The goal of my app is to educate patients so that they recognise that they need to take further action. Regarding AI-assisted skin cancer diagnosis: This is a huge area that started with the publication of Esteva et al (https://www.nature.com/articles/nature21056) and there have been hundreds of publications since. There are large publicly available datasets that anyone can work with (https://challenge.isic-archive.com/). My lab has previously trained / evaluated convnets for diagnosis of skin cancer e.g. see this publication: https://pubmed.ncbi.nlm.nih.gov/32931808/ I have no doubt that it will be possible to train an AI model to perform at the same level as a…

dermatologist and AI models will become increasingly relevant. The main challenge at the moment is navigating uncertainty / liability since a very small proportion of moles / skin lesions that appear entirely harmless both the naked eye and with the dermatoscope (skin microscope) are cancerous.

Machine learning has been used for more than two decades in ATMs to perform optical character recognitions for automatic processing of checks [1]. I believe it is used by the post office as well. It is used by PayPal and other financial services companies for the purposes of fraud detection [2]. It is widely used to filter spam emails as well [3]. It is also widely used in recommender systems, starting with Netflix movie recommendations [4]. While currently more academic, it also has tremendous promise in healthcare diagnostic tasks [5,6]. It has also been used in economics applications such as measuring the global impact of fishing [7] and in poverty prediction in third…

This post doesn't even mention the easiest way to use deep learning without a lot of data: download a pretrained model and fine-tune the last few layers on your small dataset. In many domains (like image classification, the task in this blog post) fine-tuning works extremely well, because the pretrained model has learned generic features in the early layers that are useful for many datasets, not just the one trained on. Even the best skin cancer classifier [1] was pretrained on ImageNet. [1]: http://www.nature.com/articles/nature21056
