Previous studies, however, have exclusively focused on univariate prediction models, neglecting the information from other variables, and have not fully exploited the prediction errors in their loss function during training. To address these issues, an interpretable dual-output multivariate wind speed interval prediction scheme (IMWSIPS) that utilizes a hyper-heuristic optimization algorithm and a deep neural network is proposed, along with a novel loss function for training. The system initially takes multiple inputs such as historical wind speed and other influencing factors including wind direction, density, temperature, and pressure into a deep neural network. The actual wind speeds are then scaled up and down by factors of 1 + θ<sub>1</sub> (0 <θ<sub>1</sub><1) and 1 + θ<sub>2</sub> (-1 <θ<sub>2</sub><0), respectively, to produce two outputs from the network. On this basis, an optimization problem to minimize interval width under a given coverage probability is formulated and solved using the developed hyper-heuristic algorithm, yielding optimal values for θ<sub>1</sub> and θ<sub>2</sub> and the prediction intervals for sub-models. Subsequently, the advantages of five deep neural network models are leveraged to construct an ensemble model, with weights optimized by the hyper-heuristic algorithm to derive the final prediction intervals. Ultimately, the system's interpretability is analyzed at both variable and sub-model levels. Experimental and discussion results demonstrate that the introduction of IMWSIPS not only signifies enhancements in forecasting performance but also implies improvements in wind energy utilization efficiency and reductions in operational costs for power systems.</div></div>","PeriodicalId":50737,"journal":{"name":"Applied Soft Computing","volume":"185 ","pages":"Article 113829"},"PeriodicalIF":6.6,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145050478","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}

FedAlign overcomes this problem by employing similarity transformation matrices to align state representations of local SSMs, thereby establishing a common parameter basin that retains the dynamics of local SSMs. FedAlign computes similarity transformation matrices via two distinct approaches. In FedAlign-A, we represent the global SSM in controllable canonical form (CCF). We use control theory to analytically derive similarity transformation matrices that convert each local SSM into this form. Yet, establishing global SSM in CCF brings additional alignment challenges in multi-input multi-output SYSID, as CCF representation is not unique, unlike in single-input single-output SYSID. In FedAlign-O, we address the alignment challenges by reformulating the local parameter basin alignment problem as an optimization task. We set the parameter basin of a local worker as the common parameter basin and solve least square problems to obtain the transformation matrices needed to align the remaining local SSMs. The experiments conducted on synthetic and real-world datasets show that FedAlign outperforms FedAvg, converges faster, and provides improved global SSM stability thanks to local parameter basins’ alignment.</div></div>","PeriodicalId":50737,"journal":{"name":"Applied Soft Computing","volume":"184 ","pages":"Article 113800"},"PeriodicalIF":6.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145010138","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}
