An LSTM-Based Dynamic Customer Model for Fashion Recommendation
Sebastian Heinz, Christian Bracher, Roland Vollgraf
Online fashion sales present a challenging use case for personalized recommendation: Stores offer a huge variety of items in multiple sizes. Small stocks, high return rates, season…
Fashion DNA: Merging Content and Sales Data for Recommendation and Article Mapping
Christian Bracher, Sebastian Heinz, Roland Vollgraf
We present a method to determine Fashion DNA, coordinate vectors locating fashion items in an abstract space. Our approach is based on a deep neural network architecture that inges…
Propagation of charged particle waves in a uniform magnetic field
Christian Bracher, Arnulfo Gonzalez
This paper considers the probability density and current distributions generated by a point-like, isotropic source of monoenergetic charges embedded into a uniform magnetic field e…
New Mathematical Tools for Quantum Technology
Christian Bracher, Manfred Kleber, Tobias Kramer
Progress in manufacturing technology has allowed us to probe the behavior of devices on a smaller and faster scale than ever before. With increasing miniaturization, quantum effect…
The photoelectric effect in external fields
Christian Bracher, John B. Delos, Vassiliki Kanellopoulos +2
Atoms and negative ions interacting with laser photons yield a coherent source of photoelectrons. Applying external fields to photoelectrons gives rise to interesting and valuable…
Electron dynamics in parallel electric and magnetic fields
Christian Bracher, Tobias Kramer, John B. Delos
We examine the spatial distribution of electrons generated by a fixed energy point source in uniform, parallel electric and magnetic fields. This problem is simple enough to permit…
