BERT Fine-Tuned on IMDb

A fine-tuned BERT model using the IMDb dataset.

Model Details

Description

This model is based on the BERT base (uncased) architecture and has been fine-tuned on the IMDb dataset.

• Developed by: Cesar Gonzalez-Gutierrez
• Funded by: ERC
• Architecture: BERT-base
• Base model: BERT base model (uncased)
• Language: English
• License: Apache 2.0

Seed Initializations

Alternative models trained using different initialization seeds are available and can be accessed using specific branches:

Random Seed	Branch
120	seed-120
220	seed-220
320	seed-320
420	seed-420
520	seed-520

To load a model from a specific branch, use the revision parameter:

from transformers import AutoModelForSequenceClassification

model = AutoModelForSequenceClassification.from_pretrained("<model>", revision="seed-120")

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 IMDb training partition, 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 IMDb corpus.

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 IMDb training data.
