title: How to select number of dimensions in t-SNE algorithm
body: <p>For PCA we can see variance_score and say how much percentage of original data variance is included in each Principal Components. With these variance scores, we can plot an elbow graph and decide the dimension for visualising data. But for t-SNE, I couldnt find any.
  Is there any way to decide the number of dimensions in t-SNE?</p>
