Machine learning for every man and his dog

Research by a team from Eötvös Loránd University in Hungary has used machine learning techniques to classify dog barks - differentiating the message (stranger, angry, etc.) and the individual dog. (Source: Science Daily)

This is awesome! Of course you could use this to detect potentially dangerous situations, or even for automatic dog training, but by far the best idea is to give your dog their own bark-operated doggie door that would operated only for their bark. Just the thing for teasing the neighbour's bigger dog then hiding safely behind the secure electronic security only dreamed about in the days of Looney Tunes!
