# T5-base-finetuned-rte

<!-- Provide a quick summary of what the model is/does. -->

This model is T5 fine-tuned on GLUE RTE dataset. It acheives the following results on the validation set
- Accuracy: 0.7690


## Model Details
T5 is an encoder-decoder model pre-trained on a multi-task mixture of unsupervised and supervised tasks and for which each task is converted into a text-to-text format. 

## Training procedure

### Tokenization
Since, T5 is a text-to-text model, the labels of the dataset are converted as follows:
For each example, a sentence as been formed as **"rte sentence1: " + rte_sent1 + "sentence 2: " + rte_sent2** and fed to the tokenizer to get the **input_ids** and **attention_mask**.
For each label, target is choosen as **"entailment"** if label is 0, else label is **"not_entailment"** and tokenized to get **input_ids** and **attention_mask** . 
  During training, these inputs_ids having **pad** token are replaced with -100 so that loss is not calculated for them. Then these input ids are given as labels, and above attention_mask of labels
  is given as decoder attention mask.

### Training hyperparameters

The following hyperparameters were used during training:
- learning_rate: 3e-4
- train_batch_size: 16
- eval_batch_size: 16
- seed: 42
- optimizer: epsilon=1e-08
- num_epochs: 3.0
