However, most existing techniques encounter the challenge of k parameter due to the involvement of k nearest neighbor (kNN). Furthermore, they only adopt one sole neighborhood rule, disregarding the positional characteristics of minority samples. This often leads to the generation of synthetic noise or overlapping samples. This paper proposes a non-parameter oversampling framework called the hybrid natural neighbor synthetic minority oversampling technique (HNaNSMOTE). HNaNSMOTE effectively determines an appropriate k value through iterative search and adopts a hybrid neighborhood rule for each minority sample to generate more representative and diverse synthetic samples. Specifically, 1) a hybrid natural neighbor search procedure is conducted on the entire dataset to obtain a data-related k value, which eliminates the need for manually preset parameters. Different natural neighbors are formed for each sample to better identify the positional characteristics of minority samples during the procedure. 2) To improve the quality of the generated samples, the hybrid natural neighbor (HNaN) concept has been proposed. HNaN utilizes kNN and reverse kNN to find neighbors adaptively based on the distribution of minority samples. It is beneficial for mitigating the generation of synthetic noise or overlapping samples since it takes into account the existence of majority samples. Experimental results on 32 benchmark binary datasets with three classifiers demonstrate that HNaNSMOTE outperforms numerous state-of-the-art oversampling techniques for imbalanced classification in terms of Sensitivity and G-mean.</p></div>","PeriodicalId":8041,"journal":{"name":"Applied Intelligence","volume":"55 5","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142995666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, their ability to reason about interactions accurately and in-depth remains limited. Therefore, we propose a knowledge-guided interaction perception module that combines multiple relationship information with CLIP’s visual feature information. Then, we utilize prior interaction knowledge from intersection regions to guide the process, resulting in more accurate human-object interaction detection. Moreover, we find that the potential interaction of images relies on subtle visual cues but is masked by other irrelevant information, making it difficult for algorithms to capture the basic features of interaction accurately. To address this, we have designed a human-object salient region enhancement module to enhance the feature information of humans and objects and enable better interaction pairing.

Regular detection of defects in the insulator surface and replacement of defective insulators in time are a must for the operation of the safety system.

However, the existing detection models mainly operate in very limited weather condition, faltering in generalization and practicality in the wild. To aid in the status quo, this paper proposes a new framework that enables accurate detection of insulator defects in adverse weather conditions, where atmospheric particulates can substantially degrade the quality of aerial images on insulator surfaces. Our proposed framework is embarrassingly simple, yet effective.
