This paper proposes a robust robot localization method with visually adaptive consensus filters (VACF) to solve the problem. The VACF consists of LiDAR odometry estimation, probabilistic localization, visual odometry estimation, optical flow recognition, object detection and adaptive consensus filters. To deal with long corridor environments, optical flow methods are used to correct the robot’s position. For robust localization in dynamic environments, object detection algorithm is used to detect dynamic objects, and localization algorithms are adaptively used as input to a consensus filter based on the number of dynamic objects detected.

This paper introduces a pioneering unlearning framework named FAST (Fine-tuning, Adverse Training, and Student–Teacher Methods). FAST is designed to selectively erase privacy-sensitive data while robustly safeguarding valuable information. It employs an innovative integration of the student–teacher architecture, utilizing targeted data and a sophisticated distribution structure refined by the Kullback–Leibler (KL) divergence within the loss function. Enhanced by fine-tuning and adverse training techniques, this integration amplifies beneficial knowledge from competent teachers and reduces ineffective knowledge from less capable ones, thereby enabling more effective and efficient unlearning processes. Furthermore, a new evaluation method called the Unlearning Effectiveness Score (UES) has been proposed for our unlearning model, aimed at providing a comprehensive metric to assess the effectiveness of the unlearning process. This approach rigorously evaluates the model using two sophisticated methods: the Zero Retrain Forgetting (ZRF) metric and Membership Inference Attacks (MIA). The UES is designed to not only measure the effectiveness of forgetting but also to ensure that the model is not easily susceptible to these attacks. These methods facilitate comprehensive comparisons with previous techniques such as bad teaching, Amnesiac, SCRUB, and straightforward fine-tuning. Our thorough experimental analysis, conducted across a variety of deep networks including MobileNet, ResNet, and VGG on the CIFAR and MUFAC datasets, confirms that FAST substantially surpasses existing approaches in both effectively forgetting targeted data and retaining necessary information, as demonstrated by its superior performance on UES metrics.</div></div>","PeriodicalId":48609,"journal":{"name":"Engineering Science and Technology-An International Journal-Jestech","volume":"64 ","pages":"Article 101996"},"PeriodicalIF":5.1,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143429535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although Ultra-Wideband (UWB) technology is renowned for its high precision in Line-of-Sight (LOS) environments, under NLOS conditions, positioning errors typically exceed 30 cm. To address this issue, we propose a method for identifying and classifying NLOS signals based on Support Vector Machine Recursive Feature Elimination (SVM-RFE). We extract multiple features from the UWB Channel Impulse Response (CIR) and perform correlation analysis using the Pearson Correlation Coefficient (PCC) to select the most discriminative features via the SVM-RFE algorithm. The classification results are then utilized within an Adaptive Robust Extended Kalman Filter (AREKF) to establish an error model for mitigation. The proposed method was evaluated using both a public dataset from Ghent University and a locally collected dataset. On the public dataset, the SVM-RFE algorithm achieved classification accuracies of 97.6% in the hallway environment and 96.6% in the office environment, outperforming transfer learning (TL) deep neural networks (DNNs) tested on the same dataset. To further validate the robustness of the algorithm, experiments on the locally collected office dataset demonstrated a classification accuracy of 97.2%. In terms of distance measurement error mitigation, the proposed AREKF algorithm reduced errors at the 95th percentile by 70% and 75% in two different environments compared to transfer learning methods on the same public dataset. When tested on the locally collected dataset, the positioning error of the AREKF was significantly lower than that of other mainstream algorithms, highlighting the practical advantages of the proposed method.</div></div>","PeriodicalId":48609,"journal":{"name":"Engineering Science and Technology-An International Journal-Jestech","volume":"63 ","pages":"Article 101979"},"PeriodicalIF":5.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143395907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The improved snow ablation optimizer algorithm optimizes hyperparameters of this network automatically, while the multi-head attention mechanism redistributes weighted features, integrating them into comprehensive features. Finally, predictions of spatial target trajectories are derived from outputs of fully connected layer. Through experiments on the constructed real dataset, it is evident that the improved snow ablation optimizer algorithm exhibits superior performance in optimization tasks. The sensor missing experiment underscore the advantages of multi-sensor data fusion. Furthermore, the ablation studies elucidate the functional disparities among various network architectures.

The maximum independent set problem is NP-hard for all types of graphs. The proposed method features a robust and greedy approach that produces results in polynomial time for all graph types. The proposed method is named the Differential Malatya Independent Set Algorithm (DMISA). The presented method also provides solutions to the minimum vertex cover and maximum clique problems, which are directly related to the independent set. The DMISA algorithm consists of two sub-algorithms. The first algorithm is the Differential Malatya Centrality Algorithm (DMCA), a centrality algorithm that calculates centrality values, providing prioritization in the selection of independent members. The second algorithm uses the DMCA value to select the independent set and vertex cover members in the graphs. In this study, the DMISA analytical proof has been applied to graphs with known solutions that can be solved in polynomial time. To emphasize the success of the algorithm, test operations have been conducted on various types of graphs. The conducted tests included 40 lattices, 40 bipartite, 24 multipartite, 32 social, and random graphs. The analysis results showed that DMISA produced optimal results in lattice, bipartite, and complete multipartite graphs, while it produced generally non-optimal results for randomly generated and social graphs.
