Talk on Tuesday Mar 28, 2023 at 12:30 Place: Zoom Seminar Title: Computational methods to analyse lexical semantic change and variation from historical texts: my experience so far Speaker: Barbara McGillivray, King's College London Abstract: Over time, new words enter the language, others become obsolete, and existing words acquire new meanings. These phenomena are grounded in a fascinatingly complex mix of cognitive, social, and contextual factors, responding to language contact, emerging circumstances, cultural and socio-political changes, stylistic choices, and different communicative needs. The past decade has seen a growing interest in automatic methods for semantic change (i.e. meaning change) detection from large corpus data, which have made it possible to conduct quantitative studies aimed at detecting broad patterns in the data. Most of these automatic detection methods rely on distributional semantics methods and trace th e computational representation of a corpus-driven word&rsquo;s semantic profile (via vector embeddings) over time to identify if and when a potential change in the semantic profile may have occurred. In this talk I will present my research on developing computational models for semantic change detection in historical texts, particularly on ancient Greek and Latin. McGillivray, B. et al. (2019). A computational approach to lexical polysemy in Ancient Greek, Digital Scholarship in the Humanities, 34: 4. McGillivray, B. et al. (2022). A new corpus annotation framework for Latin diachronic lexical semantics. J . Latin Linguistics, vol. 21, No. 1, pp. 47-105.

Outreach Event on Friday Mar 24, 2023 at 15:00 Place: IFISC Seminar Room Title: IFISC X Poster Party Speaker: IFISC PhD students, IFISC (UIB-CSIC) Abstract: The IFISC Poster Party returns in its face-to-face form. An event in which master&#39;s students, doctoral students and postdoctoral researchers will present their research in poster format. In a relaxed atmosphere, you can learn first-hand what young IFISC researchers are working on. This is a great opportunity for undergraduate students to learn what it means to be involved in research, as they will have the chance to speak directly with IFISC researchers themselves. There will be food, drinks, voting and prizes. Url event:https://ifisc.uib-csic.es/en/events/seminars/ifisc-x-poster-party/

Talk on Thursday Mar 16, 2023 at 11:00 Place: Zoom Seminar Title: Quantum trajectories of dissipative time-crystals Speaker: Albert Cabot, Institut für Theoretische Physik, Eberhard Karls Universität Tübingen Abstract: MdM Quantum Meeting Recent experiments with dense laser-driven atomic gases [G. Ferioli et&nbsp; al., arXiv:2207.10361 (2022)] have realized a many-body system which in the thermodynamic limit yields a so-called boundary time-crystal. This state of matter is stabilized by the competition between coherent driving and collective dissipation. The aforementioned experiment in principle allows to gain in situ information on the nonequilibrium dynamics of the system by observing the state of the output light field. We show that the photon count signal as well as the homodyne current allow to identify and characterize critical behavior at the time-crystal phase transition. At the transition point the dynamics of the emission signals feature slow drifts, which are interspersed with sudden strong fluctuations. We furthermore show that the time-integrated homodyne current can serve as a useful dynamical order parameter. From this perspective the time-crystal can be viewed as a state of matter in which different oscillation patterns coexist.

IFISC Seminar on Tuesday Mar 14, 2023 at 14:30 Place: IFISC Seminar Room Title: In-memory Computing – Fundamentals, Current Trends, and Future Directions Speaker: Naresh R. Shanbhag, Department of Electrical & Computing Engineering, University of Illinois Abstract: In-memory computing (IMC) has emerged as an attractive complement to digital accelerators for enhancing the energy efficiency of machine learning tasks. IMC addresses the energy and latency costs of memory accesses dominating AI workloads by transforming the conventional memory accesses into one that computes functions of data in the memory core in an analog/mixed-signal manner. As a result, IMC chips have demonstrated &gt; 100X reduction in the energy-delay product over equivalent von Neumann architectures at iso-accuracy. IMCs also exhibit a fundamental energy vs. SNR trade-off that designers need to exploit to enhance energy efficiency while meeting task-level accuracy requirements. Since the publication of the concept in our ICASSP 2014 paper, IMC design has become an active area of research in the machine learning integrated circuits and architecture communities. This talk will describe IMC design principles, review current trends based on our recent efforts in extensive benchmarking (<a href="https://github.com/naresh-shanbhag/UIUC-IMC-Benchmarking"&g… style="color:#bad405">https://github.com/naresh-shanbhag/UIUC-…) and identify future opportunities and challenges in deploying IMCs at scale in emerging applications.

IFISC Seminar on Wednesday Mar 08, 2023 at 14:30 Place: IFISC Seminar Room Title: Word order theory. Swap distance minimization Speaker: Ramon Ferrer-i-Cancho , UPC Abstract: The syntactic structure of a sentence can be seen as a graph where vertices are words and edges indicate syntactic dependencies between words. Research on these structures has lead to the discovery of many statistical patterns. Some of them have been raised to the category of principles while others have been hypothesized to be manifestations of principles. In this talk, I will review this theoretical framework and delve into the order of four major constituents of a sentence, i.e. Subject, Verb, Object and Indirect Object, in large samples of languages to uncover the action of a recently introduced principle: swap distance minimization. According to that principle, word orders that differ by just one swap of adjacent constituents are easier to process than word orders that differ by the movement of constituents that are farther away. The setting is linguistic but the problem reduces to a space where points are distinct orderings of components and the distance between points is defined by a graph of swaps. I will sketch potential applications to biology.
