The ability to extract frequent pairs from a set of baskets (or frequent word co-occurrences from a set of documents) is one of the fundamental building blocks of data mining. When the number of items in a given basket is relatively small the problem is trivial. Even when dealing with ...
Species co-occurrences in local communities can arise independent or dependent on species’ niches. However, the role of niche-dependent processes has
为了研究News Co-Occurrences与投资者关注度之间的关系,作者采用了两个模型,等式6和7的区别是,等式6中News Co-Occurrences直接用LNTF表示。等式7中,News Co-Occurrences用两个变量LNTFP和LNTFR表示,它们各自有自己的回归系数,这样做就可以看出是LNTFP更重要还是LNTFR更重要。 下表3给出了以上两个模型的回归结果,...
Then we propose to analyze the spatial co-occurrences between the adapted features to compute the image indices. Experimental tests on a public image database show the efficiency of this approach in the context of object recognition across illumination changes....
The method creates semantically classified temporal patterns, using word co-occurrences obtained from training corpora and a pre-defined seed keywords set, derived from the used language temporal references. A participation on a Portuguese named entity evaluation contest showed promising effectiveness and ...

Co-occurrences of putative endogenous retrovirus-associated diseasesBiotechnologyAt least 8% of the human genome is composed of endogenous retrovirus (ERV) sequences. ERVs play a role in placental morphogenesis and can sometimes protect the host against exogenous viruses. On the other hand, ERV ...
Here, we approach the EC phenomenon from a different perspective and ask: When do people learn evaluations from co-occurrences of two stimuli? This question has garnered much less interest compared to the how question, although it is one of the earliest puzzles faced by EC researchers: if ...
We performed co-occurrence analyses to determine the pairwise genera that had positive and negative co-occurrences, defined as genera that were positively or negatively associated more frequently than would be expected by chance. The co-occurrence analyses were binned by collection periods (0–11),...
