Mind-reading devices can now access your thoughts and dreams using AI | New Scientist, Sep 2018
"We can now decode dreams and recreate images of faces people have seen, and everyone from Facebook to Elon Musk wants a piece of this mind reading reality"

"From an fMRI brain scan, Liu’s AI can say which of a selection of 15 different things a person was viewing when the scan was taken. For example, if someone was looking at a picture of a face, the AI can detect patterns in their scan that convince it to say “face”. Other options include birds, aeroplanes and people exercising, and the AI can call the correct category 50 per cent of the time."

Jack Gallant, UC Berkely: "When shown brain scans of someone watching a different YouTube video, the AI was able to generate a new movie of what it thought the person was viewing. The results are eerie outlines of the original, but still recognisable."

"Yukiyasu Kamitani at Japan’s Advanced Telecommunications Research Institute first showed in 2013 that it is possible to train an AI to detect the content of someone’s dreams, describing each in basic terms such as whether there was a male or female character, the objects included and details about the overall scene. Kamitani’s system has an accuracy of about 60 per cent."

"However, one big drawback of EEG is that there is so much unwanted noise to contend with. "

"The progress using AI with fMRI is causing people to rethink what EEG might be capable of."
