Sequentially Executed Model Evaluation Framework

None None
Provides a message passing framework between generic input, model and output drivers, and specifies an API for developing such drivers. Also provides batch and real-time controllers which step the model and 1/0 through the time domain (or other discrete domain), and sample 1/0 drivers. This is a Framework library framework, and does not, itself, solve any problems or execute any modelling. The SeMe framework aids in development of models which operate on sequential information, such...

SPRNG Scalable Parallel Random Number Generator LIbrary

Ashok Srinivasan
This revision corrects some errors in SPRNG 1. Users of newer SPRNG versions can obtain the corrected files and build their version with it. This version also improves the scalability of some of the application-based tests in the SPRNG test suite. It also includes an interface to a parallel Mersenne Twister, so that if users install the Mersenne Twister, then they can test this generator with the SPRNG test suite and also use some SPRNG...

Multi-species impurity granule injection and mass deposition projections in NSTX-U discharges Authors

R Lunsford, A Bortolon, A Roquemore, D Mansfield, M Jaworski, R Kaita, R Maingi & A Nagy
By employing a neutral gas shielding (NGS) model to characterize impurity granule injection the pedestal atomic deposition for three different species of granule: lithium, boron, and carbon are determined. Utilizing the duration of ablation events recorded on experiments performed at DIII-D to calibrate the NGS model we are able to quantify the ablation rate and mass deposition location with respect to the plasma density profile. The species specific granule shielding constant is then used to...

100 TeV pp collisions, SM type, PYTHIA8 generator: tev100pp_minbias_a2_pythia8_l3

S. Chekanov
MinBias events used to mix with signal processes. 60k events per file. Pythia8 Minimum bias (ND+SD+DD) sample with ATLAS MB Tune A2-MSTW2008LO tune, i.e. events include non-diffractive, single diffractive and double diffractive events. Events are slimmed with pT>0.4 GeV cut. The file uses low-precision varint 1000 ("l3") for length units to make it comparable with some signal files. Due to reduced precision for decay length, this file is smaller than the standard file with 10^4...

Detection Framework Testbed and Toolkit

Douglas Dodge
The Detection Framework Testbed and Toolkit (DFTT) is a signal detection system that uses automatically generated subspace and correlation detectors. DFTT is intended to facilitate the development and testing of algorithms for operating suites of such detectors. The software is a generalization of the system described in Harris and Dodge (2011) and has been applied in contexts ranging from local borehole induced seismicity to large-scale teleseismic observations. The software includes interactive applications for creating detection...

Active Learning for NLP Systems

Andre Goncalves, Ana Sales, Hiranmayi Ranganathan, Braden Soper & Priyadip Ray
This software implements an active learning framework for Natural Language Processing (NLP) systems. It is intended to be applied on scenarios where limited amount of labeled data is available to train a machine learning-based NLP classification system, but a large set of unlabeled documents exist. This software will point, from the set of unlabeled documents, which ones we should label next so that the overall performance of the classifier is improved.
