AI & ML Research
Researchers at MIT have developed a mind-reading AI that can reconstruct images a person is viewing from their brain scans. The tool, detailed in a new paper, uses functional MRI data to decode visual perception with surprising accuracy. Meanwhile, a new analysis of the ReLU activation function argues that its success was never a biological commitment but a working hypothesis, challenging assumptions about neural network design. On the engineering side, a practical critique of cloud AI costs warns that companies are paying twice for inference—once for the model and once for the infrastructure—suggesting a shift toward local or edge deployment. Finally, MIT Technology Review's daily newsletter highlights both the mind-reading breakthrough and progress on tiny batteries for wearable AI devices.
