Although this is not a comprehensive analysis, we looked into the distribution of perplexity for the training corpus. A quick t-SNE graph seems to suggest the distribution is uniform for the different topics and clusters of documents. The interactive plot (**perplexity_colored_embeddings.html**) is available in the **images** folder.

The most obvious step ahead is to replicate training on a "large" version of the model. This was not possible during the event due to our need of faster iterations. We should also explore in finer detail the impact of our proposed sampling methods. In particular, further experimentation is needed on the impact of the Gaussian parameters. Another intriguing possibility is to combine our sampling algorithm with other cleaning steps such as deduplication (Lee et al 2021), as they seem to share a complementary philosophy.

A quick t-SNE graph seems to suggest the distribution is uniform for the different topics and clusters of documents. The interactive plot (**perplexity_colored_embeddings.html**) is available in the **images** folder. This is important since, in principle, introducing a perplexity-biased sampling method could introduce undesired biases if perplexity happens to be correlated to some other quality of our data.

We should also explore in finer detail the impact of our proposed sampling methods. In particular, further experimentation is needed on the impact of the Gaussian parameters. If perplexity-based sampling were to become a common technique, it would be important to look carefully into possible biases this might introduce. Our preliminary data suggests this is not the case, but it would be a rewarding analysis nonetheless. Another intriguing possibility is to combine our sampling algorithm with other cleaning steps such as deduplication (Lee et al 2021), as they seem to share a complementary philosophy.
