We present several methods towards construction of precursors, which show great promise early predictions, solar flare events in this paper. A data pre-processing pipeline is built to extract useful from multiple sources, Geostationary Operational Environmental Satellites (GOES) and Solar Dynamics Observatory (SDO)/Helioseismic Magnetic Imager (HMI), prepare inputs for machine learning algorithms. Two classification models are presented: flares quiet times active regions strong versus weak...

Abstract We consider the flare prediction problem that distinguishes flare-imminent active regions produce an M- or X-class in succeeding 24 hr, from quiet do not any flares within ±24 hr. Using line-of-sight magnetograms and parameters of two data products covering Solar Cycles 23 24, we train evaluate deep learning algorithms—a convolutional neural network (CNN) a long short-term memory (LSTM)—and their stacking ensembles. The decisions CNN are explained using visual attribution methods....

Predicting the dynamics and functions of microbiomes constructed from bottom-up is a key challenge in exploiting them to our benefit. Current models based on ecological theory fail capture complex community behaviors due higher order interactions, do not scale well with increasing complexity considering multiple functions. We develop apply long short-term memory (LSTM) framework advance understanding assembly health-relevant metabolite production using synthetic human gut community. A...

Abstract Predicting the dynamics and functions of microbiomes constructed from bottom-up is a key challenge in exploiting them to our benefit. Current ordinary differential equation-based models fail capture complex behaviors that fall outside predetermined ecological theory do not scale well with increasing community complexity considering multiple functions. We develop apply long short-term memory (LSTM) framework advance understanding assembly health-relevant metabolite production using...

In this paper, we consider incorporating data associated with the sun’s north and south polar field strengths to improve solar flare prediction performance using machine learning models. When used supplement local from active regions on photospheric magnetic of sun, provides global information predictor. While such features have been previously proposed for predicting next cycle’s intensity, in paper propose them help classify individual flares. We conduct experiments HMI employing four...

Many applications produce multiway data of exceedingly high dimension. Modeling such multi-way is important in multichannel signal and video processing where sensors multi-indexed data, e.g. over spatial, frequency, temporal dimensions. We will address the challenges covariance representation review some progress statistical modeling past two decades, focusing on tensor-valued models their inference. illustrate through a space weather application: predicting evolution solar active regions time.
