# distilbert-truncated

This model is a fine-tuned version of [distilbert-base-uncased](https://huggingface.co/distilbert-base-uncased) on the [20 Newsgroups dataset](http://qwone.com/~jason/20Newsgroups/).
It achieves the following results on the evaluation set:


## Training and evaluation data

The data was split into training and testing: model trained on 90% of the data, and had a testing data size of 10% of the original dataset.

## Training procedure

DistilBERT has a maximum input length of 512, so with this in mind the following was performed:

1. I used the `distilbert-base-uncased` pretrained model to initialize an `AutoTokenizer`.
2. Setting a maximum length of 256, each entry in the training, testing and validation data was truncated if it exceeded the limit and padded if it didn't reach the limit.

### Training hyperparameters

The following hyperparameters were used during training:
- optimizer: {'name': 'Adam', 'weight_decay': None, 'clipnorm': None, 'global_clipnorm': None, 'clipvalue': None, 'use_ema': False, 'ema_momentum': 0.99, 'ema_overwrite_frequency': None, 'jit_compile': True, 'is_legacy_optimizer': False, 'learning_rate': {'class_name': 'PolynomialDecay', 'config': {'initial_learning_rate': 2e-05, 'decay_steps': 1908, 'end_learning_rate': 0.0, 'power': 1.0, 'cycle': False, 'name': None}}, 'beta_1': 0.9, 'beta_2': 0.999, 'epsilon': 1e-08, 'amsgrad': False}
- training_precision: float32
