T5-base-finetuned-cola

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

This model is T5 fine-tuned on GLUE CoLA dataset. It acheives the following results on the validation set

• Matthews Correlation Coefficient: 0.5869

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 "cola sentence: " + cola_sent and fed to the tokenizer to get the input_ids and attention_mask. For each label, label is choosen as "acceptable" if label is 1, else label is "unacceptable" 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: 32
• eval_batch_size: 32
• seed: 42
• optimizer: epsilon=1e-08
• num_epochs: 3.0
