neural nets

Speaking of neural nets and image recognition, my former employers landed a contract with "various law enforcement agencies" although the project manager I spoke to said primarily the FBI and CIA - to develop neural network hardware and software to do face recognition, to be used to identify criminals at the airports. Indeed, I recall being photographed twice when I hired on - normal lighting for my regular id, and low lighting. At the time, I wondered why but didn't think anything of it. The project manager said they were amassing a database of pictures to use as training sets. Pretty interesting...
