● The paper by Kingma and Welling is the seminal paper in this field. They go through the complete building thought process along with its elegant maths. For anyone interested in VAEs, this is a must read: https://arxiv.org/pdf/1312.6114.pdf .

● Another interesting read is the paper by Carl Doersch, A Tutorial on Variational Encoders: https://arxiv.org/pdf/1606.05908.pdf.

● The Github link contains another implementation of VAEs, along with the reproduction of the images from the Kingma and Welling paper: https://github.com/hwalsuklee/tensorflow-mnist-VAE.
