Hi there,

I think there might be a mistake in the documentation. The Understanding Scaled F-Score section says

The F-Score of these two values is defined as:

$$ \mathcal{F}_\beta(\mbox{prec}, \mbox{freq}) = (1 + \beta^2) \frac{\mbox{prec} \cdot \mbox{freq}}{\beta^2 \cdot \mbox{prec} + \mbox{freq}}. $$

$\beta \in \mathcal{R}^+$ is a scaling factor where frequency is favored if $\beta

Hello,

I am getting the following error message "error: package directory 'rake_nltk' does not exist" when installing rake-nltk with:
git clone https://github.com/csurfer/rake-nltk.git
python rake-nltk/setup.py install :

I also tried the option pip install rake-nltk but the installation also fails:

When using artm.SmoothSparseThetaRegularizer(tau=tau_val) with tau_val<0 we get some \Theta matrix columns filled totally with zeros. From perplexity score, the optimization converges. The quantity of documents with all zeros in their \Theta columns grows as $tau_val->-\infty$.
How it's possible that optimization constraint on theta columns violates?

Hi,
I used to have a previous version of LDAvis (2014) installed with devtools.
In the version I had of LDAvis I would call createJSON as:
json <- createJSON(K, phi, term.frequency, vocab, topic.proportions)

Today I updated my R packages and have a newer vesion of LDAvis (from CRAN) which uses createJSON as:
json <- createJSON(phi, theta, doc.length, vocab, term.frequency)

I'm using MALLET for t
