Abstract: Training neural networks to recognize matching items requires large data sets and long training times. Conversely, training a neural network with triplets of similar objects instead of triplets of identical objects relaxes constraints on the size and content of the data set, making training easier. Moreover, the notion of “similarity” can be almost arbitrary, making it possible to train the neural network to associate objects that aren't visually similar. For instance, the neural network can be trained to associate a suit with a tie, which is not possible with training on identical objects. And because the neural network is trained to recognize similar items, it can also recognize unfamiliar items if they are similar enough to the training data. This is a technical improvement over other neural networks, which can only recognize identical items, and over collaborative filtering systems, which can only recognize items for which they have enough data.

Abstract: Shoppable video enables a viewer to identify and buy items appearing in a video. To retrieve information about the items in a frame of the video, the playback device generates a perceptual hash of that frame and uses that hash to query a first database storing perceptual hashes of different version of the video. The database query returns an identifier for the frame, which is then used to query a second database that store the item information. The results of this query are returned to the playback device, which shows them to the user, enabling the viewer to learn more about and possibly purchase the item. Using queries based on perceptual hashes of different versions of the video increases the likelihood of returning a match, despite formatting differences. And using separate hash and metadata databases makes it possible to update the metadata without changing the hashes.
