Fig. 7From: Classification of chest X-ray images by incorporation of medical domain knowledge into operation branch networksScatter plot of Attention Index for heart failure classification in the Tokushima dataset. Left column, conventional DenseNet121. Right column, original attention branch network. The horizontal axis shows the attention index value in the attention branch network. The vertical axis shows those of others: OBN1, operation branch network using weight maps with a convex hull mask of lung field; OBN2, operation branch network using weight maps with lung field and heart mask; OBN3, operation branch network created manually by an experienced doctor using weight mapsBack to article page
