However, for a reliable and verifiable quantum simulation, the building blocks of the quantum device require exquisite benchmarking. This benchmarking of large-scale dynamical quantum systems represents a major challenge due to lack of efficient tools for their simulation.

We illustrate our approach using a model for a forefront quantum simulation platform: ultracold atoms in optical lattices.

However, data concerning embryologists’ ability to predict implantation probability using TLI is still lacking. Emerging technologies based on data-driven tools have shown great promise for improving embryo selection and predicting clinical outcomes.\r\n\r\nSTUDY DESIGN, SIZE, DURATION: TLI video files of 136 embryos with known implantation data were retrospectively collected from two clinical sites between 2018 and 2019 for the performance assessment of 36 embryologists and comparison with a deep neural network (DNN).\r\n\r\nPARTICIPANTS/MATERIALS, SETTING, METHODS: We recruited 39 embryologists from 13 different countries. All participants were blinded to clinical outcomes. A total of 136 TLI videos of embryos that reached the blastocyst stage were used for this experiment. Each embryo’s likelihood of successfully implanting was assessed by 36 embryologists, providing implantation probability grades (IPGs) from 1 to 5, where 1 indicates a very low likelihood of implantation and 5 indicates a very high likelihood. Subsequently, three embryologists with over 5 years of experience provided Gardner scores. All 136 blastocysts were categorized into three quality groups based on their Gardner scores. Embryologist predictions were then converted into predictions of implantation (IPG ≥ 3) and no implantation (IPG ≤ 2). Embryologists’ performance and agreement were assessed using Fleiss kappa coefficient. A 10-fold cross-validation DNN was developed to provide IPGs for TLI video files. The model’s performance was compared to that of the embryologists.\r\n\r\nMAIN RESULTS AND THE ROLE OF CHANCE: Logistic regression was employed for the following confounding variables: country of residence, academic level, embryo scoring system, log years of experience and experience using TLI. None were found to have a statistically significant impact on embryologist performance at α = 0.05. The average implantation prediction accuracy for the embryologists was 51.9% for all embryos (N = 136). The average accuracy of the embryologists when assessing top quality and poor quality embryos (according to the Gardner score categorizations) was 57.5% and 57.4%, respectively, and 44.6% for fair quality embryos. Overall interobserver agreement was moderate (κ = 0.56, N = 136). The best agreement was achieved in the poor + top quality group (κ = 0.65, N = 77), while the agreement in the fair quality group was lower (κ = 0.25, N = 59). The DNN showed an overall accuracy rate of 62.5%, with accuracies of 62.2%, 61% and 65.6% for the poor, fair and top quality groups, respectively. The AUC for the DNN was higher than that of the embryologists overall (0.70 DNN vs 0.61 embryologists) as well as in all of the Gardner groups (DNN vs embryologists—Poor: 0.69 vs 0.62; Fair: 0.67 vs 0.53; Top: 0.77 vs 0.54).\r\n\r\nLIMITATIONS, REASONS FOR CAUTION: Blastocyst assessment was performed using video files acquired from time-lapse incubators, where each video contained data from a single focal plane. Clinical data regarding the underlying cause of infertility and endometrial thickness before the transfer was not available, yet may explain implantation failure and lower accuracy of IPGs. Implantation was defined as the presence of a gestational sac, whereas the detection of fetal heartbeat is a more robust marker of embryo viability. The raw data were anonymized to the extent that it was not possible to quantify the number of unique patients and cycles included in the study, potentially masking the effect of bias from a limited patient pool. Furthermore, the lack of demographic data makes it difficult to draw conclusions on how representative the dataset was of the wider population. Finally, embryologists were required to assess the implantation potential, not embryo quality. Although this is not the traditional approach to embryo evaluation, morphology/morphokinetics as a means of assessing embryo quality is believed to be strongly correlated with viability and, for some methods, implantation potential.\r\n\r\nWIDER IMPLICATIONS OF THE FINDINGS: Embryo selection is a key element in IVF success and continues to be a challenge. Improving the predictive ability could assist in optimizing implantation success rates and other clinical outcomes and could minimize the financial and emotional burden on the patient. This study demonstrates moderate agreement rates between embryologists, likely due to the subjective nature of embryo assessment. In particular, we found that average embryologist accuracy and agreement were significantly lower for fair quality embryos when compared with that for top and poor quality embryos. Using data-driven algorithms as an assistive tool may help IVF professionals increase success rates and promote much needed standardization in the IVF clinic. Our results indicate a need for further research regarding technological advancement in this field."}]},{"publication_identifier":{"issn":["0167-8655"]},"type":"journal_article","publication":"Pattern Recognition Letters","quality_controlled":"1","publisher":"Elsevier","OA_place":"repository","fulldoi":"https://doi.org/10.1016/j.patrec.2022.06.012","publication_status":"published","scopus_import":"1","title":"Baby steps towards few-shot learning with multiple semantics","page":"142-147","intvolume":"       160","date_created":"2024-10-08T12:54:03Z","external_id":{"arxiv":["1906.01905"]},"date_updated":"2024-10-14T10:58:20Z","main_file_link":[{"url":"https://arxiv.org/abs/1906.01905","open_access":"1"}],"oa":1,"oa_version":"Preprint","day":"01","_id":"18224","language":[{"iso":"eng"}],"extern":"1","year":"2022","author":[{"full_name":"Schwartz, Eli","first_name":"Eli","last_name":"Schwartz"},{"first_name":"Leonid","full_name":"Karlinsky, Leonid","last_name":"Karlinsky"},{"full_name":"Feris, Rogerio","first_name":"Rogerio","last_name":"Feris"},{"full_name":"Giryes, Raja","first_name":"Raja","last_name":"Giryes"},{"id":"58f3726e-7cba-11ef-ad8b-e6e8cb3904e6","last_name":"Bronstein","full_name":"Bronstein, Alexander","first_name":"Alexander","orcid":"0000-0001-9699-8730"}],"month":"08","date_published":"2022-08-01T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_type":"original","doi":"10.1016/j.patrec.2022.06.012","citation":{"ieee":"E.

While considerable progress has been achieved in few-shot learning from a few image examples, much less attention has been given to the verbal descriptions that are usually provided to infants when they are presented with a new object. In this paper, we focus on the role of additional semantics that can significantly facilitate few-shot visual learning. Building upon recent advances in few-shot learning with additional semantic information, we demonstrate that further improvements are possible by combining multiple and richer semantics (category labels, attributes, and natural language descriptions). Using these ideas, we offer the community new results on the popular miniImageNet and CUB few-shot benchmarks, comparing favorably to the previous state-of-the-art results for both visual only and visual plus semantics-based approaches. We also performed an ablation study investigating the components and design choices of our approach.

In order to enable an efficient and more applicable isometric feature mapping, a diverse set of sophisticated advancements have been proposed to the original algorithm to incorporate important factors like sparsity of computation, conformality, topological constraints and spectral geometry. However, a significant shortcoming of most approaches is the dependence on large-scale dense-spectral decompositions and the inability to generalize to points far away from the sampling of the manifold.\r\nIn this paper, we explore an unsupervised deep learning approach for computing distance-preserving maps for non-linear dimensionality reduction. We demonstrate that our framework is general enough to incorporate all previous advancements and show a significantly improved local and non-local generalization of the isometric mapping.

One of the main open challenges is how to directly generate a desirable qudit state in the SPDC process. This problem can be addressed through advanced computational learning methods; however, due to difficulties in modeling the SPDC process by a fully differentiable algorithm, progress has been limited. Here, we overcome these limitations and introduce a physically constrained and differentiable model, validated against experimental results for shaped pump beams and structured crystals, capable of learning the relevant interaction parameters in the process. We avoid any restrictions induced by the stochastic nature of our physical model and integrate the dynamic equations governing the evolution under the SPDC Hamiltonian. We solve the inverse problem of designing a nonlinear quantum optical system that achieves the desired quantum state of downconverted photon pairs. The desired states are defined using either the second-order correlations between different spatial modes or by specifying the required density matrix. By learning nonlinear photonic crystal structures as well as different pump shapes, we successfully show how to generate maximally entangled states. Furthermore, we simulate all-optical coherent control over the generated quantum state by actively changing the profile of the pump beam. Our work can be useful for applications such as novel designs of high-dimensional quantum key distribution and quantum information processing protocols. In addition, our method can be readily applied for controlling other degrees of freedom of light in the SPDC process, such as spectral and temporal properties, and may even be used in condensed-matter systems having a similar interaction Hamiltonian.","lang":"eng"}],"article_processing_charge":"No","volume":9,"quality_controlled":"1","publication":"Optica","type":"journal_article","publication_identifier":{"issn":["2334-2536"]},"scopus_import":"1","fulldoi":"https://doi.org/10.1364/optica.451115","publication_status":"published","OA_place":"publisher","publisher":"Optica Publishing Group","title":"Inverse design of spontaneous parametric downconversion for generation of high-dimensional qudits","page":"602-615","date_updated":"2024-10-14T11:07:29Z","date_created":"2024-10-08T12:54:43Z","intvolume":"         9","day":"06","oa":1,"oa_version":"Published Version","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1364/OPTICA.451115"}]},{"page":"116-132","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2103.10994","open_access":"1"}],"oa_version":"None","oa":1,"day":"23","date_created":"2024-10-08T12:55:44Z","intvolume":"     13691","external_id":{"arxiv":["2103.10994"]},"date_updated":"2024-10-15T07:04:39Z","publication_identifier":{"eissn":["1611-3349"],"issn":["0302-9743"],"eisbn":["9783031198212"],"isbn":["9783031198205"]},"type":"conference","publication":"17th European Conference on Computer Vision","quality_controlled":"1","title":"Self-supervised classification network","publisher":"Springer Nature","fulldoi":"https://doi.org/10.1007/978-3-031-19821-2_7","publication_status":"published","scopus_import":"1","doi":"10.1007/978-3-031-19821-2_7","citation":{"mla":"Amrani, Elad, et al. “Self-Supervised Classification Network.” <i>17th European Conference on Computer Vision</i>, vol. 13691, Springer Nature, 2022, pp. 116–32, doi:<a href=\"https://doi.org/10.1007/978-3-031-19821-2_7\">10.1007/978-3-031-19821-2_7</a>.","apa":"Amrani, E., Karlinsky, L., &#38; Bronstein, A.

In our theoretical analysis, we prove that degenerate solutions are not in the set of optimal solutions of our approach. Self-Classifier is simple to implement and scalable. Unlike other popular unsupervised classification and contrastive representation learning approaches, it does not require any form of pre-training, expectation-maximization, pseudo-labeling, external clustering, a second network, stop-gradient operation, or negative pairs.

However, to achieve an economic impact, the polycrystalline counterpart needs to replicate the performance of the single crystal. Herein, we optimize the thermoelectric performance of polycrystalline SnSe produced by consolidating solution-processed and surface-engineered SnSe particles. In particular, the SnSe particles are coated with CdSe molecular complexes that crystallize during the sintering process, forming CdSe nanoparticles. The presence of CdSe nanoparticles inhibits SnSe grain growth during the consolidation step due to Zener pinning, yielding a material with a high density of grain boundaries. Moreover, the resulting SnSe–CdSe nanocomposites present a large number of defects at different length scales, which significantly reduce the thermal conductivity. The produced SnSe–CdSe nanocomposites exhibit thermoelectric figures of merit up to 2.2 at 786 K, which is among the highest reported for solution-processed SnSe.","lang":"eng"}],"acknowledgement":"This work was financially supported by IST Austria and the Werner Siemens Foundation.

The level of cortical tension outside of the cell–cell contact, when pulling at the contact edge, scales with the total size to which a cell–cell contact can grow [J.-L. Maître et al., Science 338, 253–256 (2012)]. Here, we show in zebrafish primary germ-layer progenitor cells that this monotonic relationship only applies to a narrow range of cortical tension increase and that above a critical threshold, contact size inversely scales with cortical tension. This switch from cortical tension increasing to decreasing progenitor cell–cell contact size is caused by cortical tension promoting E-cadherin anchoring to the actomyosin cytoskeleton, thereby increasing clustering and stability of E-cadherin at the contact. After tension-mediated E-cadherin stabilization at the contact exceeds a critical threshold level, the rate by which the contact expands in response to pulling forces from the cortex sharply drops, leading to smaller contacts at physiologically relevant timescales of contact formation. Thus, the activity of cortical tension in expanding cell–cell contact size is limited by tension-stabilizing E-cadherin–actin complexes at the contact."}],"acknowledgement":"We thank Guillaume Salbreaux, Silvia Grigolon, Edouard Hannezo, and Vanessa Barone for discussions and comments on the manuscript and Shayan Shamipour and Daniel Capek for help with data analysis.

Many Enterobacteriaceae express type 1 pili, a pre-adapted virulence trait, to invade host epithelial cells and establish persistent infections. However, the molecular mechanisms and strategies by which bacteria actively circumvent the immune response of the host remain poorly understood. Here, we identified CD14, the major co-receptor for lipopolysaccharide detection, on mouse dendritic cells (DCs) as a binding partner of FimH, the protein located at the tip of the type 1 pilus of Escherichia coli. The FimH amino acids involved in CD14 binding are highly conserved across pathogenic and non-pathogenic strains. Binding of the pathogenic strain CFT073 to CD14 reduced DC migration by overactivation of integrins and blunted expression of co-stimulatory molecules by overactivating the NFAT (nuclear factor of activated T-cells) pathway, both rate-limiting factors of T cell activation. This response was binary at the single-cell level, but averaged in larger populations exposed to both piliated and non-piliated pathogens, presumably via the exchange of immunomodulatory cytokines. While defining an active molecular mechanism of immune evasion by pathogens, the interaction between FimH and CD14 represents a potential target to interfere with persistent and recurrent infections, such as urinary tract infections or Crohn’s disease.","lang":"eng"}],"acknowledgement":"We thank Ulrich Dobrindt for providing UPEC strains CFT073, UTI89, and 536, Frank Assen, Vlad Gavra, Maximilian Götz, Bor Kavčič, Jonna Alanko, and Eva Kiermaier for help with experiments and Robert Hauschild, Julian Stopp, and Saren Tasciyan for help with data analysis.

Yet, the dynamic organization of its underlying neuronal population activity remains elusive. Here we uncover a unique organizational principle regulating collective neural dynamics associated with the alpha rhythm in the awake resting-state. We demonstrate that cascades of neural activity obey attenuation-amplification dynamics (AAD), with a transition from the attenuation regime—within alpha cycles—to the amplification regime—across a few alpha cycles—that correlates with the characteristic frequency of the alpha rhythm. We find that this short-term AAD is part of a large-scale, size-dependent temporal structure of neural cascades that obeys the Omori law: Following large cascades, smaller cascades occur at a rate that decays as a power-law of the time elapsed from such events—a long-term AAD regulating brain activity over the timescale of seconds. We show that such an organization corresponds to the \"waxing and waning\" of the alpha rhythm. Importantly, we observe that short- and long-term AAD are unique to the awake resting-state, being absent during NREM sleep. These results provide a quantitative, dynamical description of the so-far-qualitative notion of the \"waxing and waning\" phenomenon, and suggest the AAD as a key principle governing resting-state dynamics across timescales.","lang":"eng"}],"acknowledgement":"FL acknowledges support from the European Union’s Horizon 2020 research and innovation program under the Marie Sklodowska-Curie Grant Agreement No. 754411.

While the matched Bayes-optimal setting with unstructured noise is well understood, the analysis of this mismatched problem is only at its premises. In this paper, we make a step towards understanding the effect of the strong source of mismatch which is the noise statistics. Our main technical contribution is the rigorous analysis of a Bayes estimator and of an approximate message passing (AMP) algorithm, both of which incorrectly assume a Gaussian setup. The first result exploits the theory of spherical integrals and of low-rank matrix perturbations; the idea behind the second one is to design and analyze an artificial AMP which, by taking advantage of the flexibility in the denoisers, is able to \"correct\" the mismatch. Armed with these sharp asymptotic characterizations, we unveil a rich and often unexpected phenomenology. For example, despite AMP is in principle designed to efficiently compute the Bayes estimator, the former is outperformed by the latter in terms of mean-square error. We show that this performance gap is due to an incorrect estimation of the signal norm. In fact, when the SNR is large enough, the overlaps of the AMP and the Bayes estimator coincide, and they even match those of optimal estimators taking into account the structure of the noise."}],"status":"public","year":"2022","language":[{"iso":"eng"}],"_id":"12536","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"11","date_published":"2022-11-20T00:00:00Z","author":[{"last_name":"Barbier","full_name":"Barbier, Jean","first_name":"Jean"},{"last_name":"Hou","full_name":"Hou, TianQi","first_name":"TianQi"},{"id":"27EB676C-8706-11E9-9510-7717E6697425","last_name":"Mondelli","first_name":"Marco","orcid":"0000-0002-3242-7020","full_name":"Mondelli, Marco"},{"first_name":"Manuel","full_name":"Saenz, Manuel","last_name":"Saenz"}],"alternative_title":["Advances in Neural Information Processing Systems"],"conference":{"end_date":"2022-12-09","start_date":"2022-11-28","name":"NeurIPS: Neural Information Processing Systems","location":"New Orleans, LA, United States"},"das_tickbox":"1","oa_version":"Preprint","oa":1,"day":"20","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2205.10009"}],"date_updated":"2026-07-07T06:38:45Z","date_created":"2023-02-10T13:45:41Z","intvolume":"        35","external_id":{"arxiv":["2205.10009"]},"type":"conference","publication":"36th Conference on Neural Information Processing Systems","quality_controlled":"1","publication_identifier":{"isbn":["9781713871088"],"issn":["1049-5258"]},"title":"The price of ignorance: How much does it cost to forget noise structure in low-rank matrix estimation?","scopus_import":"1","department":[{"_id":"MaMo"}],"publisher":"Neural Information Processing Systems Foundation","publication_status":"published"},{"conference":{"name":"CONCUR: Conference on Concurrency Theory","location":"Warsaw, Poland","end_date":"2022-09-16","start_date":"2022-09-13"},"author":[{"full_name":"Grover, Kush","first_name":"Kush","last_name":"Grover"},{"id":"44CEF464-F248-11E8-B48F-1D18A9856A87","last_name":"Kretinsky","full_name":"Kretinsky, Jan","first_name":"Jan","orcid":"0000-0002-8122-2881"},{"orcid":"0000-0002-1712-2165","first_name":"Tobias","full_name":"Meggendorfer, Tobias","last_name":"Meggendorfer","id":"b21b0c15-30a2-11eb-80dc-f13ca25802e1"},{"full_name":"Weininger, Maimilian","first_name":"Maimilian","last_name":"Weininger"}],"alternative_title":["LIPIcs"],"month":"09","date_published":"2022-09-15T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"12775","language":[{"iso":"eng"}],"year":"2022","status":"public","abstract":[{"text":"We consider the problem of approximating the reachability probabilities in Markov decision processes (MDP) with uncountable (continuous) state and action spaces. While there are algorithms that, for special classes of such MDP, provide a sequence of approximations converging to the true value in the limit, our aim is to obtain an algorithm with guarantees on the precision of the approximation.\r\nAs this problem is undecidable in general, assumptions on the MDP are necessary. Our main contribution is to identify sufficient assumptions that are as weak as possible, thus approaching the \"boundary\" of which systems can be correctly and reliably analyzed. To this end, we also argue why each of our assumptions is necessary for algorithms based on processing finitely many observations.\r\nWe present two solution variants. The first one provides converging lower bounds under weaker assumptions than typical ones from previous works concerned with guarantees. The second one then utilizes stronger assumptions to additionally provide converging upper bounds. Altogether, we obtain an anytime algorithm, i.e. yielding a sequence of approximants with known and iteratively improving precision, converging to the true value in the limit. Besides, due to the generality of our assumptions, our algorithms are very general templates, readily allowing for various heuristics from literature in contrast to, e.g., a specific discretization algorithm. Our theoretical contribution thus paves the way for future practical improvements without sacrificing correctness guarantees.","lang":"eng"}],"volume":243,"article_processing_charge":"No","corr_author":"1","arxiv":1,"acknowledgement":"Kush Grover: The author has been supported by the DFG research training group GRK\r\n2428 ConVeY.\r\nMaximilian Weininger: The author has been partially supported by DFG projects 383882557\r\nStatistical Unbounded Verification (SUV) and 427755713 Group-By Objectives in Probabilistic\r\nVerification (GOPro)","file":[{"access_level":"open_access","checksum":"e282e43d3ae0ba6e067b72f4583e13c0","content_type":"application/pdf","relation":"main_file","file_name":"2022_LIPIcS_Grover.pdf","success":1,"date_created":"2023-09-26T10:43:15Z","date_updated":"2023-09-26T10:43:15Z","file_size":960036,"creator":"dernst","file_id":"14372"}],"ddc":["000"],"citation":{"short":"K.
