<abstract> <p>In the evolving field of solar energy, precise forecasting Solar Irradiance (SI) stands as a pivotal challenge for optimization photovoltaic (PV) systems. Addressing inadequacies in current techniques, we introduced advanced machine learning models, namely Rectified Linear Unit Activation with Adaptive Moment Estimation Neural Network (RELAD-ANN) and Support Vector Machine Individual Parameter Features (LSIPF). These models broke new ground by striking an unprecedented balance between computational efficiency predictive accuracy, specifically engineered to overcome common pitfalls such overfitting data inconsistency. The RELAD-ANN model, its multi-layer architecture, sets standard detecting nuanced dynamics SI meteorological variables. By integrating sophisticated regression methods like Regression (SVR) Lightweight Gradient Boosting Machines (Light GBM), our results illuminated intricate relationship influencing factors, marking novel contribution domain energy forecasting. With R<sup>2</sup> 0.935, MAE 8.20, MAPE 3.48%, model outshone other signifying potential accurate reliable forecasting, when compared existing Multi-Layer Perceptron, Long Short-Term Memory (LSTM), Multilayer-LSTM, Gated Recurrent Unit, 1-dimensional Convolutional Network, while LSIPF showed limitations ability. Light GBM emerged robust approach evaluating environmental influences on SI, outperforming SVR model. Our findings contributed significantly systems could be applied globally, offering promising direction renewable management real-time forecasting.</p> </abstract>

Human activity recognition is an essential task for human-centered intelligent systems such as healthcare and smart vehicles, which can be accomplished by analyzing time-series signals collected from sensors in wearable devices. In these applications, real-time response vital because prompt action necessary urgent events elderly person falling or driving while drowsy. Although recurrent neural networks have been widely used owing to their temporal modeling capabilities, recent studies focused on convolutional (CNNs) that are suitable responses they incur lower computational costs. However, CNNs with a manual design may fail achieve optimal accuracy due varying budgets applications this paper, we propose novel framework uses mathematical approach derive CNN architecture given budget. As result, introduce grouped shift network (GTSNet) the flexibly modified predefining theoretical computation cost. We demonstrate effectiveness of our experiments, achieving best performance well-known public benchmark datasets under limited budgets. The source codes GTSNet publicly available at https://github.com/jgpark92/GTSNet.

Precise machining of micro parts from difficult-to-cut materials requires using advanced technology such as wire electrical discharge (WEDM). In order to enhance the productivity WEDM, key role is understanding influence process parameters on surface topography and material’s removal rate (MRR). Furthermore, effective models which allow us predict micro-WEDM qualitative effects are required. This paper influences energy, time interval, speed topography’s properties, namely Sa, Sk, Spk, Svk, MRR, after Inconel 718 were described. Developed RSM ANN model process, showing that energy had main (over 70%) parameters. However, for interval was also significant. a reduction in can lead decrease cost have positive environment sustainability process. Evaluation developed prediction indicates lower value relative error compared with did not exceed 4%.

Poverty, an intricate global challenge influenced by economic, political, and social elements, is characterized a deficiency in crucial resources, necessitating collective efforts towards its mitigation as embodied the United Nations' Sustainable Development Goals. The Gini coefficient statistical instrument used nations to measure income inequality, economic status, disparity, escalated inequality often parallels high poverty rates.
