    Iterative regularization for learning with convex loss functions

    No full text
    We consider the problem of supervised learning with convex loss functions and propose a new form of iterative regularization based on the subgradient method. Unlike other regularization approaches, in iterative regularization no constraint or penalization is considered, and generalization is achieved by (early) stopping an empirical iteration. We consider a nonparametric setting, in the framework of reproducing kernel Hilbert spaces, and prove consistency and finite sample bounds on the excess risk under general regularity conditions. Our study provides a new class of efficient regularized learning algorithms and gives insights on the interplay between statistics and optimization in machine learning. ©2016 Junhong Lin, Lorenzo Rosasco and Ding-Xuan Zhou

    The mitochondrial genome of Calohilara tibetensis Ding, He, Lin, and Yang, 2020 (Diptera: Empididae)

    The dance fly Calohilara tibetensis Ding, He, Lin and Yang, 2020 belongs to the subfamily Empidinae of Empididae. The mitochondrial genome of C. tibetensis was sequenced as the new representative of the subfamily Empidinae. The nearly complete mitogenome was 15,354 bp, consisting of 13 protein-coding genes, two rRNAs, and 22 tRNAs. All genes have the similar locations and strands with that of other published species of Empididae. The nucleotide composition biases toward A and T is 77.4% of the entirety. All PCGs start with ATN codons except COI and NAD1, and end with TAA or incomplete stop codon. Bayesian inference (BI) analysis strongly supported the monophyly of both Empididae and Dolichopodidae and the monophyly of subfamily Empidinae. It suggested that Calohilara is the sister group of Hilara
