Training procedure
The training process described in Experiment 3 focuses on fine-tuning the pre-trained mBERT (multilingual BERT) model for improving raw handwritten text recognition (HTR). The fine-tuning dataset consists of raw HTR outputs paired with their human-corrected ground truth, as indicated in the line.csv file.
Key Parameters and Rationale:
1. Model Selection: The use of bert-base-multilingual-cased leverages the multilingual capabilities of BERT to accommodate the linguistic diversity likely present in the handwritten text dataset. This choice aligns well with the need to handle potentially mixed-language inputs or varying character distributions.
2. Data Handling:
- The dataset is loaded and structured into columns for raw HTR text and its hand-corrected counterpart.
- Tokenization is performed using the mBERT tokenizer, with a maximum sequence length of 64 tokens. This length balances capturing sufficient context while preventing memory overhead.
3. Training Configuration:
Batch Size and Gradient Accumulation: A batch size of 4 with a gradient accumulation step of 1 is chosen, likely due to the memory limitations of the L4 GPU, ensuring stable training while processing smaller data chunks.
Learning Rate and Weight Decay: A low learning rate of 5e-6 allows for gradual updates to the pre-trained weights, preserving the pre-trained linguistic knowledge while adapting to the new task. Weight decay is set to 0 to avoid penalizing model parameters unnecessarily for this specific task.
Gradient Clipping: The maximum gradient norm of 1 prevents exploding gradients, which could destabilize training given the small batch size and high learning rate sensitivity.
Warm-Up Steps: 300 warm-up steps allow the optimizer to start with smaller updates, reducing initial instability.
Epochs and Logging: The model is trained for 10 epochs with evaluation loss logged every 100 steps, providing a balance between sufficient training time and monitoring. Compute Setup:
The process was executed on an L4 GPU, which is optimized for such NLP workloads, providing efficient computation and faster training iterations.
