TSNE-Embedding-Visualisation

A Simple and easy to use way to Visualise Embeddings! Blog post on this project is here.

Visualising Example

What this project is?

This project is forked from Tensorflow's Standalone Embedding Projector. It shows how a pretrained InceptionV3 model can be used on images and plotted in an interactive 3d map.

Why this over the Standalone Projector?

This project allows you to visualise any array of vectors with a light depency stack. It is designed to be decoupled from any library. Moreover , it uses a static file system, so you can publish your results without requiring a server. E.g. https://harveyslash.github.io/TSNE-Embedding-Visualisation/.

Project Structure

|-- data  <-- where to put raw data
|-- Feature-extractor.ipynb <-- Demo of Embedding generation in a step by step fashion
|-- index.html <-- The GUI of the Viewer (Do not touch, unless you know what youre doing)
|-- LICENSE
|-- main.py <-- Executable to generate embedding data from command line args
|-- oss_data <-- required by the visualisation project
|   |-- oss_demo_projector_config.json <-- all configuration files are stored here, this is modified by main.py automatically
|   |-- sprites.png <-- sprites for the demo 
|   `-- tensor.bytes <-- embeddings array for the demo
`-- requirements.txt

Installation and requirements

This project requires python3.6. You can install all dependencies using pip install -r requirements.txt

Usage

Usage: main.py [OPTIONS]

Options:
  --data TEXT                 Data folder,has to end with /
  --name TEXT                 Name of visualisation
  --sprite_size INTEGER       Size of sprite
  --tensor_name TEXT          Name of Tensor file
  --sprite_name TEXT          Name of sprites file
  --model_input_size INTEGER  Size of inputs to model
  --help                      Show this message and exit.

Visualising

After you have run main.py, the sprites, tensors, and config.json should be updated. You can then serve the visualisation using a static file server. I just run python -m SimpleHTTPServer at the root level of the project. You can also upload the files to a github repository and then view it using github pages.
