AntixK/PyTorch-VAE
PyTorch VAE
This project is a deep learning research toolkit and generative model library providing implementations of Variational Autoencoders using the PyTorch framework. It serves as a framework for training and evaluating autoencoder architectures to learn latent representations for data reconstruction and the generation of synthetic data samples.
The toolkit focuses on unsupervised feature learning and generative model training, featuring a system for mapping external configuration files to model hyperparameters to ensure reproducible experimental runs. It includes mechanisms for tracking training progress and monitoring model performance through the visualization of output samples and latent space organization.
The implementation covers core generative architecture components, including encoder-decoder symmetry, latent space bottlenecks, and the reparameterization trick for gradient-based learning. It also utilizes KL-divergence regularization to constrain learned latent distributions.
