-Fitting topic models at scale using classical algorithms on CPUs can be

-Poisson NMF and multinomial topic model likelihoods, and proposed a
-novel optimization strategy: fit a Poisson NMF via coordinate descent,
-then recover the corresponding topic model through a simple
-transformation. This method was implemented in their R package,
-[fastTopics](https://cran.r-project.org/package=fastTopics).

-Building on this theoretical insight, tinytopics adopts an alternative
-approach by directly solving a sum-to-one constrained neural Poisson
-NMF, optimized using stochastic gradient methods, implemented in
-PyTorch. Although this approach may not have the same theoretical
-guarantees, it does have a few potential practical benefits:
-
-- Scalable: Runs efficiently on both CPUs and GPUs and enables
-  large-scale topic modeling tasks.
-- Extensible: The model architecture is flexible and can be extended,
-  for example, by adding regularization or integrating with other data

-- Minimal: The core implementation is kept simple and readable,
