Speaker: Michael E. Houle, New Jersey Institute of Technology (NJIT), USAAbstract: Researchers have long considered the analysis of similarity applications in terms of the intrinsic dimensionality (ID) of the data. Although traditionally ID has been viewed as a characterization of the complexity of discrete datasets, more recently a local model of intrinsic dimensionality (LID) has been extended to the case of smooth growth functions in general, and distance distributions in particular, from its first principles in terms of similarity, features, and probability. Since then, LID has found applications — practical as well as theoretical — in such areas as similarity search, data mining, and deep learning. LID has also been shown to be equivalent under transformation to the well-established statistical framework of extreme value theory (EVT). In this tutorial, we will survey some of the wider connections between ID and other forms of complexity analysis, including EVT, power-law distributions, chaos theory, anddynamical systems. We will then see how LID can potentially serve as a unifying framework for the understanding of these theories in the context of machine learning in general, and deep learning in particular.Short Biography: Michael Houle obtained his PhD degree in 1989 from McGill University in Canada, in the area of computational geometry. Since then, he developed research interests in algorithmics, data structures, and relational visualization, first at Kyushu University and the University of Tokyo in Japan, and from 1992 at the University of Newcastle and the University of Sydney in Australia.From 2001 to 2004, while at IBM Japan's Tokyo Research Laboratory, he first began working on approximate similarity search and shared-neighbor clustering methods for data mining applications.From 2004, at the National Institute of Informatics, Tokyo, his research interests expanded to include dimensionality and scalability in the context of fundamental AI / machine learning / data mining tasks such as search, clustering, classification, and outlier detection.In 2021, he relocated to Vancouver, BC, Canada. Currently he is with the New Jersey Institute of Technology in Newark, NJ, USA, and divides his time between Newark and Vancouver.Read more here: https://people.njit.edu/profile/meh43

Speaker: Sarunas Kaubrys (University of Edinburgh) Abstract:In this talk I will start with an overview of Cohomological Donaldson-Thomas (CoDT) theory, which we view as a way to count objects or extract invariants from the moduli space of objects of a 3-Calabi-Yau category. Although the origins of the theory come from the algebraic geometry of coherent sheaves on 3-Calabi-Yau varieties, we will focus on the topological example of closed oriented real 3-manifolds. The category of local systems or fundamental group representations of such a 3-manifold has a canonical 3-Calabi-Yau structure. CoDT invariants for local systems on a 3-manifold can be defined for any connected reductive group and are conjecturally connected to invariants in low dimensional topology called Skein modules. I will present my work on the computation of CoDT invariants of the 3 -torus. The main structural result used in the computation is called cohomological integrality which I will introduce. One of the consequences of such a integrality theorem is a Langlands duality between SLn CoDT invariants and PGLn CoDT invariants for prime n.

Speaker: Ivan G. Costa, Institute for Computational Genomics, RWTH AachenAbstract: Single cell and spatial sequencing allow measuring full transcriptomes or epigenomes of all cells in a tissue. When applied to disease cohorts, several single cell or spatial experiments across distinct patients are available. One open computational problem is how to compare experiments at a sample level, as a sample is represented by a distribution of cells. We will describe in this talk the use of the optimal transport framework as an approach to obtain distances between distributions of cells. This is used for sample level analysis of disease relevant single cell and spatial transcriptomics data to find clusters or trajectories of patients. Another relevant challenge comes from the multi-modal properties of the data, as single cells can be measured in regard to distinct molecular features (transcriptomes and epigenome) or histology data. This requires algorithms for estimation of joint embeddings, which capture information from all available modalities. Finally, we propose statistical methods to interpret results, i.e., to find cell populations and genes related to the detected sample level clusters and trajectories..Short Biography:Ivan G. Costa is Professor for Computational Genomics at the RWTH Aachen. After graduating in computer science in 2003 at the Federal University of Pernambuco (Brazil), he joined the Max Planck Institute for Molecular Genetics (Germany) to pursue doctoral studies in bioinformatics. In 2017, he established a research group on computational genomics at the RWTH Aachen Medical Faculty. His research interest involves statistical machine learning approaches to dissect transcriptional and regulatory programs controlling cellular changes in cell differentiation and in the onset of diseases. He currently focuses on computational methods to understand how cellular microenvironment changes cause or support disease processes by integrative analysis of transcriptional, chromatin and spatial status of single cells.

This event is in DanishNordic Humanities Center og Danish Institute for Advanced Study inviterer til en boglancering og en paneldebat om videnskab og engagement.  I de senere år er forskernes rolle i samfundet blevet genstand for en ny slags opmærksomhed. Dansk forskning befinder sig i dag på en ideologisk kampplads i krydsfeltet mellem woke og anti-woke kampagner, mellem krav om øget samfundsrelevans og anklager om overdreven aktivisme, mellem mediers deklarering af eksperters synspunkter og forskeres understregning af deres videnskabeligt funderede ekspertise. Må forskere have holdninger til deres emne? Findes der noget, vi kan kalde objektiv og værdifri forskning? Hvor langt må politikere gå i styringen af videnskaben?  Med udgangspunkt i den nye bog Videnskab og Engagement: Forskning, politik og medier i det 21. århundrede, redigeret af Anders Engberg-Pedersen, Peter Harder og Martha Sif Karrebæk, inviterer vi til en diskussion af disse helt centrale udfordringer for både videnskaben og samfundet. Paneldeltagere: Stinus Lindgreen, MF, forskningsordfører, Radikale VenstreHanne Leth Andersen, rektor, RUCKaren Vallgårda, professor i historie, KU Med flere.. Debatten varer en time og et kvarter og derefter inviterer Nordic Humanities Center og Danish Institute for Advanced Study på kaffe og kage. Det er gratis at deltage i arrangementet, som foregår i DIAS’ auditoriet på Syddansk Universitet. På dagen vil det være muligt at købe bogen for 100 kr.

12.-13. september samles forskere fra Nordic Humanities Center til et symposium med nordiske kolleger.Titlen på symposiet er ”Individ og stat i den nordiske model – historiske erfaringer og fremtidig samfundsmæssig legitimitet", og det foregår på Linnéuniversitetet i Växsjö i Sverige.

All assistant, associate and full professors at IMADA are invited to the Professor Meeting.Meeting notice and agenda will be sent by email.

In a world of ever-increasing connectivity, talk of ‘globalism’ has become the default setting for academic research: we speak of the global Middle Ages, global modernism, the global South, and so on. And yet at the political level, the world is actually deglobalizing, with the hardening of borders and increasing emphasis on national priorities. National Epics, a project I am currently editing for OUP, takes the opportunity to examine the cultural mechanics of nationalism. Each of over one hundred contributors have been asked: what is the national epic of ‘your’ (assigned) nation? When was the choice made to recognize your key text in this way, how was it curricularized, and how well is this choice holding up today? In France, for example, it was made compulsory by Act of Parliament, in the late 19th century, for the Chanson de Roland to be studied in every French school; how, if at all, is such a text taught today in the multi-faith schools of Paris? ‘Epic’ is of course a weighted, westernized term, but there are equivalent terms elsewhere: the Mahabharata (with the Ramayana) has effectively been the ‘national epic’ of India for two millennia; the Kenyan writer Ngũgĩ wa Thiong'o turned to epic form, with his The Perfect Nine, as recently as 2020. The presentation on 18 September will be relatively brief, hoping to generate broad-ranging discussion and working from the National Epics website. This is publicly accessible: just click on any nation that interests you for a 300-word chapter summary, plus suggestive image.About David WallaceDavid Wallace holds the Judith Rodin Chair of English at the University of Pennsylvania. He is a prominent literary historian who has broken out of the national paradigm in innovative ways. He has published widely on late medieval English literature, and his collaborative project which resulted in the two-volume Europe – A Literary History 1348-1418 (Oxford UP, 2016) is highly acclaimed. He is now editing a global literary history, National Epics, which focuses on national literatures in a large chronological and comparative frame – from Homer to the present day._____________Venue: The DIAS Auditorium (V24-501a-0)OPEN FOR ALL - NO REGISTRATION NEEDED.
