Iterative regularization for learning with convex loss functions
No full textWe 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

Complete solo piano works of Zhou Long
No full textAccess to thesis restricted until 07/2023.Zhou Long is a contemporary composer of Chinese American descent, who
belongs to a generation of Chinese composers that began introducing traditional
Chinese music to western audiences. He gained international recognition after
receiving the 2011 Pulitzer Prize for his opera, Madame White Snake (2011). Very
few performances, recordings, and publications currently exist on Zhou’s piano
music, and this doctoral lecture recital is the first time an artist has performed the
complete collection of Zhou’s solo piano pieces. The pieces include: Mongolian Folk-
Tune Variations, Wu Kui, Pianogongs, and Pianobells. In his piano music, Zhou
makes use of unconventional extended piano techniques, imitates and evokes Chinese
traditional instruments, and likes to make connections with other art genres. Also, the
prominence of percussive elements in Zhou’s music is of a great importance. In this
lecture recital, the author has mainly focused on 1) the background information of
Zhou Long and his solo piano works; 2) the influence of Chinese traditional
instruments, ancient literatures and aesthetic concepts, in addition to folk elements on
his piano music; 3) how the composer combined those elements with western music
and compositional skills; and 4) the exploration of the percussive usage of the piano
along with various sound effect. Much of the discussion were from the author’s own
observations; it also include insights from an interview the author conducted with the
composer. Through the combined presentation of the lecture and performance of Zhou
Long’s four piano pieces, the author intended to help bring exposure to his piano
works, and to serve as a guide for piano students and teachers interested in exploring
Zhou’s piano music.Thesis (D.A.

An Analysis of <i>Judge Lin</i>
No full textBiography of Lin Wen Zhong Gong has another way to call, that is Judge Lin. The leading character is Lin Ze-Xu. This book is based on functionary experience of Lin Ze-Xu, with the captivating plots of court case, helping by highly skilled military attach\uc3\ua9s and chivalrous knights, and the history facts of Opium War. It makes Lin Ze-Xu\ue2s Confucian temperament and tragic mood more, also contrasts with author\ue2s sorrow and furiousness for the politics at the time. History, court case, martial arts\ue2\ua6\ue2\ua6etc. are essence of this book and it broadens the way of this writing style.
The topic of the thesis is \ue2An Analysis of Judge Lin\ue2. The following thesis will be divided into six different chapters. The introduction is Chapter one of the thesis, which is including researching motive and purpose, literature review of predecessors, researching version by existing information, raising questions, choosing research methods and arranging chapters. In chapter Two, I discuss the study of characters of Lin Ze-Xu, also makes a deep analysis of author\u27s purpose of writing him. In chapter Three, I analyze supporting actors and actress. Meanwhile, I illustrate author\u27s purpose of writing supporting actress because the author had different manner to describe supporting actress. Moving to the Chapter Four, I mainly focus on the plots of Judge Lin, and organize cases of Lin Ze-Xu and his subordinates to understand features of cases. In Chapter Five, I represent the causes of Opium War. China and England had difference of opinions of opium. Therefore, it is easier to comprehend what the author\u27s purpose is. In the last chapter I summarize the main points of the preceding chapters and confirm particularity of Judge Lin

Dorsal surface of head and body brown, darker on body; dorsal surface of the tail yellowish grey with several transverse brown bands, while the regenerated tail dark brown; at the base of the tail, white inconsecutive V- or U-shaped arms stretching forward; dorsal surface of limbs brown similar to head with weak, dark mottling; faint, diffuse dark stripe on lateral head, from the posterior corner of the orbit to neck, edged above by a narrow white stripe; ventral surface of the head and limbs cream grey and the body light brown. Variation. Measurements and scalation characters of the paratypes are presented in Table 5 and Table 6. The scale counts vary among the type series: scales between supranasals 2 or 3; supralabials and infralabials 9–11; dorsal scale rows at midbody 13–15, and ventral scale rows at midbody 7–9; precloacal and femoral pores 0–20. Etymology. This specific epithet is derived from the name of Huishui County of China and is in reference to the type locality. Natural history. Huishui County is located in the central and southern part of Guizhou Province, with an average elevation of 1100 m. These specimens were collected in the evening on the walls of the village houses. Three female paratypes (NJNUh00852, NJNUh00854 and NJNUh00855) were gravid with two shelled eggs each. Distribution. The species is currently known only from Huishui County and Ziyun County in southern Guizhou Province, Southwest China (Fig. 3). Morphological comparisons. We compared the undescribed gecko species from southern Guizhou Province with selected members of the genus Hemiphyllodactylus based on examination of specimens and data obtained from the literature (Zhou et al. 1981 with English translation of Ota 1996; Zug 2010; Grismer et al. 2013, 2014; Nguyen et al. 2013, 2014; Ngo et al. 2014; Guo et al. 2015). Diagnostic characters separating this species from other nominal taxa of Hemiphyllodactylus are shown in Table 4. Hemiphyllodactylus huishuiensis sp. nov. differs from H. chiangmaiensis Grismer, Wood & Cota; H. jinpingensis; H. kiziriani Nguyen, Botov, Le, Nophaseud, Bonkowski & Ziegler; H. longlingensis Zhou & Liu; H. yunnanensis; H. zugi and H. changningensis Guo, Zhou, Yan & Li in having a maximum SVL of 51.2 mm vs. a SVL 17 dorsal scales, and from H. kiziriani and H. zugi additionally by having 7–9 vs.> 11 ventral scales. Hemiphyllodactylus huishuiensis sp. nov. has a lamellar hand formula of 3-4 - 4 - 4 or 4 - 4 / 5 - 5 - 4 which separates chiangmaiensis (3 - 3 - 3 - 3 or 3-4 - 3 - 3) and H. changningensis (3 - 3 / 4 - 3 / 4 - 3), and a lamellar foot formula of 4 - 4 / 5 - 5 - 4 / 5 which separates chiangmaiensis (3 - 3 - 3 - 3 or 3-4 - 4 - 4); H. jinpingensis (4 - 4 - 4 - 4) and H. changningensis (3 - 3 - 3 - 3 or 3-4 - 4 - 4). Subdigital lamellae on first finger/toe can further differentiate Hemiphyllodactylus huishuiensis sp. nov. from H. banaensis; H. jinpingensis; H. kiziriani; H. longlingensis; H. yunnanensis and H. zugi, 3 vs. 4–6. Hemiphyllodactylus huishuiensis sp. nov. can also be separated from H. banaensis; H. chiangmaiensis; H. kiziriani; H. longlingensis and H. zugi by having no light postorbital stripe. From H. dushanensis, Hemiphyllodactylus huishuiensis sp. nov. differs by the coloration of the dorsal surface of the body (brown with dark transverse stripes vs. unicolor light brown in H. dushanensis); having less subdigital lamellae on first finger (3 vs. 4–5 in H. dushanensis) and first toe (3 vs. 5–6 in H. dushanensis); less precloacal and femoral pores (usually <20 vs. 24–26 in H. dushanensis), and having dark postorbital stripe (vs. light postorbital stripe in H. dushanensis).Published as part of Yan, Jie, Lin, Yubo, Guo, Weibo, Li, Peng & Zhou, Kaiya, 2016, A new species of Hemiphyllodactylus Bleeker, 1860 (Squamata: Gekkonidae) from Guizhou, China, pp. 543-554 in Zootaxa 4117 (4) on pages 546-553, DOI: 10.11646/zootaxa.4117.4.6, http://zenodo.org/record/26592
