2nd Round Table on Machine and Deep Learning at DESY

Friday 29 Nov 2019, 10:00 → 16:00 Europe/Berlin

Seminar Room (Bldg. 28C Flash Hall)

The number of activities on machine and deep learning within the heterogenous research landscape on DESY campus is continuing to rise. To enable and strengthen inter-department comm-unication and collaboration between the ML/DL experts on campus we invite you to the 2nd Round Table on Machine and Deep Learning at DESY.

If you are already working with or plan to work machine or deep learning, you are welcome.

Please register for this event (primarily to ensure we have enough coffee).

10:00 → 10:10 Welcome

10:10 → 11:30 ML/DL @ DESY-campus 1

Presentations from DESY campus colleagues on ML/DL

10:10 Convolutional Neural Networks for electron microscopy tomography

12:05 Neural networks for small angle scattering data analysis.

We propose a novel method of SAXS data analysis based on application of interconnected neural networks (perceptrons). For given experimental data from proteins, RNA or DNA our stack of networks evaluates Rg, Dmax, MW, p(r) and a noise-free scattering curve. This completely automatic approach has proved to be robust against experimental errors, applicable to data from particles of various nature, size, and shape. The method was implemented as a publicly available web service with a graphical interface, providing the possibility to inspect and download the results (https://dara.embl-hamburg.de/gnnom.php).

Speaker: Dr Dmitry Molodenskiy (EMBL)

12:25 Anomaly Detection for SRF Cavities

The European XFEL uses superconducting radiofrequency cavities for the electron acceleration. In total 808 cavities are operated in pulsed mode with a 10 Hz repetition rate, which amounts to ~700 Million RF-pulses in 24 hours. This talk explores the possibility of monitoring anomalous behavior of individual cavities and determining levels of anomaly for each pulse.

Speaker: Ayla Nawaz (DESY/MSK)

12:45 Classification for Single Particle Imaging experiments

Speaker: Dr Alexandr Ignatenko (DESY)

13:05 → 14:00 Lunchbreak

coffee, refreshments and open discussion

14:00 → 15:00 Snap ML - Accelerated Machine Learning for Business

Haris Pozidis, PhD
Manager Cloud Storage & Analytics, Principal RSM, Master Inventor, IBM Research

Snap Machine Learning (Snap ML) is a new software library for training machine learning models that is characterized by very high performance, scalability to TB-scale datasets and high resource efficiency. It continuously evolves and currently supports generalized linear models, decision trees, random forests and gradient boosting machines. Snap ML has been built to address the needs of business applications, which often have to deal with data that is big in size, react fast to changing environments, and use resources efficiently to drive down cost. In addition, with the most recent addition of a new gradient boosting model, Snap ML offers high generalization accuracy, which drives higher profits in AI-infused business applications. In this talk I will present the principles of the Snap ML library, explain how it achieves high speed and scalability, and present several cases of business workloads that demonstrate the benefits reaped by Snap ML.
