Evaluating dimensionality reduction?

Thanks for the hints, Leland. I will try to implement my version of the metrics for large datasets or, at least, a methodology to do it with what is available....

Evaluating dimensionality reduction?

I got these visualizations of fashion mnist with t-SNE and LargeVis (trains+test=70000 using labels only for the colors). It looks like LargeVis looks better, but then when I evaluate both...

Evaluating dimensionality reduction?

Thank you for sharing, UMAP is doing great (visually). I definitely need to study the details of your implementation. Are you planning to submit a preprint soon? (just trying to...

Using LargeVis instead t-SNE?

Cool, more interesting work coming up. The same authors of LargeVis create [LINE](https://github.com/tangjianpku/LINE) for learning network embeddings. Cool and scalable algorithms in case you need them. Attached there is a...

Using LargeVis instead t-SNE?

I've doing tests of your recommendation HDBSCAN for the clustering and the results are promising when using the results of LargeVis. Here, I attached the output of the HDBSCAN clustering...

Using LargeVis instead t-SNE?

@legel yes, I used the raw pixel values to compute it. @lmcinnes It is true LargeVis is partially based on t-SNE and as you mention the most important feature is...
