Trainer

Use specialized models trained specifically for the rare language. 6. **Hybrid Approach**: Combine the strengths of multilingual models with language-specific models. 7. **Fallback Mechanisms**: Implement fallback mechanisms to h…

#### 1. Data Preprocessing ```python from transformers import LlamaTokenizer import torch # Load tokenizer tokenizer = LlamaTokenizer.from_pretrained("llama-2-13b") # Tokenize dataset def tokenize_function(examples): return tokenizer…

- **Strategy**: Use `True` if your hardware supports it (e.g., NVIDIA GPUs with Tensor Cores). ### Example Configuration Here's an example configuration for fine-tuning Llama 2 13B: ```python from transformers import LlamaForCausalLM…

from transformers import ( AutoModelForSequenceClassification, AutoTokenizer, Trainer, TrainingArguments, DataCollatorWithPadding, ) from datasets import load_dataset, DatasetDict # Load the model and tokenizer model_na…

- The `reformulate` function takes an input query, encodes it with the tokenizer, and generates a reformulated query using the model. 3. **Prefix for Task Guidance**: - The prefix `"reformulate: "` guides the model on the task at han…

item = {key: torch.tensor(val[idx]) for key, val in self.encodings.items()} item['labels'] = torch.tensor(self.labels[idx]) return item def __len__(self): return len(self.labels) train_dataset = TokenDa…

3. **Evaluate Accuracy**: Implement a function to evaluate the accuracy of the tokenization against ground truth labels. 4. **Fine-Tuning Example**: Prepare training data, convert it to a PyTorch dataset, and fine-tune the model using the `…
