Construction of Multimedia Assisted Legal Classroom Teaching Model Based on Data Mining Algorithm
| Type | Definition | Characteristic | Specific representative method |
| Unsupervised discretization | A method that does not use class information in the discretization process | The method is simple and easy to operate, but it needs to specify the number of intervals artificially | Equal width box method | Equal frequency box method | String analysis method |
| Supervised discretization | A method that uses class information in the discretization process | There is no need to specify the number of intervals artificially, but the operation is complex | IR method | Entropy based discretization method | Discretization method based on chi square |
