Experimental results demonstrate that the proposed predictor achieves the best forecasting results compared to other benchmark models, proving its precision stability and outperformance. Moreover, the paper validates the proposed predictor's power efficiency by measuring its real-time power consumption and temperature during the training process. The proposed predictor reduces the average consumed power by 5% compared to a classical sparse AE-BiGRU.

Summary: This study investigates the adoption of blockchain technology (BCT) for verifying product recycling information (VPRI) in the presence of original and green consumers. Three modes of the manufacturer are analyzed: no adoption of BCT, adopting own BCT, and adopting a third-party BCT platform for VPRI. The results show that the manufacturer's adoption mode depends on the scaling cost and the proportion of BCT verified to all recycling information. Furthermore, the study finds that BCT adoption can have negative environmental impacts, especially when the carbon emission rate of recycled products is higher.

Summary: In this article, a stochastic recurrent encoder-decoder neural network (SREDNN) is developed for generative multistep probabilistic wind power predictions. The SREDNN considers latent random variables in its recurrent structures and provides two critical advantages compared to conventional RNN-based methods: it models wind power distribution using an infinite Gaussian mixture model (IGMM) and describes complex patterns across wind speed and power sequences by updating hidden states in a stochastic way. Computational experiments demonstrate the advantages and effectiveness of the SREDNN for wind power prediction.
