Beyond Novelty Detection: Incongruent Events, When General and Specific Classifiers Disagree

Daphna Weinshall, Alon Zweig, Hynek Hermansky, Stefan Kombrink, Frank W. Ohl, Bach, Luc Van Gool, Fabian Nater, Tomas Pajdla, Michal Havlena, Misha Pavel
2012 IEEE Transactions on Pattern Analysis and Machine Intelligence  
Here we identify distinct types of unexpected events, focusing on 'incongruent events'when 'general level' and 'specific level' classifiers give conflicting predictions.  ...  We derive algorithms to detect incongruent events from different types of hierarchies, corresponding to class membership or part membership.  ...  New sub-class: a new object has been encountered, of some known generic type but unknown specifics.  ...

HeadlineStanceChecker: Exploiting summarization to detect headline disinformation

Robiert Sepúlveda-Torres, Marta Vicente, Estela Saquete, Elena Lloret, Manuel Palomar
2021 Journal of Web Semantics  
The novelty rests on the use of a two-stage classification architecture that uses summarization techniques to shape the input for both classifiers instead of directly passing the full news body text, thereby  ...  Hence, to contribute to the detection of mis-and disinformation, this paper proposes an approach (HeadlineStanceChecker) that determines the stance of a headline with respect to the body text to which  ...  Also, this paper is also based upon work from COST Action CA18231 ''Multi3Generation: Multi-task, Multilingual, Multi-modal Language Generation''.  ...

Computational Curiosity (A Book Draft) [article]

Qiong Wu
2015 arXiv   pre-print
Chapter 2 reviews the arousal theories of curiosity in psychology and summarizes a general two-step process model for computational curiosity.  ...  In Chapter 8 and Chapter 9, the generic computational model of curiosity is studied in two types of pedagogical agents. In Chapter 8, a curious peer learner is studied.  ...  Berlyne listed them as supplementary variables to novelty, which includes change, surprisingness, and incongruity.  ...

The Genomic Substrate for Adaptive Radiation: Copy Number Variation across 12 Tribes of African Cichlid Species

2019 Genome Biology and Evolution  
Gene duplication has the potential to generate substantial molecular substrate for the origin of evolutionary novelty.  ...  Although CNVEs are detected on all linkage groups, they tend to cluster in "hotspots" and are likely to contain and be flanked by transposable elements.  ...  Reed students, Jaclyn Calkins, Ginger Jui, Karl Menzel, and Jeff Hunter contributed to this project at early  ...
