General Topic Classifier for Short-to-Medium Length Text

One model, 16 classes, 3M+ rows of labelled data

The infererence-optimised onnx model "onnx_optimised_mpnet_trained" to be deployed here, and is created from training/
The optimised model runs reasonably fast on CPU as well.
See training/README.md for details on dataset, training & benchmarks.

The model deployed here is based on MPNet (https://arxiv.org/abs/2004.09297), and has been fine-tuned on 3M+ data rows. It classifies short-to-medium length text into one of the 16 general topics:

• entertainment & music
• health 
• business & finance 
• sports 
• religion 
• pets & animals 
• family & relationships 
• food 
• travel 
• education & reference 
• politics & government 
• society & culture 
• mundane 
• computers & internet 
• science & mathematics 
• others
