Predicting e-book ranking based on the implicit user feedback

In this paper, we plan to predict a ranking on e-books by analyzing the implicit user behavior, and the goal of our work is to optimize the ranking results to be close to that of the ground truth ranking where e-books are ordered by their corresponding ...

article
Deep adversarial metric learning for cross-modal retrieval

Cross-modal retrieval has become a highlighted research topic, to provide flexible retrieval experience across multimedia data such as image, video, text and audio. The core of existing cross-modal retrieval approaches is to narrow down the gap between ...

Abnormal event detection in tourism video based on salient spatio-temporal features and sparse combination learning

With the booming development of tourism, travel security problems are becoming more and more prominent. Congestion, stampedes, fights and other tourism emergency events occurred frequently, which should be a wake-up call for tourism security. Therefore, ...

article
Co-regularized kernel ensemble regression

In this paper, co-regularized kernel ensemble regression scheme is brought forward. In the scheme, multiple kernel regressors are absorbed into a unified ensemble regression framework simultaneously and co-regularized by minimizing total loss of ...

article
Exploiting long-term temporal dynamics for video captioning

Automatically describing videos with natural language is a fundamental challenge for computer vision and natural language processing. Recently, progress in this problem has been achieved through two steps: 1) employing 2-D and/or 3-D Convolutional ...

article
Context-aware graph pattern based top-k designated nodes finding in social graphs

Graph Pattern Matching (GPM) plays a significant role in many real applications, where many applications often need to find Top-K matches of a specific node, (named as the designated node vd) based on a pattern graph, rather than the entire set of ...

article
Global-view hashing: harnessing global relations in near-duplicate video retrieval

Multi-view features are often used in video hashing for near-duplicate video retrieval because of their mutual assistance and complementarity. However, most methods only consider the local available information in multiple features, such as individual ...

article
Dilated-aware discriminative correlation filter for visual tracking

Recent progress has witnessed continued attention in discriminative correlation filter (DCF) tracking algorithms due to its high-efficiency. However, the existing DCF inevitably introduces some cyclic repetitions in learning and detection, which might ...
