Data Science Lessons

In this blog, we are going to see Generative adversarial networks (GAN). A generative adversarial network is a class of machine learning frameworks used for training generative models. Generative models create new data instances that resemble the training data. Given a training set, a GAN learns to generate new data with the same statistics as the training set. GANs much depend on the training loss of the model, the model tries to minimize loss to generate as real images as possible.

GAN is a  generative model which achieves a high level of realism by pairing a generator with a discriminator. The generator learns to produce the ...

PyTorch is the fastest growing deep learning framework and it is also used by many top fortune companies like Tesla, Apple, Qualcomm, Facebook, and many more. It integrates many algorithms, methods, and classes into a single line of code to ease your day. PyTorch has many optimizer classes such as AdaDelta, Adam, and SGD to name a few. The optimizer takes the parameters we want to update, the learning rate we want to use and optimizers update weights through its step() method. In this blog, we are going to see 13 such optimizers which are supported by the PyTorch framework.
