Previous attempts to use GPUs have relied on coarse-grained task parallelism and have yielded inconclusive or unsatisfying results. We introduce CudaTree, a GPU Random Forest implementation which adaptively switches between data and task parallelism. We show that, for larger datasets, this algorithm is faster than highly tuned multi-core CPU implementations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Random Forests are a popular and powerful machine learning technique, with several fast multi-core CPU implementations.
