Selective hidden random fields: Exploiting domain-specific saliency for event classification
TLDR
We propose to use the domain-specific saliency of the appearances of the playing surfaces, and ignore the noninformative parts of the image such as crowd regions, to discriminate among different sports. Expand

Adapting Classification Cascades to New Domains
TLDR
We present an algorithm for quickly adapting a pre-trained cascade of classifiers to perform well in data domains with variations in appearances that may not be captured in the training examples. Expand

Tracking the Conductance of Rapidly Evolving Topic-Subgraphs
TLDR
We propose an in-memory approximation called BloomGraphs to store and update these (possibly overlapping) evolving subgraphs in real-time with very small memory footprint. Expand

Mitigating Deafness in Multiple Beamforming Antennas
TLDR
In this paper, we provide a novel algorithm for mitigating deafness (AMD) in beamforming antennas by dynamically maintaining parameters for every beam. Expand

Short-text representation using diffusion wavelets
TLDR
We study a representation based on the multi-scale harmonic analysis of term-term co-occurrence graph to embed the terms in the corresponding vocabulary in a continuous Euclidean space. Expand

Min-d-Occur: Ensuring Future Occurrences in Streaming Sets
TLDR
We present an algorithm that provides a solution with the success probability of at least 1 - O (kd log n/D + 1/n), where D is a known constant. Expand
