Sentence examples for a best subset of from inspiring English sources

Instead of evaluating the similarity between individual features and class labels, wrapper methods seek for a best subset of features by evaluating the subset as a whole based on classification performance.

A best subset of models is usually created during an experiment.

We chose a "best subset" of these models on the basis of optimal error distributions for individual replicate models (34 ): median area predicted across all replicate modes was calculated, and the 20 models with predicted areas closest to the median were chosen for further consideration.

A best subset is a group of a user-defined number of models from an experiment that meet omission and commission criteria established by the user as a means of selecting those models that best balance between low omission and median commission values [78].

For example, the socio-demographic variables were entered into a regression model as a group and the best subset of them was identified using the purposeful selection methods proposed by Hosmer and Lemeshow [ 20].

Other element that distinguishes this work from others is that it is not proposed as an outlier detector but as an algorithm that determines the best subset of input vectors by the time of building a model to approximate it.

Practically, the best subset of a data set is first chosen and the genes in it are then listed for biological usage.

Unfortunately, if the number N of acquired features is high, an exhaustive search of the best subset of features may be impractical.

Although the approach used in the present paper does not ensure an exhaustive search of the best subset of independent predictors, it considers all local changes to the current set of features and makes an optimal selection.

For EGT, we consider the selection of the best subset of N a antennas (that results in the highest SNR) at the receiver, which exploits all the available transmit antennas and offers full transmit-diversity gains, and the random selection, which offers transmit-diversity gains equal to the number of active transmit antennas.

Third, a stepwise logistic regression was used to select the best subset of independent variables and compute a French ProVent score.
