Spiking Neural Networks for Visual Place Recognition via Weighted Neuronal Assignments

no code implementations14 Sep 2021 Somayeh Hussaini, Michael Milford, Tobias Fischer

This research introduces the first high performance SNN for the Visual Place Recognition (VPR) task: given a query image, the SNN has to find the closest match out of a list of reference images.

Bio-inspired robot perception coupled with robot-modeled human perception

no code implementations31 Aug 2021 Tobias Fischer

My overarching research goal is to provide robots with perceptional abilities that allow interactions with humans in a human-like manner.

Probabilistic Appearance-Invariant Topometric Localization with New Place Awareness

1 code implementation16 Jul 2021 Ming Xu, Tobias Fischer, Niko Sünderhauf, Michael Milford

Probabilistic state-estimation approaches offer a principled foundation for designing localization systems, because they naturally integrate sequences of imperfect motion and exteroceptive sensor data.

Intelligent Reference Curation for Visual Place Recognition via Bayesian Selective Fusion

no code implementations19 Oct 2020 Timothy L. Molloy, Tobias Fischer, Michael Milford, Girish N. Nair

A key challenge in visual place recognition (VPR) is recognizing places despite drastic visual appearance changes due to factors such as time of day, season, weather or lighting conditions.

Constraining the onset density of the hadron-quark phase transition with gravitational-wave observations

no code implementations6 Jun 2020 Sebastian Blacker, Niels-Uwe F. Bastian, Andreas Bauswein, David B. Blaschke, Tobias Fischer, Micaela Oertel, Theodoros Soultanis, Stefan Typel

The softening of the EoS by the PT at higher densities, i. e. after merging, leads to a characteristic increase of the dominant postmerger GW frequency f_peak relative to the tidal deformability Lambda inferred during the premerger inspiral phase.

Improved axion emissivity from a supernova via nucleon-nucleon bremsstrahlung

no code implementations27 Jun 2019 Pierluca Carenza, Tobias Fischer, Maurizio Giannotti, Gang Guo, Gabriel Martinez-Pinedo, Alessandro Mirizzi

We find that the axion emissivity is reduced by over an order of magnitude with respect to the basic OPE calculation, after all these effects are accounted for.
