Our Chief Weapon in Programming
/ Van Eerd, Tony (speaker) (Christie Digital)
If I had time to convey just one* piece of programming advice, what would it be? Over the years I've often wondered "If I could only follow one bit of programming advice, what would it be", and have asked many people the same. I think I have narrowed down the one* rule I follow and have actually always followed, and which I find has helped me write correct, fast, understandable, maintainable code. [...]

Learning New Physics from a machine
/ Wulzer, Andrea (speaker) (CERN)
We propose using neural networks to detect data departures from a given reference model, with no prior bias on the nature of the new physics responsible for the discrepancy. The model-independent nature of our approach, and its ability to deal with rare signals such as those expected at the LHC, is quantitatively assessed in toy examples..

Guiding New Physics Searches with Unsupervised Learning
/ De Simone, Andrea (speaker) (SISSA)
I will describe an approach to search for new phenomena in data, by detecting discrepancies between two datasets. These could be, for example, a simulated standard-model background, and an observed dataset containing a potential hidden signal of New Physics.
I will propose a new statistical test, built upon a test statistic which measures deviations between two samples, using a Nearest Neighbors approach to estimate the local ratio of the density of points.
The test is model-independent and non-parametric, requiring no knowledge of the shape of the underlying distributions, and it does not bin the data, thus retaining full information from the multidimensional feature space.
As a by-product, the technique is also a useful tool to identify regions of interest for further study.
As a proof-of-concept, I will show the power of the method when applied to synthetic Gaussian data, and to a simulated dark matter signal at the LHC..

EARLY-CAREER RESEARCHERS IN MEDICAL APPLICATIONS @ CERN – SHORT TALKS
/ Stringhini, Gianluca (speaker) (Universita & INFN, Milano-Bicocca (IT)) ; Kozlowska, Wioletta Sandra (speaker) (CERN) ; Nowak, Marie (speaker) (UNIL - Universite de Lausanne (CH)) ; Gowtham , ADITHYA RAGHUPATHI (speaker) ; HUSSEIN, SHAUKATALI ZAHIR (speaker) ; MOHAMEDALI , Maryam (speaker)
Discover how technological advances for high-energy physics have become essential tools for modern medicine.
This series of short talks is given by Early-Career Researchers working on projects related to diverse medical applications that arise from technology developed at CERN and in high-energy physics.
The short talks from CERN researchers will focus on PET, Simulations and Dosimetry in Surgery
Team 2.7 from the recent Medtech:Hack will also present their winning project which aims to find solutions for people in rural areas to get better access to vital healthcare.
See more about the Medtech: Hack here.
Attendance is open to all without registration. If you require a CERN access card please contact us.
Coffee will be served at 15.30
