The European Union funded the FLARECAST project, that ran from January 2015 until February 2018. had a research-to-operations (R2O) focus, and accordingly introduced several innovations into discipline of solar flare forecasting. were: first, treatment hundreds physical properties viewed as promising predictors on equal footing, extending multiple previous works; second, use fourteen (14) different machine learning techniques, also to optimize immense Big Data parameter space created by...
A tabu search algorithm is proposed for the maximum score estimator computation, where focus on large sample size and number of estimated parameters. This a deterministic rather than stochastic one. The much faster Simulated Annealing, while providing solutions about same quality. software provided as Fortran console program C++ Graphical User Interface application. It demonstrated using an empirical study concerning labour force participation married women. Comparison with Mixed Integer...
A set of various short artificial disturbances from rifle firings, car engine operation, radio, shakings the apparatus, etc. , were generated deliberately near our ELF recording stations in order to identify their footprint on recordings atmospheric electromagnetic radiation Schumann resonance (SR) band (from about 2–50 Hz). Such simulate anthropogenic noises hunters, hikers, campers, etc., which may occur a remote-isolated station. We expect that work will assist fellow scientists...
We show that exact computation of the censored least absolute deviations (CLAD) estimator proposed by Powell (1984) may be achieved formulating as a linear Mixed Integer Programming (MIP) problem with disjunctive constraints. apply our approach to three previously studied datasets and find widely used approximate optimization algorithms can lead erroneous conclusions. Extensive simulations confirm MIP- based using available solvers is effective for typically encountered in econometric...
