... as a latent topic analysis method, and assign topics to Events in a document. To examine our proposed method s performance on extracting latent topics from a doc- ument, we compare the accuracy ... distribution based on the idea that each topic emerges in a document based on a certain probability. Each topic is expressed as a multinomial distribu...

... denote conditional dependencies among the variables. In our dialog model, a dia- log transcript x consists of an alternating sequence of system actions and observed user actions: x = (S 0 , ˜ A 0 , ... the val- ues of S t , U t , A t and ˜ A t are all assumed to belong to finite sets, and so all the conditional distributions in our model are multinomials. Hence θ is a vec-...

By contrast, in hypoxic chromatin only very little PCNA was detected. However PCNA increased strongly as soon as 5 min after reoxygenation and continu...
