In the age of network information, science and technology advance by leaps and bounds, and people have put forward higher requirements for a large amount of data and information in their lives. Data mining can extract effective and valuable information that can guide people to make decisions from a large number of existing data by using data mining techniques and algorithms. This paper mainly studies the application of C4.5 algorithm in the performance analysis of ocean engineering major. This paper collects data based on online learning platform, and conducts data processing and correlation analysis of learning behavior data. In this paper, by analyzing the influence of each special on the final grade, the C4.5 algorithm was introduced to improve. Based on C4.5 algorithm, this paper constructs a performance analysis model, which can effectively analyze teachers' performance in each stage of course learning.
