AutoLoc: Weakly-Supervised Temporal Action Localization in Untrimmed Videos
Temporal Action Localization (TAL) in untrimmed video is important for many applications. But it is very expensive to annotate the segment-level ground truth (action class and temporal boundary). This raises t...

Online Detection of Action Start in Untrimmed, Streaming Videos
We aim to tackle a novel task in action detection - Online Detection of Action Start (ODAS) in untrimmed, streaming videos. The goal of ODAS is to detect the start of an action instance, with high categorizati...

Building and Using a Knowledge Graph to Combat Human Trafficking
There is a huge amount of data spread across the web and stored in databases that we can use to build knowledge graphs. However, exploiting this data to build knowledge graphs is difficult due to the heterogen...

Discriminative Indexing for Probabilistic Image Patch Priors
Newly emerged probabilistic image patch priors, such as Expected Patch Log-Likelihood (EPLL), have shown excellent performance on image restoration tasks, especially deconvolution, due to its rich expressivene...

From Low-Cost Depth Sensors to CAD: Cross-Domain 3D Shape Retrieval via Regression Tree Fields
The recent advances of low-cost and mobile depth sensors dramatically extend the potential of 3D shape retrieval and analysis. While the traditional research of 3D retrieval mainly focused on searching by a ro...

Recognizing Complex Events in Videos by Learning Key Static-Dynamic Evidences
Complex events consist of various human interactions with different objects in diverse environments. The evidences needed to recognize events may occur in short time periods with variable lengths and can happe...

Accelerated Large Scale Optimization by Concomitant Hashing
Traditional locality-sensitive hashing (LSH) techniques aim to tackle the curse of explosive data scale by guaranteeing that similar samples are projected onto proximal hash buckets. Despite the success of LSH...

Semantic Concept Classification by Joint Semi-supervised Learning of Feature Subspaces and Support Vector Machines
The scarcity of labeled training data relative to the high-dimensionality multi-modal features is one of the major obstacles for semantic concept classification of images and videos. Semi-supervised learning l...

Murine Coronavirus 5′-End Genomic RNA Sequence Reveals Mechanism of Leader-Primed Transcription
Mouse hepatitis virus (MHV) contains a single-strand, positive-sense RNA genome which is transcribed in infected cells, first, into a full-length negative-strand RNA (Brayton et al., 1982; Lai et al., 1982) an...
