In such cases, a fusion approach using an ensemble of Machine Learning (ML) techniques is proposed. The proposed methodology uses linear regression and random forest ML algorithms. The results are cross-checked against well-known datasets to demonstrate their estimation accuracy. A ML method is used to forecast the project’s effort, as some parameters required for work estimation may not be determinable at the beginning of the process. The model is trained using parametric training with fixed-size parameters, with the use case repository data serving as the training set and the China dataset as the test set. The proposed work uses an ensemble model to compute the fusion approach’s result, which is then inputted into a linear regression model. All regression models are then run individually to calculate the effort, and the efficiency of the proposed model is 94% which is a great improvement as compared to the individual model’s performance which is 74% only.</div></div>","PeriodicalId":56010,"journal":{"name":"Egyptian Informatics Journal","volume":"33 ","pages":"Article 100914"},"PeriodicalIF":4.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147396547","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}

Efficient data placement is essential for maximising data retrieval speed and overall system performance. EDPP leverages the combined power of MapReduce (MR) and Particle Swarm Optimisation (PSO) to address this challenge effectively. In these systems, files are divided into chunks, which can be either duplicates (pointing to existing data copies) or unique (requiring strategic placement). EDPP uses MR to identify the most suitable Data Nodes (DNs) for storing unique chunks, enhancing data retrieval efficiency. Furthermore, EDPP addresses the issue of maintaining balanced data distribution in heterogeneous clusters. By utilising PSO, it intelligently selects DNs based on their storage capacity and response times, ensuring optimal resource utilisation and load balancing. This research presents a practical and efficient solution to the complex problem of data placement in Big Data systems, offering significant benefits to organisations with diverse hardware and software configurations in their Hadoop clusters. Finally, experimental results demonstrate that the Enhanced Data Placement Policy (EDPP) significantly improves performance in Hadoop-based Big Data systems. The EDPP reduces data retrieval time by an average of 33 % compared to traditional methods and achieves a throughput of 35.03 MB/s with a 98 GB dataset, more than doubling the performance of the existing methods. Additionally, it ensures even data distribution, preventing node overload and optimising resource utilization.</div></div>","PeriodicalId":56010,"journal":{"name":"Egyptian Informatics Journal","volume":"33 ","pages":"Article 100878"},"PeriodicalIF":4.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145841261","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 these limitations, we propose SF-YOLOv9, a hybrid architecture that enhances YOLOv9c by improving the backbone through the integration of a novel PGI-Aware Swin Fusion Block (Transformer-GELAN) at its final stage.

It results in richer and more discriminative semantic representations. We introduce a Dual-Path Spatial and Channel Attention Module (DSCAM) into the main detection head and the reversible auxiliary branches of PGI. By refining attention across all supervisory signals, DSCAM significantly improves gradient flow and feature fidelity during PGI training, reducing missed detections and false positives.
