Typically, the popular trackers adopt pre-trained ResNet as a backbone to extract target features, achieving excellent performance. Moreover, Staple has shown that color statistics have complementary cues, while the combination of color statistics and deep features in a unified deep framework has rarely been reported. Therefore, we employ color statistics to construct color attention maps, which are encoded into the deep network to guide the generation of target-aware feature maps. Additionally, DCF-based trackers have an online update module to dynamically update the tracking model, it is particularly necessary to collect reliable target samples. Hence, we refer to the template matching thought to design a score matching method, which is intended to score the tracked targets, this method has the advantage of considering the target extent. In this paper, we conduct sufficient ablation analyses on the color attention module and score matching method to verify their effectiveness. Furthermore, our approaches are combined into the DCF frameworks to construct two brand-new trackers, and both quantitative and qualitative results demonstrate that our trackers can perform favorably against recent and far more sophisticated trackers on multiple public benchmarks.","PeriodicalId":51327,"journal":{"name":"International Journal of Machine Learning and Cybernetics","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although deep learning (DL) models are well suited for detecting and segmenting multi-class hemorrhages, localizing multi-scale mixed hemorrhages with limited resources such as bounding boxes is difficult. To address this issue, the current study proposes a novel transfer learning-based TL-LFF Network. To detect multi-scale mixed hemorrhages, the proposed model employs a backbone module that extracts in-depth features from the input images, and a spatial pyramid pooling faster layer that performs the pooling operation at various levels. In the neck section, a path aggregated network (PANet) is used to store spatial information. Furthermore, to achieve a lightweight nature, the proposed backbone and neck modules were frozen during the backpropagation stage, resulting in a decrease in detection accuracy. To improve detection capability while remaining lightweight, a concept known as transfer learning is used. This strategy significantly improves the accuracy of the proposed model. In addition, the Genetic Algorithm (GA) concept is used to optimize the hyperparameters, where the mutation is used to develop new offspring based on previous generations. The brain hemorrhage extended dataset was used to train and validate the proposed model. In terms of detection metrics and lightweight criteria, the experimental results showed that the proposed model performed better when compared to other existing models. As a result, we can use the proposed model in the clinical implementation stage to reduce the radiologist's CT scan read time.","PeriodicalId":51327,"journal":{"name":"International Journal of Machine Learning and Cybernetics","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Textual fake news detection methods can be categorized into pattern- and fact-based. Pattern-based models focus on identifying shared writing patterns in source posts, while fact-based models leverage auxiliary external knowledge. Researchers have recently attempted to merge these two views into a comprehensive detection system, achieving superior performance to single-view methods. However, existing dual-view methods often prioritize integrating single-view methods over exploring nuanced characteristics of both perspectives. To address this, we propose a novel hierarchical dual-view model for fake news detection guided by discriminative lexicons. First, we construct two lexicons based on distinct word usage tendencies in fake and real news and further augment them with synonyms sourced from large language models. We then devise a hierarchical attention network to derive semantic representations for the source post, incorporating a lexicon attention loss to guide the prioritization of words from the two lexicons. Subsequently, a lexicon-guided interaction network is employed to model the relations between the source post and its relevant articles, assigning authenticity-aware weights to each article. Finally, the representations of source post and relevant articles are concatenated for joint detection. According to experimental results, our model outperforms many competitive baselines in terms of the macro F1 score ranging from 1.1% to 10.5% on Weibo and from 3.2% to 10.8% on Twitter.","PeriodicalId":51327,"journal":{"name":"International Journal of Machine Learning and Cybernetics","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, Domain Adaptive Retrieval (DAR) has emerged as a promising solution, specifically designed to overcome domain shifts in retrieval tasks. However, existing unsupervised DAR methods still face two primary limitations: (1) they under-explore the intrinsic structure among domains, resulting in limited generalization capabilities; and (2) the models are often too complex to be applied to large-scale datasets. To tackle these limitations, we propose a novel unsupervised DAR method named Anchor-based Domain Adaptive Hashing (ADAH). ADAH aims to exploit the commonalities among domains with the assumption that a consensus latent space exists for the source and target domains. To achieve this, an anchor-based similarity reconstruction scheme is proposed, which learns a set of domain-shared anchors and domain-specific anchor graphs, and then reconstructs the similarity matrix with these anchor graphs, thereby effectively exploiting inter- and intra-domain similarity structures. Subsequently, by treating the anchor graphs as feature embeddings, we solve the Distance-Distance Difference Minimization (DDDM) problem between them and their corresponding hash codes. This preserves the similarity structure of the similarity matrix in the hash code. Finally, a two-stage strategy is employed to derive the hash function, ensuring its effectiveness and scalability. Experimental results on four datasets demonstrate the effectiveness of the proposed method.","PeriodicalId":51327,"journal":{"name":"International Journal of Machine Learning and Cybernetics","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, with the emergence of deep learning technology based on big data, the extraction of information relations in the field of agri-food safety supervision has become a research hotspot. However, most of the current work only expands the relationship recognition based on the traditional named entity recognition task, which makes it difficult to establish a true 'connection' between entities and relationships. The pipelined and federated extraction architectures that have emerged in this area are problematic in practice. In addition, the contextual information of the text corpus in the agri-food safety regulatory domain has not been fully utilized. To address the above issues, this paper proposes a semi-joint entity relationship extraction model (EB-SJRE) based on contextual entity boundary features. Firstly, a Token pair subject-object correspondence matrix label is designed to intuitively model the subject-object boundary, which is more friendly to complex entities in the field of agri-food safety regulation. Secondly, the dynamic fine-tuning of Bert makes the text embedding more relevant to the textual context of the agri-food safety regulation domain. Finally, we introduce an attention mechanism in the Token pair tagging framework to capture deep semantic subject-object boundary association information, which cleverly solves the problem of bias exposure due to the pipeline structure and the dimensional explosion due to the joint extraction structure. The experimental results show that our model achieves the best F1-score of 88.71% on agri-food safety regulation domain data and F1-scores of 92.36%, 92.80%, 88.91%, and 92.21% on NYT, NYT-star, WebNLG, and WebNLG-star, respectively. This indicates that EB-SJRE has excellent generalization ability in both the agri-food safety regulatory and public sectors.","PeriodicalId":51327,"journal":{"name":"International Journal of Machine Learning and Cybernetics","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Second, the pseudo-labelling generation is optimized based on the CLIP model to expand the diversity of the training set and enhance the ability to cover unknown object categories. We validated this method on four challenging datasets: MSCOCO, ILSVRC, Visual Genome, and PASCAL VOC.

Recently, there has been a growing interest in the cross-modal hashing retrieval approach. Nonetheless, a significant number of current methodologies overlook the influence of semantically rich features on retrieval performance. In addition, class attribute embedding is often forgotten in cross-modal feature fusion, which is crucial for learning more discriminative hash codes. To meet these challenges, we put forward a novel method, namely joint feature fusion hashing (JFFH) for cross-modal retrieval. Specifically, we use the fast language image pre-training model as the feature coding module of cross-modal data. To more effectively mitigate semantic disparities between modalities, we introduce a multimodal contrastive learning loss to strengthen the interaction between modalities and improve the semantic representation of modalities. In addition, we extract class attribute features as class embedding and integrate them with cross-modal features to enhance the semantic relationship within the fused features. To better capture both inter-modal and intra-modal dependencies as well as semantic relevance, we integrate the self-attention mechanism into the multi-modal fusion transformer encoder to facilitate efficient feature fusion. Besides, we apply label-wise high-level semantic similarity and feature-wise low-level semantic similarity to enhance the discrimination of hash codes. Our JFFH method shows better retrieval performance in large-scale cross-modal retrieval.","PeriodicalId":51327,"journal":{"name":"International Journal of Machine Learning and Cybernetics","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
