Abstract:

Rich in emotions and limited in samples constitute the artistic characteristic of Dongba paintings. The classification algorithm of learning attention could effectively assist the emotional classification of Dongba paintings, solving the problem of limited samples of Dongba paintings. Firstly, Dongba paintings were divided into 4 themes such as figures, ghosts, animals, and plants. According to the painting emotions, Dongba paintings were divided into 12 kinds of emotions, such as industriousness, simplicity, grace, and beauty. Secondly, the architecture of encoder and decoder was employed to extract their emotional features, while the pre-training model was used to improve the generalization performance of the classification model and accelerate the convergence of emotion classification for small samples of Dongba paintings. Finally, the blank attention was set in the decoder and the output sequence of the encoder was fused. Through the decoder, the semantics of Dongba paintings were learned, guiding the model to more accurately and reasonably improve the classification ability. Experiments show that the classification algorithm of learning attention could attain a classification accuracy of 80.7% higher than the existing methods, solving the problem of rich and difficult-to-distinguish emotions in Dongba paintings.

Key words: Dongba paintings, attention, emotion classification, encoder
