background: sperm selection is generally used to describe methods for separation of spermatozoa for in-vitro-assisted reproduction. few studies reported relation in vivo fertility and semen parameters after selection of fertile spermatozoa; hence, our research attempt to assess different semen parameters after post-thaw (pt) or after selecting sperm sample (ssp), using density gradient separati...

In this paper, we investigate accelerated first-order methods for smooth convex optimization problems under inexact information on the gradient of objective. The noise in is considered to be additive with two possibilities: absolute bounded by a constant, and relative proportional norm gradient. We accumulation errors strongly settings main difference most previous works being that feasible set...

This paper applies an idea of adaptive momentum for the nonlinear conjugate gradient to accelerate optimization problems in sparse recovery. Specifically, we consider two types minimization problems: a (single) differentiable function and sum non-smooth function. In first case, adopt fixed step size avoid traditional line search establish convergence analysis proposed algorithm quadratic proble...
