    Machine learning is a form of artificial intelligence that allows computers to learn and make predictions without explicit programming. A common form, supervised learning, is a training set of labeled data that is fed to the machine learning model, and then the model identifies patterns and applies unlabeled data to make predictions.

    Building a computer vision application might require feeding the model 1000 pictures of animals, for example, each labeled with its species. The model then identifies patterns and labels new pictures with species names with variable rates of success depending on the quality and size of the training data as well as the design of the model itself.

    Machine learning and other forms of artificial intelligence are sparking advances in health care, from computer-aided diagnosis of radiology images to predictive modelling of 30-day readmissions. A lot of hype surrounds the term AI, but not all of it is hype. AlphaGo has already beaten the best human Go player, a feat considered impossible just seven years ago because there are more possible Go moves than atoms in the universe.

    Machine learning has myriad potential applications in emergency medicine: Predictive modeling of patient arrivals, readmission likelihood, risk of complications, and nonpayment of bills are all obvious applications.

    Once you are ready to build your first predictive algorithm, try This site built a well-annotated platform that allows non-coders to input their training data quickly and easily, experiment with different machine learning algorithms, review the results, and then deploy a model. Their tutorials are extensive and fun to use. Best of all, their free version is good for up to 10,000 rows of data. I'm excited to see what you all build! Let me know at
