Understanding Fine Tuning Large Language Models

Pre-trained language models are big neural networks trained on tons of text from the internet. They learn by predicting missing words in sentences, helping them understand grammar and context. Fine-tuning is the next step, where these models get customized for specific tasks using particular datasets, making them even more effective.

Examples of popular pre-trained language models include BERT (Bidirectional Encoder Representations from Transformers), GPT-3 (Generative Pre-trained Transformer 3), RoBERTa (A Robustly Optimized BERT Pretraining Approach), and many more. These models are known for their ability to perform tasks such as text generation, sentiment classification, and language understanding at an impressive level of proficiency of these hyperparameters.

Let’s discuss one of the language models in detail.

GPT-3

GPT-3 Generative Pre-trained Transformer 3 is a ground-breaking language model architecture that has transformed natural language generation and understanding. The Transformer model is the foundation for the GPT-3 architecture, which incorporates several parameters to produce exceptional performance.

The Architecture of GPT-3

A stack of Transformer encoder layers makes up GPT-3. Multi-head self-attention mechanisms and feed-forward neural networks make up each layer. While the feed-forward networks process and transform the encoded representations, the attention mechanism enables the model to recognize dependencies and relationships between words.

The main innovation of GPT-3 is its enormous size, which allows it to capture a huge amount of language knowledge thanks to its astounding 175 billion parameters.

Architecture of GPT 3

Implementation of Code

You can use the OpenAI API to interact with the GPT- 3 model of openAI. Here is an example of text generation using GPT-3.

import openai

# Set up your OpenAI API credentials
openai.api_key = 'YOUR_API_KEY'

# Define the prompt for text generation
prompt = "A quick brown fox jumps"

# Make a request to GPT-3 for text generation
response = openai.Completion.create(
  engine="text-davinci-003",
  prompt=prompt,
  max_tokens=100,
  temperature=0.6
)

# Retrieve the generated text from the API response
generated_text = response.choices[0].text

# Print the generated text
print(generated_text)

Fine-Tuning: Tailoring Models to Our Needs

AI models are smart with words, but they need extra training to become experts at specific tasks like understanding feelings or translating languages. This is called fine-tuning, and it’s what makes these models really useful for different jobs.

Fine-tuning is like giving a final polish to versatile models. Think of it as helping a multi-talented friend focus on one specific skill for a special event. You would provide them with targeted training, just like we do with pre-trained language models during fine-tuning.

fine tuning large language model, llms Fine tunning

Fine-tuning large language models involves training the pre-trained model on a smaller, task-specific dataset. This new dataset is labeled with examples relevant to the target task. By exposing the model to these labeled examples, it can adjust its parameters and internal representations to become well-suited for the target task.

The Need for Fine-Tuning LLMs

Pre-trained language models are impressive, but they aren’t task-specific by default. Fine-tuning adapts these models for specialized tasks like sentiment analysis or domain-specific question answering. It enhances their accuracy by helping the model understand the nuances of a particular task. Fine-tuning offers two key benefits: it saves time and resources by leveraging pre-existing knowledge from pre-training, and it improves performance on specific tasks by focusing on domain-specific details.

Fine-Tuning LLMs Process: A Step-by-step Guide

The LLM fine-tuning process typically involves feeding the task-specific dataset to the pre-trained model and adjusting its parameters through backpropagation. The goal is to minimize the loss function, which measures the difference between the model’s predictions and the ground-truth labels in the dataset. This fine-tuning process updates the model’s parameters, making it more specialized for your target task.

Here we will walk through the process of instruction fine tuning a large language model for sentiment analysis. We’ll use the Hugging Face Transformers library, which provides easy access to pre-trained models and utilities for LLM fine tuning.

Step 1: Load the Pre-trained Language Model and Tokenizer

The first step is to load the pre-trained language model and its corresponding tokenizer. For this example, we’ll use the ‘distillery-base-uncased’ model, a lighter version of BERT.

from transformers import DistilBertTokenizer, DistilBertForSequenceClassification

# Load the pre-trained tokenizer
tokenizer = DistilBertTokenizer.from_pretrained('distilbert-base-uncased')

# Load the pre-trained model for sequence classification
model = DistilBertForSequenceClassification.from_pretrained('distilbert-base-uncased')

Step 2: Prepare the Sentiment Analysis Dataset

We need a labeled dataset with text samples and corresponding sentiments for sentiment analysis. Let’s create a small dataset for illustration purposes:

texts = ["I loved the movie. It was great!",
         "The food was terrible.",
         "The weather is okay."]
sentiments = ["positive", "negative", "neutral"]

Next, we’ll use the tokenizer to convert the text samples into token IDs, and attention masks the model requires.

# Tokenize the text samples
encoded_texts = tokenizer(texts, padding=True, truncation=True, return_tensors='pt')

# Extract the input IDs and attention masks
input_ids = encoded_texts['input_ids']
attention_mask = encoded_texts['attention_mask']

# Convert the sentiment labels to numerical form
sentiment_labels = [sentiments.index(sentiment) for sentiment in sentiments]

Step 3: Add a Custom Classification Head

The pre-trained language model itself doesn’t include a classification head. We must add one to the model to perform sentiment analysis. In this case, we’ll add a simple linear layer.

import torch.nn as nn

# Add a custom classification head on top of the pre-trained model
num_classes = len(set(sentiment_labels))
classification_head = nn.Linear(model.config.hidden_size, num_classes)

# Replace the pre-trained model's classification head with our custom head
model.classifier = classification_head

Step 4: Fine-Tune the Model

With the custom classification head in place, we can now fine-tune the model on the sentiment analysis dataset. We’ll use the AdamW optimizer and CrossEntropyLoss as the loss function.

import torch.optim as optim

# Define the optimizer and loss function
optimizer = optim.AdamW(model.parameters(), lr=2e-5)
criterion = nn.CrossEntropyLoss()

# Fine-tune the model
num_epochs = 3
for epoch in range(num_epochs):
    optimizer.zero_grad()
    outputs = model(input_ids, attention_mask=attention_mask, labels=torch.tensor(sentiment_labels))
    loss = outputs.loss
    loss.backward()
    optimizer.step()

What is Fine-tuning, and Why is it Important?

In machine learning, fine-tuning is the process of further training a previously learned model, such as a llama, on a particular task or dataset in order to enhance that model’s performance. With this method, the model’s prior learnings from a broad, all-purpose dataset are tapped into and tailored to the specifics of a given issue. This process is especially effective when using open source tools, as they provide a flexible and collaborative environment for experimentation and improvement. Additionally, validation is crucial during fine-tuning to ensure that the adjustments made to the model genuinely improve its performance on the targeted task.

Why it is Important?

Efficiency:

  • Time-consuming: Training a machine learning model from scratch can be very time-consuming and resource-intensive. Fine-tuning a pre-trained model, which has already learned many useful features from its initial training, requires significantly less time and computational effort.
  • Fine-tuning methods: These methods optimize the use of pre-trained models, enhancing efficiency by reducing the time and resources needed for training.

Enhanced Performance:

  • Training dataset: Pre-trained models have already extracted a large number of features and patterns from their original training dataset. Instruction fine tuning these models on a specific dataset helps them adapt to the unique characteristics of the data, often resulting in better performance compared to training a new model from scratch.
  • Tune LLMs: LLM fine Tuning large language models (LLMs) on specific datasets enhances their performance by allowing them to adjust to particular features of the data.

Data Scarcity:

  • Training dataset: There is often a scarcity of labeled data available for a specific task. Instruction fine tuning a model that has been trained on a large and diverse dataset helps achieve good performance even with limited labeled data.
  • Pre-trained models: Using pre-trained models mitigates the issue of data scarcity by leveraging the extensive training they have already undergone.

What is Instruction Fine tuning?

Instruction fine-tuning is a specialized technique to tailor large language models to perform specific tasks based on explicit instructions. While traditional LLM fine-tuning involves training a model on task-specific data, instruction fine-tuning goes further by incorporating high-level instructions or demonstrations to guide the model’s behavior.

"pre trained LLM , Fine-tuned LLM

This approach allows developers to specify desired outputs, encourage certain behaviors, or achieve better control over the model’s responses. In this comprehensive guide, we will explore the concept of instruction fine-tuning and its implementation step-by-step.

Instruction Finetuning Process

What if we could go beyond traditional instruction finetuning and provide explicit instructions to guide the model’s behavior? Instruction fine-tuning does that, offering a new level of control and precision over model outputs. Here we will explore the process of instruction fine-tuning large language models for sentiment analysis.

Step 1: Load the Pre-trained Language Model and Tokenizer

To begin, let’s load the pre-trained language model and its tokenizer. We’ll use GPT-3, a state-of-the-art language model, for this example.

from transformers import GPT2Tokenizer, GPT2ForSequenceClassification

# Load the pre-trained tokenizer
tokenizer = GPT2Tokenizer.from_pretrained('gpt2')

# Load the pre-trained model for sequence classification
model = GPT2ForSequenceClassification.from_pretrained('gpt2')

Step 2: Prepare the Instruction Data and Sentiment Analysis Dataset

For instruction fine-tuning, we need to augment the sentiment analysis dataset with explicit instructions for the model. Let’s create a small dataset for demonstration:

texts = ["I loved the movie. It was great!",
         "The food was terrible.",
         "The weather is okay."]
sentiments = ["positive", "negative", "neutral"]
instructions = ["Analyze the sentiment of the text and identify if it is positive.",
                "Analyze the sentiment of the text and identify if it is negative.",
                "Analyze the sentiment of the text and identify if it is neutral."]

Next, let’s tokenize the texts, sentiments, and instructions using the tokenizer:

# Tokenize the texts, sentiments, and instructions
encoded_texts = tokenizer(texts, padding=True, truncation=True, return_tensors='pt')
encoded_instructions = tokenizer(instructions, padding=True, truncation=True, return_tensors='pt')

# Extract input IDs, attention masks, and instruction IDs
input_ids = encoded_texts['input_ids']
attention_mask = encoded_texts['attention_mask']
instruction_ids = encoded_instructions['input_ids']

Step 3: Customize the Model Architecture with Instructions

To incorporate instructions during instruction finetuning, we need to customize the model architecture. We can do this by concatenating the instruction IDs with the input IDs:

import torch

# Concatenate instruction IDs with input IDs and adjust attention mask
input_ids = torch.cat([instruction_ids, input_ids], dim=1)
attention_mask = torch.cat([torch.ones_like(instruction_ids), attention_mask], dim=1)

Step 4: Fine-Tune the Model with Instructions

With the instructions incorporated, we can now fine-tune the GPT-3 model on the augmented dataset. During fine-tuning, the instructions will guide the model’s sentiment analysis behavior.

import torch.optim as optim

# Define the optimizer and loss function
optimizer = optim.AdamW(model.parameters(), lr=2e-5)
criterion = torch.nn.CrossEntropyLoss()

# Fine-tune the model
num_epochs = 3
for epoch in range(num_epochs):
    optimizer.zero_grad()
    outputs = model(input_ids, attention_mask=attention_mask, labels=torch.tensor(sentiments))
    loss = outputs.loss
    loss.backward()
    optimizer.step()

Instruction fine-tuning takes the power of traditional fine-tuning to the next level, allowing us to control the behavior of large language models precisely. By providing explicit instructions, we can guide the model’s output and achieve more accurate and tailored results.

Key Differences Between the Two Approaches

Standard fine-tuning involves training a model on a labeled dataset, honing its abilities to perform specific tasks effectively. However, when it comes to fine-tuning large language models like GPT-3.5, if we want to provide explicit instructions to guide the model’s behavior, instruction fine-tuning comes into play. This approach offers unparalleled control and adaptability, allowing us to tailor the model’s responses to meet specific criteria or address nuanced requirements

Here are the critical differences between instruction finetuning and standard finetuning.

  • Data Requirements: Standard fine-tuning relies on a significant amount of labeled data for the specific task, whereas instruction fine-tuning benefits from the guidance provided by explicit instructions, making it more adaptable with limited labeled data.
  • Control and Precision: Instruction fine-tuning allows developers to specify desired outputs, encourage certain behaviors, or achieve better control over the model’s responses. Standard fine-tuning may not offer this level of control.
  • Learning from Instructions: Instruction fine-tuning requires an additional step of incorporating instructions into the model’s architecture, which standard fine-tuning does not.

Introducing Catastrophic Forgetting: A Perilous Challenge

Fine-tuning large language models often leads to “catastrophic forgetting,” where a model loses valuable pre-trained knowledge while learning a new task. This happens because, during fine-tuning, the model focuses on the new task and unintentionally forgets broader language structures it previously learned. It’s like a ship’s crew rearranging cargo; some containers of knowledge get emptied to make room for new ones, causing some important information to be lost in the process.

Mitigating Catastrophic Forgetting: Safeguarding Knowledge

To navigate the waters of catastrophic forgetting, we need strategies to safeguard the valuable knowledge captured during pre-training. There are two possible approaches.

Multi-task Finetuning: Progressive Learning

  • Gradually introduce a new task to the model:
    • Start with the model’s existing knowledge from pre-training.
    • Slowly add data from the new task to prevent forgetting important information (catastrophic forgetting).
  • Use multitask instruction fine-tuning:
    • Train language models on multiple tasks at the same time instead of one at a time.
    • Provide clear instructions for each task to guide the model during training.
  • Benefits of this method:
    • It’s a breakthrough for refining large language models.
    • Allows for comprehensive training on several tasks simultaneously.
    • Improves the model’s learning process through specific instructions.
    • Enhances efficiency and seamlessly integrates various tasks, showcasing the flexibility and adaptability of language models.

Benefits of Multitask Instruction Fine-Tuning

  • Knowledge Transfer: The model gains insights and knowledge from different domains by training on multiple tasks, enhancing its overall language understanding.
  • Shared Representations: Multitask instruction fine-tuning allows the model to share representations across tasks. This sharing of knowledge improves the model’s generalization capabilities.
  • Efficiency: Training on multiple tasks concurrently reduces the computational cost and time compared to fine-tuning each task individually.

Parameter Efficient Finetuning: Transfer Learning

Here we freeze certain layers of the model during fine-tuning in large language models. By freezing early layers responsible for fundamental language understanding, we preserve the core knowledge while only fine-tuning later layers for the specific task and the specific use case.

Understanding PEFT

Memory is necessary for full fine-tuning to store the model and several other training-related parameters. You must be able to allocate memory for optimizer states, gradients, forward activations, and temporary memory throughout the training process, even if your computer can hold the model weight of hundreds of gigabytes for the largest models. These extra parts may be much bigger than the model and quickly outgrow the capabilities of consumer hardware.

LLM  with additional layers for PEFT

Parameter-efficient fine-tuning large language models techniques only update a small subset of parameters instead of full fine-tuning, which updates every model weight during supervised learning. Some path techniques concentrate on fine-tuning a portion of existing model parameters, such as specific layers or components, while freezing the majority of model weights. Other methods add a few new parameters or layers and only fine-tune the new components; they do not affect the original model weights. Most, if not all, LLM weights are kept frozen using PEFT. As a result, compared to the original LLM, there are significantly fewer trained parameters.

Why PEFT?

PEFT empowers parameter-efficient models with impressive performance, revolutionizing the landscape of NLP. Here are a few reasons why we use PEFT.

  • Reduced Computational Costs: PEFT requires fewer GPUs and GPU time, making it more accessible and cost-effective for training large language models.
  • Faster Training Times: With PEFT, models finish training faster, enabling rapid iterations and quicker deployment in real-world applications.
  • Lower Hardware Requirements: PEFT works efficiently with smaller GPUs and requires less memory, making it feasible for resource-constrained environments.
  • Improved Modeling Performance: PEFT produces more robust and accurate models for diverse tasks by reducing overfitting.
  • Space-Efficient Storage: With shared weights across tasks, PEFT minimizes storage requirements, optimizing model deployment and management.

Finetuning with PEFT

While freezing most pre-trained LLMs, PEFT only approaches fine-tuning a few model parameters, significantly lowering the computational and storage costs. This also resolves the problem of catastrophic forgetting, which was seen during LLMs’ full fine-tuning.

In low-data regimes, PEFT approaches have also been demonstrated to be superior to fine-tuning and to better generalize to out-of-domain scenarios.

Loading the Model

Let’s load the opt-6.7b model here; its weights on the Hub are roughly 13GB in half-precision( float16). It will require about 7GB of memory if we load them in 8-bit.

import os
os.environ["CUDA_VISIBLE_DEVICES"]="0"
import torch
import torch.nn as nn
import bitsandbytes as bnb
from transformers import AutoTokenizer, AutoConfig, AutoModelForCausalLM

model = AutoModelForCausalLM.from_pretrained(
    "facebook/opt-6.7b", 
    load_in_8bit=True, 
    device_map='auto',
)

tokenizer = AutoTokenizer.from_pretrained("facebook/opt-6.7b")

Postprocessing On the Model

Let’s freeze all our layers and cast the layer norm in float32 for stability before applying some post-processing to the 8-bit model to enable training. We also cast the final layer’s output in float32 for the same reasons.

for param in model.parameters():
  param.requires_grad = False  # freeze the model - train adapters later
  if param.ndim == 1:
    param.data = param.data.to(torch.float32)

model.gradient_checkpointing_enable()  # reduce number of stored activations
model.enable_input_require_grads()

class CastOutputToFloat(nn.Sequential):
  def forward(self, x): return super().forward(x).to(torch.float32)
model.lm_head = CastOutputToFloat(model.lm_head)

Using LoRA

Load a PeftModel, we will use low-rank adapters (LoRA) using the get_peft_model utility function from Peft.

The function calculates and prints the total number of trainable parameters and all parameters in a given model. Along with the percentage of trainable parameters, providing an overview of the model’s complexity and resource requirements for training.

def print_trainable_parameters(model):
 
    # Prints the number of trainable parameters in the model.
   
    trainable_params = 0
    all_param = 0
    for _, param in model.named_parameters():
        all_param += param.numel()
        if param.requires_grad:
            trainable_params += param.numel()
    print(
        f"trainable params: {trainable_params} || all params: {all_param} || 
          trainable%: {100 * trainable_params / all_param}"
    )

This uses the Peft library to create a LoRA model with specific configuration settings, including dropout, bias, and task type. It then obtains the trainable parameters of the model and prints the total number of trainable parameters and all parameters, along with the percentage of trainable parameters.

from peft import LoraConfig, get_peft_model 

config = LoraConfig(
    r=16,
    lora_alpha=32,
    target_modules=["q_proj", "v_proj"],
    lora_dropout=0.05,
    bias="none",
    task_type="CAUSAL_LM"
)

model = get_peft_model(model, config)
print_trainable_parameters(model)

Training the Model

This uses the Hugging Face Transformers and Datasets libraries to train a language model on a given dataset. It utilizes the ‘transformers.Trainer’ class to define the training setup, including batch size, learning rate, and other training-related configurations and then trains the model on the specified dataset.

import transformers
from datasets import load_dataset
data = load_dataset("Abirate/english_quotes")
data = data.map(lambda samples: tokenizer(samples['quote']), batched=True)

trainer = transformers.Trainer(
    model=model, 
    train_dataset=data['train'],
    args=transformers.TrainingArguments(
        per_device_train_batch_size=4, 
        gradient_accumulation_steps=4,
        warmup_steps=100, 
        max_steps=200, 
        learning_rate=2e-4, 
        fp16=True,
        logging_steps=1, 
        output_dir='outputs'
    ),
    data_collator=transformers.DataCollatorForLanguageModeling(tokenizer, mlm=False)
)
model.config.use_cache = False  # silence the warnings. Please re-enable for inference!
trainer.train()

In the real world, fine-tuning large language models is widely used across industries. It empowers businesses and researchers to harness NLP capabilities for various tasks. This leads to enhanced efficiency, improved decision-making, and enriched user experiences.

Retrieval Augmented Generation (RAG) approach?

RAG stands for Retrieval Augmented Generation, a method that improves the performance of large language models (LLMs). This is an explanation of how it functions:

A Weakness of LLMs:

Large-scale text and code datasets are used to train LLMs. This enables them to accomplish amazing tasks like text generation, language translation, and composing creative content. However, they may struggle to maintain factual accuracy and an up-to-date knowledge base.

RAG Comes to Help:

RAG combines an LLM with an information retrieval system. When a user submits a query, RAG first gathers pertinent materials from a trustworthy knowledge base (such as Wikipedia or an organization’s internal knowledge repository). The original query is then sent to the LLM along with these documents. Given this further background, the LLM, utilizing its base model, processes the query more accurately.

Metrics play a crucial role in evaluating the performance of these models. Embedding techniques are employed to represent the documents and queries in a high-dimensional space, making the retrieval process efficient and relevant. Python is often used to implement these complex algorithms and manage the integration between the retrieval system and the LLM. Technologies like ChatGPT exemplify the practical applications of RAG, showcasing enhanced accuracy and context awareness in generating responses.

Conclusion

Fine-tuning large language models has emerged as a powerful technique to adapt these pre-trained models to specific tasks and domains. As the field of NLP advances, fine-tuning will remain crucial to developing cutting-edge language models and applications.
