Кл.слова (ненормированные):
machine learning methods -- modeling of machine learning method -- network equipment failure forecasts -- LAN
Аннотация: The article discusses three methods for predicting network equipment failures and the impact of the data array of input controllers. The purpose of the article is to reveal the relevance of the approach proposed by the authors to the use of large-amount of data in the chosen method of machine learning and to make a comparative analysis of the final values with the works of other world researchers. In the first section, the authors analyze the work of scientists from the Beijing University of Post and Telecommunications, noting the strengths and weaknesses of their method. In Section 2, the authors analyze the Holt-Winters method for developing algorithms for analyzing network traffic, which was applied by researchers from the Tomsk State University of Control Systems and Radio Electronics. In section 3, the authors applied the method of random trees in the modeling of machine learning methods of Rapid Miner Studio. The authors have carried out work with a large amount of data, and a comparative analysis of the results of modeling the method. The importance of using large amounts of information to train a model of network equipment failure forecasts is proved. In the final section, the authors highlight the need to improve forecasting models for its further implementation in the working environment. Also, the authors emphasize that the two articles considered by international researchers are a special case, as well as their chosen method for predicting failures in the LAN system.

piezo resistance -- negative magnetoresistance -- uniaxial pressure -- is energetic -- multivalley model -- valley crossing
Аннотация: The article presents experimental results obtained by studying the magnetoresistance of n-type silicon with an electron concentration of. nе=3,1-1013см-3 in the temperature range of 77.4-300K.There is a negative longitudinal magnetoresistance due to the redistribution of electrons between thevalleys. Experimental results are compared with existing theories and a good agreement is obtained bothquantitatively and qualitatively. At H=350 kE, the energy gap between the lowest Landau subzones is 7 MeV.These experimental results obtained in n-type silicon clearly demonstrate the reliability of the mechanismof negative magnetoresistance caused, indeed, by the pumping of current carriers between the valleys of theconduction band, shifting along the energy scale in a quantizing magnetic field at different speeds. The isenergetic surface of the bottom of the silicon conduction band consists of six ellipsoids located on the mainaxes of the cube, which causes anisotropy of the effective mass and relaxation time. The latter determines thefeatures of galvanomagnetic effects. Especially magnetoresistance is the most sensitive to the anisotropy ofthe is energetic surface. The influence of the latter on magnetoresistance is most clearly revealed in the regionof strong magnetic fields, where magnetoresistance is saturated.
