does thoes lines are equivalent?
显示 更早的评论
Does this line in Matlab
g = mdscale(dist, 2, 'criterion','metricstress');
is equivalent in python to those lines
mds=manifold.MDS(max_iter=200, eps=1e-4, n_init=1, dissimilarity="precomputed")
g=mds.fit_transform(dist)
I searched but didn't find mdscale in python and the scaling processing is done like the above lines ..Does that right?

I am not convinced it is the same. https://stackoverflow.com/questions/36428205/stress-attribute-sklearn-manifold-mds-python says the Python one uses sigma_r but mdscale uses sigma_1
