This could suggest, as others have claimed, that asking questions about female sexual pleasure is disruptive (McClelland and Fine 2008), bringing a frequently hidden topic into the discussion.
Here, W njk denotes the weight between visible unit n that takes on value k and hidden topic j; b j is the bias of hidden topic j, and a nk is the bias of visible unit n that takes on value k. σ(x)=1/(1+ exp(−x)) is the logistic function.
David Blei, professor of computer science and statistics, led the groundbreaking research that resulted in the development of the Latent Dirichlet Allocation (LDA) model, a topic model capable of exploiting hidden topics and semantic themes among countless lines in billions of documents via language processing.
"The twist on it that we're trying to transpose from the general domain is to treat occurrences of a target word as documents and to treat senses as hidden topics that we're trying to infer," Rumshisky says.
To combat this challenge, their approach focuses on detecting hidden topics for the tweets and then suggests the use of those general topics as hashtags using a latent dirichlet allocation (LDA) model to facilitate better search.
Inference in LDA involves the estimation of hidden topics h and x given the words v for each document, i.e. p(h,x|V,α,W).
The major challenges in short text understanding are that short texts usually do not have the correct syntax that traditional POS-taggers or parsing methods can utilize and that they lack sufficient content to support statistical approaches to detect hidden topics.
However, projects under implementation may hide topic preferences that are not translated into projects or topics that were generated and funded through joint actor participation.
In his blog Arrington says CNN "went to great lengths to hide the topic of the interview".
They have only five minutes total to converse on any topic of their choice both with a human hidden behind one-half of the screen and a machine hidden behind the other.
To start, let's break the taboos that have kept this topic hidden.
