This problem has become popular in view of the emerging software and hardware support for executing models compressed via pruning and/or quantization with speedup, and well-performing solutions have been proposed independently for both compression approaches.In this paper, we introduce a new compression framework which covers both weight pruning and quantization in a unified setting, is time- and space-efficient, and considerably improves upon the practical performance of existing post-training methods. At the technical level, our approach is based on an exact and efficient realization of the classical Optimal Brain Surgeon (OBS) framework of [LeCun, Denker, and Solla, 1990] extended to also cover weight quantization at the scale of modern DNNs. From the practical perspective, our experimental results show that it can improve significantly upon the compression-accuracy trade-offs of existing post-training methods, and that it can enable the accurate compound application of both pruning and quantization in a post-training setting.","lang":"eng"}],"_id":"17087","language":[{"iso":"eng"}],"date_updated":"2026-04-07T12:43:03Z","corr_author":"1","oa_version":"Submitted Version","quality_controlled":"1","publisher":"ML Research Press","volume":35,"year":"2022","publication":"36th Conference on Neural Information Processing Systems","scopus_import":"1","intvolume":"        35","ddc":["000"],"acknowledgement":"We gratefully acknowledge funding from the European Research Council (ERC) under the European Union’s Horizon 2020 programme (grant agreement No 805223 ScaleML), as well as computational support from AWS EC2.

For cubical complexes, the two commonly used constructions (corresponding to direct and indirect digital adjacencies) can give different results for the same image. The two constructions are almost dual to each other, and we use this relationship to extend and modify the cubical complexes to become dual filtered cell complexes. We derive a general relationship between the persistent homology of two dual filtered cell complexes, and also establish how various modifications to a filtered complex change the persistence diagram. Applying these results to images, we derive a method to transform the persistence diagram computed using one type of cubical complex into a persistence diagram for the other construction. This means software for computing persistent homology from images can now be easily adapted to produce results for either of the two cubical complex constructions without additional low-level code implementation.","lang":"eng"}],"_id":"11440","related_material":{"record":[{"relation":"dissertation_contains","id":"18667","status":"public"}]},"month":"01","citation":{"mla":"Bleile, Bea, et al. “The Persistent Homology of Dual Digital Image Constructions.” <i>Research in Computational Topology 2</i>, edited by Ellen Gasparovic et al., 1st ed., vol. 30, Springer Nature, 2022, pp. 1–26, doi:<a href=\"https://doi.org/10.1007/978-3-030-95519-9_1\">10.1007/978-3-030-95519-9_1</a>.","ieee":"B.

We ask how quickly such a species changes its range in response to changed conditions. Szép et al. (Szép E, Sachdeva H, Barton NH. 2021 Polygenic local adaptation in metapopulations: a stochastic eco-evolutionary model. Evolution75, 1030–1045 (doi:10.1111/evo.14210)) used the infinite island model to find the stationary distribution of allele frequencies and deme sizes. We extend this to find how a metapopulation responds to changes in carrying capacity, selection strength, or migration rate when deme sizes are fixed. We further develop a ‘fixed-state’ approximation. Under this approximation, polymorphism is only possible for a narrow range of habitat proportions when selection is weak compared to drift, but for a much wider range otherwise. When rates of selection or migration relative to drift change in a single deme of the metapopulation, the population takes a time of order m−1 to reach the new equilibrium. However, even with many loci, there can be substantial fluctuations in net adaptation, because at each locus, alleles randomly get lost or fixed. Thus, in a finite metapopulation, variation may gradually be lost by chance, even if it would persist in an infinite metapopulation. When conditions change across the whole metapopulation, there can be rapid change, which is predicted well by the fixed-state approximation. This work helps towards an understanding of how metapopulations extend their range across diverse environments.\r\nThis article is part of the theme issue ‘Species’ ranges in the face of changing environments (Part II)’.","lang":"eng"}],"_id":"10787","keyword":["General Agricultural and Biological Sciences","General Biochemistry","Genetics and Molecular Biology"]},{"status":"public","isi":1,"has_accepted_license":"1","publication_identifier":{"eissn":["1471-2970"],"issn":["0962-8436"]},"day":"24","department":[{"_id":"GradSch"},{"_id":"NiBa"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","article_processing_charge":"No","external_id":{"isi":["000745854300008"],"pmid":["35067097"]},"publication_status":"published","file_date_updated":"2022-01-24T10:34:45Z","article_type":"original","project":[{"grant_number":"P32896","_id":"c08d3278-5a5b-11eb-8a69-fdb09b55f4b8","name":"Causes and consequences of population fragmentation"}],"date_published":"2022-01-24T00:00:00Z","file":[{"date_updated":"2022-01-24T10:34:45Z","relation":"main_file","checksum":"04ca9e2f0e344d680b947f2457df8d0a","content_type":"application/pdf","access_level":"open_access","file_id":"10659","file_name":"rstb.2021.0010.pdf","creator":"oolusany","date_created":"2022-01-24T10:34:45Z","file_size":1845792}],"issue":"1846","title":"Genetic load and extinction in peripheral populations: The roles of migration, drift and demographic stochasticity","date_created":"2022-01-24T10:34:53Z","author":[{"last_name":"Sachdeva","full_name":"Sachdeva, Himani","first_name":"Himani"},{"id":"41AD96DC-F248-11E8-B48F-1D18A9856A87","last_name":"Olusanya","orcid":"0000-0003-1971-8314","first_name":"Oluwafunmilola O","full_name":"Olusanya, Oluwafunmilola O"},{"first_name":"Nicholas H","full_name":"Barton, Nicholas H","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","last_name":"Barton","orcid":"0000-0002-8548-5240"}],"article_number":"20210010","intvolume":"       377","ddc":["576"],"acknowledgement":"This research was partly funded by the Austrian Science Fund (FWF) (grant no.

Our analysis shows that migration can have qualitatively different effects, depending on the total mutation target and fitness effects of deleterious variants. In particular, we find that populations exhibit a genetic Allee effect across a wide range of parameter combinations, when variants are partially recessive, cycling between low-load (large-population) and high-load (sink) states. Increased migration reduces load in the sink state (by increasing heterozygosity) but further inflates load in the large-population state (by hindering purging). We identify various critical parameter thresholds at which one or other stable state collapses, and discuss how these thresholds are influenced by the genetic versus demographic effects of migration. Our analysis is based on a ‘semi-deterministic’ analysis, which accounts for genetic drift but neglects demographic stochasticity. We also compare against simulations which account for both demographic stochasticity and drift. Our results clarify the importance of gene flow as a key determinant of extinction risk in peripheral populations, even in the absence of ecological gradients.

This can be quantified as the Kullback–Leibler (KL) divergence between the actual distribution of genotype frequencies and the corresponding neutral distribution. First, we show that this population-level information sets an upper bound on the information at the level of genotype and phenotype, limiting how precisely they can be specified by selection. Next, we study how the accumulation and maintenance of information is limited by the cost of selection, measured as the genetic load or the relative fitness variance, both of which we connect to the control-theoretic KL cost of control. The information accumulation rate is upper bounded by the population size times the cost of selection. This bound is very general, and applies across models (Wright–Fisher, Moran, diffusion) and to arbitrary forms of selection, mutation, and recombination. Finally, the cost of maintaining information depends on how it is encoded: Specifying a single allele out of two is expensive, but one bit encoded among many weakly specified loci (as in a polygenic trait) is cheap.","lang":"eng"}],"oa":1,"month":"08","citation":{"ama":"Hledik M, Barton NH, Tkačik G.

It is a challenging problem to construct a protocol with similar security guarantees that can efficiently scale to large groups. A major bottleneck are the frequent key rotations users need to perform to achieve post compromise forward security.\r\n\r\nIn current proposals – most notably in TreeKEM (which is part of the IETF’s Messaging Layer Security (MLS) protocol draft) – for users in a group of size n to rotate their keys, they must each craft a message of size log(n) to be broadcast to the group using an (untrusted) delivery server.\r\n\r\nIn larger groups, having users sequentially rotate their keys requires too much bandwidth (or takes too long), so variants allowing any T≤n users to simultaneously rotate their keys in just 2 communication rounds have been suggested (e.g. “Propose and Commit” by MLS). Unfortunately, 2-round concurrent updates are either damaging or expensive (or both); i.e. they either result in future operations being more costly (e.g. via “blanking” or “tainting”) or are costly themselves requiring Ω(T) communication for each user [Bienstock et al., TCC’20].\r\n\r\nIn this paper we propose CoCoA; a new scheme that allows for T concurrent updates that are neither damaging nor costly. That is, they add no cost to future operations yet they only require Ω(log2(n)) communication per user. To circumvent the [Bienstock et al.] lower bound, CoCoA increases the number of rounds needed to complete all updates from 2 up to (at most) log(n); though typically fewer rounds are needed.\r\n\r\nThe key insight of our protocol is the following: in the (non-concurrent version of) TreeKEM, a delivery server which gets T concurrent update requests will approve one and reject the remaining T−1. In contrast, our server attempts to apply all of them. If more than one user requests to rotate the same key during a round, the server arbitrarily picks a winner. Surprisingly, we prove that regardless of how the server chooses the winners, all previously compromised users will recover after at most log(n) such update rounds.\r\n\r\nTo keep the communication complexity low, CoCoA is a server-aided CGKA. That is, the delivery server no longer blindly forwards packets, but instead actively computes individualized packets tailored to each user. As the server is untrusted, this change requires us to develop new mechanisms ensuring robustness of the protocol.","lang":"eng"}],"conference":{"end_date":"2022-06-03","name":"EUROCRYPT: Theory and Applications of Cryptology and Information Security","start_date":"2022-05-30","location":"Trondheim, Norway"},"page":"815–844","oa":1,"related_material":{"record":[{"relation":"dissertation_contains","id":"18088","status":"public"}]},"month":"05","type":"conference","citation":{"ieee":"J.

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."}],"_id":"12780","citation":{"mla":"Markov, Ilia, et al. “CGX: Adaptive System Support for Communication-Efficient Deep Learning.” <i>Proceedings of the 23rd ACM/IFIP International Middleware Conference</i>, Association for Computing Machinery, 2022, pp. 241–54, doi:<a href=\"https://doi.org/10.1145/3528535.3565248\">10.1145/3528535.3565248</a>.","ieee":"I.

However, generalisation of these findings is limited due to scarceness of systematic data on fitness landscapes of proteins with a defined evolutionary relationship. We characterized the fitness peaks of four orthologous fluorescent proteins with a broad range of sequence divergence. While two of the four studied fitness peaks were sharp, the other two were considerably flatter, being almost entirely free of epistatic interactions. Mutationally robust proteins, characterized by a flat fitness peak, were not optimal templates for machine-learning-driven protein design – instead, predictions were more accurate for fragile proteins with epistatic landscapes. Our work paves insights for practical application of fitness landscape heterogeneity in protein engineering.","lang":"eng"}],"keyword":["General Immunology and Microbiology","General Biochemistry","Genetics and Molecular Biology","General Medicine","General Neuroscience"],"_id":"11448","acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"Bio"}],"date_updated":"2026-04-07T13:25:01Z","language":[{"iso":"eng"}],"tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"corr_author":"1","oa_version":"Published Version","quality_controlled":"1","publisher":"eLife Sciences Publications","file":[{"date_updated":"2022-06-20T07:44:19Z","relation":"main_file","access_level":"open_access","file_id":"11454","success":1,"content_type":"application/pdf","checksum":"7573c28f44028ab0cc81faef30039e44","file_name":"2022_eLife_Somermeyer.pdf","creator":"dernst","date_created":"2022-06-20T07:44:19Z","file_size":5297213}],"ec_funded":1,"author":[{"first_name":"Louisa","full_name":"Gonzalez Somermeyer, Louisa","id":"4720D23C-F248-11E8-B48F-1D18A9856A87","last_name":"Gonzalez Somermeyer","orcid":"0000-0001-9139-5383"},{"full_name":"Fleiss, Aubin","first_name":"Aubin","last_name":"Fleiss"},{"last_name":"Mishin","full_name":"Mishin, Alexander S","first_name":"Alexander S"},{"full_name":"Bozhanova, Nina G","first_name":"Nina G","last_name":"Bozhanova"},{"first_name":"Anna A","full_name":"Igolkina, Anna A","last_name":"Igolkina"},{"first_name":"Jens","full_name":"Meiler, Jens","last_name":"Meiler"},{"last_name":"Alaball Pujol","first_name":"Maria-Elisenda","full_name":"Alaball Pujol, Maria-Elisenda"},{"last_name":"Putintseva","full_name":"Putintseva, Ekaterina V","first_name":"Ekaterina V"},{"full_name":"Sarkisyan, Karen S","first_name":"Karen S","last_name":"Sarkisyan"},{"orcid":"0000-0001-8243-4694","id":"44FDEF62-F248-11E8-B48F-1D18A9856A87","last_name":"Kondrashov","full_name":"Kondrashov, Fyodor","first_name":"Fyodor"}],"article_number":"75842","date_created":"2022-06-18T09:06:59Z","title":"Heterogeneity of the GFP fitness landscape and data-driven protein design","article_type":"original","project":[{"call_identifier":"H2020","name":"Characterizing the fitness landscape on population and global scales","_id":"26580278-B435-11E9-9278-68D0E5697425","grant_number":"771209"},{"_id":"2564DBCA-B435-11E9-9278-68D0E5697425","grant_number":"665385","name":"International IST Doctoral Program","call_identifier":"H2020"}],"date_published":"2022-05-05T00:00:00Z","volume":11,"year":"2022","publication":"eLife","pmid":1,"scopus_import":"1","intvolume":"        11","ddc":["570"],"acknowledgement":"We thank Ondřej Draganov, Rodrigo Redondo, Bor Kavčič, Mia Juračić and Andrea Pauli for discussion and technical advice.

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"}],"oa":1,"page":"78-88","type":"journal_article","citation":{"mla":"Liu, Yu, et al. “Defect Engineering in Solution-Processed Polycrystalline SnSe Leads to High Thermoelectric Performance.” <i>ACS Nano</i>, vol. 16, no. 1, American Chemical Society , 2022, pp. 78–88, doi:<a href=\"https://doi.org/10.1021/acsnano.1c06720\">10.1021/acsnano.1c06720</a>.","ieee":"Y.

Recently the fate of a localized system coupled to a thermalizing system viewed as a quantum bath received significant theoretical and experimental attention. In this work, we study a mobile impurity, representing a small quantum bath, that interacts locally with an Anderson insulator with a finite density of localized particles. Using static Hartree approximation to obtain an effective disorder strength, we formulate an analytic criterion for the perturbative stability of the localization. Next, we use an approximate dynamical Hartree method and the quasi-exact time-evolved block decimation (TEBD) algorithm to study the dynamics of the system. We find that the dynamical Hartree approach which completely ignores entanglement between the impurity and localized particles predicts the delocalization of the system. In contrast, the full numerical simulation of the unitary dynamics with TEBD suggests the stability of localization on numerically accessible timescales. Finally, using an extension of the density matrix renormalization group algorithm to excited states (DMRG-X), we approximate the highly excited eigenstates of the system. We find that the impurity remains localized in the eigenstates and entanglement is enhanced in a finite region around the position of the impurity, confirming the dynamical predictions. Dynamics and the DMRG-X results provide compelling evidence for the stability of localization."}],"oa":1,"month":"06","citation":{"ieee":"P. Brighi, A. Michailidis, K. Kirova, D. A. Abanin, and M.
