May be with embedding like those of starspace I would check if a paragraph is close to the embedding of the full document for instance, but it s less interesting.\r\nFor annoy parameters you need to understand that basically each tree randomly split the space in n parts, and more trees you have more division of the space you get. between 10 and 50 seems good. At some point you are just making annoy slow without adding quality. For tsne, each iteration tries to find the best positions of points where some quality from the initial space are preserved. Several parameters deals with the number of tries before stabilizing, number of iterations is the main. Too high, you are just loosing time but quality won't be degraded."}}
