RETRACTED: Machine learning algorithm to analyse tipping behaviour based on decision tree model

Abstract

Nowadays, with the improvement in people’s quality of life, more and more people choose to travel abroad in leisure time. Therefore, the great difference in lifestyles could cause culture shock, which make tourists’ trip a relative awful experience, especially in the popular resorts of some countries such as Europe and America, where tips are given whenever there is a service being provided, and this behaviour confused lots of tourists from Asia, Africa or even European countries. Based on decision tree, this study aimed to share troubles of those tourists with needs by taking the New York City Taxi and Limousine Commission’s database as research’s target, thereby analysing factors that may cause variation in tipping rates. Finally, it is found that distance and duration contributed most to trip fare. Also, besides accurately predicting the tip amount, how each factor contributes to the trip needs to be known; thus, linear regression is used to check the validity of the result, and a 14.1% rate of all distance as a fee is achieved. This study provides a model – which can also be used in many different places – that tremendously improve people’s quality of life, and the main idea is relative to the fuzzy system in solving social problems.

A Perspective on the Current Situation of Children’s Education and Teachers’ Moral Cultivation Combined with Decision Tree Algorithm

“…After analyzing the dataset, the missing values and outliers are correct data reflecting the actual situation and are not processed. After this, each data point is statutory to [1,5].…”

“…Suppose the knowledge obtained by machine learning is applied to the information system of colleges and universities. In that case, the original system will become smarter and help us make better decisions or find more problems so as to improve the quality of education [4][5][6]. To this end, the classic algorithm of machine learning -the decision tree algorithm is applied to the current children's education platform to discover the potential information and rules of the data, to find the key factors affecting the quality of teaching and learning, so as to improve the children's education and teaching management level and teacher ethics.…”
