AI art analysis from an existing data file

Art Generation GAN

A PyTorch implementation of a Generative Adversarial Network (GAN) for creating artistic images. This project uses deep learning to generate new artwork based on a training dataset of existing art pieces.

Features

• Custom art dataset handling with automatic image preprocessing
• GAN architecture with Generator and Discriminator networks
• Checkpoint saving and loading functionality
• Art generation from trained models
• Progress tracking with real-time loss reporting
• Error handling and graceful interruption

Requirements

• Python 3.x
• PyTorch
• torchvision
• Pillow (PIL)
• CUDA-capable GPU (optional, but recommended for faster training)

Installation

1. Clone this repository
2. Install the required packages:

pip install torch torchvision pillow

Project Structure

• ArtDataset: Custom dataset class for loading and preprocessing art images
• Generator: Neural network for generating new images
• Discriminator: Neural network for discriminating between real and generated images
• Training utilities and checkpoint management
• Art generation functionality

Usage

Training the Model

Place your training images in a directory (default: "part1") and run:

python your_script.py

The script will:

1. Load and preprocess your training images
2. Train the GAN for the specified number of epochs
3. Save checkpoints at regular intervals
4. Generate sample artworks upon completion

Configuration Options

You can modify these parameters in the script:

• num_epochs: Number of training epochs (default: 100)
• batch_size: Batch size for training (default: 32)
• latent_dim: Dimension of the latent space (default: 100)
• lr: Learning rate (default: 0.0002)
• save_interval: Checkpoint saving frequency (default: 10 epochs)

Generating Art

The generate_art function can be used to create new artworks:

generate_art(generator, output_dir="generated_artwork", num_images=10)

Model Architecture

Generator

• Takes random noise as input
• Uses transposed convolutions for upsampling
• Includes batch normalization and ReLU activations
• Outputs 64x64 RGB images

Discriminator

• Processes 64x64 RGB images
• Uses convolutional layers
• Includes LeakyReLU activations and batch normalization
• Outputs probability of input being real

Error Handling

The script includes robust error handling for:

• Image loading failures
• Training interruptions
• General exceptions

Output

Generated artwork will be saved in the specified output directory (default: "generated_artwork") as PNG files.

Checkpoints

Checkpoints are automatically saved:

• At specified intervals during training
• In the "checkpoints" directory
• Include both Generator and Discriminator states
• Can be used to resume training or generate art

Performance Notes

• Training time varies based on dataset size and hardware
• GPU acceleration recommended for optimal performance
• Memory usage scales with batch size
