Google Sketcher

This repo is dedicated to build a simple yet effective Convolutional Neural Network, train it over the Google Quick-Draw Dataset, and save it for further usage.

You can find a demo from here.

Description

The trained CNN can take any doodle image as input, and "guess" what the doodle describes within 345 categories.

  • CNN Architecture v1:
    cnn_architecture_v1

  • CNN Architecture v2:
    cnn_architecture_v2

  • Manual:

  1. run python3 main.py - The script will automatically download training dataset, prerpocess data, build the CNN, train the CNN, and save the model.
  2. run pip3 install tensorflowjs - The command will automatically install the latest version of TensorFlowJS into your machine.
  3. run bash convert.sh - The script will automatically convert the trained model into a TensorflowJS compatible model, so that we can use the trained model to do inference on a web application.

Trained Model

  • You can find my trained model in the model directory.
  • You can also download the trained model and the training log file in my AWS S3.
