This study therefore tested the primary hypothesis improves in elderly patients. Methods article presents a follow-up of patients enrolled previous trial conducte...

We introduce and study minimax curriculum learning (MCL), a new method for adaptively selecting a sequence of training subsets for a succession of stages in machine learning. The subsets are encouraged to be small and diverse early on, and then larger, harder, and allowably more homogeneous in later stages. At each stage, model weights and training sets are chosen by solving a joint continuous-...

background applying an appropriate method of analgesia in labor without alteration in its progression is of high importance. previous literature did not provide much information about the effect of various kinds of anesthesia on the duration of active phase of labor. objectives to assess the effect of painless labor methods on the duration of active phase of labor. patients and methods 80 pregn...
