# Recommendation as Language Processing (RLP): A Unified Pretrain, Personalized Prompt & Predict Paradigm (P5)

This repo presents implementation of the **P5** large language model (LLM) for recommendation:

> **Paper link**: [https://arxiv.org/pdf/2203.13366.pdf](https://arxiv.org/pdf/2203.13366.pdf)

A reorganized and simplified repo of P5 called **OpenP5** is also available on GitHub, which is an open-source library for benchmarking foundation models for recommendation under the Pre-train, Personalized Prompt and Predict Paradigm (P5):

## Introduction
We present a flexible and unified Big Foundation Model for recommendation, which is the "Pretrain, Personalized Prompt, and Predict Paradigm" (**P5**) for recommendation. It unifies various recommendation tasks in a shared framework. In P5, all data such as user-item interactions, item metadata, and user reviews are converted to a common format -- natural language sequences. Specifically, P5 learns different tasks with the same language modeling objective during pretraining. Thus, it serves as the foundation model for downstream recommendation tasks, allows easy integration with other modalities, and enables instruction-based recommendation based on prompts. P5 advances recommender systems from shallow model to deep model to big model, and will revolutionize the technical form of recommender systems towards universal recommendation engine. With adaptive personalized prompt for different users, P5 is able to make predictions in a zero-shot or few-shot manner and largely reduces the necessity for extensive fine-tuning. On several recommendation benchmarks, we conduct experiments to show the effectiveness of P5. To help advance future research on Recommendation as Language Processing (RLP), Personalized Foundation Models (PFM), and Universal Recommendation Engine (URE), the source code, dataset, prompts, and pretrained P5 models are relased at this repository.

## Requirements:
- Python 3.9.7
- PyTorch 1.10.1
- transformers 4.2.1
- tqdm
- numpy
- sentencepiece
- pyyaml

## Usage

0. Clone this repo

```
    git clone https://github.com/jeykigung/P5.git
    ```

1. Download preprocessed data from this [Google Drive link](https://drive.google.com/file/d/1qGxgmx7G_WB7JE4Cn_bEcZ_o_NAJLE3G/view?usp=sharing), then put them into the *data* folder. If you would like to preprocess your own data, please follow the jupyter notebooks in the *preprocess* folder. Raw data can be downloaded from this [Google Drive link](https://drive.google.com/file/d/1uE-_wpGmIiRLxaIy8wItMspOf5xRNF2O/view?usp=sharing), then put them into the *raw_data* folder.

2. Download pretrained checkpoints into *snap* folder. If you would like to train your own P5 models, *snap* folder will also be used to store P5 checkpoints.

3. Pretrain with scripts in *scripts* folder, such as

```
    bash scripts/pretrain_P5_base_beauty.sh 4
    ```
   Here *4* means using 4 GPUs to conduct parallel pretraining.
    
4. Evaluate with example jupyter notebooks in the *notebooks* folder. Before testing, create a soft link of *data* folder to the *notebooks* folder by
   
   ```
   cd notebooks
   ln -s ../data .
   ```

## Pretrained Checkpoints
See [CHECKPOINTS.md](snap/CHECKPOINTS.md).

You can also explore P5 in Hugging Face Hub (https://huggingface.co/makitanikaze/P5).
