Tensor-based anomaly detection: An interdisciplinary survey

Hadi Fanaee-T, João Gama
2016 Knowledge-Based Systems  
However, if data includes tensor (multiway) structure (e.g. space-time-measurements), some meaningful anomalies may remain invisible with these methods.  ...  Traditional spectral-based methods such as PCA are popular for anomaly detection in a variety of problems and domains.  ...  (KL) divergence instead of common ALS fitting algorithm in PARAFAC.  ...

Theta phase coding in a network model of the entorhinal cortex layer II with entorhinal-hippocampal loop connections

Jun Igarashi, Hatsuo Hayashi, Katsumi Tateno
2006 Cognitive Neurodynamics  
One approach for reducing number of support vectors is to formulate SVM with a non-convex loss function.  ...  The symmetric STDP rule that has LTD windows on both sides of the central LTP window prevented irrelevant enhancement of loop connections caused by noise in cooperation with loop connections having a larger  ...  Conclusion: We proposed a pixel-parallel anisotropic diffusion algorithm(DDA) for subjective contour generation.  ...

Tensor Completion Algorithms in Big Data Analytics [article]

Qingquan Song, Hancheng Ge, James Caverlee, Xia Hu
2018 arXiv   pre-print
We conclude with a discussion of key challenges and promising research directions in this community for future exploration.  ...  We characterize these advances from four perspectives: general tensor completion algorithms, tensor completion with auxiliary information (variety), scalable tensor completion algorithms (volume), and  ...  How to combine domain knowledge with tensor completion problems could be another promising future direction for exploitation and exploration.  ...

A cross-linguistic study on the phonetics of dorsal obstruents

Dipl Geng, Bernd Pompino-Marschall, Daniel Recasens
unpublished
Such designs can for example be helpful to test whether the phoneme inventory of a language leaves its traces in patterns of velar coarticulation.  ...  study of the three major -labial, alveolar and velar -places of articulation, the present dissertation aims at the addition of the palatal place of articulation in obstruent production and perception, with  ...  This less restricted algorithm, PARAFAC2, offers an attractive alternative, especially in difficult situations.  ...
