One of its versions, J48 [78], adds some extra features, such as pruning trees of less value and derivation of rules, thus reducing the impurity of data. This study J48 was used at the end of CNN's pipeline, and the parameter of this CNN was tuned using MOEPO. The proposed method ...
As shown, we also adopt a binary tree to maintain the keys which are generated by the hash-based derivation manner. In our scheme, the key update is in-situ, and the update complexity is \(O(\log n)\), which can reduce the computation and communication overheads as much as possible....
GSP derivation In the domain of agricultural scenic photography, numerous objects or fragments thereof are visible within each image. Research in biological and psychological fields indicates that human observation typically concentrates on a few objects that are visually or semantically distinct within thei...
The optimization of the LoR, DT, NBC, KNN and SVM models consisted in an automatic backward feature selection combined with a grid search of combination of hyperparameters. In practice, starting from all the 18 features, the feature selection function sequentially removed every feature from the da...
The derivation, presented in Appendix 8-B, yields the following theorem. THEOREM 5 A necessary and sufficient condition for three binary random variables to be star-decomposable is that they satisfy the inequalities (8.23)pikpijpi≤pijk≤pikpijpi+σjσk(ρjk−ρijρik)for all i, j...
Remember that a virtual field must be defined prior to data retrieval. The ORM does not perform the actual computation, nor the derivation of results from another table. It is the database engine that does all the hard work.Seek and You Shall FindIf you have no need for record-by-record...
The gradient of the objective functional\(\hat{J}\left( \rho \right)\), with respect to the density function\(\rho\)that is necessary to perform the optimization can be calculated efficiently utilizing the adjoint approach (see13for a detailed derivation). The adjoint approach allows for the...
“candidate” features may be provided to the host machine40, for instance extracted, calculated, or otherwise derived offline. Derivation may be conducted, for example, as a function of the base power, frequency, displacement, and/or acoustic signals provided from the welding controller20and/or ...
Advantageously, the block division of check node processing units according to the various embodiments enables a computation of syndromes by blocks of syndromes, a block comprising one or more syndromes, allowing a significant reduction of the computational complexity involved in the computation of the ...
In accordance with one embodiment of the invention, new virtual base classes may be added only as non-leftmost bases, and thus provide non-virtual base access without degradation, provide for further derivation of the hierarchy without impacting RRBC, and provide single inheritance and leftmost path...
