Distance metric (

...

--metric)

The metric to use when computing distances in high-dimensional space. 

Number of iterations (

...

--n_epochs)

UMAP uses an iterative algorithm to optimize the low-dimensional representation. The value 0 corresponds to the default, which chooses the number of iterations based on the size of the input data. More iterations will result in a more accurate embedding, but will take longer to run.

Random generator seed (

...

--random_state)

Several parts of UMAP utilize a random number generator to provide an initial value. The value 0 corresponds to the default of the underlying algorithm.
