Tagging images is an important task because many images on the web are unlabeled and have no semantic information. This new method allows an appropriate tag to be generated by an AI algorithm interpreting the EEG scan of a person's brain while they view an image. The person need only view the image for as little as 500 ms. Other current methods for generating tags include flat out paying people to do it manually, putting the task on Amazon Mechanical Turk, or using Google Image Labeler."

I used to work in an EEG lab, and I can tell you that those caps are pretty uncomfortable to wear. After they put them on, you stick these little needles into the leads and squirt conductive goop on your scalp. It takes a few cycles to rinse that stuff out too.
Smitty, we've come a long way from those caps. There are now "caps" that are essentially nets of elastic cord with plastic cups containing pieces of sponge in them, the electrodes embedded in the sponge. Dip it in mild salt water for conduction, shake it out so there's no drips running together bridging the electrode sites, and pull it on. I could get good signal on 128 channels in less than 10 minutes from the time they walked in to data collection start.
There is also a European company selling a similar get up, but the preamps are built into the cups on the net, making impedance matching irrelevant and signal balancing automatic on the fly. These are so stable that they can be used ambulatory.
And nobody ever has to get goop or glue stuck on/into them any more.
