While graphs represent the most basic planning model, MDPs represent interaction with nature and games on graphs represent interaction with an adversarial environment. We consider two planning problems where there are k different target sets, and the problems are as follows: (a) the coverage problem asks whether there is a plan for each individual target set; and (b) the sequential target reachability problem asks whether the targets can be reached in sequence. For the coverage problem, we present a linear-time algorithm for graphs, and quadratic conditional lower bound for MDPs and games on graphs. For the sequential target problem, we present a linear-time algorithm for graphs, a sub-quadratic algorithm for MDPs, and a quadratic conditional lower bound for games on graphs. Our results with conditional lower bounds establish (i) model-separation results showing that for the coverage problem MDPs and games on graphs are harder than graphs and for the sequential reachability problem games on graphs are harder than MDPs and graphs; and (ii) objective-separation results showing that for MDPs the coverage problem is harder than the sequential target problem.","lang":"eng"}],"type":"conference","language":[{"iso":"eng"}],"conference":{"start_date":"2018-06-24","location":"Delft, Netherlands","end_date":"2018-06-29","name":"ICAPS: International Conference on Automated Planning and Scheduling"},"project":[{"name":"Rigorous Systems Engineering","call_identifier":"FWF","_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23"},{"_id":"2581B60A-B435-11E9-9278-68D0E5697425","grant_number":"279307","name":"Quantitative Graph Games: Theory and Applications","call_identifier":"FP7"}],"isi":1,"quality_controlled":"1","oa":1,"external_id":{"isi":["000492986200007"],"arxiv":["1804.07031"]},"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1804.07031"}],"month":"06","date_created":"2018-12-11T11:44:17Z","date_updated":"2023-09-26T10:41:41Z","related_material":{"record":[{"id":"9293","status":"public","relation":"later_version"}]},"author":[{"full_name":"Chatterjee, Krishnendu","first_name":"Krishnendu","last_name":"Chatterjee","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X"},{"full_name":"Dvorák, Wolfgang","last_name":"Dvorák","first_name":"Wolfgang"},{"full_name":"Henzinger, Monika H","id":"540c9bbd-f2de-11ec-812d-d04a5be85630","orcid":"0000-0002-5008-6530","first_name":"Monika H","last_name":"Henzinger"},{"full_name":"Svozil, Alexander","last_name":"Svozil","first_name":"Alexander"}],"department":[{"_id":"KrCh"}],"publisher":"AAAI Press","publication_status":"published","year":"2018","publist_id":"8020","ec_funded":1},{"scopus_import":"1","has_accepted_license":"1","article_processing_charge":"No","day":"01","page":"166 - 207","citation":{"ista":"Chatterjee K, Pavlogiannis A, Kößler A, Schmid U. 2018.

Given such a taskset T , the competitive ratio of an on-line scheduling algorithm A for T is the worst-case utility ratio of A over the utility achieved by a clairvoyant algorithm. We leverage the theory of quantitative graph games to address the competitive analysis and competitive synthesis problems. For the competitive analysis case, given any taskset T and any finite-memory on- line scheduling algorithm A , we show that the competitive ratio of A in T can be computed in polynomial time in the size of the state space of A . Our approach is flexible as it also provides ways to model meaningful constraints on the released task sequences that determine the competitive ratio. We provide an experimental study of many well-known on-line scheduling algorithms, which demonstrates the feasibility of our competitive analysis approach that effectively replaces human ingenuity (required Preliminary versions of this paper have appeared in Chatterjee et al.

For the competitive synthesis case, we are just given a taskset T , and the goal is to automatically synthesize an opti- mal on-line scheduling algorithm A , i.e., one that guarantees the largest competitive ratio possible for T . We show how the competitive synthesis problem can be reduced to a two-player graph game with partial information, and establish that the compu- tational complexity of solving this game is Np -complete. The competitive synthesis problem is hence in Np in the size of the state space of the non-deterministic labeled transition system encoding the taskset. Overall, the proposed framework assists in the selection of suitable scheduling algorithms for a given taskset, which is in fact the most common situation in real-time systems design.

Whereas for bosons a point interacting system is always unstable this ques- tion is more subtle for a gas of two species of fermions. In particular the answer depends on the mass ratio between these two species. Most of this work will be focused on the N + M model which consists of two species of fermions with N, M particles respectively which interact via point interactions. We will introduce this model using a formal limit and discuss the N + 1 system in more detail. In particular, we will show that for mass ratios above a critical one, which does not depend on the particle number, the N + 1 system is stable. In the context of this model we will prove rigorous versions of Tan relations which relate various quantities of the point-interacting model. By restricting the N + 1 system to a box we define a finite density model with point in- teractions. In the context of this system we will discuss the energy change when introducing a point-interacting impurity into a system of non-interacting fermions. We will see that this change in energy is bounded independently of the particle number and in particular the bound only depends on the density and the scattering length. As another special case of the N + M model we will show stability of the 2 + 2 model for mass ratios in an interval around one. Further we will investigate a different model of point interactions which was discussed before in the literature and which is, contrary to the N + M model, not given by a limiting procedure but is based on a Dirichlet form. We will show that this system behaves trivially in the thermodynamic limit, i.e. the free energy per particle is the same as the one of the non-interacting system."}],"project":[{"_id":"25C878CE-B435-11E9-9278-68D0E5697425","grant_number":"P27533_N27","name":"Structure of the Excitation Spectrum for Many-Body Quantum Systems","call_identifier":"FWF"}],"oa":1,"language":[{"iso":"eng"}],"degree_awarded":"PhD","supervisor":[{"full_name":"Seiringer, Robert","first_name":"Robert","last_name":"Seiringer","id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6781-0521"}],"doi":"10.15479/AT:ISTA:th_1043","publication_identifier":{"issn":["2663-337X"]},"month":"09","department":[{"_id":"RoSe"}],"publisher":"Institute of Science and Technology Austria","publication_status":"published","year":"2018","date_updated":"2023-09-27T12:34:14Z","date_created":"2018-12-11T11:44:22Z","related_material":{"record":[{"status":"public","relation":"part_of_dissertation","id":"5856"},{"status":"public","relation":"part_of_dissertation","id":"154"},{"id":"1198","relation":"part_of_dissertation","status":"public"},{"relation":"part_of_dissertation","status":"public","id":"741"}]},"author":[{"last_name":"Moser","first_name":"Thomas","id":"2B5FC9A4-F248-11E8-B48F-1D18A9856A87","full_name":"Moser, Thomas"}],"publist_id":"8002","file_date_updated":"2020-07-14T12:46:37Z"},{"oa":1,"external_id":{"isi":["000424842400019"]},"quality_controlled":"1","isi":1,"project":[{"call_identifier":"FP7","name":"Polarity and subcellular dynamics in plants","grant_number":"282300","_id":"25716A02-B435-11E9-9278-68D0E5697425"}],"doi":"10.1242/jcs.204198","language":[{"iso":"eng"}],"month":"01","publication_identifier":{"issn":["00219533"]},"year":"2018","publication_status":"published","department":[{"_id":"JiFr"}],"publisher":"Company of Biologists","author":[{"full_name":"Tejos, Ricardo","first_name":"Ricardo","last_name":"Tejos"},{"last_name":"Rodríguez Furlán","first_name":"Cecilia","full_name":"Rodríguez Furlán, Cecilia"},{"id":"45F536D2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6463-5257","first_name":"Maciek","last_name":"Adamowski","full_name":"Adamowski, Maciek"},{"last_name":"Sauer","first_name":"Michael","full_name":"Sauer, Michael"},{"last_name":"Norambuena","first_name":"Lorena","full_name":"Norambuena, Lorena"},{"full_name":"Friml, Jirí","orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87","last_name":"Friml","first_name":"Jirí"}],"date_updated":"2023-09-26T15:47:50Z","date_created":"2018-12-11T11:49:10Z","volume":131,"article_number":"jcs.204198","file_date_updated":"2020-07-14T12:48:15Z","publist_id":"6530","ec_funded":1,"publication":"Journal of Cell Science","citation":{"chicago":"Tejos, Ricardo, Cecilia Rodríguez Furlán, Maciek Adamowski, Michael Sauer, Lorena Norambuena, and Jiří Friml. “PATELLINS Are Regulators of Auxin Mediated PIN1 Relocation and Plant Development in Arabidopsis Thaliana.” Journal of Cell Science.

In plants, a directional distribution of the plant hormone auxin is at the core of many developmental programs. A feedback regulation of auxin on the polarized localization of PIN auxin transporters in individual cells has been proposed as a self-organizing mechanism for coordinated tissue polarization, but the molecular mechanisms linking auxin signalling to PIN-dependent auxin transport remain unknown. We performed a microarray-based approach to find regulators of the auxin-induced PIN relocation in the Arabidopsis thaliana root. We identified a subset of a family of phosphatidylinositol transfer proteins (PITP), the PATELLINs (PATL). Here, we show that PATLs are expressed in partially overlapping cells types in different tissues going through mitosis or initiating differentiation programs. PATLs are plasma membrane-associated proteins accumulated in Arabidopsis embryos, primary roots, lateral root primordia, and developing stomata. Higher order patl mutants display reduced PIN1 repolarization in response to auxin, shorter root apical meristem, and drastic defects in embryo and seedling development. This suggests PATLs redundantly play a crucial role in polarity and patterning in Arabidopsis.","lang":"eng"}],"issue":"2"},{"oa":1,"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"supervisor":[{"orcid":"0000-0001-8342-202X","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","last_name":"Katsaros","first_name":"Georgios","full_name":"Katsaros, Georgios"}],"degree_awarded":"PhD","language":[{"iso":"eng"}],"doi":"10.15479/AT:ISTA:TH_1047","month":"09","publication_identifier":{"issn":["2663-337X"]},"publication_status":"published","department":[{"_id":"GeKa"},{"_id":"GradSch"}],"publisher":"Institute of Science and Technology Austria","year":"2018","date_updated":"2023-09-26T15:50:22Z","date_created":"2018-12-11T11:44:28Z","author":[{"full_name":"Vukušić, Lada","id":"31E9F056-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2424-8636","first_name":"Lada","last_name":"Vukušić"}],"related_material":{"record":[{"id":"23","status":"public","relation":"part_of_dissertation"},{"id":"840","relation":"part_of_dissertation","status":"public"}]},"file_date_updated":"2020-07-14T12:47:44Z","publist_id":"7985","page":"103","citation":{"chicago":"Vukušić, Lada. “Charge Sensing and Spin Relaxation Times of Holes in Ge Hut Wires.” Institute of Science and Technology Austria, 2018. https://doi.org/10.15479/AT:ISTA:TH_1047.","mla":"Vukušić, Lada.

Still, to be used for computation, it has to fulfill criteria. Qubits, regardless of the system in which they are realized, suffer from decoherence. This leads to loss of the information stored in the qubit. The upper bound of the time scale on which decoherence happens is set by the spin relaxation time. In this thesis I studied a two-level system consisting of a Zeeman-split hole spin confined in a quantum dot formed in a Ge hut wire. Such Ge hut wires have emerged as a promising material system for the realization of spin qubits, due to the combination of two significant properties: long spin coherence time as expected for group IV semiconductors due to the low hyperfine interaction and a strong valence band spin-orbit coupling. Here, I present how to fabricate quantum dot devices suitable for electrical transport measurements. Coupled quantum dot devices allowed the realization of a charge sensor, which is electrostatically and tunnel coupled to a quantum dot. By integrating the charge sensor into a radio-frequency reflectometry setup, I performed for the first time single-shot readout measurements of hole spins and extracted the hole spin relaxation times in Ge hut wires.","lang":"eng"}]},{"publication_identifier":{"issn":["2663-337X"]},"month":"03","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"language":[{"iso":"eng"}],"degree_awarded":"PhD","supervisor":[{"id":"353C1B58-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5001-4804","first_name":"Peter M","last_name":"Jonas","full_name":"Jonas, Peter M"}],"doi":"10.15479/AT:ISTA:th_997","publist_id":"7541","file_date_updated":"2020-07-14T12:46:04Z","publisher":"Institute of Science and Technology Austria","department":[{"_id":"PeJo"}],"publication_status":"published","year":"2018","date_created":"2018-12-11T11:45:49Z","date_updated":"2023-09-27T12:26:03Z","related_material":{"record":[{"id":"1117","status":"public","relation":"part_of_dissertation"},{"id":"749","status":"public","relation":"part_of_dissertation"}]},"author":[{"first_name":"Chong","last_name":"Chen","id":"3DFD581A-F248-11E8-B48F-1D18A9856A87","full_name":"Chen, Chong"}],"article_processing_charge":"No","has_accepted_license":"1","day":"01","page":"110","citation":{"ama":"Chen C.

Although these interneurons only represent 10–20% of the whole population, they mediate feedback and feedforward inhibition and are involved in the generation of high-frequency network oscillations. A hallmark functional property of GABAergic interneurons, especially of the parvalbumin‑expressing (PV+) subtypes, is the speed of signaling at their output synapse across species and brain regions. Several molecular and subcellular factors may underlie the submillisecond signaling at GABAergic synapses. Such as the selective use of P/Q type Ca2+ channels and the tight coupling between Ca2+ channels and Ca2+ sensors of exocytosis. However, whether the molecular identity of the release sensor contributes to these signaling properties remains unclear. Besides, these interneurons are mainly show depression in response to train of stimuli. How could they keep sufficient release to control the activity of postsynaptic principal neurons during high network activity, is largely elusive. For my Ph.D. work, we firstly examined the Ca2+ sensor of exocytosis at the GABAergic basket cell (BC) to Purkinje cell (PC) synapse in the cerebellum. Immunolabeling suggested that BC terminals selectively expressed synaptotagmin 2 (Syt2), whereas synaptotagmin 1 (Syt1) was enriched in excitatory terminals. Genetic elimination of Syt2 reduced action potential-evoked release to ~10% compared to the wild-type control, identifying Syt2 as the major Ca2+ sensor at BC‑PC synapses. Differential adenovirus-mediated rescue revealed Syt2 triggered release with shorter latency and higher temporal precision, and mediated faster vesicle pool replenishment than Syt1. Furthermore, deletion of Syt2 severely reduced and delayed disynaptic inhibition following parallel fiber stimulation. Thus, the selective use of Syt2 as the release sensor at BC–PC synapse ensures fast feedforward inhibition in cerebellar microcircuits. Additionally, we tested the function of another synaptotagmin member, Syt7, for inhibitory synaptic transmission at the BC–PC synapse. Syt7 is thought to be a Ca2+ sensor that mediates asynchronous transmitter release and facilitation at synapses. However, it is strongly expressed in fast-spiking, PV+ GABAergic interneurons and the output synapses of these neurons produce only minimal asynchronous release and show depression rather than facilitation. How could Syt7, a facilitation sensor, contribute to the depressed inhibitory synaptic transmission needs to be further investigated and understood. Our results indicated that at the BC–PC synapse, Syt7 contributes to asynchronous release, pool replenishment and facilitation. In combination, these three effects ensure efficient transmitter release during high‑frequency activity and guarantee frequency independence of inhibition. Taken together, our results confirmed that Syt2, which has the fastest kinetic properties among all synaptotagmin members, is mainly used by the inhibitory BC‑PC synapse for synaptic transmission, contributing to the speed and temporal precision of transmitter release. Furthermore, we showed that Syt7, another highly expressed synaptotagmin member in the output synapses of cerebellar BCs, is used for ensuring efficient inhibitor synaptic transmission during high activity."}],"title":"Synaptotagmins ensure speed and efficiency of inhibitory neurotransmitter release","ddc":["571"],"status":"public","_id":"324","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","file":[{"access_level":"open_access","file_name":"IST-2018-997-v1+1_Thesis_chong_a.pdf","content_type":"application/pdf","file_size":8719458,"creator":"system","relation":"main_file","file_id":"5046","checksum":"8e163ae9e927401b9fa7c1b3e6a3631a","date_updated":"2020-07-14T12:46:04Z","date_created":"2018-12-12T10:13:58Z"},{"content_type":"application/octet-stream","file_size":47841940,"creator":"dernst","file_name":"2018_Thesis_chong_source.pages","access_level":"closed","date_created":"2019-04-05T09:25:26Z","date_updated":"2020-07-14T12:46:04Z","checksum":"f7d7260029a5fbb5c982db61328ade52","relation":"source_file","file_id":"6221"}],"oa_version":"Published Version","pubrep_id":"997"},{"issue":"1","abstract":[{"text":"We give a detailed and easily accessible proof of Gromov’s Topological Overlap Theorem.

In our previous work [C. J. Turner et al., Nat. Phys. 14, 745 (2018)], such dynamics was attributed to the existence of “quantum scarred” eigenstates in the many-body spectrum of the experimentally realized model. Here, we present a detailed study of the eigenstate properties of the same model. We find that the majority of the eigenstates exhibit anomalous thermalization: the observable expectation values converge to their Gibbs ensemble values, but parametrically slower compared to the predictions of the eigenstate thermalization hypothesis (ETH). Amidst the thermalizing spectrum, we identify nonergodic eigenstates that strongly violate the ETH, whose number grows polynomially with system size. Previously, the same eigenstates were identified via large overlaps with certain product states, and were used to explain the revivals observed in experiment. Here, we find that these eigenstates, in addition to highly atypical expectation values of local observables, also exhibit subthermal entanglement entropy that scales logarithmically with the system size. Moreover, we identify an additional class of quantum scarred eigenstates, and discuss their manifestations in the dynamics starting from initial product states. We use forward scattering approximation to describe the structure and physical properties of quantum scarred eigenstates. Finally, we discuss the stability of quantum scars to various perturbations. We observe that quantum scars remain robust when the introduced perturbation is compatible with the forward scattering approximation. In contrast, the perturbations which most efficiently destroy quantum scars also lead to the restoration of “canonical” thermalization.","lang":"eng"}],"issue":"15","type":"journal_article","oa_version":"Preprint","_id":"44","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","title":"Quantum scarred eigenstates in a Rydberg atom chain: Entanglement, breakdown of thermalization, and stability to perturbations","intvolume":" 98","month":"10","doi":"10.1103/PhysRevB.98.155134","acknowledged_ssus":[{"_id":"ScienComp"}],"language":[{"iso":"eng"}],"external_id":{"arxiv":["1806.10933"],"isi":["000447919100001"]},"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1806.10933"}],"oa":1,"quality_controlled":"1","isi":1,"publist_id":"8010","article_number":"155134","author":[{"full_name":"Turner, C J","last_name":"Turner","first_name":"C J"},{"last_name":"Michailidis","first_name":"Alexios","orcid":"0000-0002-8443-1064","id":"36EBAD38-F248-11E8-B48F-1D18A9856A87","full_name":"Michailidis, Alexios"},{"full_name":"Abanin, D A","first_name":"D A","last_name":"Abanin"},{"orcid":"0000-0002-2399-5827","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","last_name":"Serbyn","first_name":"Maksym","full_name":"Serbyn, Maksym"},{"full_name":"Papić, Z","first_name":"Z","last_name":"Papić"}],"date_updated":"2023-10-10T13:28:49Z","date_created":"2018-12-11T11:44:19Z","volume":98,"year":"2018","publication_status":"published","publisher":"American Physical Society","department":[{"_id":"MaSe"}]},{"title":"Exceeding the asymptotic limit of polymer drag reduction","status":"public","intvolume":" 120","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"328","oa_version":"Preprint","type":"journal_article","abstract":[{"lang":"eng","text":"The drag of turbulent flows can be drastically decreased by adding small amounts of high molecular weight polymers.

Contrary to this accepted view, we show that, for an appropriate choice of parameters, polymers can reduce the drag beyond the suggested asymptotic limit, eliminating turbulence and giving way to laminar flow. At higher polymer concentrations, however, the laminar state becomes unstable, resulting in a fluctuating flow with the characteristic drag of the MDR asymptote.

In this article, we present a combined experimental and numerical study exploring the dynamical role of unstable equilibrium solutions and their invariant manifolds in a weakly turbulent, electromagnetically driven, shallow fluid layer. Identifying instants when turbulent evolution slows down, we compute 31 unstable equilibria of a realistic two-dimensional model of the flow. We establish the dynamical relevance of these unstable equilibria by showing that they are closely visited by the turbulent flow. We also establish the dynamical relevance of unstable manifolds by verifying that they are shadowed by turbulent trajectories departing from the neighborhoods of unstable equilibria over large distances in state space.","lang":"eng"}],"issue":"2","type":"journal_article","oa_version":"Submitted Version","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"136","title":"Unstable equilibria and invariant manifolds in quasi-two-dimensional Kolmogorov-like flow","status":"public","intvolume":" 98","day":"13","article_processing_charge":"No","scopus_import":"1","date_published":"2018-08-13T00:00:00Z","publication":"Physical Review E","citation":{"ama":"Suri B, Tithof J, Grigoriev R, Schatz M.

Patient fibroblasts were used to study splicing defect and zebrafish to model the disease.\r\n\r\nResults: We identified six individuals from three unrelated families with a founder homozygous splice mutation in TRAPPC6B, encoding a core subunit of the complex TRAPP I. Patients manifested a neurodevelopmental disorder characterised by microcephaly, epilepsy and autistic features, and showed splicing defect.

After HPF, samples are maintained at low temperature during dehydration and fixation, while avoiding damaging recrystallization. This is a notoriously slow process. McDonald and Webb demonstrated, in 2011, that sample agitation during FS dramatically reduces the necessary time. Then, in 2015, we (H.G. and S.R.) introduced an agitation module into the cryochamber of an automated FS unit and demonstrated that the preparation of algae could be shortened from days to a couple of hours. We argued that variability in the processing, reproducibility, and safety issues are better addressed using automated FS units. For dissemination, we started low-cost manufacturing of agitation modules for two of the most widely used FS units, the Automatic Freeze Substitution Systems, AFS(1) and AFS2, from Leica Microsystems, using three dimensional (3D)-printing of the major components. To test them, several labs independently used the modules on a wide variety of specimens that had previously been processed by manual agitation, or without agitation. We demonstrate that automated processing with sample agitation saves time, increases flexibility with respect to sample requirements and protocols, and produces data of at least as good quality as other approaches.","lang":"eng"}],"issue":"12","type":"journal_article","oa_version":"Published Version","title":"Agitation modules: Flexible means to accelerate automated freeze substitution","status":"public","intvolume":" 66","_id":"163","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"related_material":{"link":[{"url":"https://ist.ac.at/en/news/first-machine-learning-method-capable-of-accurate-extrapolation/","relation":"press_release","description":"News on IST Homepage"}]},"author":[{"full_name":"Sahoo, Subham","first_name":"Subham","last_name":"Sahoo"},{"full_name":"Lampert, Christoph","id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8622-7887","first_name":"Christoph","last_name":"Lampert"},{"last_name":"Martius","first_name":"Georg S","id":"3A276B68-F248-11E8-B48F-1D18A9856A87","full_name":"Martius, Georg S"}],"volume":80,"date_updated":"2023-10-17T09:50:53Z","date_created":"2019-02-14T15:21:07Z","year":"2018","publisher":"ML Research Press","department":[{"_id":"ChLa"}],"publication_status":"published","ec_funded":1,"conference":{"name":"ICML: International Conference on Machine Learning","end_date":"2018-07-15","location":"Stockholm, Sweden","start_date":"2018-07-10"},"language":[{"iso":"eng"}],"oa":1,"external_id":{"isi":["000683379204058"],"arxiv":["1806.07259"]},"main_file_link":[{"url":"https://arxiv.org/abs/1806.07259","open_access":"1"}],"project":[{"grant_number":"291734","_id":"25681D80-B435-11E9-9278-68D0E5697425","name":"International IST Postdoc Fellowship Programme","call_identifier":"FP7"}],"quality_controlled":"1","isi":1,"month":"02","oa_version":"Preprint","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"6012","intvolume":" 80","status":"public","title":"Learning equations for extrapolation and control","abstract":[{"text":"We present an approach to identify concise equations from data using a shallow neural network approach.

This is in contrast to previous distribution-free algorithmic stability results for SGD which depend on the worst-case constants. By virtue of the data-dependent argument, our bounds provide new insights into learning with SGD on convex and non-convex problems. In the convex case, we show that the bound on the generalization error depends on the risk at the initialization point. In the non-convex case, we prove that the expected curvature of the objective function around the initialization point has crucial influence on the generalization error. In both cases, our results suggest a simple data-driven strategy to stabilize SGD by pre-screening its initialization. As a corollary, our results allow us to show optimistic generalization bounds that exhibit fast convergence rates for SGD subject to a vanishing empirical risk and low noise of stochastic gradient.

Several families of communication-reduction methods, such as quantization, large-batch methods, and gradient sparsification, have been proposed. To date, gradient sparsification methods--where each node sorts gradients by magnitude, and only communicates a subset of the components, accumulating the rest locally--are known to yield some of the largest practical gains. Such methods can reduce the amount of communication per step by up to \\emph{three orders of magnitude}, while preserving model accuracy. Yet, this family of methods currently has no theoretical justification. This is the question we address in this paper. We prove that, under analytic assumptions, sparsifying gradients by magnitude with local error correction provides convergence guarantees, for both convex and non-convex smooth objectives, for data-parallel SGD. The main insight is that sparsification methods implicitly maintain bounds on the maximum impact of stale updates, thanks to selection by magnitude. Our analysis and empirical validation also reveal that these methods do require analytical conditions to converge well, justifying existing heuristics.","lang":"eng"}],"type":"conference","date_published":"2018-12-01T00:00:00Z","page":"5973-5983","citation":{"ista":"Alistarh D-A, Hoefler T, Johansson M, Konstantinov NH, Khirirat S, Renggli C. 2018.

We tested this hypothesis experimentally in the ant Lasius niger using a combination of automated tracking, controlled pathogen exposure, transmission quantification, and temporally explicit simulations. Pathogen exposure induced behavioral changes in both exposed ants and their nestmates, which helped contain the disease by reinforcing key transmission-inhibitory properties of the colony's contact network.
