The phrase "absence of classification" is correct and usable in written English.
It can be used in contexts discussing the lack of categorization or organization of information, data, or items.
Example: "The absence of classification in the dataset made it difficult to analyze the trends effectively."
Alternatives: "lack of categorization" or "nonexistence of classification".
Technology together with the absence of classification has caused problems in dealing with information particularly in the aspect of storage.
Other studies could show that speech listening automatically induces changes in articulatory movements, thus providing further arguments for causal functional links between the perception and articulation of speech sounds in the absence of classification tasks (Yuen et al. 2010; D'Ausilio et al. 2014).
Other limitations of the study are the absence of classification according to the type of ANCA (PR3 or MPO) and the lack of information about changes in the levels of ANCA, given that both of these have important prognostic implications [ 30, 31].
In this paper, we propose a method to predict the presence or absence of correct classification results in classification problems with many classes and the output of the classifier is provided in the form of a ranking list.
Guidelines for bioequivalence (BE) studies and GMP regulations applied for the development and manufacturing of generic products are similar to those in other countries, while the requirements [e.g., absence of biopharmaceutics classification system (BCS) biowaiver for new generic products] have some differences (Davit et al. 2013; MHLW 2012a).
In the absence of HOM classification, the results of the STR module prevail over the TSD module.
Moreover, sibling studies that prospectively track infants have been useful in elucidating early markers of not only the risk of future ASD diagnosis, but also the risk of discrete neuropsychological skill deficits in the absence of ASD classification.
The author stresses the paradox of the growing number of mental disorders versus the absence of a natural classification and then defines what a classification is, why it exists, how it is established, and what its evolution is like.
The most apparent difference is the absence of a biopharmaceutics classification system (BCS -based BCS -basedin the application of new generic products.
Another problem has been the lack of consensus regarding EEG terminology and the absence of a uniform classification system, a problem that may be resolved by implementation of a standardized critical care EEG-terminology as recently proposed [162].
In the absence of specific biomarkers, classification criteria are generally used to define study populations.
