On the first level, several models are trained on the dataset; on the second level a high-level model combines the first level models in an optimal way.
Since such model is at first unknown, several models need to be tested in order to select the most appropriate one according to an arbitrary statistical index, commonly the standard error of fit.
We first developed several models of R. sphaeroides chemotaxis corresponding to different signalling networks, all of which are biologically plausible.
First, several PSF modeling with different principles are provided by vendors.
First, several SE competency models are presented.
First, several knockout animal models of IBD in a germ-free environment fail to develop intestinal inflammation [2] [6].
First, several homogeneous and non-homogeneous models were fitted to the data set, using a Tamura 1992 model of substitution with a four classes Gamma + invariant distribution of rates across sites.
We first tested the fit of several models of evolution for both characters.
In the proposed method, we initialize the background model with the first several frames and update only the sparse coefficients of the image patches that are distinguished as background.
The second recall includes 280,000 units across several models of the luxury Lexus brand overseas, mostly in the United States, as well as 75,000 units of the Crown, Mark X and Lexus brands in Japan.
