À-la-carte Prompt Tuning (APT): Combining Distinct Data Via Composable Prompting
No full textWe introduce À-la-carte Prompt Tuning (APT), a transformer-based scheme to tune prompts on distinct data so that they can be arbitrarily composed at inference time. The individual prompts can be trained in isolation, possibly on different devices, at different times, and on different distributions or domains. Furthermore each prompt only contains information about the subset of data it was exposed to during training. During inference, models can be assembled based on arbitrary selections of data sources, which we call "à-la-carte learning". À-la-carte learning enables constructing bespoke models specific to each user's individual access rights and preferences. We can add or remove information from the model by simply adding or removing the corresponding prompts without retraining from scratch. We demonstrate that à-la-carte built models achieve accuracy within 5% of models trained on the union of the respective sources, with comparable cost in terms of training and inference time. For the continual learning benchmarks Split CIFAR-100 and CORe50, we achieve state-of-the-art performance
Species of Formica
No full textABSTRACT We revise the Nearctic endemic Formica pallidefulva group based on study of types and other museum specimens and material in J. Trager's collection. The latter material originates from 30 years of accumulated samples, both from free-living colonies of F. pallidefulva group species, and from "slave" populations in colonies of Polyergus lucidus s. l., which have single-species host populations. Among the currently available names for the group, the four valid taxa are F. archboldi, F. dolosa, F. incerta and F. pallidefulva. There is a fifth common, but previously unrecognized new species, described here as Formica biophilica Trager, n. sp. Earlier taxonomies of this group were constrained by typological thinking and inadequate treatment of metric characters. For this study, well preserved individuals, nest series and types of all but one taxon were studied (no types seen for F. pallidefulva). Analysis focused on form, length, abundance and distribution of macrochaetae (pilosity); length and density of microchaetae (pubescence); standard measurements and indices; distinct habitat preferences of the various species; and host selection by Polyergus lucidus, s. l. Our results leave little doubt that F. incerta n. stat., rev. stat. and F. biophilica n. sp. deserve recognition as species, that F. nitidiventris is a synonym of F. pallidefulva and that F. schaufussi is a synonym of F. pallidefulva. Thus, the current concept of schaufussi (incorrect in reference to the lectotype) must give way to the next available name for the same population, dolosa n. stat. In this paper, we provide diagnoses, qualitative morphological characteristics, tabulated quantitative characters, natural history notes for all species and a key to the workers. As occurs in other groups of closely related ant species (e.g

Caméras, formes et contours: modèles géométriques en vision par ordinateur
No full textThis thesis studies mathematical models for describing the geometry of imaging processes in computer vision. Our approach is rooted in the language of projective geometry, which provides the most general setting for studying properties of lines and incidences that are at the heart of geometric vision. We also apply some tools from algebraic geometry, since many of the objects that we encounter are described by polynomial equations. For example, the multi-view geometry of pinhole cameras (or in fact any type of cameras) can be encoded in the "joint image", that is an algebraic variety in formed by all point correspondences. The Grassmannian of lines also plays a central role in our study. In particular, surfaces in the Grassmannian (or "line congruences") can be used to represent abstract cameras, that are mappings from points to viewing lines. In addition to modeling cameras, we investigate the relationship between 3D shapes and their images. For arbitrary sets projecting onto opaque silhouettes, the image is determined by the set of viewing lines that meet the observed object; for smooth surfaces, the "image contour" is determined by the set viewing lines that are tangent to the surface. This perspective is applied to the study of "visual hulls" and "visual events".Cette thèse étudie les modèles mathématiques destinés à décrire la géométrie des processus d’imagerie en vision par ordinateur. Notre approche est enracinée dans le langage de la géométrie projective, qui fournit le cadre le plus général pour l’étude des propriétés des lignes et des incidences qui sont au cœur de la vision géométrique. Nous appliquons également des outils de la géométrie algébrique, car la plupart des objets que nous rencontrons sont décrits par des équations polynomiales. Par exemple, la géométrie de n caméras peut être encodée dans une variété algébrique en formée par les correspondances de points. La Grassmannienne des lignes joue également un rôle central dans notre étude. Les surfaces en (ou “congruences”) peuvent par example être utilisées pour représenter des caméras abstraites, qui associent des points à des lignes. Nous étudions aussi la relation entre les formes 3D et leurs images. En particulier, pour les ensembles arbitraires se projetant sur des silhouettes, l’image est déterminée par l’ensemble des lignes qui rencontrent l’objet observé ; pour les surfaces lisses, le “contour visuel” est déterminé par les lignes qui sont tangentes à la surface. Cette perspective est appliquée dans l’étude des "coques visuelles" et des "événements visuels"
Arithmetic properties of elliptic curves over finite fields
No full textIn this thesis, we give a brief survey on elliptic curves over finite fields, complex multiplication and isogeny volcanos. We then present a series of results that describe the possible orders and structures of the groups G_k=E(F_{q^k}), as k varies, assuming the curve E is defined over F_q. Several of these do not seem to appear in standard literature
Multigraded Cayley-Chow Forms
No full textWe introduce a theory of multigraded Cayley-Chow forms associated to subvarieties of products of projective spaces. Two new phenomena arise: first, the construction turns out to require certain inequalities on the dimensions of projections; and second, in positive characteristic the multigraded Cayley-Chow forms can have higher multiplicities. The theory also provides a natural framework for understanding multifocal tensors in computer vision
Gestational weight gain effect on delivery and neonatal outcomes
No full textKOPSAVILKUMS Virsraksts: Gestācijas svara pieauguma ietekme uz dzemdībām un jaundzimušo Mērķis: Grūtniecība var būt vissvarīgākais fizioloģiskais process dzīves ciklā. Pareiza barošana grūtniecības un pēcdzemdību periodā ir svarīga gan jaundzimušo, gan mātes veselībai. Šī pētījuma mērķis ir analizēt saistību starp grūsnības ķermeņa masas pieauguma rādītājiem dažādās vecuma grupās un novērtēt neonatāla rezultāta ietekmi uz abiem bērniem. Materiāli un metodes: materiāls tika savākts no 2017. gada oktobra līdz 2017. gada decembrim Rīgas Dzemdību nams. Mēs iekļāvām 306 sievietes ar normālu jebkura vecuma un grūtniecības ķermeņa svaru, piemēram, priekšlaicīgu dzemdību laiku, termiņu un pēcnāves laiku, primipara un multipara, izņemot divu dzimšanu un zināmus pirmsdzemdību endokrīnās sistēmas traucējumus. Avārijas C sekcijas un jaundzimušo skaits ar Apgar punktu skaitu pārsniedz 7 punktus, tiek analizēta trīs dažādu svara kategoriju sievietēm (zem ieteiktā svara, ieteicamā masa un virs), tās tālāk iedala 5 dažādās vecuma grupās, kuras analizē atsevišķi . Rezultāti: Lielākā daļa (69%) sieviešu ir ārpus ieteiktā svara parametra, no kuriem lielākā daļa (50%) pārsniedz ieteicamo svaru. Sievietes vecuma grupas visaugstākajā vecuma grupā (> 35 gadus veci) visbiežāk gūst virs rekomendētā ķermeņa masas grūtniecības laikā (79%), savukārt sievietēm 35 gadus vecus), kuri vairāk nekā ieteicamā ķermeņa masa ieguva grupu ar sliktākiem jaundzimušajiem (16%). Secinājumi: Latvijas sievietēm, kuras guvušas lielu gestācijas svaru, ir sliktāki piegādes rezultāti un negatīvi ietekmē jaundzimušo veselību. Jebkāda gestācijas svārstību novirze, kas pārsniedz ieteicamos parametrus, jāuzrauga un jākoriģē.

Proper nutrition in pregnancy and postpartum is important for both neonatal and maternal health. This study aims to analyze the association between rates of gestational weight gain in different age groups and to evaluate the impact on both the delivery a neonatal outcome. Methods: The material was collected between October 2017 and December 2017 in Rīgas Dzemdību Nams. We included 306 Women with a normal BMI of all ages and gestation types such as preterm, term and post term, primipara and multipara excluding twin-birth and a known pre-pregnancy endocrine disorders. The prevalence of emergency C-sections and neonates with an Apgar score bellow 7 points is analyzed in women of three different weight categories (below the recommended weight, recommended weight and above), they are further divided into 5 different age groups which are analyzed individually. Results: The majority (69%) of Women is outside the recommended weight parameter, of which the largest portion (50%) is above the recommended weight. Women on the highest end of the age spectrum (>35 years old) are most prone to gain above the recommended weight during gestation (79%) on the other end women women 35 years old) who gained more than the recommended weight the group with the worse neonatal outcomes (16%). Conclusions: Latvian women who gained excess gestational weight have worse delivery outcomes and negatively impacts neonatal health. Any gestational weight gain deviation above the recommended parameters should be monitored and corrected.

Moral Psychology and Support for the Use of Force in the International System
No full textWhy and under what circumstances do people support aggressive action in the international system? And can political psychology actually give us insights into state behavior? This dissertation argues against conventional accounts that hold that the public is rational and strategic with the regards to the use of power. Relying on the concepts of the cognitive miser and rational ignorance among the voting public, the author uses experimental methods to show that with regards to foreign policy individuals are motivated by the same prejudices and moral intuitions that guide domestic political behavior. The first chapter argues against folk realist theories and shows that constructivist theories based on the need to maintain a positive self-image do a better job of predicting when Americans support the use of force abroad. Another chapter shows that when Americans consider altruistic policies, hearing that the policy in question can financially benefit the United States makes them less likely to support it. Furthermore, the implications of differences between conservatives and liberals are explored. When conservatives are considering whether to support humanitarian intervention, they show a bias towards helping Christians over Muslims, but no racial prejudice. Liberals, in contrast, show little to no religious prejudice but are more likely to want to intervene in the scenario where whites are oppressing blacks rather than the other way around. Prejudice can even influence more abstract moral values, as when conservatives heard about Christians being killed by Muslims, they were not only more likely to support humanitarian intervention, but also to say that the United States had a general moral obligation to help foreign populations facing government persecution. The final chapter explores whether psychological differences between conservatives and liberals matter with regards to the making of foreign policy. Relying on measures of affinity, or S-scores, the author uses United Nations General Assembly voting data from six Anglophone democracies to show that in each of these countries conservative governments vote less in line with the rest of the world. This work hopes to inspire future research that can continue to establish a link between political psychology and research on state behavior
