The provision of a highly secure service is by far the most important responsibility of any cloud computing network. Users are able to entrust cloud data centers with their most sensitive data and computing operations since this phase in the cloud computing process is built on trust between users and cloud services providers. However, with the proliferation of collaborative cloud computing comes a significant obstacle in the form of the question of how to provide instant responses to a large number of client enquiries. In order to provide highly dependable services in a timely manner, tens of millions of customers' expectations must be met, and the underlying service platform must be able to efficiently and swiftly fulfil tens of thousands of service requirements automatically. The basic need for setting up a reliable and interactive cloud infrastructure is to use trust systems that are not only lightweight and speedy but also high-speed and low-cost. This paper proposes a novel and concurrent computing architecture for confidence that is centered on large data processing, and it is intended for usage in a world that relies on secure cloud infrastructure. Second, it is suggested that a distributed and scalable perceptive infrastructure for the operation of large virtual machines be built using remote monitoring agents. This infrastructure would be built using remote monitoring agents. After that, a technique for the calculation of confidence that is adaptable, lightweight, and parallel is provided for big, controlled data sets. According to what is currently known, this article is the first one to employ a disruptive and parallel computing method together with a significantly accelerated rate of confidence measurement. This enables the confidence calculation framework to be suitable for application in a large-scale cloud setting. The intended system's efficiency and effectiveness were evaluated based on the outcomes of the success review and experimental research. ©

A Low-Rank Matching Attention Based Cross-Modal Feature Fusion Method for Conversational Emotion Recognition

Conversational emotion recognition (CER) is an important research topic in human-computer interactions. Although recent advancements in transformer-based cross-modal fusion methods have shown promise in CER tasks, they tend to overlook the crucial intra-modal and inter-modal emotional interaction or suffer from high computational complexity. To address this, we introduce a novel and lightweight cross-modal feature fusion method called Low-Rank Matching Attention Method (LMAM). LMAM effectively captures contextual emotional semantic information in conversations while mitigating the quadratic complexity issue caused by the self-attention mechanism. Specifically, by setting a matching weight and calculating inter-modal features attention scores row by row, LMAM requires only one-third of the parameters of self-attention methods. We also employ the low-rank decomposition method on the weights to further reduce the number of parameters in LMAM. As a result, LMAM offers a lightweight model while avoiding overfitting problems caused by a large number of parameters. Moreover, LMAM is able to fully exploit the intra-modal emotional contextual information within each modality and integrates complementary emotional semantic information across modalities by computing and fusing similarities of intra-modal and inter-modal features simultaneously. Experimental results verify the superiority of LMAM compared with other popular cross-modal fusion methods on the premise of being more lightweight. Also, LMAM can be embedded into any existing state-of-the-art CER methods in a plug-and-play manner, and can be applied to other multi-modal recognition tasks, e.g., session recommendation and humour detection, demonstrating its remarkable generalization ability. © 2024 IEEE.

Fractional Linear Matroid Matching Is in Quasi-NC

The matching and linear matroid intersection problems are solvable in quasi-NC, meaning that there exist deterministic algorithms that run in polylogarithmic time and use quasi-polynomially many parallel processors. However, such a parallel algorithm is unknown for linear matroid matching, which generalizes both of these problems. In this work, we propose a quasi-NC algorithm for fractional linear matroid matching, which is a relaxation of linear matroid matching and commonly generalizes fractional matching and linear matroid intersection. Our algorithm builds upon the connection of fractional matroid matching to non-commutative Edmonds' problem recently revealed by Oki and Soma (2023). As a corollary, we also solve black-box non-commutative Edmonds' problem with rank-two skew-symmetric coefficients. © Rohit Gurjar, Taihei Oki, and Roshan Raj;licensed under Creative Commons License CC-BY 4.0.

Image authentication is one technique that provides integrity protection for digital images, making them sensitive to any slight modification. Recently, the detectability of absolute moment block truncation coding (AMBTC) compressed images has been attracting more attention due to its integrity authentication concerns. Thus, this paper proposes an effective N-variant AMBTC based image authentication scheme for AMBTC compressed images. First, a novel AMBTC compression code is derived using a variant AMBTC technique that can provide a better quality of compressed images. Then, each AMBTC compression code is further eliminated into a version requiring fewer bits using the proposed N-variant AMBTC technique, and those vacated N-bits are used to conceal authentication codes, which is generated by hashing the AMBTC compression code and location information. Experimental results confirm that the proposed scheme has superior stability and accuracy in tampering detection while providing better visual quality of the watermarked image. © 2023, The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature.

Focusing on the issue where traditional fault diagnosis methods cannot effectively utilize the textual records of railway equipment faults and heavily rely on experts' experience, a knowledge graph-based fault analysis method for railway operation equipment is proposed. By designing preprocessing rules to process the text corpus to be annotated, and combining the attention mechanism (ATT) and bi-directional gated recurrent neural network (BiGRU) to complete the knowledge extraction, the knowledge graph of railway operation equipment faults is constructed. On this basis, a cause recommendation strategy combining query and reasoning is designed, which can give reasonable fault analysis suggestions based on the faults that have occurred. This research utilizes the dataset sourced from a railway administration, examines the effectiveness of the knowledge extraction method through experiments, and analyzes the feasibility of utilizing the constructed knowledge graph to assist in fault analysis through cause recommendation. © 2024 IEEE.
