Scientists Create Artificial Intelligence That Turns Thought into Image
Researchers have discovered that they can reconstruct high-resolution images of brain activity. Artificial intelligence was used to create images obtained from brain waves.
What if an artificial intelligence could interpret your imagination and turn the images in your mind into reality? Although this may sound like a cyberpunk story, scientists have achieved exactly that in a new study. Researchers have discovered that they can create high-resolution and accurate images of brain activity.
As stated in an article published last December, high-resolution and highly accurate images of brain activity (fMRI signals) were created with the currently popular artificial intelligence imaging tool Stable Diffusion. The study’s authors also note that unlike previous studies, they did not need to train or fine-tune the AI models to create these images.
Stating that this study is a look at the internal processes of diffusion models, the researchers stated that the study is the first to provide a quantitative interpretation of the model from a biological perspective. For example, a diagram was created by the researchers that shows the correlation between stimuli and noise levels in the brain. The higher the stimuli, the higher the noise level. As a result, the image also becomes higher resolution.
In another diagram, the researchers even show how different neural networks in the brain come into play and remove noise to reconstruct an image. With the advancement of generative AI, more and more researchers are testing how AI models can work with the human brain. This study, on the other hand, can be considered as a preliminary research.
