The user-specific interests are the main requirement to build any recommendation model that produces the desired recommendation list. But the users' interests are sometimes unpredictable due to the fluctuating nature of the arrival of newer products. To resolve this problem and achieve better recommendation outcomes, a two-tier enhanced hybrid collaborative filtering based recommendation system (EHCFR) is constructed in this work based on deep learning. Initially, users in the dataset are segmented based on their age stratification to obtain users' interests based on age. Then, the major features are extracted from the dataset using the word learning enhanced variational auto-encoder (EVAE). These features are provided along with the rating matrix as the input to the deep belief network (DBN) for rating prediction. Based on the predicted ratings, the top N1 recommendation list is generated. Then, a time window strategy is adapted in the model to determine the dynamic fluctuations of user interests. Another list called the top N2 recommendation list is generated based on these fluctuations. Finally, both these lists are concatenated to provide accurate and favorable recommendations to the users. The proposed model is tested on the user dataset and provides competitive performance against the existing state-of-the-art techniques. Also, a reliable comparison is made with the existing popular datasets, such as Movielens 100k and Jester, and the results prove the efficacy of the proposed method.</p>\u0000 </div>","PeriodicalId":55228,"journal":{"name":"Computational Intelligence","volume":"41 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among various emotions, facial expressions are widely informative as they exhibit a person's intentions and character. Facial expression recognition is used in many applications, such as marketing, research, customer service, neuroscience, and psychology. Traditional unimodal methods for facial expression recognition are ineffective due to the scarcity of data. In this paper, the Residual Fused Neuro-Fuzzy Network (RF-NFN) is used for the recognition of facial expressions and detection of emotion type using video and Electroencephalogram (EEG) signals. Here, the video frame is allowed for pre-processing done by Non-Local Means (NLM) filtering. Then, pre-processed video frames and input EEG signals are fed toward feature extraction, which is then followed by feature selection. Finally, facial expressions are recognized and the type of emotion is detected by RF-NFN, which is designed by incorporation of Hybrid Cascade Neuro-Fuzzy Network (Hybrid Cascade NFN) and Deep Residual Network (DRN). Moreover, the performance of the RF-NFN model is validated by three performance measures that exhibited a maximum accuracy of 90.88%, precision of 91.77%, and recall of 94.57%.</p>\u0000 </div>","PeriodicalId":55228,"journal":{"name":"Computational Intelligence","volume":"41 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, they suffered from challenges of rapid motion and complex scenes in video super-resolution. In this paper, we present a deformable convolutional neural network for video super-resolution (DVSRNet). DVSRNet mainly contains forward and backward feature propagation blocks (FPBs), feature enhancement blocks (FEBs), a feature fusion block (FFB), and a reconstruction block (RB). FPBs can leverage temporal sequence information to capture rich temporal dimensional information in video super-resolution. To restore detailed information, an optical flow technique guided a CNN to align the obtained structural information of different frames to reduce motion-induced blur and artifacts. To address deformable videos from motioned objects, two FEBs utilized deformable convolutions to adaptively correct misaligned objects to improve spatial continuity of videos. To improve reliability of obtained videos, an FFB is used to integrate relations of different video frames from forward and backward propagations. Finally, an RB via upsampling operations and a residual learning technique is used to construct high-quality videos. Experimental results demonstrate that our DVSRNet exhibits superior performance on multiple public datasets for video super-resolution. Its codes can be available at https://github.com/leyoukai/DVSRNet.</p>\u0000 </div>","PeriodicalId":55228,"journal":{"name":"Computational Intelligence","volume":"41 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143901086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
