We investigate numerical integration of ordinary differential equations (ODEs) for Hamiltonian Monte Carlo (HMC). High-quality integration is crucial for designing efficient and effective proposals for HMC. While the standard method is leapfrog (Stormer-Verlet) integration, we propose the use of an ...

We investigate the problem of generalized zero-shot learning (GZSL). GZSL relaxes the unrealistic assumption in conventional ZSL that test data belong only to unseen novel classes. In GZSL, test data might also come from seen classes and the labeling space is the union of both types of classes. We s ...

Given a quarter of petabyte click log data, how can we estimate the relevance of each URL for a given query? In this paper, we propose the Bayesian Browsing Model (BBM), a new modeling technique with following advantages:
(a) it does exact inference;
(b) it is single-pass and parallelizable;
(c) ...

Linear projection for reducing data dimensionality is a common practice in various
data processing applications. Among the existing projection methods, Principal Component
Analysis (PCA) is arguably the most popular one. Standard PCA used in image
preprocessing pursues the projection directions b ...

The Nyström method is an efficient approach to enabling large-scale kernel methods. The Nyström method generates a fast approximation to any large-scale symmetric positive semidefinete (SPSD) matrix using only a few columns of the SPSD matrix. However, since the Nyström approximation is low-rank, wh ...

Understanding human mobility is of great importance to various applications, such as urban planning, traffic scheduling, and location prediction. While there has been fruitful research on modeling human mobility using tracking data (e.g., GPS traces), the recent growth of geo-tagged social media (Ge ...

Recommendation and review sites offer a wealth of information beyond ratings. For instance, on IMDb users leave reviews, commenting on different aspects of a movie (e.g. actors, plot, visual effects), and expressing their sentiments (positive or negative) on these aspects in their reviews. This sugg ...
