Developers will need to specify how often these metrics should be re-evaluated to assess for drift. Ideally, evaluation of high-stakes clinical research models should be overseen by a neutral third party, such as a regulatory agency. While predictive modeling is an important and necessary task, the derivation of real-world evidence from real-world data (i.e., making causal inferences) remains a highly sought-after goal toward which ML offers some promise. Proposed techniques include optimal discriminant analysis, targeted maximum likelihood estimation, and ML-powered propensity score weighting . A particularly intriguing technique involves use of ML to enable counterfactual policy estimation, in which existing data can be used to make predictions about outcomes under circumstances that do not yet, or could not, exist .

An artificial neural network is modeled on the neurons in a biological brain. Artificial neurons are called nodes and are clustered together in multiple layers, operating in parallel. When an artificial neuron receives a numerical signal, it processes it and signals the other neurons connected to it. As in a human brain, neural reinforcement results in improved pattern recognition, expertise, and overall learning. Machine learning offers a variety of techniques and models you can choose based on your application, the size of data you’re processing, and the type of problem you want to solve. A successful deep learning application requires a very large amount of data to train the model, as well as GPUs, or graphics processing units, to rapidly process your data. Use classification if your data can be tagged, categorized, or separated into specific groups or classes.

Recently, an automated analysis of free-speech collected during in-person interviews resulted in the ability to predict transition to psychosis with perfect accuracy in a group of high-risk youths . Because the operational problems previously detailed can potentiate the philosophical tangles of ML use in clinical research, many of the ways to overcome these hurdles overlap.
