span-marker-bert-base-multilingual-cased-multinerd

This model is a fine-tuned version of bert-base-multilingual-cased on an Babelscape/multinerd dataset.

Is your data not (always) capitalized correctly? Then consider using the uncased variant of this model instead for better performance: lxyuan/span-marker-bert-base-multilingual-uncased-multinerd.

This model achieves the following results on the evaluation set:

  • Loss: 0.0049
  • Overall Precision: 0.9242
  • Overall Recall: 0.9281
  • Overall F1: 0.9261
  • Overall Accuracy: 0.9852

Test set results:

  • test_loss: 0.005226554349064827,
  • test_overall_accuracy: 0.9851129807294873,
  • test_overall_f1: 0.9270450073152169,

  • test_samples_per_second: 150.748,
  • test_steps_per_second: 4.711

This is a replication of Tom's work. Everything remains unchanged, except that we extended the number of training epochs to 3 for a slightly longer training duration and set the gradient_accumulation_steps to 2. Please refer to the official model page to review their results and training script
