چکیده
Establishing a reasonable and efficient compulsory education balance index system is very important to boost the all-around of development, then realize course recommendation for students with different attributes. Based on this, research aimed at problems in college English evaluation, establish MOOC evaluation based improved neural network algorithm. The first constructed data elements, established genetic algorithm (BP Neural Network Optimization Algorithm Genetic Algorithm, GA-BP), finally analyzed effect assembled model. These results show that fitness GA-BP model reaches set expectation when evolutionary algebra 10 times, its 0.6. corresponding threshold weight are obtained, substituted into After repeated iterative training, reached an error 10-3 it was trained 12 expected accuracy achieved. R value each hovered around 0.97, fitting degree high, which showed proposed study had better degree. difference between output mainly distributed [-0.08083, 0.06481] interval. To sum up, has excellent evaluation. This faster learning rate higher prediction more stable performance.

Hotel Recommendation Based on Hybrid Model
This project develops a hybrid model that combines content-based with collaborative filtering (CF) for hotel recommendation. This model considers both hotel popularity in input destination and users preference. It produces the prediction with 53.6% accuracy on test data-4% improvement on purely content-based model. Addtionally, three issues are well-resolved when implementing CF: sparsity in ut...

The accuracy of the traditional online recommendation system, much depends on the collaborative filtering recommendation algorithm, however, recommend system aims to attract the interest of consumers and turn visitors into buyers, rather than accurately predict their score. Online recommendation system is the service version of social filtering process. Most previous studies emphasize the accur...
