Figure 3

Example heatmaps for (a) low value images that were mislabeled as pneumonia, (b) low value images that were mislabeled as no pneumonia, (c) high value images that were mislabeled as pneumonia. (a) Heatmaps show low activations in relevant areas in the lung but high activations in irrelevant areas outside the lung, suggesting that the input feature vectors favored no pneumonia over pneumonia. (b) Heatmaps show high activations in lung areas indicating pneumonia, suggesting that the input feature vectors favored pneumonia over no pneumonia. (c) Heatmaps show high activations in abnormal lung areas. The first three images show abnormal opacity. The fourth image shows interstitial patterns, predominantly in the upper lung fields. The last image shows abnormal mass in the upper right lung field (i.e. upper left of the image).
