We performed a systematic review of the evidence regarding effects of service reconfigurations that increase the time/distance for some patients to reach an urgent and emergency care (UEC) facility. How do you operate the motorcycles throttle? Particularly in LDA models, the generation of documents within a corpus follows the following process: A mixture of k topics, $\theta$, is sampled from a Dirichlet prior, which is parameterized by $\alpha$; A topic $z_n$ is sampled from the multinomial distribution, $p(\theta \mid \alpha )$ that is the document topic distribution which models $p(z_{n}=i\mid \theta )$ ; Fixed the number of topics $k=1 \ldots ,K$, the distribution of words for k topics is denoted by $\phi$ ,which is also a multinomial distribution whose hyper-parameter $\beta$ follows the Dirichlet distribution; Given the topic $z_n$, a word, $w_n$, is then sampled via the multinomial distribution $p(w \mid z_{n};\beta )$. Not dealing with these issues will cause immediate consequences. In the topic related to distance learning concerns, the importance of words such as school and work remained stable, while the word home decreased in importance as time passed until it vanished.
