Abstract

Fully automated classification algorithms have been successfully applied to diagnose a wide range of neurological and psychiatric diseases. They are sufficiently robust to handle data from different scanners for many applications and in specific cases outperform radiologists. This article provides an overview of current applications taking structural imaging in Alzheimer's disease and schizophrenia as well as functional imaging to diagnose depression as examples. In this context, we also report studies aiming to predict the future course of the disease and the response to treatment for the individual. This has obvious clinical relevance but is also important for the design of treatment studies that may aim to include a cohort with a predicted fast disease progression to be more sensitive to detect treatment effects. In the second part, we present our own opinions on i) the role these classification methods can play in the clinical setting; ii) where their limitations are at the moment and iii) how those can be overcome. Specifically, we discuss strategies to deal with disease heterogeneity, diagnostic uncertainties, a probabilistic framework for classification and multi-class classification approaches.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Classifying participants using several measurements (e.g., fMRI data from few distinct VSWM tasks), where each measurement enables better than chance classification and there is substantial independency between measurements, enabled higher classification accuracies compared to using data from each single measurement.

    “As expected based on this theorem, classifying participants by using several measurements for each participant (e.g., fMRI data from few distinct VSWM tasks), where each measurement enables a better than chance classification accuracy, and where there is a substantial degree of independency between the measurements (e.g., distinct cognitive tasks), enabled higher classification accuracies compared”
  • The improvement in classification accuracy when using PCs from four tasks together is consistent with the underlying theorem of ensemble-based classification.

    “This is consistent with the underlying theorem of ensemble-based classification (Rokach, 2010; Klöppel et al., 2012).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
