用视觉分析发现印度河文字与藏彝走廊文字高度相似，可能反映古代跨区域文化联系。
Rerouting Connection: Hybrid Computer Vision Analysis Reveals Visual Similarity Between Indus and Tibetan-Yi Corridor Writing Systems
- 结合卷积与Transformer模型，量化比较不同古文字的视觉特征
- 藏彝走廊文字与印度河文字相似度达0.635，是两河流域文字的六倍
- 结果支持南亚与东亚存在未被充分认识的文化传播网络
本研究采用混合CNN-Transformer架构与人类学框架，探究印度河文字与藏彝走廊象形系统在视觉形态上的潜在历史关联。通过15个独立训练模型对三种目标文字进行集成分析，结果显示藏彝走廊文字与印度河文字的视觉相似度约为0.635，是青铜时代原始苏美尔文（0.102）和原始埃兰文（0.078）的六倍。直接嵌入对比显示，印度河文字与藏彝走廊文字的平均余弦相似度为0.930（置信区间：[0.917, 0.942]），优于其与同期西亚符号系统的相似度（分别为0.887和0.855）。在多种降维与聚类方法下，印度河文字始终最接近藏彝走廊文字。计算结果与数字符号、性别标记及图像元素的视觉对应一致。考古证据表明，古蜀道沿线存在交流网络，时间上与印度河文明衰落重合，构成可能的传播路径。尽管其他解释仍存，但相似性的特异性与一致性暗示南亚与东亚间存在比以往认知更复杂的文化传播体系。
原文摘要 · Abstract (English)
This thesis employs a hybrid CNN-Transformer architecture, alongside a detailed anthropological framework, to investigate potential historical connections between the visual morphology of the Indus Valley script and pictographic systems of the Tibetan-Yi Corridor. Through an ensemble methodology of three target scripts across 15 independently trained models, we demonstrate that Tibetan-Yi Corridor scripts exhibit approximately six-fold higher visual similarity to the Indus script (0.635) than to the Bronze Age Proto-Cuneiform (0.102) or Proto-Elamite (0.078). Contrary to expectations, when measured through direct script-to-script embedding comparisons, the Indus script maps closer to Tibetan-Yi Corridor scripts with a mean cosine similarity of 0.930 (CI: [0.917, 0.942]) than to contemporaneous West Asian signaries, which recorded mean similarities of 0.887 (CI: [0.863, 0.911]) and 0.855 (CI: [0.818, 0.891]). Across dimensionality reduction and clustering methods, the Indus script consistently clusters closest to Tibetan-Yi Corridor scripts. These computational findings align with observed pictorial parallels in numeral systems, gender markers, and iconographic elements. Archaeological evidence of contact networks along the ancient Shu-Shendu road, coinciding with the Indus Civilization's decline, provides a plausible transmission pathway. While alternate explanations cannot be ruled out, the specificity and consistency of similarities suggest more complex cultural transmission networks between South and East Asia than previously recognized.
