-    "BlazingText also supports a *supervised* mode for text classification. It extends the FastText text classifier to leverage GPU acceleration using custom CUDA kernels. The model can be trained on more than a billion words in a couple of minutes using a multi-core CPU or a GPU, while achieving performance on par with the state-of-the-art deep learning text classification algorithms.
