Machine learning challenges in theoretical HEP
In these proceedings we perform a brief review of machine learning (ML)
applications in theoretical High Energy Physics (HEP-TH). We start the
discussion by defining and then classifying machine learning tasks in
theoretical HEP. We then discuss some of the most popular and recent published
approaches with focus on a relevant case study topic: the determination of
parton distribution functions (PDFs) and related tools. Finally, we provide an
outlook about future applications and developments due to the synergy between
ML and HEP-TH.Comment: 7 pages, 3 figures, in proceedings of the 18th International Workshop

Online Clustering of Bandits
We introduce a novel algorithmic approach to content recommendation based on
adaptive clustering of exploration-exploitation ("bandit") strategies. We
provide a sharp regret analysis of this algorithm in a standard stochastic
noise setting, demonstrate its scalability properties, and prove its
effectiveness on a number of artificial and real-world datasets. Our
experiments show a significant increase in prediction performance over
state-of-the-art methods for bandit problems.Comment: In E. Xing and T. Jebara (Eds.), Proceedings of 31st International

Mapping Subsets of Scholarly Information
We illustrate the use of machine learning techniques to analyze, structure,
maintain, and evolve a large online corpus of academic literature. An emerging
field of research can be identified as part of an existing corpus, permitting
the implementation of a more coherent community structure for its
practitioners.Comment: 10 pages, 4 figures, presented at Arthur M. Sackler Colloquium on

Graph Signal Processing: Overview, Challenges and Applications
Research in Graph Signal Processing (GSP) aims to develop tools for
processing data defined on irregular graph domains. In this paper we first
provide an overview of core ideas in GSP and their connection to conventional
digital signal processing. We then summarize recent developments in developing
basic GSP tools, including methods for sampling, filtering or graph learning.
Next, we review progress in several application areas using GSP, including
processing and analysis of sensor network data, biological data, and
applications to image processing and machine learning. We finish by providing a
brief historical perspective to highlight how concepts recently developed in
GSP build on top of prior research in other areas.Comment: To appear, Proceedings of the IEE
A Compilation Target for Probabilistic Programming Languages
Forward inference techniques such as sequential Monte Carlo and particle
Markov chain Monte Carlo for probabilistic programming can be implemented in
any programming language by creative use of standardized operating system
functionality including processes, forking, mutexes, and shared memory.
Exploiting this we have defined, developed, and tested a probabilistic
programming language intermediate representation language we call probabilistic
C, which itself can be compiled to machine code by standard compilers and
linked to operating system libraries yielding an efficient, scalable, portable
probabilistic programming compilation target. This opens up a new hardware and
systems research path for optimizing probabilistic programming systems.Comment: In Proceedings of the 31st International Conference on Machine
