The proposed framework is based on the minimax concave (MC) loss, which is a weakly convex function ... We show the conditions to guarantee convexity of the local and global objectives. Via ...

Convexity is a measurement of the degree of the curve plotted on a graph that demonstrates the relationship between bond prices and bond yield. What Is Convexity? Convexity is the curvature in the ...

Bonds can offer fixed income but their values on the secondary market can fluctuate. Bond convexity measures price sensitivity to interest rate changes, impacting value. Understanding convexity ...

Although I also see convexity in Metalla's share price today, I consider that Metalla had a concave payoff not too long ago. The expectations were high, the portfolio encountered issues ...

"That's where the HPC the high base convexity version steps in. It just better conforms to the concave shape of the integral heat spreader with full island pressure to get better performance out ...

Conclusions: Increased SWS of PSM without change of CST was observed on the concave side of the major curve in participants ... The t test was used to study the difference in SWS and CST between the ...

Abstract: This paper studies the projected saddle-point dynamics associated to a convex-concave function, which we term saddle function. The dynamics consists of gradient descent of the saddle ...

leading to concomitant formation of concavity and convexity of the crystal facets. We denote the respective ellipsoidal nanoplates as convex or concave oblate spheroids. Various types of six-fold ...
