RETRACTED: Research on the Predictive Analysis of Park Landscape Design and Cost Based on RNN Model

Table 1

Comparison of project cost prediction methods.

Prediction methods	Advantages	Disadvantages	Accuracy
Fuzzy mathematics	Very good logical reasoning and intellectual presentation skills	Highly subjective; lack of automatic access to rules	Low
Grey theory	No requirement for sample size	Failure to consider the dynamic nature of project costs	Low
Regression analysis	Simple models	Uncertain factors are not considered	Low
Bayes prediction	Greater flexibility	Highly subjective	Low
Time-series prediction	No requirement for sample size	High requirements for data reliability	High
Support vector machines	Fast prediction	Difficulties in training large samples	High
Neural networks	High precision	Stronger data dependency	High
