Word2Vec: Number of Dimensions
I am using Word2Vec with a dataset of roughly 11,000,000 tokens looking to do both word similarity (as part of synonym extraction for a downstream task) but I don't have a good sense of how many dimensions I should use with Word2Vec. Does anyone have a good heuristic for the range of dimensions to consider based on the number of tokens/sentences? Cylonmath Typical interval is between 100-300. I would say you need at least 50D to achieve lowest accuracy. If you pick lesser number of dimensions, you will start to lose properties of high dimensional spaces. If training time is not a big deal for
