Evaluating deep transfer learning for whole-brain cognitive decoding

1 code implementation1 Nov 2021 Armin W. Thomas, Ulman Lindenberger, Wojciech Samek, Klaus-Robert Müller

Here, we systematically evaluate TL for the application of DL models to the decoding of cognitive states (e. g., viewing images of faces or houses) from whole-brain functional Magnetic Resonance Imaging (fMRI) data.

Challenges for cognitive decoding using deep learning methods

no code implementations16 Aug 2021 Armin W. Thomas, Christopher Ré, Russell A. Poldrack

In cognitive decoding, researchers aim to characterize a brain region's representations by identifying the cognitive states (e. g., accepting/rejecting a gamble) that can be identified from the region's activity.

AI is undergoing a paradigm shift with the rise of models (e. g., BERT, DALL-E, GPT-3) that are trained on broad data at scale and are adaptable to a wide range of downstream tasks.

Deep Transfer Learning For Whole-Brain fMRI Analyses

no code implementations2 Jul 2019 Armin W. Thomas, Klaus-Robert Müller, Wojciech Samek

Even further, the pre-trained DL model variant is already able to correctly decode 67. 51% of the cognitive states from a test dataset with 100 individuals, when fine-tuned on a dataset of the size of only three subjects.

Analyzing Neuroimaging Data Through Recurrent Deep Learning Models

1 code implementation23 Oct 2018 Armin W. Thomas, Hauke R. Heekeren, Klaus-Robert Müller, Wojciech Samek

We further demonstrate DeepLight's ability to study the fine-grained temporo-spatial variability of brain activity over sequences of single fMRI samples.
