The problem of poor data quality is prevalent across multiple domains. A quantitative presence of noise in a given dataset is often reflective of the quality of the data. Data noise is generally categorized into two groups: mislabeling errors (class noise) and attribute noise. In the literature, noise detection techniques such as ensemble filter,(More)
Review spamming is quite common on many online shopping platforms like Amazon. Previous attempts for fake review and spammer detection use features of reviewer behavior, rating, and review content. However, to the best of our knowledge, there is no work capable of detecting fake reviews and review spammers at the same time. In this paper, we propose an(More)
In the case when resources allocated for software quality improvement are limited or unknown, an estimation of the relative rank-order of modules based on a quality factor such as number of faults is of practical importance to the software quality assurance team. This is because improvements can be targeted toward a set of most faulty modules according to(More)
This paper addresses automatic inpainting of a specific but common kind of videos captured by imaging a far or planar scene with a moving camera. The projective model tells that the frames of such videos can be approximately aligned by linear mappings except for some to-be-inpainted small regions. Mathematically, we treat inpainting as a global optimization(More)
