The advancement, according to the researchers, could aid efforts to improve AI and lead to new insights into brain function. Deep learning itself is an advanced machine learning technique that uses layered (hence “deep”) neural networks (neural nets) that are loosely modelled on the human brain. Then they used the model to decode fMRI data from the subjects to reconstruct the videos, even ones the model had never watched before. The model was able to accurately decode the fMRI data into specific image categories. Actual video images were then presented side-by-side with the computer’s interpretation of what the person’s brain saw based on fMRI data.
