Amazon does have the technology to recommend items without customers having bought them in the past. They use product viewing history to do this.

In a new store such as Amazon's Apparal section, they don't have the transaction history OR the product viewing history, so they can't accurately recommend products to viewers.

I agreee that maybe they shouldn't be recommending products at all if they have no basis for their recommendations, but their patent doesn't conflict with their policy on Amazon Apparals. Basically, their patent is to allow them to recommend products to customers who haven't BOUGHT anything, but have just browsed through the store enough.

I don't think I'm special in this respect, but I didn't find the example clips that were given too hard to discern.

Look for enunciation of certain latters such as P and M, and you should be able to tell the difference. The generated image gives a sense of moving the mouth but not enunciating the words clearly. Almost as if she is gliding over the words. With the real movie, however, you can see the woman completely changing her mouth formation to form the sounds required to pronounce the words.
