[P] 2,000x Faster RAPIDS TSNE – 3 hours down to 5 seconds on NVIDIA GPUs

[P] 2,000x Faster RAPIDS TSNE - 3 hours down to 5 seconds on NVIDIA GPUs

TSNE is a very popular data visualization algorithm used alongside PCA and UMAP.

Sklearn’s TSNE is very effective for small datasets, but on the 60,000 MNIST Digits dataset, expect to wait 1 hour. With RAPIDS cuML, TSNE on MNIST runs in 3 seconds!

On 200,000 rows, Sklearn takes a whopping 3 hours, whilst RAPIDS takes 5 seconds! (2,000x faster).

Figure 1. cuML TSNE on MNIST Fashion takes 3 seconds. Scikit-Learn takes 1 hour.

Check out my blog showcasing how cuML achieves this massive performance boost, and how NVIDIA GPUs can help scientists and engineers save their precious time.

Give cuML a try! You might know me as the author of HyperLearn, and I can say cuML is the gold standard package for machine learning on GPUs!

Linear Regression, UMAP, K-Means, DBSCAN etc are all sped up on the GPU! If you have any questions, feel free to ask!

Table 1. cuML’s TSNE time running on an NVIDIA DGX-1 with using 1 V100 GPU.

Finally, a big drawback of current GPU implementations is its memory consumption. With cuML TSNE, we use 30% less GPU memory! In a future release, this will be shaved by 33% again to a total of 50% memory reductions! We will also support PCA initialization.
