BERT Fine-Tuned on TREC

A fine-tuned BERT model using the TREC dataset with coarse-grained labels.

Model Details

Description

This model is based on the BERT base (uncased) architecture and has been fine-tuned on the TREC dataset using coarse-grained labels.

Training Details

Fine-tuning was performed end-to-end using a grid search over key hyperparameters. Model performance was evaluated based on validation loss computed on the development set. After identifying the optimal hyperparameter configuration, the final model was retrained on the entire training dataset.

Training Data

The model was trained on the TREC training partition using coarse-grained labels, with validation performed on a random 20% split of the training data.

Training Hyperparameters

• —Epochs: 1-4
• —Batch size: {16, 32}
• —Learning rate: {5e-5, 3e-5, 2e-5}
• —Validation metric: loss
• —Precision: fp16

Uses

This model can be used for classification tasks aligned with the structure and intent of the TREC dataset.

For broader guidance, refer to the BERT base model’s Inteded Uses & Limitations.

Bias, Risks, and Limitations

This model inherits the potential risks and limitations of its base model. For more details, refer to the Limitations and bias section of the original model documentation.

Additionally, it may reflect or amplify patterns and biases present in the TREC training data.

Hardware

• —Hardware Type: NVIDIA Tesla V100 PCIE 32GB
