  This manuscript describes our participation in the International Skin Imaging
Collaboration's 2017 Skin Lesion Analysis Towards Melanoma Detection
competition. We participated in Part 3: Lesion Classification. The two stated
goals of this binary image classification challenge were to distinguish between
(a) melanoma and (b) nevus and seborrheic keratosis, followed by distinguishing
between (a) seborrheic keratosis and (b) nevus and melanoma. We chose a deep
neural network approach with a transfer learning strategy, using a pre-trained
Inception V3 network as both a feature extractor to provide input for a
multi-layer perceptron as well as fine-tuning an augmented Inception network.
This approach yielded validation set AUC's of 0.84 on the second task and 0.76
on the first task, for an average AUC of 0.80. We joined the competition
unfortunately late, and we look forward to improving on these results.
