The RCN improves offender profiling for more accurate and interpretable recidivism predictions, aligning with key legal principles like fair sentencing, transparency, and non-discrimination. The RCN employs machine learning (ML) models optimized with a Keras tuner, using the Synthetic Minority Over-sampling Technique (SMOTE) to handle class imbalance. With about 75% accuracy, the model shows strong recall, identifying 10,661 recidivists but producing 4,038 false positives—indicating a trade-off between sensitivity and specificity. Beyond predictions, RCN integrates clustering methods, including k-means, principal component analysis (PCA), and t-distributed Stochastic Neighbor Embedding (t-SNE), to identify hidden patterns within offender data. Visualizations reveal distinct clusters, linking characteristics, such as age, to recidivism behaviors. SHapley Additive exPlanations (SHAP) values enhance interpretability, showing that factors like time since the last conviction and age significantly impact predictions. The RCN approach offers substantial potential for criminal justice applications by combining predictive power with actionable insights, supporting a more ethical and accountable use of ML in offender profiling and aiding in fairer recidivism prevention strategies.

This paper introduces LHFF-MIL, a novel framework that emphasizes latent feature decoding and fusion in MIL. Our key contribution is the Latent Feature Distribution Decoder (LFDD), which efficiently decodes diverse information from high-dimensional semantics across different WSI resolutions, enabling explicit measurement of image informativeness for tumor detection. Evaluated on three real-world datasets of breast and gastric cancer, LHFF-MIL consistently outperforms competing methods, demonstrating statistically significant diagnostic accuracy improvement from 0.27% to 1.44% with at least 95% of confidence level.

Traditional methodologies often encounter difficulties in effectively retrieving pertinent information. In contrast, swarm intelligence techniques, which optimize through collaborative interaction and stochastic exploration without dependence on prior knowledge, are more adept at addressing image segmentation challenges. The Tree-Seed Algorithm (TSA), a prominent swarm intelligence optimization technique, has been extensively utilized to tackle intricate optimization issues. Nonetheless, the reliance on a singular seed generation approach may result in inadequate exploration, premature convergence, diminished diversity, and local stagnation. To address these deficiencies, a hybrid variant known as the Tree-Seed-Gene Algorithm (TSGA) is proposed, drawing inspiration from the Genetic Algorithm (GA) and incorporating a double search strategy that integrates genetic and automated learning strategies. The genetic search contains mechanisms such as elite, crossover, and mutation. Furthermore, an opposition-based learning strategy is introduced to bolster population diversity, thereby enhancing exploration capability. The efficacy of the TSGA algorithm is assessed in comparison to both classical and contemporary meta-heuristic algorithms, including their variants, utilizing benchmark functions from the IEEE CEC 2014, 2017, 2020, and 2022. The performance of the TSGA is substantiated through statistical analyses, specifically, the Wilcoxon signed-rank and Friedman tests. The findings indicate that the TSGA algorithm exhibits superior performance in resolving image segmentation issues. In conclusion, the experimental results consistently affirm the TSGA has significant potential for practical applications in the domain of image segmentation.</div></div>","PeriodicalId":50737,"journal":{"name":"Applied Soft Computing","volume":"176 ","pages":"Article 113143"},"PeriodicalIF":7.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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, it still suffers from premature convergence or stagnation when dealing with complex optimization problems. To avoid these dilemmas in the DE algorithm, we propose a novel DE variant, abbreviated as PISCDE, which is based on periodic intervention and strategic collaboration mechanisms. PISCDE incorporates two types of operations: routine operation and intervention operation. The routine operation employs two mutation strategies with different functional positions to drive the population toward the optimal position. In contrast, the intervention operation uses two intervention strategies with distinct functional roles to restore population diversity and is executed only when a fixed number of iterations is reached. Additionally, to achieve a better balance between global exploration and local exploitation during the optimization process, we propose several strategic collaboration mechanisms. These mechanisms are based on the positioning analysis of different strategies and the interaction analysis between strategies and their corresponding control parameters. To verify the optimization performance of PISCDE, we selected nine comparison algorithms with outstanding optimization performance that have been proposed in the last five years. We used the IEEE CEC 2014 testbed to construct comparative experiments. Based on the comparative results, three conclusions can be drawn: (1) PISCDE has the best overall optimization performance among all the algorithms.
