Emotion Inference Averagely +37.4% in terms of F1 SVM: regards the visual features of images as inputs and uses a SVM as a classifier. PFG: considers both color features and social correlations among images. LDA+SVM: first uses LDA to extract latent topics from comments, then uses visual features, topic distributions, and social ties as features to train a SVM. 11
Image Interpretations • Our model demonstrates how visual features distribute over different emotions. (e.g., images representing Happiness have high saturation) • Positive emotions attract more response ( +4.4 times) and more easily to influence others compared with negative emotions. 12
• We study the problem of inferring emotions of images from a new perspective by bringing in comment information. • Thanks! • Code & Data: – http://aminer.org/emotion 13
