The relational model is based on the PMI-IR of two products, while the hierarchy model based on the category on the JD.com.
First, history of previous HIV testing based on transmission category and type of diagnosis was imputed; at the same stage, conditionally on a previous imputed negative test, time delay between the two tests was imputed using a linear regression model based on transmission category and type of diagnosis as described above and 5 datasets were generated.
Of the two sub-categories of model based methods, the explicit model-based methods are by far more popular, while there are only a few research articles in the alternative implicit methods.
First, we present a fine-grained activation threshold model based on the five categories of adopters.
The explorative unsupervised method (PCA) used for the whole data did not give clear group separation (data not shown), while the OPLS-DA model based on treated vs. untreated category as discriminating class (Fig. 3) produced a good descriptive but weak predictive model [one predictive and four orthogonal components give R 2 X (cum) = 0.82, R 2 Y (cum) = 0.60, and Q 2 (cum) = 0.24].
The high risk category in the model based on folic acid had a 2.2-fold (1.0 to 5.0) increased risk of cardiovascular mortality compared with the low risk category.
The features in the breast ultrasound images can be divided into four categories; Texture, Morphology, Model based and Descriptor [30].
This is true of all complexity measures in this category (randomness finding, nonprobabilistic, model based, [ 73]).
Among-site variation was included in the model, based on a gamma distribution with four categories.
Clustering algorithms are categorized into five major categories namely, Partitioning techniques, Hierarchical techniques, Density Based techniques, Grid Based techniques and Model based techniques.
According to the type of data a prediction model is based on, we can classify existing models into two categories: models based on historical traffic data and models based on real-time traffic data.
