  • Computational psychiatry is an emerging field that examines phenomena in mental illness using formal techniques from computational neuroscience, mathematical psychology and machine learning. These techniques can be used in a theory-driven manner to gain algorithmic insight into neural or cognitive processes and in a data-driven way to identify predictive and explanatory relationships in complex datasets. The approaches complement each other: theory-driven models can be used to infer mechanisms, and the resulting measurements can be used in data-driven approaches for prediction. Data-driven algorithms can be used to answer theory-driven questions and pose quantitative problems requiring theoretical analysis. Recent computational studies have successfully described and measured novel mechanisms in a range of disorders, and have identified novel predictors of treatment response. These methods hold the potential to improve identification of relevant clinical variables, and could be superior to classification based on traditional behavioral or neural data alone. However, these promising results have been slow to influence clinical practice or to improve patient outcomes.
