Diverse Application Scenarios

PaddlePaddle powers hundreds of Baidu's and its partners' products.

Computer Vision

Using a Convolutional Neural Network (CNN) for Image Recognition and Object Detection.

Natural Language Understanding

Using a Recurrent Neural Network (RNN) for Sentiment Analysis.

Recommender System

Using Deep Learning on Recommendation Systems to Help Users Find Interests.

Quick Start

Install and make predictions in 5 minutes

Download the trained housing prices model and then install PaddlePaddle on your computer:

pip install paddlepaddle

Instructions on installing pip

Now, create a new file called housing.py, and paste this Python code (make sure to set the right path based on the location of fit_a_line.tar on your computer):

import paddle.v2 as paddle

# Initialize PaddlePaddle.
paddle.init(use_gpu=False, trainer_count=1)

# Configure the neural network.
x = paddle.layer.data(name='x', type=paddle.data_type.dense_vector(13))
y_predict = paddle.layer.fc(input=x, size=1, act=paddle.activation.Linear())

with open('fit_a_line.tar', 'r') as f:
    parameters = paddle.parameters.Parameters.from_tar(f)

# Infer using provided test data.
probs = paddle.infer(
     output_layer=y_predict, parameters=parameters,
     input=[item for item in paddle.dataset.uci_housing.test()()])

for i in xrange(len(probs)):
     print 'Predicted price: ${:,.2f}'.format(probs[i][0] * 1000)

Run python housing.py and voila! It should print out a list of predictions for the test housing data.
