Very interesting post for machine learning!

I have a question, how many images for training is enough to recognize a class as a human common sense level? Arnoud Buzing used about 10 images for each class, Bernat Espigulé Pons use about 100 images. So 100 images is good enough as minimal training level?

Nice examples!

Could we automate the image import from Bing or similar, and just leave the computer learning unattended? Even better, with some kind of topic evolution, by following the most common nouns from a zoo page or similar?

I'm conscious that we are still far from having a common pc capable of navigating the internet, learning all sorts of things as it/he/she goes... But I would love to see an example of what can already be done, even if limiting to a set of nouns from a dictionary, or starting from that... and obviously, with Mathematica!
