inference bug?
phi never be used in inference?
translate函数中limit过大会出问题
ldautil第41行应改为for (int i = 0; i < limit && iterator.hasNext() ; ++i)，否则limit超过iterator的大小的时候会报错
Inference新文档中有生单词问题
首先感谢hankcs博主的分享，在使用LDA4j的过程中，我重写了Corpus类里的load和loadDocument方法，从数据库中读写数据测试成功。
但是测试的过程中遇到了一个问题，就是先用训练集训练出来phi，然后拿来一个新文档使用这个phi推断其概率分布发现报数组越界的错误，我初步调试发现一旦新文档中包含训练集中没有的生单词，你写的Inference便无法使用，这个问题希望博主能进行一下异常处理。
有相关的api文档吗，如何获得新文档的主题分布？
有相关的api文档吗，请问如何获得新文档的主题分布？
int[] document = Corpus.loadDocument("data/mini/军事_510.txt", corpus.getVocabulary());
double[] tp = LdaGibbsSampler.inference(phi, document);
Map<String, Double> topic = LdaUtil.translate(tp, phi, corpus.getVocabulary(), 100);
LdaUtil.explain(topic);
憨批
LdaUtil
Map<Double, String> rankMap = new TreeMap<Double, String>(Collections.reverseOrder());
把double和string互换一下谢谢
