| Background Vincent van Gogh was an artist who profoundly expressed his inner emotions through both paintings and letters, with his sentiments manifesting in complex layers that correspond to the emotional turbulence of each period in his life. However, there is a notable lack of research that systematically compares and analyzes the temporal dynamics of his emotional expressions across these two distinct media-visual art and textual.
Methods This study extracted 7-dimensional emotion vectors from Van Gogh's paintings and letters using Open CLIP and GoEmotions-based BERT models. Dimensionality reduction techniques-PCA, t-SNE, and UMAP-were applied to construct emotional embedding spaces and visualize temporal emotion trajectories.
Result PCA analysis revealed a general shift toward more negative and intense emotions in later periods. In contrast, t-SNE and UMAP highlighted greater variability and non-linear transitions in emotional expression across media. Paintings exhibited more dispersed and dynamic emotional patterns, while letters showed a more cohesive and stable emotional flow.
Conclusion By comparing emotional trajectories in paintings and letters, this study offers an aesthetic framework for understanding Van Gogh's emotional evolution over time and highlights the complementary characteristics of emotion conveyed through different artistic media. |
