Extensive research has elucidated the signaling mechanisms governing ERK activation via biochemical regulations with upstream molecules, particularly receptor tyrosine kinases (RTKs). However, recent advances have highlighted the role of mechanical forces in activating the RTK–ERK signaling pathways, thereby opening new avenues of research into mechanochemical interplay in multicellular tissues. Here, we review the force-induced ERK activation in cells and propose possible mechanosensing mechanisms underlying the mechanoresponsive ERK activation. We conclude that mechanical forces are not merely passive factors shaping cells and tissues but also active regulators of cellular signaling pathways controlling collective cell behaviors.","lang":"eng"}],"day":"01","doi":"10.1016/j.ceb.2023.102217","ddc":["570"],"acknowledgement":"TH was supported by JSPS KAKENHI Grant (no. 21H05290) and the Ministry of Education under the Research Centres of Excellence programme through the Mechanobiology Institute at National University of Singapore and by Department of Physiology at National University of Singapore.

Although these methods measure changes in global barrier function, they lack the sensitivity needed to detect local or transient barrier breaches, and they do not reveal the location of barrier leaks. Therefore, we previously developed a method that we named the zinc-based ultrasensitive microscopic barrier assay (ZnUMBA), which overcomes these limitations, allowing for detection of local tight junction leaks with high spatiotemporal resolution. Here, we present expanded applications for ZnUMBA. ZnUMBA can be used in Xenopus embryos to measure the dynamics of barrier restoration and actin accumulation following laser injury. ZnUMBA can also be effectively utilized in developing zebrafish embryos as well as cultured monolayers of Madin–Darby canine kidney (MDCK) II epithelial cells. ZnUMBA is a powerful and flexible method that, with minimal optimization, can be applied to multiple systems to measure dynamic changes in barrier function with spatiotemporal precision."}],"quality_controlled":"1","ec_funded":1,"file_date_updated":"2023-08-21T07:37:54Z","publisher":"The Company of Biologists","article_type":"original","scopus_import":"1","_id":"14082","issue":"15","author":[{"last_name":"Higashi","first_name":"Tomohito","full_name":"Higashi, Tomohito"},{"full_name":"Stephenson, Rachel E.","last_name":"Stephenson","first_name":"Rachel E."},{"id":"3436488C-F248-11E8-B48F-1D18A9856A87","last_name":"Schwayer","first_name":"Cornelia","full_name":"Schwayer, Cornelia","orcid":"0000-0001-5130-2226"},{"id":"44C6F6A6-F248-11E8-B48F-1D18A9856A87","full_name":"Huljev, Karla","first_name":"Karla","last_name":"Huljev"},{"full_name":"Higashi, Atsuko Y.","first_name":"Atsuko Y.","last_name":"Higashi"},{"id":"39427864-F248-11E8-B48F-1D18A9856A87","last_name":"Heisenberg","first_name":"Carl-Philipp J","full_name":"Heisenberg, Carl-Philipp J","orcid":"0000-0002-0912-4566"},{"full_name":"Chiba, Hideki","first_name":"Hideki","last_name":"Chiba"},{"first_name":"Ann L.","last_name":"Miller","full_name":"Miller, Ann L."}],"department":[{"_id":"CaHe"},{"_id":"EvBe"}],"date_created":"2023-08-20T22:01:13Z","article_processing_charge":"No","publication_status":"published","intvolume":"       136","title":"ZnUMBA - a live imaging method to detect local barrier breaches"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","file":[{"file_name":"2023_LIPIcsICALP_Resch.pdf","content_type":"application/pdf","date_updated":"2023-08-21T07:23:18Z","file_size":1141497,"checksum":"a449143fec3fbebb092cb8ef3b53c226","date_created":"2023-08-21T07:23:18Z","creator":"dernst","file_id":"14091","access_level":"open_access","relation":"main_file","success":1}],"type":"conference","date_published":"2023-07-01T00:00:00Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"oa":1,"publication_identifier":{"isbn":["9783959772785"],"issn":["1868-8969"]},"language":[{"iso":"eng"}],"conference":{"start_date":"2023-07-10","name":"ICALP: International Colloquium on Automata, Languages, and Programming","location":"Paderborn, Germany","end_date":"2023-07-14"},"has_accepted_license":"1","publication":"50th International Colloquium on Automata, Languages, and Programming","article_number":"99","month":"07","oa_version":"Published Version","ddc":["000"],"volume":261,"acknowledgement":"Nicolas Resch: Research supported in part by ERC H2020 grant No.74079 (ALGSTRONGCRYPTO).

A code is called (p,L)_q-list-decodable if every radius pn Hamming ball contains less than L codewords; (p,𝓁,L)_q-list-recoverability is a generalization where we place radius pn Hamming balls on every point of a combinatorial rectangle with side length 𝓁 and again stipulate that there be less than L codewords.\r\nOur main contribution is to precisely calculate the maximum value of p for which there exist infinite families of positive rate (p,𝓁,L)_q-list-recoverable codes, the quantity we call the zero-rate threshold. Denoting this value by p_*, we in fact show that codes correcting a p_*+ε fraction of errors must have size O_ε(1), i.e., independent of n. Such a result is typically referred to as a \"Plotkin bound.\" To complement this, a standard random code with expurgation construction shows that there exist positive rate codes correcting a p_*-ε fraction of errors. We also follow a classical proof template (typically attributed to Elias and Bassalygo) to derive from the zero-rate threshold other tradeoffs between rate and decoding radius for list-decoding and list-recovery.\r\nTechnically, proving the Plotkin bound boils down to demonstrating the Schur convexity of a certain function defined on the q-simplex as well as the convexity of a univariate function derived from it. We remark that an earlier argument claimed similar results for q-ary list-decoding; however, we point out that this earlier proof is flawed."}],"day":"01","doi":"10.4230/LIPIcs.ICALP.2023.99","arxiv":1,"file_date_updated":"2023-08-21T07:23:18Z","quality_controlled":"1","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","author":[{"full_name":"Resch, Nicolas","first_name":"Nicolas","last_name":"Resch"},{"full_name":"Yuan, Chen","first_name":"Chen","last_name":"Yuan"},{"orcid":"0000-0002-6465-6258","full_name":"Zhang, Yihan","first_name":"Yihan","last_name":"Zhang","id":"2ce5da42-b2ea-11eb-bba5-9f264e9d002c"}],"scopus_import":"1","_id":"14083","intvolume":"       261","title":"Zero-rate thresholds and new capacity bounds for list-decoding and list-recovery","alternative_title":["LIPIcs"],"department":[{"_id":"MaMo"}],"date_created":"2023-08-20T22:01:13Z","article_processing_charge":"Yes","publication_status":"published"},{"publication":"50th International Colloquium on Automata, Languages, and Programming","has_accepted_license":"1","oa_version":"Published Version","month":"07","article_number":"72","language":[{"iso":"eng"}],"conference":{"location":"Paderborn, Germany","end_date":"2023-07-14","start_date":"2023-07-10","name":"ICALP: International Colloquium on Automata, Languages, and Programming"},"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"date_published":"2023-07-01T00:00:00Z","type":"conference","publication_identifier":{"issn":["1868-8969"],"isbn":["9783959772785"]},"oa":1,"file":[{"content_type":"application/pdf","file_name":"2023_LIPIcsICALP_Harris.pdf","date_updated":"2023-08-21T06:45:16Z","checksum":"6dee0684245bb1c524b9c955db1e933d","file_size":917791,"date_created":"2023-08-21T06:45:16Z","creator":"dernst","file_id":"14088","access_level":"open_access","success":1,"relation":"main_file"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","_id":"14084","scopus_import":"1","author":[{"last_name":"Harris","first_name":"David G.","full_name":"Harris, David G."},{"id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87","full_name":"Kolmogorov, Vladimir","last_name":"Kolmogorov","first_name":"Vladimir"}],"publication_status":"published","department":[{"_id":"VlKo"}],"date_created":"2023-08-20T22:01:14Z","article_processing_charge":"Yes","title":"Parameter estimation for Gibbs distributions","alternative_title":["LIPIcs"],"intvolume":"       261","quality_controlled":"1","file_date_updated":"2023-08-21T06:45:16Z","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","date_updated":"2023-08-21T06:49:11Z","citation":{"mla":"Harris, David G., and Vladimir Kolmogorov. “Parameter Estimation for Gibbs Distributions.” <i>50th International Colloquium on Automata, Languages, and Programming</i>, vol. 261, 72, Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2023, doi:<a href=\"https://doi.org/10.4230/LIPIcs.ICALP.2023.72\">10.4230/LIPIcs.ICALP.2023.72</a>.","short":"D.G.

Though tight approximation algorithms for general matroid constraints exist in theory, the running times of such algorithms typically scale quadratically, and are not practical for truly large scale settings. Recent progress has focused on fast algorithms for important classes of matroids given in explicit form. Currently, nearly-linear time algorithms only exist for graphic and partition matroids [Alina Ene and Huy L. Nguyen, 2019]. In this work, we develop algorithms for monotone submodular maximization constrained by graphic, transversal matroids, or laminar matroids in time near-linear in the size of their representation. Our algorithms achieve an optimal approximation of 1-1/e-ε and both generalize and accelerate the results of Ene and Nguyen [Alina Ene and Huy L. Nguyen, 2019]. In fact, the running time of our algorithm cannot be improved within the fast continuous greedy framework of Badanidiyuru and Vondrák [Ashwinkumar Badanidiyuru and Jan Vondrák, 2014].\r\nTo achieve near-linear running time, we make use of dynamic data structures that maintain bases with approximate maximum cardinality and weight under certain element updates. These data structures need to support a weight decrease operation and a novel Freeze operation that allows the algorithm to freeze elements (i.e. force to be contained) in its basis regardless of future data structure operations. For the laminar matroid, we present a new dynamic data structure using the top tree interface of Alstrup, Holm, de Lichtenberg, and Thorup [Stephen Alstrup et al., 2005] that maintains the maximum weight basis under insertions and deletions of elements in O(log n) time. This data structure needs to support certain subtree query and path update operations that are performed every insertion and deletion that are non-trivial to handle in conjunction. For the transversal matroid the Freeze operation corresponds to requiring the data structure to keep a certain set S of vertices matched, a property that we call S-stability. While there is a large body of work on dynamic matching algorithms, none are S-stable and maintain an approximate maximum weight matching under vertex updates. We give the first such algorithm for bipartite graphs with total running time linear (up to log factors) in the number of edges.","lang":"eng"}],"citation":{"chicago":"Henzinger, Monika H, Paul Liu, Jan Vondrák, and Da Wei Zheng. “Faster Submodular Maximization for Several Classes of Matroids.” In <i>50th International Colloquium on Automata, Languages, and Programming</i>, Vol. 261.

We study theoretically the incompressible flow profiles around ±1 defects induced by polar and dipolar active forces. We show that dipolar forces induce vortical flows around the +1 defect, while the flow around the −1 defect has an 8-fold rotational symmetry. The vortical flow changes its chirality near the +1 defect core in the absence of the friction with a substrate. We show analytically that the flow induced by polar active forces is vortical near the +1 defect and is 4-fold symmetric near the −1 defect, while it becomes uniform in the far-field. For a pair of oppositely charged defects, this polar flow contributes to a mutual interaction force that depends only on the orientation of the defect pair relative to the background polarization, and that enhances defect pair annihilation. This is in contradiction with the effect of dipolar active forces which decay inversely proportional with the defect separation distance. As such, our analyses reveals a long-ranged mechanism for the pairwise interaction between topological defects in polar active matter."}],"date_updated":"2024-01-30T12:49:24Z","year":"2023","citation":{"ista":"Rønning J, Renaud JB, Doostmohammadi A, Angheluta L. 2023.

Many transient phenomena will remain enigmatic until we achieve a firm understanding of the physics and evolution of massive stars at low metallicity (Z). The Hubble Space Telescope has devoted 500 orbits to observing ∼250 massive stars at low Z in the ultraviolet (UV) with the COS and STIS spectrographs under the ULLYSES programme. The complementary X-Shooting ULLYSES (XShootU) project provides an enhanced legacy value with high-quality optical and near-infrared spectra obtained with the wide-wavelength coverage X-shooter spectrograph at ESO’s Very Large Telescope. We present an overview of the XShootU project, showing that combining ULLYSES UV and XShootU optical spectra is critical for the uniform determination of stellar parameters such as effective temperature, surface gravity, luminosity, and abundances, as well as wind properties such as mass-loss rates as a function of Z. As uncertainties in stellar and wind parameters percolate into many adjacent areas of astrophysics, the data and modelling of the XShootU project is expected to be a game changer for our physical understanding of massive stars at low Z. To be able to confidently interpret James Webb Space Telescope spectra of the first stellar generations, the individual spectra of low-Z stars need to be understood, which is exactly where XShootU can deliver.","lang":"eng"}],"quality_controlled":"1","publisher":"EDP Sciences","article_type":"original","_id":"14103","scopus_import":"1","author":[{"first_name":"Jorick S.","last_name":"Vink","full_name":"Vink, Jorick S."},{"full_name":"Mehner, A.","last_name":"Mehner","first_name":"A."},{"full_name":"Crowther, P.

In this work, we have computed the first grid of evolutionary models of TŻOs with the MESA stellar evolution code. With these models, we predict several observational properties of TŻOs, including their surface temperatures and luminosities, pulsation periods, and nucleosynthetic products. We expand the range of possible TŻO solutions to cover 3.45≲log(Teff/K)≲3.65 and 4.85≲log(L/L⊙)≲5.5⁠. Due to the much higher densities our TŻOs reach compared to previous models, if TŻOs form we expect them to be stable over a larger mass range than previously predicted, without exhibiting a gap in their mass distribution. Using the GYRE stellar pulsation code we show that TŻOs should have fundamental pulsation periods of 1000–2000 d, and period ratios of ≈0.2–0.3. Models computed with a large 399 isotope fully coupled nuclear network show a nucleosynthetic signal that is different to previously predicted. We propose a new nucleosynthetic signal to determine a star’s status as a TŻO: the isotopologues 44TiO2 and 44TiO⁠, which will have a shift in their spectral features as compared to stable titanium-containing molecules. We find that in the local Universe (∼SMC metallicities and above) TŻOs show little heavy metal enrichment, potentially explaining the difficulty in finding TŻOs to-date.","lang":"eng"}],"date_updated":"2023-08-21T12:12:48Z","year":"2023","citation":{"ieee":"R.

Many recently proposed approaches try to counter this by aligning the model to the new distribution prior to inference. With no labels available this requires unsupervised objectives to adapt the model on the observed test data. In this paper, we propose Test-Time SelfTraining (TeST): a technique that takes as input a model trained on some source data and a novel data distribution at test time, and learns invariant and robust representations using a student-teacher framework. We find that models adapted using TeST significantly improve over baseline testtime adaptation algorithms. TeST achieves competitive performance to modern domain adaptation algorithms [4, 43], while having access to 5-10x less data at time of adaption. We thoroughly evaluate a variety of baselines on two tasks:\r\nobject detection and image segmentation and find that models adapted with TeST. We find that TeST sets the new stateof-the art for test-time domain adaptation algorithms.

Most machine learning efforts addressing this issue in an unsupervised setting have focused on slot-based methods, which may be limiting due to their discrete nature and difficulty to express uncertainty. Recently, the Complex AutoEncoder was proposed as an alternative that learns continuous and distributed object-centric representations. However, it is only applicable to simple toy data. In this paper, we present Rotating Features, a generalization of complex-valued features to higher dimensions, and a new evaluation procedure for extracting objects from distributed representations. Additionally, we show the applicability of our approach to pre-trained features. Together, these advancements enable us to scale distributed object-centric representations from simple toy to real-world data. We believe this work advances a new paradigm for addressing the binding problem in machine learning and has the potential to inspire further innovation in the field.","lang":"eng"}],"oa":1,"language":[{"iso":"eng"}],"publication":"arXiv","_id":"14207","author":[{"full_name":"Löwe, Sindy","first_name":"Sindy","last_name":"Löwe"},{"full_name":"Lippe, Phillip","first_name":"Phillip","last_name":"Lippe"},{"id":"26cfd52f-2483-11ee-8040-88983bcc06d4","orcid":"0000-0002-4850-0683","full_name":"Locatello, Francesco","first_name":"Francesco","last_name":"Locatello"},{"last_name":"Welling","first_name":"Max","full_name":"Welling, Max"}],"oa_version":"Preprint","publication_status":"submitted","department":[{"_id":"FrLo"}],"article_processing_charge":"No","date_created":"2023-08-22T14:18:00Z","month":"06","title":"Rotating features for object discovery","article_number":"2306.00600"},{"external_id":{"arxiv":["2305.19377"]},"date_updated":"2023-09-13T08:46:46Z","year":"2023","citation":{"short":"Z.

For this purpose, we unify three interrelated concepts of overparameterization, benign overfitting, and the Lipschitz constant of DNNs. Our results indicate that interpolating with smoother functions leads to better generalization. Furthermore, we investigate the special case where interpolating smooth ground-truth functions is performed by DNNs under the Neural Tangent Kernel (NTK) regime for generalization. Our result demonstrates that the generalization error converges to a constant order that only depends on label noise and initialization noise, which theoretically verifies benign overfitting.

It is an open question whether the generalization capabilities of diffusion models beyond using the additional data of the pre-training process for augmentation lead to improved downstream performance. We perform a systematic evaluation of existing methods to generate images from diffusion models and study new extensions to assess their benefit for data augmentation. While we find that personalizing diffusion models towards the target data outperforms simpler prompting strategies, we also show that using the training data of the diffusion model alone, via a simple nearest neighbor retrieval procedure, leads to even stronger downstream performance.

Assuming each supervised task only depends on an unknown subset of the factors of variation, we disentangle the feature space of a supervised multi-task model, with features activating sparsely across different tasks and information being shared as appropriate. Importantly, we never directly observe the factors of variations but establish that access to multiple tasks is sufficient for identifiability under sufficiency and minimality assumptions.

Leveraging scalable machine learning approaches to approximate the score function ∇logp(X), we extend the work of Rolland et al. (2022) that only recovers the topological order from the score and requires an expensive pruning step removing spurious edges among those admitted by the ordering. Our analysis leads to DAS (acronym for Discovery At Scale), a practical algorithm that reduces the complexity of the pruning by a factor proportional to the graph size. In practice, DAS achieves competitive accuracy with current state-of-the-art while being over an order of magnitude faster. Overall, our approach enables principled and scalable causal discovery, significantly lowering the compute bar."}],"oa":1,"arxiv":1,"day":"01","extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","main_file_link":[{"url":"https://arxiv.org/abs/2304.03382","open_access":"1"}]},{"_id":"14214","publication":"2nd Conference on Causal Learning and Reasoning","author":[{"last_name":"Liu","first_name":"Yuejiang","full_name":"Liu, Yuejiang"},{"full_name":"Alahi, Alexandre","first_name":"Alexandre","last_name":"Alahi"},{"full_name":"Russell, Chris","first_name":"Chris","last_name":"Russell"},{"full_name":"Horn, Max","last_name":"Horn","first_name":"Max"},{"full_name":"Zietlow, Dominik","last_name":"Zietlow","first_name":"Dominik"},{"last_name":"Schölkopf","first_name":"Bernhard","full_name":"Schölkopf, Bernhard"},{"id":"26cfd52f-2483-11ee-8040-88983bcc06d4","last_name":"Locatello","first_name":"Francesco","full_name":"Locatello, Francesco","orcid":"0000-0002-4850-0683"}],"oa_version":"Preprint","publication_status":"published","department":[{"_id":"FrLo"}],"date_created":"2023-08-22T14:20:18Z","article_processing_charge":"No","title":"Causal triplet: An open challenge for intervention-centric causal representation learning","month":"04","quality_controlled":"1","language":[{"iso":"eng"}],"conference":{"name":"CLeaR: Conference on Causal Learning and Reasoning","start_date":"2023-04-11","location":"Tübingen, Germany","end_date":"2023-04-14"},"date_updated":"2023-09-13T09:23:08Z","citation":{"apa":"Liu, Y., Alahi, A., Russell, C., Horn, M., Zietlow, D., Schölkopf, B., &#38; Locatello, F.

Yet, existing efforts are largely limited to simple synthetic settings that are far away from real-world problems. In this paper, we present Causal Triplet, a causal representation learning benchmark featuring not only visually more complex scenes, but also two crucial desiderata commonly overlooked in previous works: (i) an actionable counterfactual setting, where only certain object-level variables allow for counterfactual observations whereas others do not; (ii) an interventional downstream task with an emphasis on out-of-distribution robustness from the independent causal mechanisms principle. Through extensive experiments, we find that models built with the knowledge of disentangled or object-centric representations significantly outperform their distributed counterparts. However, recent causal representation learning methods still struggle to identify such latent structures, indicating substantial challenges and opportunities for future work.","lang":"eng"}],"oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2301.05169"}],"extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public"},{"conference":{"location":"Kigali, Rwanda","end_date":"2023-05-05","start_date":"2023-05-01","name":"International Conference on Machine Learning Representations"},"language":[{"iso":"eng"}],"quality_controlled":"1","title":"Relative representations enable zero-shot latent space communication","month":"05","date_created":"2023-08-22T14:22:20Z","department":[{"_id":"FrLo"}],"article_processing_charge":"No","oa_version":"Preprint","publication_status":"published","author":[{"last_name":"Moschella","first_name":"Luca","full_name":"Moschella, Luca"},{"last_name":"Maiorca","first_name":"Valentino","full_name":"Maiorca, Valentino"},{"full_name":"Fumero, Marco","first_name":"Marco","last_name":"Fumero"},{"first_name":"Antonio","last_name":"Norelli","full_name":"Norelli, Antonio"},{"id":"26cfd52f-2483-11ee-8040-88983bcc06d4","full_name":"Locatello, Francesco","orcid":"0000-0002-4850-0683","last_name":"Locatello","first_name":"Francesco"},{"full_name":"Rodolà, Emanuele","first_name":"Emanuele","last_name":"Rodolà"}],"_id":"14217","publication":"The 11th International Conference on Learning Representations","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","extern":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2209.15430"}],"oa":1,"abstract":[{"text":"Neural networks embed the geometric structure of a data manifold lying in a high-dimensional space into latent representations. Ideally, the distribution of the data points in the latent space should depend only on the task, the data, the loss, and other architecture-specific constraints. However, factors such as the random weights initialization, training hyperparameters, or other sources of randomness in the training phase may induce incoherent latent spaces that hinder any form of reuse. Nevertheless, we empirically observe that, under the same data and modeling choices, the angles between the encodings within distinct latent spaces do not change. In this work, we propose the latent similarity between each sample and a fixed set of anchors as an alternative data representation, demonstrating that it can enforce the desired invariances without any additional training. We show how neural architectures can leverage these relative representations to guarantee, in practice, invariance to latent isometries and rescalings, effectively enabling latent space communication: from zero-shot model stitching to latent space comparison between diverse settings. We extensively validate the generalization capability of our approach on different datasets, spanning various modalities (images, text, graphs), tasks (e.g., classification, reconstruction) and architectures (e.g., CNNs, GCNs, transformers).","lang":"eng"}],"day":"01","arxiv":1,"type":"conference","external_id":{"arxiv":["2209.15430"]},"date_published":"2023-05-01T00:00:00Z","citation":{"chicago":"Moschella, Luca, Valentino Maiorca, Marco Fumero, Antonio Norelli, Francesco Locatello, and Emanuele Rodolà. “Relative Representations Enable Zero-Shot Latent Space Communication.” In <i>The 11th International Conference on Learning Representations</i>, 2023.","ieee":"L.

Allowing machine learning algorithms to derive this decomposition in an unsupervised way has become an important line of research. However, current methods are restricted to simulated data or require additional information in the form of motion or depth in order to successfully discover objects. In this work, we overcome this limitation by showing that reconstructing features from models trained in a self-supervised manner is a sufficient training signal for object-centric representations to arise in a fully unsupervised way. Our approach, DINOSAUR, significantly out-performs existing image-based object-centric learning models on simulated data and is the first unsupervised object-centric model that scales to real-world datasets such as COCO and PASCAL VOC. DINOSAUR is conceptually simple and shows competitive performance compared to more involved pipelines from the computer vision literature.","lang":"eng"}],"oa":1,"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2209.14860"}],"extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public"}]
