摘要:
Embodiments of the subject matter can facilitate classification by leveraging proximity in space, time, and relationships. Embodiments of the subject matter can be applied to data structures including but not limited to one dimensional arrays such as an audio signals, words, and DNA sequences; two dimensional arrays such as images; three dimensional arrays such as videos or volumetric images, higher-dimensional arrays such as volumetric videos; and graphs with nodes and edges such as in chemical structures. Embodiments of the subject matter have several advantages. First, they can result in greater classification accuracy because they can leverage proximity. Second, these embodiments are more efficient and don't require as much training time because they don't require backpropagation to update parameters. Third, they can't easily be fooled by the injection of spurious information and won't easily see patterns where there are none because they don't use unsupervised learning. Fourth, they can easily be parallelized over the number of features and over the number of training examples. Fifth, these embodiments can also be generative. For example, they can be used to generate an image given a classification such as a caption.

摘要:
Methods, systems, and apparatus for predicting the characteristics of a user are described. A model based on a conditional multivariate normal distribution and social relationship information between the selected user and each of one or more other users are obtained. One or more characteristics of the selected user are determined based on the model and the social relationship information. The user characteristics may be determined by adjusting the characteristics of a typical source user according to the model and the social relationship information of the selected user.
