HID: Hierarchical Multiscale Representation Learning for Information Diffusion

Honglu Zhou, Shuyuan Xu, Zuohui Fu, Gerard de Melo, Yongfeng Zhang, Mubbasir Kapadia
2020 Proceedings of the Twenty-Ninth International Joint Conference on Artificial Intelligence  
In this paper, we present a Hierarchical Information Diffusion (HID) framework by integrating user representation learning and multiscale modeling.  ...  The proposed framework can be layered on top of all information diffusion techniques that leverage user representations, so as to boost the predictive power and learning efficiency of the original technique  ...  MDP for the home team given the learned reward (cf.  ...

Scalable Bayesian reduced-order models for high-dimensional multiscale dynamical systems [article]

P.S. Koutsourelakis, Elias Bilionis
2010 arXiv   pre-print
While existing mathematical descriptions can accurately account for phenomena at microscopic scales (e.g. molecular dynamics), these are often high-dimensional, stochastic and their applicability over  ...  We discuss parallelizable, online inference and learning algorithms that employ Sequential Monte Carlo samplers and scale linearly with the dimensionality of the observed dynamics.  ...  A critical question that offers opportunity for future research on the topic relates to structural learning and in particularly with the dimensionality of the representation, i.e. the number of hid-den  ...

Natural Scene Text Understanding [chapter]

Celine Mancas, Bernard Gosseli
2007 Vision Systems: Segmentation and Pattern Recognition  
Multiscale representations through Gaussian pyramids are computed for A, A' and B' and at each level, statistics for every pixel in the target pair (B,B') are compared to every pixel in the source pair  ...  However, they use spatial information which groups text pixels efficiently. • Learning-based approaches have initially been designed to mimic humans by learning a training database to further recognize  ...  for RGB color space 3 : • RGB  ...
