A hybrid-model optimization algorithm based on the Gaussian process and particle swarm optimization for mixed-variable CNN hyperparameter automatic search Front. Inform. Technol. Electron. Eng. (IF 3.0) Pub Date : 2023-09-07 Han Yan, Chongquan Zhong, Yuhu Wu, Liyong Zhang, Wei Lu
Convolutional neural networks (CNNs) have been developed quickly in many real-world fields. However, CNN’s performance depends heavily on its hyperparameters, while finding suitable hyperparameters for CNNs working in application fields is challenging for three reasons: (1) the problem of mixed-variable encoding for different types of hyperparameters in CNNs, (2) expensive computational costs in evaluating

TPE-H2MWD: an exact thumbnail preserving encryption scheme with hidden Markov model and weighted diffusion Front. Inform. Technol. Electron. Eng. (IF 3.0) Pub Date : 2023-08-30 Xiuli Chai, Xiuhui Chen, Yakun Ma, Fang Zuo, Zhihua Gan, Yushu Zhang
With the substantial increase in image transmission, the demand for image security is increasing. Noise-like images can be obtained by conventional encryption schemes, and although the security of the images can be guaranteed, the noise-like images cannot be directly previewed and retrieved. Based on the rank-then-encipher method, some researchers have designed a three-pixel exact thumbnail preserving

High capacity reversible data hiding in encrypted images based on adaptive quadtree partitioning and MSB prediction Front. Inform. Technol. Electron. Eng. (IF 3.0) Pub Date : 2023-08-30 Kaili Qi, Minqing Zhang, Fuqiang Di, Yongjun Kong
To improve the embedding capacity of reversible data hiding in encrypted images (RDH-EI), a new RDH-EI scheme is proposed based on adaptive quadtree partitioning and most significant bit (MSB) prediction. First, according to the smoothness of the image, the image is partitioned into blocks based on adaptive quadtree partitioning, and then blocks of different sizes are encrypted and scrambled at the

Reversible data hiding using a transformer predictor and an adaptive embedding strategy Front. Inform. Technol. Electron. Eng. (IF 3.0) Pub Date : 2023-08-30 Linna Zhou, Zhigao Lu, Weike You, Xiaofei Fang
In the field of reversible data hiding (RDH), designing a high-precision predictor to reduce the embedding distortion and developing an effective embedding strategy to minimize the distortion caused by embedding information are the two most critical aspects. In this paper, we propose a new RDH method, including a predictor based on a transformer and a novel embedding strategy with multiple embedding

A survey of the pursuit–evasion problem in swarm intelligence Front. Inform. Technol. Electron. Eng. (IF 3.0) Pub Date : 2023-08-30 Zhenxin Mu, Jie Pan, Ziye Zhou, Junzhi Yu, Lu Cao
For complex functions to emerge in artificial systems, it is important to understand the intrinsic mechanisms of biological swarm behaviors in nature. In this paper, we present a comprehensive survey of pursuit–evasion, which is a critical problem in biological groups. First, we review the problem of pursuit–evasion from three different perspectives: game theory, control theory and artificial intelligence
