Scientists Develop AI System That Can See What You Are Thinking

A group of Japanese computer scientists has developed a new AI system that can visualize human thoughts.

The technology can “see” the human thought or convert them into pictures. It’s always frightening to know that another person can read your thoughts. Imagine the case where technology can see what you are thinking!

How It Works – Functional MRI
 At the core of this technology lies the ability to scan the human brain. The scientists made use fMRI or Functional MRI to scan the brain over traditional MRI scan that can only monitor brain activity. fMRI, on the contrary, can track blood flow in the brain and even brain waves.

The system uses this data obtained from the scan to decide what the subject has been thinking. The resultant data is converted to image format, which is made possible by sending the data through a complex neural network that does the actual decoding.

But this technology couldn’t just grasp everything from the get-go. The machine has to be trained first to learn how the human brain works. It has to get used to tracking the blood flow.

Once the machine gets hold of the process, it begins projecting images that have a stark resemblance to what the subject was thinking. This was made possible only through employing multiple layers of DNN or Deep neural networks.

When DNN is tasked with processing the images, a DGN or Deep Generator Network is used to create images with more precision and accuracy. The differences in image creation with and without the DGN are vastly different.

The method of testing involves two steps. Firstly, the subject is shown an image, and then, the AI is made to recreate the images. The next part of the procedure makes the subject to visualize images in his/her mind. After which, AI system recreates the images in real time.
