To optimize token embeddings in a transformer model for generating complex language structures, use dynamic embedding updates (fine-tuning), subword tokenization (BPE/WordPiece), retrieval-augmented embeddings, contrastive learning, and disentangled representations.
Here is the code snippet you can refer to:
In the above code we are using the following key approaches:
-
Fine-Tunes Token Embeddings with Domain-Specific Data:
- Uses the Wikitext-103 dataset for adaptive learning.
- Retrains token embeddings dynamically for better contextual understanding.
-
Efficient Tokenization Strategy (BPE):
- GPT-2 uses Byte-Pair Encoding (BPE) to optimize subword tokenization.
- Ensures complex language structures are encoded efficiently.
-
Hyperparameter Optimization for Embeddings:
- Weight Decay (0.01): Prevents overfitting in embeddings.
- Learning Rate (5e-5): Ensures smooth adaptation without overwriting pre-trained knowledge.
-
Data Collation & Masking:
- Uses DataCollatorForLanguageModeling to dynamically mask input tokens for robust training.
Hence, fine-tuning embeddings, leveraging advanced tokenization, and integrating retrieval-based methods enhance transformer-generated complex language structures, improving both fluency and coherence.
