuron outputs, allowing us to measure the impact on model performance. NeuronExplorer ultimately enables a deeper understanding of the internal information representation within deep neural networks. Comprehensive experiments conducted across multiple models demonstrate that NeuronExplorer effectively mines internal representations, thereby improving model transparency.
深度神经网络在从数据集中提取特定任务表示方面表现出优异的性能,获得了广泛的认可和应用。然而,内部表征通常驻留在抽象的高维空间中,不受监督,难以解释。此外,它们复杂和紧密耦合的结构阻碍了研究人员有效理解模型的能力。为了应对这些挑战,我们引入了NeuronExplorer,这是一个使用自监督技术来学习高维信息表示的分析框架。NeuronExplorer分析来自神经网络中基本单元(即神经元)的高维表示,预测这些神经元所属的簇。这个过程促进了神经元的“社区”,增强了可解释性。此外,我们通过评估干预神经元输出的因果效应来完善这个神经元群落结构,使我们能够测量对模型性能的影响。NeuronExplorer最终能够更深入地理解深度神经网络中的内部信息表示。在多个模型上进行的综合实验表明,NeuronExplorer有效地挖掘了内部表征,从而提高了模型的透明度。

The development of intelligent transportation systems and the advancement of information technology bring new challenges to route planning, as shorter travel time may no longer be the travelers’ only preference for a route, and the preferences may also change over time which is overlooked in most prior work. In this paper, we study a new bi-objective planning problem with both time-dependent travel time and preference. The first objective is to maximize the total preference score and the second one is to minimize the total travel time. For the considered problem, an appropriate bi-objective integer linear model is formulated. Then, an exact $epsilon$-constraint method is proposed for small-sized instances, while a problem specific non-dominated sorting genetic algorithm-II (NSGA-II) is designed to handle large-sized instances. Specifically, novel region-based encoding and decoding methods are introduced to generate a set of solutions. Additionally, a feasibility condition and a repair strategy are incorporated to address cases where a chromosome is infeasible. We evaluate the proposed methods thoroughly based on 120 randomly generated road networks and 3 real-world road networks crawled via the OpenStreetMap platform. Results show that: (i) $epsilon$-constraint method obtains good performance on small-sized road networks; (ii) our problem-specific NSGA-II works well with large-sized road networks in obtaining the high-quality solutions while significantly saving computational time.
智能交通系统的发展和信息技术的进步给路线规划带来了新的挑战,因为较短的出行时间可能不再是旅行者对路线的唯一偏好,而且这种偏好也可能随着时间的推移而变化,这在大多数先前的工作中被忽视。本文研究了一种新的具有时间依赖的出行时间和出行偏好的双目标规划问题。第一个目标是使总偏好得分最大化,第二个目标是使总旅行时间最小化。对于所考虑的问题,建立了一个合适的双目标整数线性模型。然后,针对小型实例提出了一种精确的$epsilon$约束方法,针对大型实例设计了一种针对特定问题的非支配排序遗传算法- ii (NSGA-II)。具体来说,介绍了新的基于区域的编码和解码方法来生成一套解决方案。此外,可行性条件和修复策略被纳入解决染色体不可行的情况。我们基于120个随机生成的道路网络和3个通过OpenStreetMap平台抓取的现实世界道路网络,彻底评估了所提出的方法。结果表明:(i) $epsilon$-约束方法在小型路网上获得了良好的性能;(ii)我们针对特定问题的NSGA-II在处理大型道路网络时,能很好地获得高质量的解决方案,同时大大节省计算时间。

Thanks to higher power quality and performance efficiency, multilevel grid-tied inverters are the right choice for DC-to-AC conversion like the PV systems to the main power grid. However, the complexity of controlling the switching devices and capacitor voltages in these inverters presents significant stability challenges, particularly during grid-tied operation and when dealing with parameter mismatches. This paper proposes an optimized adaptive Active Disturbance Rejection Controller (ADRC) to stabilize the current of the grid-tied PEC9, serving as a multilevel inverter for PV applications. For this purpose, the PV system, connected to PEC9 as a main DC source to be integrated into the grid. The tunable coefficients of the ADRC controller are automatically adjusted using the on-policy reinforcement learning (RL) technique to effectively stabilize the grid-tied PEC9 with a PV inverter. In this approach, a reward function tailored to the inverter requirements guides the RL-agent in determining the optimal policy. Through maximizing the reward signal, the on-policy algorithm generates regulatory signals to adjust control gains accordingly. A laboratory prototype of PEC9 inverter is constructed by implementing OPAL-RT simulator to investigate the feasibility and applicability of suggested adaptive data-driven scheme. The experimental responses of grid-tied PEC9 equipped with the proposed adaptive ADRC demonstrate the effective performance under various operating conditions of grid-tied PV inverters, including change in the system’s references and parameter mismatches.
由于更高的功率质量和性能效率,多级并网逆变器是直流到交流转换的正确选择,就像光伏系统到主电网一样。然而,控制这些逆变器中的开关器件和电容器电压的复杂性对稳定性提出了重大挑战,特别是在并网运行和处理参数不匹配时。本文提出了一种优化的自适应自抗扰控制器(ADRC)来稳定并网PEC9的电流,作为光伏应用中的多电平逆变器。为此,PV系统,连接到PEC9作为一个主要的直流电源被整合到电网中。采用策略强化学习(on-policy reinforcement learning, RL)技术对ADRC控制器的可调系数进行自动调整,从而有效地稳定了带PV逆变器的并网PEC9。在这种方法中,根据逆变器需求定制的奖励函数指导RL-agent确定最优策略。策略上算法通过最大化奖励信号,产生调节信号来相应调整控制增益。利用OPAL-RT仿真器构建了PEC9逆变器的实验室样机,验证了所提出的自适应数据驱动方案的可行性和适用性。安装该自适应自抗扰控制器的并网PEC9的实验响应表明,在并网光伏逆变器的各种运行条件下,包括系统参考参数的变化和参数的不匹配,其性能都是有效的。

In the recent years, researchers made significant progress in electroencephalogram (EEG) classification tasks using deep neural networks, especially in brain-computer interface (BCI) systems. BCI systems rely on EEG signals for effective human-computer interaction, and deep neural networks have shown excellent performance in processing EEG signals. However, backdoor attack have a significant impact on the security of EEG-based BCI systems. In this paper, a novel multi-scale Shapley adaptation pruning (MSAP) method is proposed to solve the security problem caused by backdoor attack. In the proposed MSAP, the multi-scale Shapley segmented mapping method is used to accurately locate the backdoor weights. Subsequently, the cost function is utilized to adaptively prune the backdoor weights to ensure normal classification. Ultimately, the validity of the experiments is verified on the BCI competition public datasets (BCI-III-IVb, BCI-III-IVa, and BCI-IV-1a). The results show that the proposed MSAP method outperforms other pruning methods in defending EEG-based BCI systems against backdoor attack, maintaining a high baseline classification accuracy while reducing the attack success rate.

This paper presents a novel recommendation system designed to effectively suggest products to users by leveraging a neutrosophic fuzzy hypergraph structure, where users are represented as hyperedges and products as hypernodes. The approach incorporates a global partial order of items, derived from frequent pattern analysis, to establish an ordering framework over product recommendations. State vectors representing users are extracted and refined through a Graph Convolutional Neural Network (GCN), which captures the intricate relationships within the graph. Using a Deep Q Network (DQN)-based reinforcement learning model with indeterminacy-driven exploration-exploitation, the system learns optimal recommendation strategies from the feature representations of the neutrosophic fuzzy hypergraph. Reward signals are calculated by assessing how closely a new recommendation aligns with the partial ordering, as well as by using fuzzy rules generated from a domain-specific expert system. The recommendations are explained using paths extracted from the hypergraph. Our experimental evaluation on real-world datasets demonstrates that the proposed system outperforms state-of-the-art recommendation approaches in terms of Normalized Cumulative Discounted Gain(NDCG) and precision, indicating its strong suitability for practical applications in complex recommendation environments.
本文提出了一种新的推荐系统,通过利用中性模糊超图结构有效地向用户推荐产品,其中用户表示为超边缘,产品表示为超节点。该方法结合了从频繁模式分析中派生出来的项目的全局部分顺序,以建立产品推荐的排序框架。通过图形卷积神经网络(GCN)提取和细化表示用户的状态向量,该网络捕获图中复杂的关系。系统采用基于深度Q网络(Deep Q Network, DQN)的不确定性驱动探索开发强化学习模型,从嗜中性模糊超图的特征表示中学习最优推荐策略。奖励信号是通过评估新推荐与部分排序的接近程度以及使用由特定领域专家系统生成的模糊规则来计算的。使用从超图中提取的路径来解释这些建议。我们在真实世界数据集上的实验评估表明,所提出的系统在归一化累积贴现增益(NDCG)和精度方面优于最先进的推荐方法,表明其在复杂推荐环境中的实际应用具有很强的适用性。
