object detection, or a custom coded model with MLflow, then imported as a Dataiku model, all it takes is a few clicks to create a containerized inference API service on top of the trained model.
在讲LDA模型之前,再循序渐进理解基础模型:Unigram model、mixture of unigrams model,以及跟LDA最为接近的pLSA模型。为了方便描述,首先定义一些变量: ww 表示词,VV 表示所有单词的个数(固定值)。 zz 表示主题,kk 是主题的个数(预先给定,固定值)。 D=(W1,...,WM)D=(W1,...,WM) 表示语料库,其中的M是语...

topic model 是一种应用十分广泛的产生式模型(generative model),在IR, NLP,ML都有广泛的应用,本文将对目前已有的topic model进行分类总结,然后选择几个代表性的topic model进行较为详细的介绍,从而理解topic model 的思想,以及怎么应用。 topic model最经典的模型之一是LDA(latent dirichlet allocation) ,其它的topic...
在讲LDA模型之前，再循序渐进理解基础模型：Unigram model、mixture of unigrams model，以及跟LDA最为接近的pLSA模型。为了方便描述，首先定义一些变量：反过来，既然文档已经产生，那么如何根据已经产生好的文档反推其主题呢？这个利用看到的文档推断其隐藏的主题（分布）的过程（其实也就是产生文档的逆过程）...
