About The Project

This project refers to the implementation of one personal project for approaching the Generative AI field. The idea is to gain experience with Generative Adversarial Network models and in particular on Wasserstrein GAN with gradient penalty. This variant allows a more stable training procedure, get rids of some problems like mode collapse and provides a meaningful loss function interpretation. The final application's purpose is to generate synthetic images given a food category.
In details the NN architectures and the hyperparameters used are taken from different popular parers cited in References section while instead, the developement is realized with famous frameworks like Pytorch and Lighting Fabric written also in Built With section.

Getting Started

This is an example of how you may give instructions on setting up your project locally. To get a local copy up and running follow these simple example steps.

Prerequisites

This is an example of how to list things you need to use the software and how to install them.

pip install torch torchvision torchaudio #--index-url https://download.pytorch.org/whl/cu117
pip install lightning
pip install matplotlib
pip install pandas
pip install numpy
pip install streamlit

Installation

1. Clone the repo

   git clone https://github.com/MrCosta57/food_gan.git

2. Enter your configuration in config.py

3. Before run the streamlit GUI you must place some model checkpoint in checkpoints/ directory or train the model from scratch

Usage / Demo

You can run one .ipynb file or

streamlit run app.py

Roadmap / Future work

• Base project structure
• GAN implementation using parameters and convolutional architectures from different papers
• Train model for more epochs and trying different parameters
• Trying other discriminator/generator architecture or model

See the open issues for a full list of proposed features (and known issues).
