Commonly used 'random split' partitioning might lead to an overly optimistic performance estimate.
67 Validation with the same participants used to develop a model results in overly optimistic performance.
This procedure was used to assess the generalization error of a PDM-based classifier to avoid overly optimistic performance estimates [ 52, 53].
We therefore demonstrate that results of literature presented without taking into account PDYN,BB lead to optimistic performance.
We use the same hardware cost model of multicore chips used by Hill and Marty, but achieve very different and more optimistic performance models.
Results of last experimental campaign carried on in December 2004 revealed that all helium distributing cartridge options demonstrate optimistic performance (as compared to CFD simulations) and capability to transfer 10 25 MW/m2 in the helium mass flow rate (MFR) range of 5 15 g/s.
This method for selection of C for mi-SVM can potentially lead to over optimistic performance estimates.
Overall, for the data studied here, nonhierarchical models tended to yield optimistic performance assessments compared to assessments based on real data.
The independent validation results also showed that internal 10 × 5-CV and LPO bootstrap both yielded reasonably good and only slightly optimistic performance estimates for all the endpoints.
Because prediction models commonly show overly optimistic performance (i.e., overfitting) the c-index was computed with bootstrap sampling using the Design library in S-PLUS.
