About NeuroMiner

Machine learning techniques are poised to become clinically useful methods that may be used for diagnosis, prognosis, and treatment decisions. Despite this, they are currently underutilised in medical studies and, even more in psychiatric research because most current tools require strong programming and computational engineering skills (e.g., scikit-learn, caret, Weka, nilearn). While there are some great tools that do not require programming experience (e.g., undefinedPRoNTo), these are often focused on making predictions from specific data domains such as neuroimaging data. This highlights a pressing need for user-friendly machine learning software that makes advanced methods available to clinical researchers from different fields aiming at collaboratively developing diagnostic, predictive, and prognostic tools for precision medicine approaches.


NeuroMiner has been continuously developed by Nikolaos Koutsouleris since 2009 (with support from the European Commission for the PRONIA project since 2013) to provide clinical researchers with cutting-edge machine learning methods for the analysis of heterogeneous data domains, such as clinical and neurocognitive read-outs, structural and functional neuroimaging data, and genetic information. The program can be considered as an interface to a large variety of unsupervised, and supervised pattern recognition algorithms that have been developed in the machine learning field over the last decades. Furthermore, the application implements itself different strategies for preprocessing, filtering and fusing heterogeneous data, training ensembles of predictors and visualizing and testing the significance of the computed predictive patterns. The current release candidate of NeuroMiner has been tested in the Section of Neurodiagnostic Applications on a variety of datasets from healthy controls and patients with psychiatric disorders and was designed specifically to create robust models with a high probability of generalization to new datasets. For reference, we include here a undefinedlist of papers, which were all based on previous versions of the program.


More specifically, using a light-weight and interactive text-based menu system, NeuroMiner allows the user to:

  1. load their data easily (e.g., using spreadsheets, NifTi images, or SPM structures);
  2. build a variety of cross-validation frameworks for classification and regression problems that have become a gold standard in the field (e.g., repeated nested cross-validation, leave-site-out cross-validation);
  3. apply a range of preprocessing strategies (e.g., scaling, filtering, many forms of dimensionality reduction, etc.);
  4. choose and combine cutting-edge supervised algorithms (e.g., support vector machine, elastic net, random forest, etc.);
  5. apply feature selection procedures (e.g., wrappers), data fusion techniques, and stacked generalization;
  6. apply learned models to new data (external validation). 


To assist in selecting and analysing data, the user can visualise the data during input, monitor accuracy during learning, and understand the results of complex analyses using multiple display options. These allow the user to accurately report the data and also to understand the underlying machine learning analyses. Furthermore, the ability to apply the learned models to completely new data is important because it is quickly becoming a standard requirement of all machine learning studies. Combined, NeuroMiner gives the user the opportunity to design, implement, understand, and report machine learning analyses.
