[Retracted] Big Data Model of Higher Education Online Teaching Based on Intelligent Algorithm

Table 4

The actual training results and the frequency of interviews.

	Trainer’s time	Personal-emotional problems	Learning efficiency	Other force majeure
Online learning algorithm of perceptron	21	45	13	21
Passive-active algorithm in online learning	26	46	23	5
Online sparse solution learning algorithm	18	43	24	15

Various factors account for the frequency of the algorithm (%).
