This study evaluates the performance of 15 machine learning models for predicting energy consumption (30–100 kWh/m2·year) and occupant dissatisfaction (Percentage Dissatisfied, PPD: 6–90%), key metrics optimizing building performance. Ten evaluation metrics, including Mean Absolute Error (MAE, average prediction error), Root Squared (RMSE, penalizing large errors), coefficient determination (R2, variance explained by model), are used. XGBoost achieves highest accuracy, with an MAE 1.55 kWh/m2·year a PPD 3.14%, alongside R2 values 0.99 0.97, respectively. While these highlight XGBoost’s superiority, its margin improvement over LightGBM (energy MAE: 2.35 kWh/m2·year, 3.89%) is context-dependent, suggesting application in high-precision scenarios. ANN excelled at predictions, achieving lowest (1.55%) Percentage (MAPE: 4.97%), demonstrating ability to model complex nonlinear relationships. modeling advantage contrasts LightGBM’s balance speed making it suitable computationally constrained tasks. In contrast, traditional like linear regression KNN exhibit high errors (e.g., 17.56 17.89%), underscoring their limitations respect capturing complexities datasets. The results indicate that advanced methods particularly effective owing intricate relationships manage high-dimensional data. Future research should validate findings diverse real-world datasets, those representing varying types climates. Hybrid combining interpretability precision ensemble or neural be explored. Additionally, integrating techniques digital twin platforms could address real-time optimization challenges, dynamic behavior time-dependent consumption.

Abstract Women suffer great psychological pressure on the postpartum recovery period, which can cause certain diseases in long run if not paid attention to. Based research related to principle of health parameter detection and feature extraction method pulse wave data, study was conducted by extracting physiological signal features normal pulse, using improved support vector machine (OC-SVM) for abnormality detection, adding attention-based two-stage short-term memory network (DA-LSTM) AE, adaptively directs weights input sequences encoding/decoding stages, respectively allocation selecting hidden state encoder time step, respectively. Then, based experimental development monitoring system carried out from three major modules, namely, main control module, front-end acquisition processing auxiliary realize intervention recovery. Using this paper carry a three-month experiment women, it is found that group after each index value has decreased rate decrease large, somatization (1.26 ± 0.13) (1.09 0.58), compared with before significant difference (P < 0.05), help women recover their level more quickly childbirth.

Introduction Postpartum depression (PPD) has numerous adverse impacts on the families of new mothers and society at large. Early identification intervention are great significance. Although there many existing machine learning classifiers for PPD prediction, requirements high accuracy interpretability models present challenges. Methods This paper designs an ensemble neural network model predicting PPD, which combines a Fully Connected Neural Network (FCNN) with Dropout mechanism (DNN). The weights FCNN DNN in proposed determined by their accuracies training set respective values. structure is simple straightforward. connection pattern among neurons makes it easy to understand relationship between features target feature, endowing interpretability. Moreover, does not directly rely prevent overfitting. Its more stable than that DNN, weakens negative impact model. At same time, reduces overfitting risk enhances its generalization ability, enabling better adapt different clinical data. Results achieved following performance metrics dataset: 0.933, precision 0.958, recall 0.939, F1-score 0.948, Matthews Correlation Coefficient (MCC) 0.855, specificity 0.923, Negative Predictive Value (NPV) 0.889, False Positive Rate (FPR) 0.077, (FNR) 0.061. Compared 10 classic classifiers, under dataset split ratios, outperforms terms indicators such as accuracy, precision, recall, F1-score, also stability. Discussion research results show effectively improves prediction can provide guiding suggestions relevant medical staff postpartum women decision-making. In future, plans include collecting disease datasets, using predict these diseases, constructing online platform embed model, will help real-time prediction.
