I wish academics would publish pure python implementations of their &quot;new&quot; algorithms. Standard python with Pypy is enough for speed of development and runtime.<p>The biggest thing about t-SNE is that it&#x27;s been used in competitive machine learning for quite a long time successfully by many different people because it&#x27;s on R via CRAN and Python via sklearn. LargeVis has potential, but it could also be not so useful like the vast majority of academic work.
