Controls, Indicators and Equipment. These datasets are available from the corresponding author upon reasonable request. Learn. A distance-time graph shows how far an object has travelled in a given time. Apart from the general data-cleaning methods, tokenization and lemmatization could enable the model to achieve better performance.

Sentiment analysis of Arabic tweets regarding distance learning in Saudi Arabia during the COVID-19 pandemic. This way, if you have to abruptly stop, there's a better chance of avoiding a collision. 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 \(p(w \mid z_{n};\beta )\). Differ. 52); it fixed reopenings of schools and commercial activities in gradual terms, depending on the degree of epidemic risk in the different areas.
