Ooctonus Haliday (Hymenoptera: Mymaridae) contains four species in the Neotropical Region: O. clebschi Huber, sp. n., O. costaricensis Huber, sp. n., O. woolleyi Huber, sp. n., and O. zolnerowichi Huber, sp. n. Ooctonus costaricensis represents the furthest south Ooctonus has been recorded in the New World. An illustrated identification key to females is given. The genus is compared with Boudie...

The Huber function is an hybrid l1-l2 misfit measure. We demonstrate, on velocity analysis examples, that the Huber function is more robust to outlier effects, and more stable with respect to the number of iterations than the l2 norm. We also show that the Huber threshold which controls the transition between the l1 and the l2 norm may be chosen within a certain range of values without damaging...

The “Huber function” (or “Huber norm”) is one of several robust error measures which interpolates between smooth (l 2) treatment of small residuals and robust (l 1) treatment of large residuals. Since the Huber function is differentiable, it may be minimized reliably with a standard gradient-based optimizer. We propose to minimize the Huber function with a quasi-Newton method that has the poten...

This paper prewnts the robust kahnan based method which is modified with Huber function for estimating time varying WA under the imputsive noise. It is known that the performance of Kalman algorithm degradestiously when the input si~rds contain the impdsive noise. To reduce the effects of the impulsive noise, this algorithm emends the con~pt of Huber fiction to the Khan based estimator. Simulat...

Distributed data naturally arise in scenarios involving multiple sources of observations, each stored at a different location. Directly pooling all the together is often prohibited due to limited bandwidth and storage, or privacy protocols. A new robust distributed algorithm introduced for fitting linear regressions when are subject heavy-tailed and/or asymmetric errors with finite second momen...

Bakkendorfia Mathot, syn. n. is placed in synonymy under Cleruchus Enock and its only described species transferred as Cleruchus musangae (Mathot), comb. n.Anaphes quinquearticulatus Huber & Triapitsyn, sp. n. is described; it is the only known Anaphes Haliday species with a 5-segmented funicle in females. Two genera are reported for the first time from the Afrotropical region and two species a...
