Physically-Informed Fuzzy Clustering of Vertical Sounding Ionograms
Oleg I. Berngardt, Sergey N. Ponomarchuk
This paper presents a physically-informed fuzzy clustering of vertical sounding ionograms for automatically separating the ionogram into tracks suitable for further interpretation…
Self-learning signal classifier for decameter coherent scatter radars
Oleg Berngardt, Ivan Lavygin
The paper presents a method for automatic constructing a classifier for processed data obtained by decameter coherent scatter radars. Method is based only on the radar data obtaine…
Minimum number of neurons in fully connected layers of a given neural network (the first approximation)
Oleg I. Berngardt
This paper presents an algorithm for searching for the minimum number of neurons in fully connected layers of an arbitrary network solving given problem, which does not require mul…
Superclustering by finding statistically significant separable groups of optimal gaussian clusters
Oleg I. Berngardt
The paper presents the algorithm for clustering a dataset by grouping the optimal, from the point of view of the BIC criterion, number of Gaussian clusters into the optimal, from t…
Interferometric calibration and the first elevation observations at EKB ISTP SB RAS radar at 10-12 MHz
Oleg I. Berngardt, Roman R. Fedorov, Pavlo Ponomarenko +1
The method for calibrating elevation measurements at EKB ISTP SB RAS radar obtained for the period 20/09/2019 - 18/11/2019 is presented. The calibration method is a modernization o…
Comparison of AATR and WTEC indices in the studies of the level of ionospheric disturbance
Oleg I. Berngardt, Sergey V. Voeykov, Natalia P. Perevalova
A comparative statistical analysis of AATR and WTEC indices was conducted based on data from the ISTP SB RAS GNSS receivers network. It is shown that at high levels of ionospheric…
