The PAU Survey and <i>Euclid:</i> Improving broadband photometric redshifts with multi-task learning
Current and future imaging surveys require photometric redshifts (photo-zs) to be estimated for millions of galaxies. Improving the photo-z quality is a major challenge but needed advance our understanding cosmology. In this paper we explore how synergies between narrow-band data large can exploited improve broadband redshifts. We used multi-task learning (MTL) network estimates by simultaneous...
This paper is devoted to a study of interpolatory refinable functions. If a refinable function φ on Rs is continuous and fundamental, i.e., φ(0) = 1 and φ(α) = 0 for α ∈ Zs\{0}, then its corresponding mask b satisfies b(0) = 1 and b(2α) = 0 for all α ∈ Zs\{0}. Such a refinement mask is called an interpolatory mask. We establish the existence and uniqueness of interpolatory masks which are induc...
magnetic Electrons and a Classical Theory of Atomic Structure and Radiation," Mercury Press, Montreal. In the present note the classical views of Professor King are not adhered to. However, it may be that there is a connection between the two treatments. 1 Nature, February 20, 1926, p. 264. 2 Proc. Nat. Acad. Sci., 12, 1926, pp. 80-85. Zs.

through-plane concomitant field phase accrual, for a phantom (squares no correction, triangles corrected) and human brain (circles no correction, diamonds corrected). Dephasing from concomitant gradient fields leads to error in ADC that increases with distance from isocenter (zS = 10cm-superior; zS = 0cm-inferior). FIG 1. Diffusion gradient timing for StejskalTanner (ST; insensitive to concomit...
Consider a Martin-Löf random ∆2 set Z. We give lower bounds for the number of changes of Zs n for computable approximations of Z. We show that each nonempty Π 1 class has a low member Z with a computable approximation that changes only o(2) times. We prove that each superlow ML-random set already satisfies a stronger randomness notion called balanced randomness, which implies that for each comp...
