This paper instantly infers the gas consumption and pollution emission of vehicles traveling on a city's road network in a current time slot, using GPS trajectories from a sample of vehicles (e.g., taxicabs). The knowledge can be used to suggest cost-efficient driving routes as well as identifying r ...

In this paper, we propose a citywide and real-time model for estimating the travel time of any path (represented as a sequence of connected road segments) in real time in a city, based on the GPS trajectories of vehicles received in current time slots and over a period of history as well as map data ...

Urban computing is a process of acquisition, integration, and analysis of big and heterogeneous data generated by a diversity of sources in cities to tackle urban challenges, e.g. air pollution, energy consumption and traffic congestion. Urban computing connects unobtrusive and ubiquitous sensing te ...

Discriminative appearance features are effective for recognizing actions in a fixed
view, but generalize poorly to changes in viewpoint. We present a method for viewinvariant
action recognition based on sparse representations using a transferable dictionary
pair. A transferable dictionary pair consi ...

We present novel semi-supervised boosting algorithms that incrementally build linear combinations of weak classifiers through generic functional gradient descent using both labeled and unlabeled training data. Our approach is based on extending information regularization framework to boosting, beari ...

We introduce the problem of joint object class sequencing and trajectory triangulation (JOST), which is defined as the reconstruction of the motion path of a class of dynamic objects through a scene from an unordered set of images. We leverage standard object detection techinques to identify object ...

Entity navigation over Linked Data often follows semantic
links by using Linked Data browsers. With the increasing volume of
Linked Data, the rich and diverse links make it difficult for users to
traverse the link graph and find target entities. Besides, there is a necessity
for navigation parad ...
