Automatic text summarization using deep reinforced model coupling contextualized word representation and attention mechanism

Multimedia Tools and Applications 2024年第1期83卷 733-762页

With the rapid and unprecedented growth of textual data in recent years, there is a remarkable need for automatic text summarization models to retrieve useful information from these large numbers of textual documents without human intervention within a reasonable time. Text summarization is commonly performed based on extractive and abstractive paradigms. Although different machine learning and deep learning based methods have been proposed for the task of text summarization during the last decades, they are still in their early steps of development and their potential has yet to be fully explored. Accordingly, a new summarization model is proposed in this paper which takes advantage of both extractive and abstractive text summarization models as a single unified model based on the strategy gradient of reinforcement learning. The proposed model also employs the combination of convolutional neural network and gated recurrent unit in both extraction and abstraction modules besides attention mechanism. Moreover, language models, namely Word2Vec and BERT, are used as the backbone of the proposed model to better express sentence semantics as a word vector. We conducted our experiments on widely-studied text summarization datasets (CNN\Daily Mail and DUC-2004) and according to the empirical results, not only the proposed model achieved higher accuracy compared to both extractive and abstractive summarization models in terms of ROUGE metric but also its generated summaries presented higher saliency and readability based on human evaluation. © 2023, The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature.

We present EPR-Net, a novel and effective deep learning approach that tackles a crucial challenge in biophysics: constructing potential landscapes for high-dimensional non-equilibrium steady-state ***-Net leverages a nice mathematical fact that the desired negative potential gradient is simply the orthogonal projection of the driving force of the underlying dynamics in a weighted inner-product ***, our loss function has an intimate connection with the steady entropy production rate(EPR),enabling simultaneous landscape construction and EPR estimation. We introduce an enhanced learning strategy for systems with small noise, and extend our framework to include dimensionality reduction and the state-dependent diffusion coefficient case in a unified fashion. Comparative evaluations on benchmark problems demonstrate the superior accuracy, effectiveness and robustness of EPR-Net compared to existing methods. We apply our approach to challenging biophysical problems, such as an eight-dimensional(8D)limit cycle and a 52D multi-stability problem, which provide accurate solutions and interesting insights on constructed landscapes. With its versatility and power, EPR-Net offers a promising solution for diverse landscape construction problems in biophysics.

The importance and growth of the Internet of Things (IoT) in computer networks and applications have been increasing. Additionally, many of these applications generate large volumes of data, which are critical and require protection against attacks. Various techniques have been proposed to identify and counteract these threats. In this paper, we offer a hybrid machine learning approach (using the k-nearest neighbors and random forests as supervised classifiers) to enhance the accuracy of intrusion detection systems and minimize the risk of potential attacks. Also, we employ backward elimination and linear discriminant analysis algorithms for feature reduction and to lower computational costs. Following the training phase, when discrepancies arose between the decisions of the classifiers, the ultimate determination was supported by ISO/IEC 27001 regulations. The performance of the proposed model was assessed within a Python programming framework, utilizing the CICIDS 2017, NSL-KDD, and TON-IoT datasets. The outcomes illustrated that the proposed approach attained a noteworthy accuracy of 99.96% in the multi-class classification of CICIDS 2017, 99.37% in the binary classification of the NSL-KDD dataset, and 99.96% in the multi-class classification of TON-IoT dataset. Furthermore, the attack success rate for each dataset stands at 0.05%, 0.24%, and 0% respectively, demonstrating a significant reduction compared to other methods. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.

Recently, the applications of Deep Learning (DL) methodologies have been extensively utilized across numerous areas to extract critical solutions from selected databases. The DL Segmentation Tool (DLST) is frequently utilized to extract and assess selected segments from digital images captured using various modalities. This study intends to propose a DLST to analyze the selected database for the identification of defects in solar cells. The proposed DLST encompasses several phases: (i) image acquisition and resizing, (ii) application of an image preprocessing technique to improve defect visibility, (iii) execution of the segmentation process utilizing a selected DL-model to extract the defect, and (iv) comparison of the segmented region with a binary mask and calculation of performance metrics. The created DLST incorporates the VGG-UNet, with VGG19 serving as the model's backbone. This work implemented a two-fold training approach for improved outcomes. The experimental result is validated using selected image metrics, demonstrating that the proposed DLST yields superior values of Jaccard (91.31%), Dice (95.38%), and Accuracy (96.18%) in comparison to other chosen DL models. © 2024 IEEE.

Breast Cancer (BC) is a predominant cause of mortality among women globally, with its incidence progressively rising due to various causes. Early detection of BC is crucial to plan and execute appropriate treatment to cure the disease. The clinical level examination of the BC involves in;personal check by the doctor, screening using non-invasive medical imaging modality, and biopsy test to confirm the BC and its stage. Compared to the radiological imaging modalities, the breast-ultrasound (BU) based screening is widely preferred due to its simplicity. The abnormality recorded with BU is then examined to classify the tumor as benign/malignant, an essential process during BC detection. This research aims to propose a deep-learning (DL) tool to segment the tumor from the chosen BU-image. To enhance the segmentation accuracy, every image is preprocessed using tri-level thresholding with Tsallis's Entropy and Hummingbird-Algorithm (TE+HA). The performance of proposed UNet/SegNet is verified on both unprocessed and preprocessed images. The experimental outcome of this research confirms that the VGG-UNet offered an improved mean accuracy (>97%) when the preprocessed BU is considered for examination. © 2024 IEEE.

Modern hospitals have extensively adopted the automatic disease examination methods to detect diseases from biomedical images of selected modalities. These methods reduce the diagnostic burden and enhance detection accuracy. This study seeks to create a Deep-Learning (DL) tool for the analysis of histopathology images related to colorectal cancer (CC). This DL-tool consists of the following stages: image collection and resizing, feature extraction using a selected DL-scheme, feature reduction through 50% dropout and serial feature fusion to create the Fused-Features-Vector (FFV), followed by binary classification and 3-fold cross-validation to validate the results. This study initially examines traditional DL-models for classification using SoftMax. Based on the results, the two best models are selected to generate the FFV. This study examines the features of VGG16 and ResNet101 to produce the FFV, thereby validating the effectiveness of the proposed scheme. The CC detection utilizing the FFV achieved an accuracy exceeding 95%, confirming that the developed scheme yields improved results on the selected data. © 2024 IEEE.
