Abstract

The invention discloses a student evaluation method and system based on AI identification data, and relates to the field of intelligent education. A lightweight network model suitable for student evaluation, the model taking AI identification data as an input and taking an evaluation result as an output; a training data generation algorithm is provided, multi-dimensional AI identification data and labels are uniformly processed into training data suitable for a network model through the algorithm, and the problems that the dimensions between any AI identification data and various labels are not uniform, and native data cannot meet multi-dimensional and cross-time prediction model training can be solved; a simulation data generation algorithm and a simulation label generation algorithm are provided, the algorithms are used and matched with a training data generation algorithm, and the training data generation algorithm generates simulation training data. The network model is pre-trained by using the generated simulation training data, thereby solving the problem of insufficient label quantity in application scenarios such as student evaluation.

Description

technical field [0001] The invention relates to the field of intelligent education, in particular to a student evaluation method and system based on AI recognition data. Background technique [0002] With the vigorous development and maturity of artificial intelligence technology, it is widely used in various scenarios. In classroom scenarios, artificial intelligence technology is often used to identify students' emotions, postures, sights, etc. At the current stage, artificial intelligence technology in the classroom environment is usually recognized in a single technical dimension, that is, each plays its own recognition function, and it is also recognized in a single space-time dimension, that is, it only recognizes a single student at the current stage. This kind of single-technology dimension and single-space-time dimension recognition cannot fully utilize the benefits brought by this kind of technology to the field of intelligent education, and there are problems such...
