传统变压器状态评估方法,多关注设备当前状态分析,缺少全方位预测其潜在健康状态方法,也无法确定变压器将来的故障发生概率。本文提出了一种基于自适应概率神经网络的变压器健康状态评估方法。该方法,首先从变压器内部本体特征和外部实时监测环境两方面,确定变压器健康状态指标因子,并进行数据预处理得到不相关的指标因子;然后,根据指标因子和样本标签,引入自适应参数训练,训练出用于预测的概率神经网络模型;最后,利用模型参数,通过将指标分为静态基础指标和动态可变指标,前者直接输入到网络中 ...

随着互联网技术的发展,网络舆情热点信息能在短时间内迅速传播。预测舆情热点的发展趋势,有助于高校对学生思想健康状况进行分析管理,也是当下网络舆情信息研究领域的重要课题。针对微博中的舆情信息文本,构建基于时间编码长短期记忆网络(LSTM)的高校舆情热点趋势预测模型,并与支持向量机、循环神经网络两种模型的预测效果进行对比,验证了基于时间编码的LSTM算法在舆情趋势预测上的准确率。最后,利用微博中的高校实时舆情事件对构建的模型预测效果进行评估,并动态调整评估参数,实现了对评估性能的优化,预测效果得到了显著提升。

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

Abstract Adaptive management of threatened species relies on having ex ante estimates of species’ responses to different interventions. Structured expert elicitation is often used to generate these estimates, but comparisons of these expert‐predicted outcomes with observed results are rare.

Abstract Qualitative approaches are increasingly applied in conservation social science, yet methodological reflection remains limited. Member checking, a process of returning findings to participants for feedback, is widely recognized outside conservation as a means to enhance rigor and reciprocity, but it is rarely reported in conservation research ...

ABSTRACT Although the use of AI technologies (e.g., chatbots and automated writing evaluations (AWE)) has gained considerable attention in language learning fields in recent years, how AI technologies have been designed and implemented in language learning education, as well as their effectiveness, is understudied.
