What is recommendation system ?

• Recommendation system helps users quickly find useful and interesting information from massive data.

• Recommendation system is also a silver bullet to attract users, retain users, increase users' stickness or conversionn.

  Who can better use the recommendation system, who can gain more advantage in the fierce competition.

  At the same time, there are many problems in the process of using the recommendation system, such as: huge data, complex model, inefficient distributed training, and so on.

What is PaddleRec ?

• A quick start tool of search & recommendation algorithm based on PaddlePaddle

• A complete solution of recommendation system for beginners, developers and researchers.

• Recommendation algorithm library including content-understanding, match, recall, rank, multi-task, re-rank etc.

Getting Started

Environmental requirements

• Python 2.7/ 3.5 / 3.6 / 3.7

• PaddlePaddle >= 1.7.2

• operating system: Windows/Mac/Linux

  Linux is recommended for distributed training

Installation

1. Install by pip

python -m pip install paddle-rec

This method will download and install paddlepaddle-v1.7.2-cpu. If PaddlePaddle can not be installed automatically，You need to install PaddlePaddle manually，and then install PaddleRec again：

• Download PaddlePaddle and install by pip.
• Install PaddlePaddle by pip，python -m pip install paddlepaddle==1.7.2 -i https://mirror.baidu.com/pypi/simple
• Other installation problems can be raised in Paddle Issue or PaddleRec Issue

2. Install by source code

• Install PaddlePaddle

  python -m pip install paddlepaddle==1.7.2 -i https://mirror.baidu.com/pypi/simple

• Install PaddleRec by source code

  git clone https://github.com/PaddlePaddle/PaddleRec/
  cd PaddleRec
  python setup.py install

• Install PaddleRec-GPU

  After installing PaddleRec，please install the appropriate version of paddlepaddle-gpu according to your environment (CUDA / cudnn)，refer to the installation tutorial Installation Manuals

Quick Start

We take the dnn algorithm as an example to get start of PaddleRec, and we take 100 pieces of training data from Criteo Dataset:

# Training with cpu
python -m paddlerec.run -m paddlerec.models.rank.dnn
