A theory of data variability in Neural Network Bayesian inference

no code implementations31 Jul 2023 Javed Lindner, David Dahmen, Michael Krämer, Moritz Helias

Using our formalism on a synthetic task and on MNIST we obtain a homogeneous kernel matrix approximation for the learning curve as well as corrections due to data variability which allow the estimation of the generalization properties and exact results for the bounds of the learning curves in the case of infinitely many training data points.

Unified field theoretical approach to deep and recurrent neuronal networks

no code implementations10 Dec 2021 Kai Segadlo, Bastian Epping, Alexander van Meegen, David Dahmen, Michael Krämer, Moritz Helias

Bayesian inference on Gaussian processes has proven to be a viable approach for studying recurrent and deep networks in the limit of infinite layer width, $n\to\infty$.

Constraining dark matter annihilation with cosmic ray antiprotons using neural networks

2 code implementations26 Jul 2021 Felix Kahlhoefer, Michael Korsmeier, Michael Krämer, Silvia Manconi, Kathrin Nippel

The interpretation of data from indirect detection experiments searching for dark matter annihilations requires computationally expensive simulations of cosmic-ray propagation.

Autoencoders for unsupervised anomaly detection in high energy physics

NNLL-fast: predictions for coloured supersymmetric particle production at the LHC with threshold and Coulomb resummation

3 code implementations26 Jul 2016 Wim Beenakker, Christoph Borschensky, Michael Krämer, Anna Kulesza, Eric Laenen

We present state-of-the art predictions for the production of supersymmetric squarks and gluinos at the Large Hadron Collider (LHC), including soft-gluon resummation up to next-to-next-to-leading logarithmic (NNLL) accuracy, the resummation of Coulomb corrections and the contribution from bound states.

We present state-of-the-art cross section predictions for the production of supersymmetric squarks and gluinos at the upcoming LHC run with a centre-of-mass energy of $\sqrt{s} = 13$ and $14$ TeV, and at potential future $pp$ colliders operating at $\sqrt{s} = 33$ and $100$ TeV.
