Until now, many theoretical works studied the performance of quantum algorithms for models with a unique ground state. However, when the classical problem is in a so-called clustering phase, the ground state manifold is highly degenerate. As an example, we consider a 3-XORSAT model defined on simple hypergraphs. The degeneracy of classical ground state manifold translates into the emergence of an extensive number of Z2 symmetries, which remain intact even in the presence of a quantum transverse magnetic field. We establish a general duality approach that restricts the quantum problem to a given sector of conserved Z2 charges and use it to study how the outcome of the quantum adiabatic algorithm depends on the hypergraph geometry. We show that the tree hypergraph which corresponds to a classically solvable instance of the 3-XORSAT problem features a constant gap, whereas the closed hypergraph encounters a second-order phase transition with a gap vanishing as a power-law in the problem size. The duality developed in this work provides a practical tool for studies of quantum models with classically degenerate energy manifold and reveals potential connections between glasses and gauge theories."}],"department":[{"_id":"MaSe"}],"title":"Duality approach to quantum annealing of the 3-variable exclusive-or satisfiability problem (3-XORSAT)","publication":"Physical Review A","publisher":"American Physical Society","oa_version":"Preprint","ec_funded":1,"date_created":"2021-12-14T20:46:07Z","day":"14","project":[{"call_identifier":"H2020","_id":"23841C26-32DE-11EA-91FC-C7463DDC885E","grant_number":"850899","name":"Non-Ergodic Quantum Matter: Universality, Dynamics and Control"}],"language":[{"iso":"eng"}],"month":"12","isi":1,"intvolume":"       104","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2106.06344"}],"publication_status":"published","date_published":"2021-12-14T00:00:00Z","author":[{"full_name":"Medina Ramos, Raimel A","id":"CE680B90-D85A-11E9-B684-C920E6697425","first_name":"Raimel A","orcid":"0000-0002-5383-2869","last_name":"Medina Ramos"},{"first_name":"Maksym","last_name":"Serbyn","orcid":"0000-0002-2399-5827","full_name":"Serbyn, Maksym","id":"47809E7E-F248-11E8-B48F-1D18A9856A87"}],"date_updated":"2023-08-17T06:22:49Z","doi":"10.1103/physreva.104.062423","article_processing_charge":"No","quality_controlled":"1","article_number":"062423"},{"publisher":"Springer Nature","title":"Optimal homogenization rates in stochastic homogenization of nonlinear uniformly elliptic equations and systems","department":[{"_id":"JuFi"}],"publication":"Archive for Rational Mechanics and Analysis","oa_version":"Published Version","date_created":"2021-12-16T12:12:33Z","arxiv":1,"abstract":[{"text":"We derive optimal-order homogenization rates for random nonlinear elliptic PDEs with monotone nonlinearity in the uniformly elliptic case.

Such problem arises, for example, as a Lagrangian relaxation of various discrete optimization problems. Our main assumptions are the existence of an efficient linear minimization oracle (lmo) for fP and an efficient proximal map for h∗ which motivate the solution via a blend of proximal primal-dual algorithms and Frank-Wolfe algorithms. In case h∗ is the indicator function of a linear constraint and function f is quadratic, we show a O(1/n2) convergence rate on the dual objective, requiring O(nlogn) calls of lmo. If the problem comes from the constrained optimization problem minx∈Rd{fP(x)|Ax−b=0} then we additionally get bound O(1/n2) both on the primal gap and on the infeasibility gap. In the most general case, we show a O(1/n) convergence rate of the primal-dual gap again requiring O(nlogn) calls of lmo. To the best of our knowledge, this improves on the known convergence rates for the considered class of saddle-point problems.

In this paper, we propose a BFT SMR protocol that achieves the best of both worlds -- optimal linear cost per decision under good networks and leaders, optimal quadratic cost per decision under bad networks, and remains always live.","lang":"eng"}]},{"conference":{"name":"PODC: Principles of Distributed Computing","end_date":"2021-07-30","location":"Virtual, Italy","start_date":"2021-07-26"},"scopus_import":"1","quality_controlled":"1","author":[{"first_name":"Idit","last_name":"Keidar","full_name":"Keidar, Idit"},{"first_name":"Eleftherios","last_name":"Kokoris Kogias","full_name":"Kokoris Kogias, Eleftherios","id":"f5983044-d7ef-11ea-ac6d-fd1430a26d30"},{"full_name":"Naor, Oded","first_name":"Oded","last_name":"Naor"},{"full_name":"Spiegelman, Alexander","first_name":"Alexander","last_name":"Spiegelman"}],"date_published":"2021-07-21T00:00:00Z","date_updated":"2023-08-17T06:24:44Z","doi":"10.1145/3465084.3467905","article_processing_charge":"No","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2102.08325"}],"publication_status":"published","language":[{"iso":"eng"}],"month":"07","isi":1,"day":"21","oa_version":"Preprint","date_created":"2021-12-16T13:21:13Z","title":"All You Need is DAG","department":[{"_id":"ElKo"}],"publication":"Proceedings of the 2021 ACM Symposium on Principles of Distributed Computing","publisher":"Association for Computing Machinery","abstract":[{"text":"We present DAG-Rider, the first asynchronous Byzantine Atomic Broadcast protocol that achieves optimal resilience, optimal amortized communication complexity, and optimal time complexity.

A key challenge towards hybrid Ge-based quantum technologies is the design of high-quality interfaces and superconducting contacts that are robust against magnetic fields. In this work, by combining the assets of aluminum, which provides good contact to the Ge, and niobium, which has a significant superconducting gap, we demonstrate highly transparent low-disordered JoFETs with relatively large ICRN products that are capable of withstanding high magnetic fields. We furthermore demonstrate the ability of phase-biasing individual JoFETs, opening up an avenue to explore topological superconductivity in planar Ge. The persistence of superconductivity in the reported hybrid devices beyond 1.8 T paves the way towards integrating spin qubits and proximity-induced superconductivity on the same chip.","lang":"eng"}],"volume":3,"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","type":"journal_article","_id":"10559","year":"2021","has_accepted_license":"1","status":"public","acknowledgement":"This research and related results were made possible with the support of the NOMIS Foundation.

In contrast to genetic adaptation that spans multiple generations as an evolutionary process, phenotypic plasticity allows acclimation within the life-time of an organism. Genetic adaptation and phenotypic plasticity are usually studied in isolation, however, only by including their interactive impact, we can understand acclimation and adaptation in nature. We aimed to explore the contribution of adaptation and plasticity in coping with an abiotic (salinity) and a biotic (Vibrio bacteria) stressor using six different populations of the broad-nosed pipefish Syngnathus typhle that originated from either high [14–17 Practical Salinity Unit (PSU)] or low (7–11 PSU) saline environments along the German coastline of the Baltic Sea. We exposed wild caught animals, to either high (15 PSU) or low (7 PSU) salinity, representing native and novel salinity conditions and allowed animals to mate. After male pregnancy, offspring was split and each half was exposed to one of the two salinities and infected with Vibrio alginolyticus bacteria that were evolved at either of the two salinities in a fully reciprocal design. We investigated life-history traits of fathers and expression of 47 target genes in mothers and offspring. Pregnant males originating from high salinity exposed to low salinity were highly susceptible to opportunistic fungi infections resulting in decreased offspring size and number. In contrast, no signs of fungal infection were identified in fathers originating from low saline conditions suggesting that genetic adaptation has the potential to overcome the challenges encountered at low salinity. Offspring from parents with low saline origin survived better at low salinity suggesting genetic adaptation to low salinity. In addition, gene expression analyses of juveniles indicated patterns of local adaptation, trans-generational plasticity and developmental plasticity. In conclusion, our study suggests that pipefish are locally adapted to the low salinity in their environment, however, they are retaining phenotypic plasticity, which allows them to also cope with ancestral salinity levels and prevailing pathogens.","lang":"eng"}],"volume":9,"type":"journal_article","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"10568","year":"2021","has_accepted_license":"1","acknowledgement":"We are grateful for the help of Kristina Dauven, Andreas Ebner, Janina Röckner, and Paulina Urban for fish collection in the field and fish maintenance.

The recognition of cues originating from predators can be innate or learned. Cues of various modalities might be used alone or in multi-modal combinations to detect and distinguish predators but studies investigating multi-modal integration in predator avoidance are scarce. Here, we used wild, naive tadpoles of the Neotropical poison frog Allobates femoralis ( Boulenger, 1884) to test their reaction to cues with two modalities from two different sympatrically occurring potential predators: heterospecific predatory Dendrobates tinctorius tadpoles and dragonfly larvae. We presented A. femoralis tadpoles with olfactory or visual cues, or a combination of the two, and compared their reaction to a water control in a between-individual design. In our trials, A. femoralis tadpoles reacted to multi-modal stimuli (a combination of visual and chemical information) originating from dragonfly larvae with avoidance but showed no reaction to uni-modal cues or cues from heterospecific tadpoles. In addition, visual cues from conspecifics increased swimming activity while cues from predators had no effect on tadpole activity. Our results show that A. femoralis tadpoles can innately recognize some predators and probably need both visual and chemical information to effectively avoid them. This is the first study looking at anti-predator behavior in poison frog tadpoles. We discuss how parental care might influence the expression of predator avoidance responses in tadpoles."}],"publisher":"The Company of Biologists","title":"Naïve poison frog tadpoles use bi-modal cues to avoid insect predators but not heterospecific predatory tadpoles","department":[{"_id":"SyCr"}],"publication":"Journal of Experimental Biology","oa_version":"Published Version","date_created":"2021-12-20T07:54:22Z"},{"author":[{"full_name":"Munjal, Akankshi","last_name":"Munjal","first_name":"Akankshi"},{"orcid":"0000-0001-6005-1561","last_name":"Hannezo","first_name":"Edouard B","id":"3A9DB764-F248-11E8-B48F-1D18A9856A87","full_name":"Hannezo, Edouard B"},{"last_name":"Tsai","first_name":"Tony Y.C.","full_name":"Tsai, Tony Y.C."},{"first_name":"Timothy J.","last_name":"Mitchison","full_name":"Mitchison, Timothy J."},{"first_name":"Sean G.","last_name":"Megason","full_name":"Megason, Sean G."}],"date_published":"2021-12-22T00:00:00Z","doi":"10.1016/j.cell.2021.11.025","date_updated":"2023-08-17T06:28:25Z","article_processing_charge":"No","scopus_import":"1","quality_controlled":"1","day":"22","language":[{"iso":"eng"}],"month":"12","isi":1,"intvolume":"       184","main_file_link":[{"open_access":"1","url":"https://www.biorxiv.org/content/10.1101/2020.09.28.316042"}],"publication_status":"published","abstract":[{"lang":"eng","text":"How tissues acquire complex shapes is a fundamental question in biology and regenerative medicine. Zebrafish semicircular canals form from invaginations in the otic epithelium (buds) that extend and fuse to form the hubs of each canal. We find that conventional actomyosin-driven behaviors are not required. Instead, local secretion of hyaluronan, made by the enzymes uridine 5′-diphosphate dehydrogenase (ugdh) and hyaluronan synthase 3 (has3), drives canal morphogenesis. Charged hyaluronate polymers osmotically swell with water and generate isotropic extracellular pressure to deform the overlying epithelium into buds. The mechanical anisotropy needed to shape buds into tubes is conferred by a polarized distribution of actomyosin and E-cadherin-rich membrane tethers, which we term cytocinches. Most work on tissue morphogenesis ascribes actomyosin contractility as the driving force, while the extracellular matrix shapes tissues through differential stiffness. Our work inverts this expectation. Hyaluronate pressure shaped by anisotropic tissue stiffness may be a widespread mechanism for powering morphological change in organogenesis and tissue engineering."}],"title":"Extracellular hyaluronate pressure shaped by cellular tethers drives tissue morphogenesis","department":[{"_id":"EdHa"}],"publication":"Cell","publisher":"Elsevier ; Cell Press","oa_version":"Preprint","date_created":"2021-12-26T23:01:26Z","acknowledgement":"We thank Ian Swinburne, Sandy Nandagopal, and Toru Kawanishi for support, discussions, and reagents.

Recently, Serrano et al. collected the largest dataset to date with subjective ratings of material appearance attributes, including glossiness, metallicness, sharpness and contrast of reflections. In this work, we make use of their dataset to investigate for the first time the impact of the interactions between illumination, geometry, and eight different material categories in perceived appearance attributes. After an initial analysis, we select for further analysis the four material categories that cover the largest range for all perceptual attributes: fabric, plastic, ceramic, and metal. Using a cumulative link mixed model (CLMM) for robust regression, we discover interactions between these material categories and four representative illuminations and object geometries. We believe that our findings contribute to expanding the knowledge on material appearance perception and can be useful for many applications, such as scene design, where any particular material in a given shape can be aligned with dominant classes of illumination, so that a desired strength of appearance attributes can be achieved."}],"type":"journal_article","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","page":"2975-2987","volume":37,"year":"2021","has_accepted_license":"1","_id":"10574","external_id":{"isi":["000673536600003"]},"article_type":"original","issue":"12","acknowledgement":"This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie, grant agreement N∘ 765911 (RealVision) and from the European Research Council (ERC), grant agreement N∘ 804226 (PERDY).

Still the assumption of the no-slip condition is preferred in order to avoid boundary terms in the analysis and slipping effects are usually overlooked. Besides the “static slip models”, there are phenomena that are not accurately described by them, e.g. at the moment when the slip changes rapidly, the wall shear stress and the slip can exhibit a sudden overshoot and subsequent relaxation. When these effects become significant, the so-called dynamic slip phenomenon occurs. We develop a mathematical analysis of Navier–Stokes-like problems with a dynamic slip boundary condition, which requires a proper generalization of the Gelfand triplet and the corresponding function space setting."}],"arxiv":1,"oa_version":"Published Version","date_created":"2021-12-26T23:01:27Z","publisher":"World Scientific Publishing","title":"On the dynamic slip boundary condition for Navier-Stokes-like problems","department":[{"_id":"JuFi"}],"publication":"Mathematical Models and Methods in Applied Sciences","project":[{"_id":"fc31cba2-9c52-11eb-aca3-ff467d239cd2","name":"Taming Complexity in Partial Differential Systems","grant_number":"F6504"},{"name":"Dissipation and Dispersion in Nonlinear Partial Differential Equations","_id":"260788DE-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"}],"language":[{"iso":"eng"}],"isi":1,"month":"10","day":"13","ddc":["510"],"publication_status":"published","file":[{"date_created":"2022-05-16T10:55:45Z","success":1,"content_type":"application/pdf","access_level":"open_access","creator":"dernst","relation":"main_file","checksum":"8c0a9396335f0b70e1f5cbfe450a987a","file_name":"2021_MathModelsMethods_Abbatiello.pdf","file_size":795483,"date_updated":"2022-05-16T10:55:45Z","file_id":"11385"}],"intvolume":"        31","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","quality_controlled":"1","scopus_import":"1","doi":"10.1142/S0218202521500470","date_updated":"2023-08-17T06:29:01Z","article_processing_charge":"No","date_published":"2021-10-13T00:00:00Z","author":[{"first_name":"Anna","last_name":"Abbatiello","full_name":"Abbatiello, Anna"},{"full_name":"Bulíček, Miroslav","first_name":"Miroslav","last_name":"Bulíček"},{"full_name":"Maringová, Erika","id":"dbabca31-66eb-11eb-963a-fb9c22c880b4","first_name":"Erika","last_name":"Maringová"}],"tmp":{"short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"file_date_updated":"2022-05-16T10:55:45Z"},{"department":[{"_id":"GaTk"}],"title":"Token-driven totally asymmetric simple exclusion process","publication":"arXiv","article_number":"2112.13558","oa_version":"Preprint","tmp":{"short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"date_created":"2021-12-28T06:52:09Z","arxiv":1,"date_published":"2021-12-27T00:00:00Z","author":[{"first_name":"Bor","last_name":"Kavcic","orcid":"0000-0001-6041-254X","full_name":"Kavcic, Bor","id":"350F91D2-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Gašper","last_name":"Tkačik","orcid":"0000-0002-6699-1455","full_name":"Tkačik, Gašper","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87"}],"date_updated":"2023-05-03T10:54:05Z","doi":"10.48550/arXiv.2112.13558","article_processing_charge":"No","abstract":[{"text":"We consider a totally asymmetric simple exclusion process (TASEP) consisting of particles on a lattice that require binding by a \"token\" to move.

The demonstrated system consists of a floating solar receiver having a vertically cross-linked microchannel for wicking up saline water. The in situ polymerized Fe2O3@PPy interfacial layer promotes diffuse reflection and its rough black surface allows Omni-directional solar absorption (94%) and facilitates efficient thermal localization at the water/air interface and offers a defect-rich surface to promote heat localization (41.9 °C) and excellent thermal management due to cellulosic content. The self-floating composite foam reveals continuous vapors generation at a rate of 1.52 kg m−2 h−1 under one 1 kW m−2 and profound evaporating efficiency (95%) without heat losses that dissipates in its surroundings. Indeed, long-term evaporation experiments reveal the negligible disparity in continuous evaporation rate (33.84 kg m−2/8.3 h) receiving two sun solar intensity, and ensures the stability of the device under intense seawater conditions synchronized with excellent salt rejection potential. More importantly, Raman spectroscopy investigation validates the orange dye rejection via Fe2O3@PPy solar evaporator. The combined advantages of high efficiency, self-floating capability, multimedia rejection, low cost, and this configuration are promising for producing large-scale solar steam generating systems appropriate for commercial clean water yield due to their scalable fabrication."}],"intvolume":"        11","publication_status":"published","file":[{"access_level":"open_access","creator":"alisjak","relation":"main_file","success":1,"date_created":"2022-01-03T09:46:53Z","content_type":"application/pdf","file_id":"10591","date_updated":"2022-01-03T09:46:53Z","file_name":"2021_Crystals_Yuzheng.pdf","checksum":"668e9d777608ce0a3bc2e305133bd06b","file_size":4569639}],"day":"03","ddc":["620"],"language":[{"iso":"eng"}],"month":"12","isi":1,"file_date_updated":"2022-01-03T09:46:53Z","article_number":"1509","tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_published":"2021-12-03T00:00:00Z","author":[{"full_name":"Lu, Yuzheng","first_name":"Yuzheng","last_name":"Lu"},{"first_name":"Naila","last_name":"Arshad","full_name":"Arshad, Naila"},{"last_name":"Irshad","first_name":"Muhammad Sultan","full_name":"Irshad, Muhammad Sultan"},{"first_name":"Iftikhar","last_name":"Ahmed","full_name":"Ahmed, Iftikhar"},{"full_name":"Ahmad, Shafiq","last_name":"Ahmad","first_name":"Shafiq"},{"last_name":"Alshahrani","first_name":"Lina Abdullah","full_name":"Alshahrani, Lina Abdullah"},{"full_name":"Yousaf, Muhammad","first_name":"Muhammad","last_name":"Yousaf"},{"last_name":"Sayed","first_name":"Abdelaty Edrees","full_name":"Sayed, Abdelaty Edrees"},{"id":"32c21954-2022-11eb-9d5f-af9f93c24e71","full_name":"Nauman, Muhammad","last_name":"Nauman","orcid":"0000-0002-2111-4846","first_name":"Muhammad"}],"date_updated":"2023-08-17T06:31:20Z","alternative_title":["Hybrid and Composite Crystalline Materials"],"doi":"10.3390/cryst11121509","article_processing_charge":"No","scopus_import":"1","quality_controlled":"1"},{"date_created":"2022-01-03T10:50:02Z","oa_version":"Preprint","publication":"35th Conference on Neural Information Processing Systems","title":"PCA initialization for approximate message passing in rotationally invariant models","department":[{"_id":"MaMo"}],"publisher":"Neural Information Processing Systems Foundation","abstract":[{"lang":"eng","text":"We study the problem of estimating a rank-$1$ signal in the presence of rotationally invariant noise-a class of perturbations more general than Gaussian noise. Principal Component Analysis (PCA) provides a natural estimator, and sharp results on its performance have been obtained in the high-dimensional regime. Recently, an Approximate Message Passing (AMP) algorithm has been proposed as an alternative estimator with the potential to improve the accuracy of PCA. However, the existing analysis of AMP requires an initialization that is both correlated with the signal and independent of the noise, which is often unrealistic in practice. In this work, we combine the two methods, and propose to initialize AMP with PCA. Our main result is a rigorous asymptotic characterization of the performance of this estimator. Both the AMP algorithm and its analysis differ from those previously derived in the Gaussian setting: at every iteration, our AMP algorithm requires a specific term to account for PCA initialization, while in the Gaussian case, PCA initialization affects only the first iteration of AMP. The proof is based on a two-phase artificial AMP that first approximates the PCA estimator and then mimics the true AMP. Our numerical simulations show an excellent agreement between AMP results and theoretical predictions, and suggest an interesting open direction on achieving Bayes-optimal performance."}],"arxiv":1,"_id":"10593","year":"2021","volume":35,"page":"29616-29629","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"conference","citation":{"apa":"Mondelli, M., &#38; Venkataramanan, R.

From a theoretical perspective, two possible explanations have been proposed: (i) the loss function has connected sublevel sets, and (ii) the solutions found by stochastic gradient descent are dropout stable. While these explanations provide insights into the phenomenon, their assumptions are not always satisfied in practice. In particular, the first approach requires the network to have one layer with order of N neurons (N being the number of training samples), while the second one requires the loss to be almost invariant after removing half of the neurons at each layer (up to some rescaling of the remaining ones). In this work, we improve both conditions by exploiting the quality of the features at every intermediate layer together with a milder over-parameterization condition. More specifically, we show that: (i) under generic assumptions on the features of intermediate layers, it suffices that the last two hidden layers have order of N−−√ neurons, and (ii) if subsets of features at each layer are linearly separable, then no over-parameterization is needed to show the connectivity. Our experiments confirm that the proposed condition ensures the connectivity of solutions found by stochastic gradient descent, even in settings where the previous requirements do not hold.","lang":"eng"}],"arxiv":1,"year":"2021","_id":"10594","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"conference","volume":35,"publication_identifier":{"issn":["1049-5258"],"isbn":["9781713845393"]},"citation":{"apa":"Nguyen, Q., Bréchet, P., &#38; Mondelli, M.

In particular, the smallest eigenvalue of the NTK has been related to the memorization capacity, the global convergence of gradient descent algorithms and the generalization of deep nets. However, existing results either provide bounds in the two-layer setting or assume that the spectrum of the NTK matrices is bounded away from 0 for multi-layer networks. In this paper, we provide tight bounds on the smallest eigenvalue of NTK matrices for deep ReLU nets, both in the limiting case of infinite widths and for finite widths. In the finite-width setting, the network architectures we consider are fairly general: we require the existence of a wide layer with roughly order of $N$ neurons, $N$ being the number of data samples; and the scaling of the remaining layer widths is arbitrary (up to logarithmic factors). To obtain our results, we analyze various quantities of independent interest: we give lower bounds on the smallest singular value of hidden feature matrices, and upper bounds on the Lipschitz constant of input-output feature maps."}],"arxiv":1,"oa_version":"Published Version","date_created":"2022-01-03T10:57:49Z","department":[{"_id":"MaMo"}],"title":"Tight bounds on the smallest eigenvalue of the neural tangent kernel for deep ReLU networks","publication":"Proceedings of the 38th International Conference on Machine Learning","publisher":"ML Research Press"},{"language":[{"iso":"eng"}],"project":[{"_id":"059876FA-7A3F-11EA-A408-12923DDC885E","name":"Prix Lopez-Loretta 2019 - Marco Mondelli"}],"isi":1,"month":"09","day":"01","publication_status":"published","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2011.12882"}],"quality_controlled":"1","scopus_import":"1","date_updated":"2024-09-10T13:03:18Z","doi":"10.1109/isit45174.2021.9517887","article_processing_charge":"No","date_published":"2021-09-01T00:00:00Z","author":[{"full_name":"Fathollahi, Dorsa","last_name":"Fathollahi","first_name":"Dorsa"},{"full_name":"Farsad, Nariman","first_name":"Nariman","last_name":"Farsad"},{"full_name":"Hashemi, Seyyed Ali","first_name":"Seyyed Ali","last_name":"Hashemi"},{"full_name":"Mondelli, Marco","id":"27EB676C-8706-11E9-9510-7717E6697425","first_name":"Marco","orcid":"0000-0002-3242-7020","last_name":"Mondelli"}],"conference":{"location":"Virtual, Melbourne, Australia","start_date":"2021-07-12","name":"ISIT: International Symposium on Information Theory","end_date":"2021-07-20"},"publication_identifier":{"eisbn":["978-1-5386-8209-8"],"isbn":["978-1-5386-8210-4"]},"citation":{"ama":"Fathollahi D, Farsad N, Hashemi SA, Mondelli M.
