湍流的研究离不开高分辨率的流场数据,但受测量方法、计算效率和数据存储等多方面限制,高分辨率湍流数据的直接获取仍比较困难。本文基于流场时程数据的低维表征模型,提出基于神经网络的特征编码预测模型与高分辨率的湍流重构方法。首先,基于一维卷积方法建立湍流时程的低维表征模型;然后,基于人工神经网络模型建立测点坐标与特征编码之间的映射关系,实现未知测点的特征编码预测;最后,利用所预测的特征编码结合表征模型的解码器生成求解域内任意位置处的湍流时程。对Re=2.2×10^(4)的方柱湍流场进行低维表征,进而实现高分辨率流场时程数据的重构,并验证方法的准确性。本文所提方法是一种在时间维度上具有高精度的湍流重构方法,且是一种无监督训练方法,可广泛应用于基于一点的传感器数据处理,是一种适用于湍流流场时程数据重构的新方法。

在ChatGPT展现出其强大的自然语言输出能力后,乔姆斯基依据其“转换生成语法”理论对大语言模型的运行方式进行了批评,认为大语言模型不具备像人一样的内在语言生成能力,也无法提出任何因果机制和科学规律,只是一种非科学的“虚假承诺”。但大语言模型的成功证明语言能力可以通过深度学习和神经网络技术获取,传统语言学理论无法为这一技术进步的理由奠基,反而在哲学立场上与乔姆斯基完全对立的维特根斯坦的语言哲学思想可以对大语言模型的实质进行说明与澄清。文章将从维特根斯坦的有穷主义和建构主义立场出发,结合维特根斯坦对数学基础与语言形成的澄清,将大语言模型定义为一种有边界的数学化世界模型,并指出大语言模型的成功应用事实上证明了维特根斯坦语言哲学的正确。
