These particles are nearly a billion times as energetic as the particles in the Large Hadron Collider, and their origin is a mystery. The physics parameters represent a smoothly varying learning task, and the resulting parameterized classifier can smoothly interpolate between them and replace … Rev.

Evolving neural networks through augmenting topologies. The LEP Collaboration. A C. Peterson, Track finding with neural networks. Lett. New articles related to this author's research. The challenge is that UHECRs are very rare with about 1 particle per square kilometer over 100 years. Extensive air showers generated by cosmic rays produce muons and high-energy photons, which can be detected by the CMOS sensors of smartphone cameras. Add co-authors Co-authors. Sci. A B. van Merrinboer, D. Bahdanau, V. Dumoulin, D. Serdyuk, D. Warde-Farley, J. Chorowski, Y. Bengio. Phys. Most collisions, however, do not produce top quarks and making precise measurements requires culling these collisions into a sample that is rich in collisions producing top quarks (signal) and spare in collisions producing other particles (background). Support vector regression as a signal discriminator in high energy physics. In addition, they may outperform isolated networks by generalizing from the full parameter-dependent dataset.In the following, we describe the network structure needed to apply a single parameterized network to a set of smoothly related problems and demonstrate the application for theoretical model parameters (such as new particle masses) in a set of examples of increasing complexity.A typical network takes as input a vector of features, Training data for the parameterized network has the form As a demonstration for a simple toy problem, we construct a parameterized network which has a single input feature A natural physical case is the application to the search for new particle of unknown mass.

His research uses the LHC to investigate the basic building blocks of the Universe around us, hoping to find new kinds of particles or interactions and reveal a deeper and simpler layer underlying our reality.In 2014, Whiteson set out on a mission to conceive the largest particle experiment ever constructed. We investigate a new structure for machine learning classifiers built with neural networks and applied to problems in high-energy physics by expanding the inputs to include not only measured features but also physics parameters. [A single parameterized network can replace a set of individual networks trained for specific cases, as well as smoothly interpolate to cases where it has not been trained. This "Cited by" count includes citations to the following articles in Scholar.

While these example use a single parameter Parameterized networks can also provide optimized performance as a function of nuisance parameters that describe systematic uncertainties, where typical networks are optimal only for a single specific value used during training. The low-level features are the four-vectors of the reconstructed events, namely:the missing transverse momentum magnitude and angleDistributions of high-level event features for the decay of The parameterized deep neural network models were trained on GPUs using the Blocks framework [The high dimensionality of this problem makes it difficult to visually explore the dependence of the neural network output on the parameter Comparison of the signal-to-background discrimination for four classes of networks for a testing sample with Comparison of the performance in the signal-background discrimination for the parameterized network, which learns the entire problem as a function of mass, and a single network trained only at In previous work, we have shown that deep networks such as these do not require the addition of high-level features [We have presented a novel structure for neural networks that allows for a simplified and more powerful solution to a common use case in high-energy physics and demonstrated improved performance in a set of examples with increasing dimensionality for the input feature space. In high energy physics, AI methods can aid precision measurements that elucidate the underlying structure of matter, such as measurements of the mass of the top quark.
