WebBenchmarks — bitermplus documentation Benchmarks Edit on GitHub Benchmarks In this section, the results of a series of benchmarks done on SearchSnippets dataset are presented. Sixteen models were trained with different iterations number (from 10 to 2000) and default model parameters. Topics number was set to 8. WebHowever, when i use the marked sample to train the model. i got the unexpeted result. Firstly, the marked samples contain 5 types, but trained model get a huge perlexity when the the number of topic is 5. Secondly, when i test the topic parameter from 1 to 20, the perplexity was reduced following the increase of topic number. my code is following:
