To fix the blurred image generation problem in a Variational Autoencoder (VAE), you can follow the following steps:
- Use a more expressive decoder: Increase the complexity of the decoder network.
- Adopt a perceptual loss: Compare high-level features instead of pixel-wise differences.
- Increase latent space capacity: Use a higher-dimensional latent space to capture more detail.
- Use a beta-VAE: Adjust the KL divergence weight (β) for better trade-off between reconstruction and regularization.
Here is the code snippet you can refer to:
In the above code, we are using the following:
- Improved Decoder: Add more layers and neurons.
- Perceptual Loss: Use high-level features instead of pixel-wise losses.
- Latent Space: Increase dimensionality to capture finer details.
- Beta Adjustment: Tune β to balance regularization and detail.
Hence, this approach reduces blurriness and improves generated image quality.
