I just got a great question asking why there is a discrepancy in the accuracy reported in our two works:

[ISBI paper, we report 81.8% accuracy over 10 classes]
Kawahara, J., BenTaieb, A., & Hamarneh, G. (2016). Deep features to classify skin lesions. In IEEE ISBI (pp. 1397–1400). Summary and slides here.

[MICCAI MLMI paper, we report 74.1% accuracy over 10 classes]
Kawahara, J., & Hamarneh, G. (2016). Multi-Resolution-Tract CNN with Hybrid Pretrained and Skin-Lesion Trained Layers. In MLMI. Summary and slides here.

We use the same Dermofit dataset, so it seems surprising the accuracy we report in the papers are different. So I thought I would elaborate on why here.

Here I'm nervously just starting our talk on our approach to skin lesion classification — Me nervously just starting to talk about our approach to skin lesion classification.

We presented our work, “Deep Features to Classify Skin Lesions” at ISBI 2016 in Prague! And I’m happy to report that our work was awarded runner-up for the Best Student Paper Award 🙂

In this work, we looked at how to classify skin lesions from images captured with a digital camera (i.e., non-dermoscopy). Our approach was able to distinguish among 10 different types of skin diseases over 1300 images and achieved an accuracy higher than what was previously reported over the same dataset. We did this by applying deep learning (i.e., pretrained convolutional neural networks) to melanoma and non-melanoma skin images.
