What is Parameter-efficient Fine-tuning (PEFT)?
If you’re familiar with transfer learning, you know that it’s a powerful technique that allows you to leverage pre-trained models to solve a wide range of downstream tasks. However, fine-tuning these models can be computationally expensive, especially when dealing with large models like GPT-3 or BERT that have billions of parameters.
This is where Parameter-efficient Fine-tuning (PEFT) comes in. PEFT is a set of techniques that propose to fine-tune large pre-trained models using a small subset of parameters while preserving most of the original pre-trained weights fixed. By fine-tuning only a small subset of the model’s parameters, you can achieve comparable performance to full fine-tuning while significantly reducing computational requirements.
![Did you know- PEFT](data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIxOTIwIiBoZWlnaHQ9IjY0MCIgdmlld0JveD0iMCAwIDE5MjAgNjQwIj48cmVjdCB3aWR0aD0iMTAwJSIgaGVpZ2h0PSIxMDAlIiBzdHlsZT0iZmlsbDojY2ZkNGRiO2ZpbGwtb3BhY2l0eTogMC4xOyIvPjwvc3ZnPg==)
PEFT approaches are beneficial when you have limited computational resources or when you need to fine-tune a model on a specific task quickly. With PEFT, you can fine-tune a model using only a fraction of the resources required for full fine-tuning, making it a cost-effective and efficient solution.
To use PEFT, you first need to identify the subset of parameters that you want to fine-tune. This can be done by analyzing the specific task you want to solve and identifying the parameters that are most relevant to that task. Once you have identified the subset of parameters, you can fine-tune them using a small amount of data, typically in the range of a few hundred examples.
PEFT has become an increasingly popular technique in the field of Natural Language Processing (NLP), where large pre-trained models like GPT-3 and BERT are commonly used. With PEFT, researchers and practitioners can fine-tune these models on specific NLP tasks with much less computational resources than full fine-tuning.

What are the Differences Between Fine-tuning and PEFT?
Criteria | Fine-Tuning | Parameter-Efficient Fine-Tuning (PEFT) |
Parameter Updates | Updates most or all parameters of the model. | Updates a small subset of parameters or adds a few trainable layers. |
Computational Cost | High; requires significant computational resources. | Lower; designed to minimize computational demands. |
Storage Requirements | High; each fine-tuned model variant requires full storage of all parameters. | Reduced; stores only a fraction of the full model parameters. |
Scalability | Less scalable due to high resource demands. | More scalable, especially on consumer-grade hardware. |
Model Size | Trained model size increases slightly or significantly depending on the dataset. | Trained model size remains closer to the pre-trained model’s size. |
Performance | Can achieve higher performance on the new task, especially with large datasets. | May achieve slightly lower performance compared to full fine-tuning, but often comparable. |

Large Language Models and PEFT
Large Language Models (LLMs) are models that have millions or even billions of parameters. They are pre-trained on vast amounts of text data and can be fine-tuned for specific NLP tasks with a relatively small amount of task-specific data. However, training and fine-tuning LLMs can be computationally expensive and require a significant amount of memory.
PEFT, or Parameter-efficient Fine-tuning, is a technique designed to address these issues. PEFT approaches only fine-tune a small number of extra model parameters while freezing most parameters of the pre-trained LLMs. This greatly decreases the computational and storage costs and overcomes the issues of catastrophic forgetting, a phenomenon where the model forgets previously learned information when fine-tuned on a new task.
Role of Pre-Trained Models
Pre-trained models play a crucial role in PEFT. They provide a starting point for fine-tuning and allow for efficient transfer learning. Pre-trained models are trained on large amounts of text data, and their parameters are optimized to capture general language patterns. This pretraining enables the model to perform well on a range of NLP tasks without the need for extensive task-specific training.
PEFT builds on this pretraining by fine-tuning the model on a specific task using a small amount of task-specific data. This fine-tuning process allows the model to learn task-specific information while retaining its general language understanding.
Parameters
PEFT’s parameter-efficient approach is achieved by freezing most of the pre-trained model’s parameters and only fine-tuning a small number of extra model parameters. This greatly reduces the amount of memory required for fine-tuning and makes it possible to fine-tune large models on smaller hardware.
The number of extra parameters that are fine-tuned in PEFT depends on the task and the amount of task-specific data available. In general, the more task-specific data available, the fewer extra parameters need to be fine-tuned.

8 Key Parameter-efficient Fine-tuning Techniques
Fine-tuning pre-trained models allows them to excel at specific tasks. Here are some of popular methods, along with their strengths:
1. Adapter Modules
Imagine attaching task-specific modules onto a pre-trained LLM. That’s the essence of adapter modules. These lightweight modules are trained on the new task data without modifying the core LLM parameters. This approach is particularly effective for tasks requiring moderate additional context, such as sentiment analysis or named entity recognition (NER). Popular examples include:
- Conditional Adapter Network (CAN): Introduces a single adapter module that adapts to different tasks based on a task-conditioning input.
- Adapter-Tuning: Employs multiple adapter modules placed strategically throughout the LLM architecture to capture task-specific information.
2. LoRA Techniques
LoRA modifies a pre-trained model by introducing low-rank matrices that approximate the updates to the model’s weights. During fine-tuning, these low-rank matrices are adjusted instead of the full weight matrices. This reduces the number of trainable parameters and can significantly cut down on memory usage and computational costs. Here are two popular approaches:
- Low-Rank Matrix Factorization: This technique decomposes weight matrices in the LLM architecture into lower-rank matrices, effectively compressing the information stored within them.
- Randomized Parameter Sharing: Randomly shares weights across different parts of the model, reducing the overall number of unique parameters needed.
![Parameter-efficient Fine-tuning](data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIxMDI0IiBoZWlnaHQ9IjU3NiIgdmlld0JveD0iMCAwIDEwMjQgNTc2Ij48cmVjdCB3aWR0aD0iMTAwJSIgaGVpZ2h0PSIxMDAlIiBzdHlsZT0iZmlsbDojY2ZkNGRiO2ZpbGwtb3BhY2l0eTogMC4xOyIvPjwvc3ZnPg==)
3. Prompt Tuning
Prompt tuning involves appending a sequence of trainable parameters (prompts) to the input of a model. The model then learns to perform a specific task by adjusting these prompts while keeping the main model parameters unchanged. This technique leverages the idea that large language models are highly sensitive to their input format, making it possible to steer the model’s behavior with carefully designed prompts. This is highly efficient as it requires tuning only a tiny fraction of the total parameters.
4. Prefix Tuning
Similar to prompt tuning, prefix tuning adds a sequence of trainable vectors (prefixes) at the beginning of the input sequence. Unlike prompts that are added to the actual input text, prefixes are additional, separate tokens that precede the input and are optimized during training. This method allows the model to learn task-specific adjustments without altering the pre-trained weights directly.

5. P-Tuning
P-tuning fine-tunes the pre-trained model on task data, but limits updates to a specific subset of its parameters. This method is well-suited for context-heavy tasks like language modeling and machine translation, offering good performance while keeping resource consumption in check.
6. Diff Pruning
Diff Pruning is a technique where a sparse mask is applied to the model’s parameters, determining which parameters will be updated during the training process. This creates a sparse differential update on top of the pre-trained model, allowing for efficient fine-tuning with a limited impact on the model’s parameter count.
7. Compacter
Compacter combines the principles of adapters and compact transformations. It uses hypercomplex multiplications to create efficient adapter layers with fewer parameters. This method extends the adapter approach by further reducing the parameter count through the use of mathematical transformations that compress the adapter’s weight matrices.
8. IA3
The IA3 (Iterative Amortized Attention and Alignment) technique is a more specialized approach within the realm of parameter-efficient fine-tuning for natural language processing models. It’s designed to optimize the process of aligning and adapting pre-trained models to new tasks or datasets with high efficiency. It focuses on the efficient alignment of pre-trained model embeddings with task-specific embeddings. The key idea is to iteratively adjust a small set of parameters that control the alignment between the base model’s understanding of language and the specific requirements of the new task.

Benefits of Parameter-efficient Fine-tuning
In the context of Natural Language Processing (NLP), pre-trained language models (LLMs) have become critical, capable of tackling diverse tasks. However, fine-tuning these behemoths often comes at a hefty cost – immense computational resources and storage needs. This is where Parameter-efficient Fine-tuning (PEFT) steps in, offering a compelling solution. Below are key benefits PEFT brings to the table:
1. Reduced Computational Cost and Faster Training
PEFT fine-tunes only a small subset of the pre-trained model’s parameters, focusing on aspects most relevant to the new task. This significantly reduces the computational power required for training, leading to faster training times. Imagine training a model on your local machine instead of needing a powerful server – that’s the kind of efficiency PEFT offers.
2. Lower Storage Requirements
Large, fine-tuned models can be cumbersome to store. PEFT, by keeping most pre-trained parameters untouched, results in a smaller final model size. This translates to lower storage needs, making deployment on resource-constrained devices (e.g., mobile phones) more feasible.
3. Combating Catastrophic Forgetting
Full fine-tuning can sometimes lead to “catastrophic forgetting,” where the model loses its previously learned knowledge from pre-training. PEFT mitigates this risk by leaving most pre-trained parameters intact, ensuring the model retains its foundational knowledge while adapting to the new task.
4. Improved Performance in Data-Scarce Scenarios
Large datasets are often required for successful fine-tuning. PEFT shines in situations with limited data. By focusing on a smaller parameter set, PEFT can often achieve better performance on small datasets compared to full fine-tuning, which might struggle to learn effectively with limited data points.
5. Enhanced Portability and Deployment
PEFT-tuned models are typically smaller in size, making them easier to distribute and deploy across different platforms. This allows you to readily transfer the model to new tasks or environments without needing to retrain the entire model from scratch.
6. A More Sustainable Approach
The significant computational resources required for traditional fine-tuning can have a considerable environmental impact. PEFT’s reduced training time and lower resource consumption make it a more sustainable approach to NLP tasks.

Computational Aspects of PEFT
When it comes to fine-tuning large language models (LLMs), computational requirements can be a significant challenge. However, parameter-efficient fine-tuning (PEFT) aims to address this issue by fine-tuning only a small number of extra model parameters while freezing most of the pre-trained LLMs’ parameters. This greatly reduces computational and storage costs.
PEFT methods overcome the issues of catastrophic forgetting, a behavior observed during the full fine-tuning of LLMs. With PEFT, the base model weights are frozen, and a few trainable adapter modules are injected into the model, resulting in a very small number of trainable weights (<<1%). By only fine-tuning a few parameters, PEFT reduces the computational requirements and makes it possible to fine-tune LLMs on smaller hardware.
PEFT also allows for the efficient adaptation of pre-trained language models (PLMs) to various downstream applications without fine-tuning all the model’s parameters. You can achieve this by only fine-tuning a small number of extra model parameters, significantly decreasing computational and storage costs.
In addition to reducing computational requirements, PEFT also helps to minimize the adaptation cost for downstream tasks. While many PEFT techniques have been proposed for language and 2D image pre-trained models, specialized PEFT methods for 3D pre-trained models are still under-explored.
PEFT is a promising technique for fine-tuning LLMs while minimizing computational requirements and reducing adaptation costs for downstream tasks. By fine-tuning only a few extra model parameters, PEFT makes it possible to fine-tune LLMs on smaller hardware, making the technique accessible to a wider range of researchers and practitioners.

Pitfalls to avoid in PEFT
When using Parameter-efficient Fine-tuning (PEFT) to fine-tune a pre-trained model, there are some pitfalls that you should be aware of to avoid suboptimal results. Here are some key things to keep in mind:
1. Overfitting
Since PEFT only fine-tunes a small number of extra parameters, it is possible to overfit the model to the training data. To avoid overfitting, it is important to use regularization techniques such as weight decay and dropout. You can also monitor the validation loss during training to detect overfitting and stop the training early if necessary.
2. Choosing the Right Adapter Size
PEFT uses adapter modules to add new functionality to a pre-trained model. Choosing the right adapter size is crucial for achieving good performance. If the adapter is too small, it may not be able to capture the necessary information. On the other hand, if the adapter is too large, it may lead to overfitting. A good rule of thumb is to choose an adapter size roughly 10% of the size of the pre-trained model.
3. Choosing the Right Learning Rate
Choosing the right learning rate is important for achieving good performance in PEFT. If the learning rate is too high, it may cause the model to diverge. If the learning rate is too low, it may cause the model to converge too slowly. A good approach is to use a learning rate schedule that gradually decreases the learning rate over time.
4. Choosing the Right Pre-trained Model
Not all pre-trained models are created equal. Some models may be better suited for certain tasks than others. When choosing a pre-trained model for fine-tuning with PEFT, it is important to consider factors such as the size of the model, the quality of the pretraining data, and the performance of similar tasks.
Here’s a list of pre-trained models where Parameter-Efficient Fine-Tuning (PEFT) techniques have been applied:
- BERT (Bidirectional Encoder Representations from Transformers)
- GPT-3 (Generative Pre-trained Transformer 3)
- T5 (Text-to-Text Transfer Transformer)
- RoBERTa (A Robustly Optimized BERT Pretraining Approach)
- XLNet
- ELECTRA
- ALBERT (A Lite BERT)
