Prediction of melting points of a diverse chemical set using fuzzy regression tree
The classification and regression trees (CART) possess the advantage of being able to handlelarge data sets and yield readily interpretable models. In spite to these advantages, they are alsorecognized as highly unstable classifiers with respect to minor perturbations in the training data.In the other words methods present high variance. Fuzzy logic brings in an improvement in theseaspects due ...
متن کاملSOME POINTS ON CASIMIR FORCES
Casimir forces of massive ferrnionic Dirac fields are calculated for parallel plates geometry in spatial space with dimension d and imposing bag model boundary conditions. It is shown that in the range of ma>>l where m is mass of fields quanta and a is the separation distance of the plates, it is equal to massive bosonic fields Casimir force for each degree of freedom. We argue this equalit...
متن کاملPurity and Identification of Solids Using Melting Points
Class-obtained melting points were used to create a melting point diagram of naphthalene and biphenyl. The eutectic point was estimated by extrapolation to be at 45 mole percent naphthalene. Unknown “A” was determined to be benzophenone by mixed melting point method. Introduction Melting points are used to help determine the purity and identification of solids. A melting point is the temperatur...
متن کاملSome results on convergence and existence of best proximity points
In this paper, we introduce generalized cyclic φ-contraction maps in metric spaces and give some results of best proximity points of such mappings in the setting of a uniformly convex Banach space. Moreover, we obtain convergence and existence results of proximity points of the mappings on reflexive Banach spaces
