The main scaling approach is data-parallel GPU-based training, which has been boosted by hardware and software support for highly efficient point-to-point communication, and in particular via hardware bandwidth over-provisioning. Overprovisioning comes at a cost: there is an order of magnitude price difference between \"cloud-grade\" servers with such support, relative to their popular \"consumer-grade\" counterparts, although single server-grade and consumer-grade GPUs can have similar computational envelopes.\r\n\r\nIn this paper, we show that the costly hardware overprovisioning approach can be supplanted via algorithmic and system design, and propose a framework called CGX, which provides efficient software support for compressed communication in ML applications, for both multi-GPU single-node training, as well as larger-scale multi-node training. CGX is based on two technical advances: At the system level, it relies on a re-developed communication stack for ML frameworks, which provides flexible, highly-efficient support for compressed communication. At the application level, it provides seamless, parameter-free integration with popular frameworks, so that end-users do not have to modify training recipes, nor significant training code. This is complemented by a layer-wise adaptive compression technique which dynamically balances compression gains with accuracy preservation. CGX integrates with popular ML frameworks, providing up to 3X speedups for multi-GPU nodes based on commodity hardware, and order-of-magnitude improvements in the multi-node setting, with negligible impact on accuracy.","lang":"eng"}],"publication_identifier":{"isbn":["9781450393409"]},"month":"11","year":"2022","department":[{"_id":"DaAl"}],"publisher":"Association for Computing Machinery","oa_version":"Published Version","ddc":["000"],"type":"conference","file":[{"relation":"main_file","file_id":"12795","creator":"dernst","file_name":"2022_ACMMiddleware_Markov.pdf","date_created":"2023-04-03T06:17:58Z","success":1,"checksum":"1a397746235f245da5468819247ff663","file_size":1514169,"date_updated":"2023-04-03T06:17:58Z","access_level":"open_access","content_type":"application/pdf"}],"_id":"12780","publication_status":"published","external_id":{"arxiv":["2111.08617"]},"doi":"10.1145/3528535.3565248","file_date_updated":"2023-04-03T06:17:58Z","article_processing_charge":"Yes (via OA deal)","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"publication":"Proceedings of the 23rd ACM/IFIP International Middleware Conference","acknowledgement":"The authors sincerely thank Nikoli Dryden, Tal Ben-Nun, Torsten Hoefler and Bapi Chatterjee for useful discussions throughout the development of this project.","day":"01","has_accepted_license":"1","date_published":"2022-11-01T00:00:00Z","page":"241-254","title":"CGX: Adaptive system support for communication-efficient deep learning","oa":1,"date_created":"2023-03-31T06:17:00Z","citation":{"ama":"Markov I, Ramezanikebrya H, Alistarh D-A.

We introduce Relational Memorization (RM) to understand, quantify and control this phenomenon. While bounding general memorization can have detrimental effects on the performance of a trained model, bounding RM does not prevent effective learning. The difference is most pronounced when the data distribution is long-tailed, with many queries having only few training examples: Impeding general memorization prevents effective learning, while impeding only relational memorization still allows learning general properties of the underlying concepts. We formalize the notion of Relational Privacy (RP) and, inspired by Differential Privacy (DP), we provide a possible definition of Differential Relational Privacy (DrP). These notions can be used to describe and compute bounds on the amount of RM in a trained model. We illustrate Relational Privacy concepts in experiments with large-scale models for Question Answering.","lang":"eng"}],"doi":"10.48550/arXiv.2203.16701","status":"public","article_processing_charge":"No","author":[{"full_name":"Bombari, Simone","last_name":"Bombari","id":"ca726dda-de17-11ea-bc14-f9da834f63aa","first_name":"Simone"},{"full_name":"Achille, Alessandro","last_name":"Achille","first_name":"Alessandro"},{"full_name":"Wang, Zijian","last_name":"Wang","first_name":"Zijian"},{"full_name":"Wang, Yu-Xiang","last_name":"Wang","first_name":"Yu-Xiang"},{"full_name":"Xie, Yusheng","last_name":"Xie","first_name":"Yusheng"},{"first_name":"Kunwar Yashraj","last_name":"Singh","full_name":"Singh, Kunwar Yashraj"},{"last_name":"Appalaraju","full_name":"Appalaraju, Srikar","first_name":"Srikar"},{"full_name":"Mahadevan, Vijay","last_name":"Mahadevan","first_name":"Vijay"},{"first_name":"Stefano","full_name":"Soatto, Stefano","last_name":"Soatto"}],"oa":1,"article_number":"2203.16701","publication_status":"submitted","arxiv":1,"external_id":{"arxiv":["2203.16701"]},"_id":"12860","oa_version":"Preprint","type":"preprint","date_created":"2023-04-23T16:11:48Z","citation":{"chicago":"Bombari, Simone, Alessandro Achille, Zijian Wang, Yu-Xiang Wang, Yusheng Xie, Kunwar Yashraj Singh, Srikar Appalaraju, Vijay Mahadevan, and Stefano Soatto. “Towards Differential Relational Privacy and Its Use in Question Answering.” <i>ArXiv</i>, n.d. <a href=\"https://doi.org/10.48550/arXiv.2203.16701\">https://doi.org/10.48550/arXiv.2203.16701</a>.","apa":"Bombari, S., Achille, A., Wang, Z., Wang, Y.-X., Xie, Y., Singh, K.

Immunological challenge causes LNs to increase more than tenfold in size within a few days. Here, we characterized the biomechanics of LN swelling on the cellular and organ scale. We identified lymphocyte trapping by influx and proliferation as drivers of an outward pressure force, causing fibroblastic reticular cells of the T-zone (TRCs) and their associated conduits to stretch. After an initial phase of relaxation, TRCs sensed the resulting strain through cell matrix adhesions, which coordinated local growth and remodeling of the stromal network. While the expanded TRC network readopted its typical configuration, a massive fibrotic reaction of the organ capsule set in and countered further organ expansion.

Here, we explored the development of the neurotransmitter identity of neurons of the avian nucleus isthmi parvocellularis (Ipc), whose axon terminals are retinotopically arranged in the optic tectum (TeO) and exert a focal gating effect upon the ascending transmission of retinal inputs. Although cholinergic and glutamatergic markers are both found in Ipc neurons and terminals of adult pigeons and chicks, the mRNA expression of the vesicular acetylcholine transporter, VAChT, is weak or absent. To explore how the Ipc neurotransmitter identity is established during ontogeny, we analyzed the expression of mRNAs coding for cholinergic (ChAT, VAChT, and CHT) and glutamatergic (VGluT2 and VGluT3) markers in chick embryos at different developmental stages. We found that between E12 and E18, Ipc neurons expressed all cholinergic mRNAs and also VGluT2 mRNA; however, from E16 through posthatch stages, VAChT mRNA expression was specifically diminished. Our ex vivo deposits of tracer crystals and intracellular filling experiments revealed that Ipc axons exhibit a mature paintbrush morphology late in development, experiencing marked morphological transformations during the period of presumptive dual vesicular transmitter release. Additionally, although ChAT protein immunoassays increasingly label the growing Ipc axon, this labeling was consistently restricted to sparse portions of the terminal branches. Combined, these results suggest that the synthesis of glutamate and acetylcholine, and their vesicular release, is complexly linked to the developmental processes of branching, growing and remodeling of these unique axons.","lang":"eng"}],"scopus_import":"1","date_updated":"2023-08-11T10:58:17Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"department":[{"_id":"MaJö"}],"article_type":"original","publication_identifier":{"eissn":["1096-9861"],"issn":["0021-9967"]},"isi":1,"month":"02","year":"2022","type":"journal_article","oa_version":"None","external_id":{"pmid":["34363623"],"isi":["000686420000001"]},"publication_status":"published","issue":"2","_id":"9955","publisher":"Wiley"},{"status":"public","author":[{"first_name":"William","id":"41B03CD0-62AE-11E9-84EF-0718E6697425","full_name":"Mistegaard, William","last_name":"Mistegaard"},{"full_name":"Andersen, Jørgen Ellegaard","last_name":"Andersen","first_name":"Jørgen Ellegaard"}],"language":[{"iso":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_updated":"2023-08-02T06:53:51Z","scopus_import":"1","abstract":[{"lang":"eng","text":"For a Seifert fibered homology sphere X we show that the q-series invariant Zˆ0(X; q) introduced by Gukov-Pei-Putrov-Vafa, is a resummation of the Ohtsuki series Z0(X).

However, most methods are designed for verification of an idealized model of the actual network which works over real arithmetic and ignores rounding imprecisions. This idealization is in stark contrast to network quantization, which is a technique that trades numerical precision for computational efficiency and is, therefore, often applied in practice. Neglecting rounding errors of such low-bit quantized neural networks has been shown to lead to wrong conclusions about the network’s correctness. Thus, the desired approach for verifying quantized neural networks would be one that takes these rounding errors\r\ninto account. In this paper, we show that verifying the bitexact implementation of quantized neural networks with bitvector specifications is PSPACE-hard, even though verifying idealized real-valued networks and satisfiability of bit-vector specifications alone are each in NP. Furthermore, we explore several practical heuristics toward closing the complexity gap between idealized and bit-exact verification. In particular, we propose three techniques for making SMT-based verification of quantized neural networks more scalable. Our experiments demonstrate that our proposed methods allow a speedup of up to three orders of magnitude over existing approaches."}],"scopus_import":"1","date_updated":"2025-07-14T09:10:11Z","language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Scalable verification of quantized neural networks","page":"3787-3795","date_created":"2022-01-25T15:15:02Z","citation":{"mla":"Henzinger, Thomas A., et al. “Scalable Verification of Quantized Neural Networks.” <i>Proceedings of the AAAI Conference on Artificial Intelligence</i>, vol. 35, no. 5A, AAAI Press, 2021, pp. 3787–95.","apa":"Henzinger, T.

While adversarial training appears to enhance the robustness and safety of a deep model deployed in open-world decision-critical applications, counterintuitively, it induces undesired behaviors in robot learning settings. In this paper, we show theoretically and experimentally that neural controllers obtained via adversarial training are subjected to three types of defects, namely transient, systematic, and conditional errors. We first generalize adversarial training to a safety-domain optimization scheme allowing for more generic specifications. We then prove that such a learning process tends to cause certain error profiles. We support our theoretical results by a thorough experimental safety analysis in a robot-learning task. Our results suggest that adversarial training is not yet ready for robot learning."}],"publication_identifier":{"eisbn":["978-1-7281-9077-8"],"eissn":["2577-087X"],"issn":["1050-4729"],"isbn":["978-1-7281-9078-5"]},"isi":1,"project":[{"grant_number":"Z211","_id":"25F42A32-B435-11E9-9278-68D0E5697425","name":"The Wittgenstein Prize","call_identifier":"FWF"}],"year":"2021","department":[{"_id":"GradSch"},{"_id":"ToHe"}],"ddc":["000"],"oa_version":"None","type":"conference","external_id":{"arxiv":["2103.08187"],"isi":["000765738803040"]},"publication_status":"published","_id":"10666"},{"oa_version":"Published Version","type":"conference","file":[{"relation":"main_file","creator":"mlechner","file_id":"10682","file_name":"infinite_time_horizon_safety_o.pdf","date_created":"2022-01-26T07:39:59Z","file_size":452492,"success":1,"checksum":"0fc0f852525c10dda9cc9ffea07fb4e4","date_updated":"2022-01-26T07:39:59Z","content_type":"application/pdf","access_level":"open_access"}],"ddc":["000"],"alternative_title":[" Advances in Neural Information Processing Systems"],"external_id":{"arxiv":["2111.03165"]},"publication_status":"published","_id":"10667","department":[{"_id":"GradSch"},{"_id":"ToHe"},{"_id":"KrCh"}],"project":[{"call_identifier":"H2020","name":"International IST Doctoral Program","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","grant_number":"665385"},{"grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","name":"Formal Methods for Stochastic Models: Algorithms and Applications","call_identifier":"H2020"},{"_id":"25F42A32-B435-11E9-9278-68D0E5697425","name":"The Wittgenstein Prize","call_identifier":"FWF","grant_number":"Z211"}],"year":"2021","month":"12","related_material":{"record":[{"id":"11362","relation":"dissertation_contains","status":"public"}]},"main_file_link":[{"url":"https://proceedings.neurips.cc/paper/2021/hash/544defa9fddff50c53b71c43e0da72be-Abstract.html","open_access":"1"}],"abstract":[{"lang":"eng","text":"Bayesian neural networks (BNNs) place distributions over the weights of a neural network to model uncertainty in the data and the network's prediction. We consider the problem of verifying safety when running a Bayesian neural network policy in a feedback loop with infinite time horizon systems. Compared to the existing sampling-based approaches, which are inapplicable to the infinite time horizon setting, we train a separate deterministic neural network that serves as an infinite time horizon safety certificate. In particular, we show that the certificate network guarantees the safety of the system over a subset of the BNN weight posterior's support. Our method first computes a safe weight set and then alters the BNN's weight posterior to reject samples outside this set. Moreover, we show how to extend our approach to a safe-exploration reinforcement learning setting, in order to avoid unsafe trajectories during the training of the policy. We evaluate our approach on a series of reinforcement learning benchmarks, including non-Lyapunovian safety specifications."}],"date_updated":"2025-07-14T09:10:12Z","user_id":"2EBD1598-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"status":"public","author":[{"full_name":"Lechner, Mathias","last_name":"Lechner","id":"3DC22916-F248-11E8-B48F-1D18A9856A87","first_name":"Mathias"},{"last_name":"Žikelić","full_name":"Žikelić, Ðorđe","first_name":"Ðorđe"},{"orcid":"0000-0002-4561-241X","last_name":"Chatterjee","full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu"},{"id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A","full_name":"Henzinger, Thomas A","last_name":"Henzinger","orcid":"0000-0002-2985-7724"}],"citation":{"ama":"Lechner M, Žikelić Ð, Chatterjee K, Henzinger TA.

To this end, our paper extends the receptive field of convolutional neural networks with two residual components, ubiquitous in the visual processing system of vertebrates: On-center and off-center pathways, with an excitatory center and inhibitory surround; OOCS for short. The On-center pathway is excited by the presence of a light stimulus in its center, but not in its surround, whereas the Off-center pathway is excited by the absence of a light stimulus in its center, but not in its surround. We design OOCS pathways via a difference of Gaussians, with their variance computed analytically from the size of the receptive fields. OOCS pathways complement each other in their response to light stimuli, ensuring this way a strong edge-detection capability, and as a result an accurate and robust inference under challenging lighting conditions. We provide extensive empirical evidence showing that networks supplied with OOCS pathways gain accuracy and illumination-robustness from the novel edge representation, compared to other baselines."}],"main_file_link":[{"open_access":"1","url":"https://proceedings.mlr.press/v139/babaiee21a"}],"publication_identifier":{"issn":["2640-3498"]},"year":"2021","month":"07","project":[{"call_identifier":"FWF","name":"The Wittgenstein Prize","_id":"25F42A32-B435-11E9-9278-68D0E5697425","grant_number":"Z211"}],"department":[{"_id":"GradSch"},{"_id":"ToHe"}],"publisher":"ML Research Press","type":"conference","file":[{"access_level":"open_access","content_type":"application/pdf","date_updated":"2022-01-26T07:38:32Z","success":1,"checksum":"d30eae62561bb517d9f978437d7677db","file_size":4246561,"date_created":"2022-01-26T07:38:32Z","file_name":"babaiee21a.pdf","file_id":"10681","creator":"mlechner","relation":"main_file"}],"oa_version":"Published Version","ddc":["000"],"_id":"10668","alternative_title":["PMLR"],"publication_status":"published","file_date_updated":"2022-01-26T07:38:32Z","article_processing_charge":"No","tmp":{"image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/3.0/legalcode","short":"CC BY-NC-ND (3.0)"},"volume":139,"publication":"Proceedings of the 38th International Conference on Machine Learning","day":"01","acknowledgement":"Z.B. is supported by the Doctoral College Resilient Embedded Systems, which is run jointly by the TU Wien’s Faculty of Informatics and the UAS Technikum Wien.

SLR inherently avoids the infamous wrapping effect (accumulation of over-approximation errors) by performing local optimization steps to expand safe regions instead of repeatedly forward-propagating them as is done by deterministic reachability methods. To enable fast local optimizations, we introduce a novel forward-mode adjoint sensitivity method to compute gradients without the need for backpropagation. Finally, we establish asymptotic and non-asymptotic convergence rates for SLR."}],"date_updated":"2022-05-24T06:33:14Z","language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"file_date_updated":"2022-01-26T07:37:24Z","article_processing_charge":"No","tmp":{"image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/3.0/legalcode","short":"CC BY-NC-ND (3.0)"},"acknowledgement":"C.V., R.H.

However, such techniques often rely on traditional discrete-time neural models and face difficulties in generalizing to domain shifts by failing to account for the causal relationships between the agent and the environment. In this paper, we propose a theoretical and experimental framework for learning causal representations using continuous-time neural networks, specifically over their discrete-time counterparts. We evaluate our method in the context of visual-control learning of drones over a series of complex tasks, ranging from short- and long-term navigation, to chasing static and dynamic objects through photorealistic environments. Our results demonstrate that causal continuous-time\r\ndeep models can perform robust navigation tasks, where advanced recurrent models fail. These models learn complex causal control representations directly from raw visual inputs and scale to solve a variety of tasks using imitation learning."}],"main_file_link":[{"url":"https://proceedings.neurips.cc/paper/2021/hash/67ba02d73c54f0b83c05507b7fb7267f-Abstract.html","open_access":"1"}],"year":"2021","month":"12","project":[{"grant_number":"Z211","call_identifier":"FWF","name":"The Wittgenstein Prize","_id":"25F42A32-B435-11E9-9278-68D0E5697425"}],"department":[{"_id":"GradSch"},{"_id":"ToHe"}],"file":[{"creator":"mlechner","file_id":"10679","relation":"main_file","file_name":"NeurIPS-2021-causal-navigation-by-continuous-time-neural-networks-Paper.pdf","file_size":6841228,"checksum":"be81f0ade174a8c9b2d4fe09590b2021","success":1,"date_created":"2022-01-26T07:37:24Z","content_type":"application/pdf","access_level":"open_access","date_updated":"2022-01-26T07:37:24Z"}],"type":"conference","ddc":["000"],"oa_version":"Published Version","_id":"10670","external_id":{"arxiv":["2106.08314"]},"alternative_title":[" Advances in Neural Information Processing Systems"],"publication_status":"published"},{"title":"Liquid time-constant networks","page":"7657-7666","conference":{"location":"Virtual","end_date":"2021-02-09","name":"AAAI: Association for the Advancement of Artificial Intelligence","start_date":"2021-02-02"},"quality_controlled":"1","arxiv":1,"date_created":"2022-01-25T15:48:36Z","citation":{"ama":"Hasani R, Lechner M, Amini A, Rus D, Grosu R.

Instead of declaring a learning system’s dynamics by implicit nonlinearities, we construct networks of linear first-order dynamical systems modulated via nonlinear interlinked gates. The resulting models represent dynamical systems with varying (i.e., liquid) time-constants coupled to their hidden state, with outputs being computed by numerical differential equation solvers. These neural networks exhibit stable and bounded behavior, yield superior expressivity within the family of neural ordinary differential equations, and give rise to improved performance on time-series prediction tasks. To demonstrate these properties, we first take a theoretical approach to find bounds over their dynamics, and compute their expressive power by the trajectory length measure in a latent trajectory space.

Such games are central in formal methods since they model the interaction between a non-terminating system and its environment. In bidding games the players bid for the right to move the token: in each round, the players simultaneously submit bids, and the higher bidder moves the token and pays the other player. Bidding games are known to have a clean and elegant mathematical structure that relies on the ability of the players to submit arbitrarily small bids. Many applications, however, require a fixed granularity for the bids, which can represent, for example, the monetary value expressed in cents. We study, for the first time, the combination of discrete-bidding and infinite-duration games. Our most important result proves that these games form a large determined subclass of concurrent games, where determinacy is the strong property that there always exists exactly one player who can guarantee winning the game. In particular, we show that, in contrast to non-discrete bidding games, the mechanism with which tied bids are resolved plays an important role in discrete-bidding games. We study several natural tie-breaking mechanisms and show that, while some do not admit determinacy, most natural mechanisms imply determinacy for every pair of initial budgets."}],"keyword":["computer science","computer science and game theory","logic in computer science"],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"date_updated":"2023-08-17T06:56:42Z","author":[{"last_name":"Aghajohari","full_name":"Aghajohari, Milad","first_name":"Milad"},{"id":"463C8BC2-F248-11E8-B48F-1D18A9856A87","first_name":"Guy","orcid":"0000-0001-5588-8287","full_name":"Avni, Guy","last_name":"Avni"},{"orcid":"0000-0002-2985-7724","full_name":"Henzinger, Thomas A","last_name":"Henzinger","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A"}],"status":"public"},{"title":"The Civl verifier","page":"143–152","quality_controlled":"1","conference":{"name":"FMCAD: Formal Methods in Computer-Aided Design","start_date":"2021-10-20","end_date":"2021-10-22","location":"Virtual"},"citation":{"mla":"Kragl, Bernhard, and Shaz Qadeer. “The Civl Verifier.” <i>Proceedings of the 21st Conference on Formal Methods in Computer-Aided Design</i>, edited by Piskac Ruzica and Michael W.

Traditionally, the players alternate turns in moving the token. In bidding games, however, the players have budgets, and in each turn, we hold an “auction” (bidding) to determine which player moves the token: both players simultaneously submit bids and the higher bidder moves the token. The bidding mechanisms differ in their payment schemes. Bidding games were largely studied with variants of first-price bidding in which only the higher bidder pays his bid. We focus on all-pay bidding, where both players pay their bids. Finite-duration all-pay bidding games were studied and shown to be technically more challenging than their first-price counterparts. We study for the first time, infinite-duration all-pay bidding games. Our most interesting results are for mean-payoff objectives: we portray a complete picture for games played on strongly-connected graphs. We study both pure (deterministic) and mixed (probabilistic) strategies and completely characterize the optimal and almost-sure (with probability 1) payoffs the players can respectively guarantee. We show that mean-payoff games under all-pay bidding exhibit the intriguing mathematical properties of their first-price counterparts; namely, an equivalence with random-turn games in which in each turn, the player who moves is selected according to a (biased) coin toss. The equivalences for all-pay bidding are more intricate and unexpected than for first-price bidding.","lang":"eng"}],"scopus_import":"1","date_updated":"2025-07-14T09:10:12Z","language":[{"iso":"eng"}],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","status":"public","author":[{"first_name":"Guy","id":"463C8BC2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5588-8287","last_name":"Avni","full_name":"Avni, Guy"},{"last_name":"Jecker","full_name":"Jecker, Ismael R","first_name":"Ismael R","id":"85D7C63E-7D5D-11E9-9C0F-98C4E5697425"},{"first_name":"Dorde","id":"294AA7A6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4681-1699","full_name":"Zikelic, Dorde","last_name":"Zikelic"}],"oa_version":"Preprint","type":"conference","publication_status":"published","external_id":{"arxiv":["2005.06636"]},"_id":"10694","publisher":"Society for Industrial and Applied Mathematics","department":[{"_id":"GradSch"},{"_id":"KrCh"}],"publication_identifier":{"isbn":["978-1-61197-646-5"]},"project":[{"grant_number":"Z211","call_identifier":"FWF","name":"The Wittgenstein Prize","_id":"25F42A32-B435-11E9-9278-68D0E5697425"},{"call_identifier":"H2020","name":"Formal Methods for Stochastic Models: Algorithms and Applications","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","grant_number":"863818"},{"grant_number":"665385","call_identifier":"H2020","name":"International IST Doctoral Program","_id":"2564DBCA-B435-11E9-9278-68D0E5697425"}],"year":"2021","month":"01"},{"month":"06","year":"2021","publication_identifier":{"eissn":["1570-5846"],"issn":["0010-437X"]},"isi":1,"article_type":"original","department":[{"_id":"TiBr"}],"publisher":"Cambridge University Press","external_id":{"isi":["000667289300001"],"arxiv":["1909.03266"]},"publication_status":"published","issue":"7","_id":"10711","oa_version":"Preprint","type":"journal_article","status":"public","author":[{"first_name":"Pascal","last_name":"Autissier","full_name":"Autissier, Pascal"},{"id":"6A459894-5FDD-11E9-AF35-BB24E6697425","first_name":"Dante","last_name":"Bonolis","full_name":"Bonolis, Dante"},{"last_name":"Lamzouri","full_name":"Lamzouri, Youness","first_name":"Youness"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"date_updated":"2023-08-17T06:59:16Z","main_file_link":[{"url":"https://arxiv.org/abs/1909.03266","open_access":"1"}],"keyword":["Algebra and Number Theory"],"abstract":[{"text":"In this paper, we investigate the distribution of the maximum of partial sums of families of  m -periodic complex-valued functions satisfying certain conditions.

So far, however, it has proven challenging to deal with microscopic models in which the total number of particles is not conserved. To address this issue, we propose a new variant of neural network states, which we term neural coherent states. Taking the Fröhlich impurity model as a case study, we show that neural coherent states can learn the ground state of non-additive systems very well. In particular, we observe substantial improvement over the standard coherent state estimates in the most challenging intermediate coupling regime.
