  Autoencoders are a class of artificial neural networks which have gained a
lot of attention in the recent past. Using the encoder block of an autoencoder
the input image can be compressed into a meaningful representation. Then a
decoder is employed to reconstruct the compressed representation back to a
version which looks like the input image. It has plenty of applications in the
field of data compression and denoising. Another version of Autoencoders (AE)
exist, called Variational AE (VAE) which acts as a generative model like GAN.
Recently, an optimizer was introduced which is known as lookahead optimizer
which significantly enhances the performances of Adam as well as SGD. In this
paper, we implement Convolutional Autoencoders (CAE) and Convolutional
Variational Autoencoders (CVAE) with lookahead optimizer (with Adam) and
compare them with the Adam (only) optimizer counterparts. For this purpose, we
have used a movie dataset comprising of natural images for the former case and
CIFAR100 for the latter case. We show that lookahead optimizer (with Adam)
improves the performance of CAEs for reconstruction of natural images.
