BERT-PhishFinder: A Robust Model for Accurate Phishing URL Detection with Optimized DistilBERT

IEEE Transactions on Dependable and Secure Computing 2025年

Phishing URL detection has become a critical challenge in cybersecurity, with existing methods often struggling to maintain high accuracy while generalizing across diverse datasets. In this paper, we introduce BERT-PhishFinder, a novel and efficient transformer-based model designed to tackle this problem. While most traditional approaches rely heavily on lexical features or complex convolutional architectures, BERT-PhishFinder leverages the power of DistilBERT, a lightweight yet highly effective transformer, to capture rich contextual representations of URL sequences. To enhance the model's robustness and reduce overfitting, we strategically incorporate SpatialDropout1D in the embedding layers, along with global average pooling and global max pooling techniques to extract both comprehensive and key discriminative features. The pooled representations are thoughtfully concatenated to form a comprehensive feature representation. Through this carefully crafted design, our model adopts ensemble learning, as it undergoes multiple parallel dense layers, each with distinct parameters and dropout regularization. This facilitates learning diverse patterns and features from the input URL sequence, culminating in exceptional phishing URL detection performance. Extensive evaluations against conventional deep learning algorithms, transformer models (XLNet, RoBERTa, ALBERT), and other existing methods on five benchmark datasets show that BERT-PhishFinder not only achieves the state of-the-art real phishing URL detection but also accomplishes this with reduced label dependency. © 2004-2012 IEEE.

CRLNet: Cascaded Resolution learning Network for Natural Scenes Segmentation

The natural environment presents a multitude of scenes with diverse content, posing challenges for satisfactory segmentation results using existing segmentation networks. In response, we propose a Cascaded Resolution learning Network (CRLNet) to enhance segmentation performance through global textual embedding and multi-resolution feature learning. The CRLNet constructs a multi-path segmentation system that integrates multi-resolution feature data from different paths, thereby progressively enhancing local feature learning. Two key modules, the Partition-Fusion Channel Attention Module (PFCAM) and the Features learning Module (FLM), are pivotal components of CRLNet. The PFCAM serves as a computationally efficient channel attention module to mitigate segmentation confusion stemming from similar objects. Meanwhile, the FLM is tailored to learn resolution feature maps from different paths, facilitating the refinement of object representation and enhancing segmentation performance. Extensive experiments conducted on real natural scene datasets demonstrate the superiority of the proposed CRLNet over existing efficient segmentation methods in terms of accuracy. © 2025 IEEE.

DECOMPOSITION NUMBERS OF CYCLOTOMIC BRAUER ALGEBRAS OVER THE COMPLEX FIELD, I

Following Nazarov’s suggestion [23], we refer to the cyclotomic Nazarov-Wenzl algebra as the cyclotomic Brauer algebra. When the cyclotomic Brauer algebra is isomorphic to the endomorphism algebra of MIi,r– the tensor product of a simple scalar-type parabolic Verma module with the natural module in the parabolic BGG category O of types Bn, Cn and Dn, its decomposition numbers can theoretically be computed, based on general results from [1] and [29, Corollary 5.10]. This paper aims to establish explicit connections between the parabolic Verma modules that appear as subquotients of MIi,r and the right cell modules of the cyclotomic Brauer algebra under condition (1.12). It allows us to explicitly decompose MIi,r into a direct sum of indecomposable tilting modules by identifying their highest weights and multiplicities. Our result demonstrates that the decomposition numbers of such a cyclotomic Brauer algebra can be explicitly computed using the parabolic Kazhdan-Lusztig polynomials of types Bn, Cn, and Dn with suitable parabolic subgroups [32]. Finally, condition (1.12) is well-supported by a result of Wei Xiao presented in Section 6. Copyright © 2025, The Authors. All rights reserved.

A novel energy functional minimization model for speckle noise removal

Optoelectronics Letters 2019年第5期15卷 386-390页

作者： CHEN Bo ZOU Jin-bin CHEN Wen-sheng ZHANG Meng-yun Shenzhen Key Laboratory of Advanced Machine Learning and Applications College of Mathematics and Statistics Guangdong Key Laboratory of Intelligent Information Processing Shenzhen University

In this paper, a novel energy functional minimization model is proposed for ultrasound images denoising. A controllable regularized term and the variational method are employed in the process of speckle noise. This model not only improves the plasticity of the model, but also improves the effect and efficiency of noise removal. The new model has different diffusion performance in different regions. At the same time, the diffusion performance is related to the parameters introduced by the proposed model. Numerical simulation results show that different parameters have different denoising effects, and the proposed model for speckle noise removal is superior to traditional models.

A new scenario is considered that device-to-device (D2D) communication users underlay the spectrum resource of cellular user in distributed antenna systems (DAS) is discussed in this paper. We mainly focus on how to improve spectral efficiency (SE) and energy efficiency (EE) of the system. Under the maximum transmit power constraint per antenna unit, we propose two resource allocation algorithms to solve the optimal problems of maximum SE and EE. The first problem can be transformed into a difference of convex (DC) structure problem by function recombination, then the concave-convex procedure (CCCP) algorithm and the interior point method which are adopted to get the optimal solutions for the maximum SE. Subsequently, by using the Dinkelbach algorithm based on the parameter method, a power allocation algorithm for energy efficiency is developed to solve the maximum EE optimization problem. The optimal solutions are also obtained by the CCCP algorithm and the interior point method. Simulation results show that compared to co-located antenna systems (CAS) with D2D users, the SE and EE performances of the proposed system have a significant improvement. © Springer Nature Singapore Pte Ltd 2021.

Low-rank and sparsity are two popular regularization objects in hyperspectral image restoration. To generalize this decomposition, a weighted non-convex low-rank method is proposed by adopting non-convex lp -norm (0 p -norm can better approach the l0 -norm when 0 p -norm to the bases of the gradient of data. To remain faithful to the dissimilarity between the correlation along spatial and spectral directions, weights are assigned when computing the difference in each direction. Although being non-convex, the proposed model can be solved via ADMM algorithm. Extensive simulated experiments show that this model outperforms various existing methods visually and quantitatively. © 2021, Springer Nature Switzerland AG.

Automatic inspection of yarn locations by utilizing histogram segmentation and monotone hypothesis 1

We present an automatic method for the estimation of yarn locations in fabric images. The proposed method is based on histogram segmentation and a so-called monotone hypothesis which is a nonparametric statistical approach. In this method, accumulated partial derivatives histograms are statistically unimodal, which indicate the periodic structures of fabric images. Then, the monotone hypothesis is applied to divide the histograms into several segments. According to the maximum value and the minimum value of the histograms in each segment, the locations of yarn boundaries and yarn centers can be correspondingly estimated. The method reduces the influence of yarn random texture noise that comes from yarn hairiness, improving the accuracy of detection. Furthermore, compared with classical method based on image smoothing, the proposed method can avoid over-smoothing of the edges of yarns. © Springer Nature Switzerland AG 2019.

The Gelfand–Kirillov dimension is an invariant which can measure the size of infinitedimensional algebraic structures. In this article, we show that it can also measure the reducibility of scalar generalized Verma modules. In particular, we use it to determine the reducibility of scalar generalized Verma modules associated with maximal parabolic subalgebras in the Hermitian symmetric case.
