"Human radiologists are already much worse than computer radiologists." I have a lot of respect for Sam Altman but he really hasn't done his homework on this one. cnbc.com/2019/02/26/sam…

Insisting that authors include a LIME/SHAP/IG/TCAV/GRADCAM saliency map in a paper shd be a disqualifying offense for reviewers. Including any such map without a powerful disclaimer (“this means nothing”) shd be a disqualifying offense for authors Extra true for ML in healthcare

Probably a watershed moment for diagnostic radiology. From a data structure/size standpoint, there is very little difference between a video and a CT/MRI. Buckle up

Excellent talk by Nathan Silberman from Butterfly Network on using GANs for domain adaptation. Largely solves the problem of heterogeneous data sources (i.e. different hospitals, vendors).

Was a lot of fun discussing the future of #AI in radiology with pioneering SIIM/Mass General Brigham Data Science Office (DSO) leader Katherine Andriole, Tarik Alkasab from Mass General Imaging, and Alex Bratt from @WeillCornellRad. Summarized by AuntMinnie.com here: auntminnie.com/index.aspx?sec…

Turns out it's possible to recreate training data from a NN using only black box api access--no need for params. Upshot for medical researchers and vendors is that if you train on unanonymized patient records, your model is PHI. arxiv.org/abs/1802.08232

Group develops machine learning model to predict future behavior of a chaotic system. Wonder how well it would do modeling other types of chaos (e.g financial markets, human behavior, physiology/pathology). Current DL seems poorly suited for these problems quantamagazine.org/machine-learni…
