Image Recognition
In recent groundbreaking studies, researchers have proved that it is possible to use machine learning algorithms to reconstruct a person’s visual experiences from their brain activity. Brain activity measured by functional Magnetic Resonance Imaging (fMRI) is not the expected input for existing generative models. Moreover, when working with fMRI data, the number of available samples is quite small — far smaller than is needed to produce a model that performs with acceptable accuracy. This yields an image that coarsely represents the fMRI data. But the idea of reconstructing the private visual experiences of an individual also comes with some serious implications for privacy.
