interactive_embedding_exploration: Interactive exploration of embeddings
In projector: Project Dense Vectors Representation of Texts on a 2D Plan

Description Usage Arguments Details Examples

Shiny application to interactively play with embeddings. User provides a pivot word and the n most similar word are projected on a scatter plot.

1 2	interactive_embedding_exploration(annoy_model, default_number_neighbors = 100, default_number_rounds = 500, default_perplexity = 30)

`annoy_model`	RcppAnnoy model generated with get_annoy_model
`default_number_neighbors`	set the number of neighbors slider to this value
`default_number_rounds`	set the number of `T-SNE` rounds slider to this value
`default_perplexity`	set the `T-SNE` perplexity slider to this value

For large list of texts, the auto-complete can be slow.

Increasing the number of neighbors can make things very slow, in particular with T-SNE approach. 500 neighbors is usually a good value to have an understanding of the neighborhood of a vector.

Colors in the scatter plot represents clusters found by dbscan.
