PixelCNN is a type of computer model that is used to create images by breaking them down into individual pixels. This technique makes it faster and easier to create large datasets of images compared to other methods.
How Does PixelCNN Work?
PixelCNN works by taking an image and breaking it down into individual pixels. It then analyzes each pixel, one at a time, to determine what the next pixel should be based on the previous ones. This process is known as autoregression. The model uses convol
What is PresGAN?
PresGAN, short for Prescribed Generative Adversarial Networks, is a type of machine learning algorithm that is used for generating synthetic data or images. It adds noise to the output of a density network and optimizes an entropy-regularized adversarial loss to stabilize the training procedure. The entropy regularizer encourages PresGANs to capture all the modes of the data distribution.
The goal of PresGAN is to generate synthetic data that looks as close to the original dat
What is ProGAN?
ProGAN stands for Progressively Growing GAN, which is a type of machine learning algorithm. Specifically, it is a type of generative adversarial network (GAN) that uses a progressively growing training approach to generate high-quality images. Essentially, ProGAN is designed to create images that look like they were made by humans, even though they were actually generated by a computer.
How Does ProGAN Work?
The main idea behind ProGAN is to train the generator and discrimina
RealNVP: A Generative Model for Density Estimation
What is RealNVP?
RealNVP is a generative model that utilizes real-valued non-volume preserving (real NVP) transformations for density estimation. This model is used to generate or simulate a new set of data, given a set of training data. The idea behind a generative model is to mimic the distribution of the training data points and then use this distribution to generate new data. This method is often used in deep learning to create artificial
An autoencoder is a type of neural network that is trained to learn a compressed representation of data, typically for the purpose of dimensionality reduction or feature extraction. Essentially, it learns to encode the input data into a low-dimensional representation and then decode it back into its original form. By doing so, it can identify patterns and correlations within the data that may not be readily apparent in the raw data.
What is RAE?
RAE stands for "Regularized Autoencoder" and re
Restricted Boltzmann Machines
Restricted Boltzmann Machines, or RBMs, are types of neural networks that can learn to represent probability distributions over inputs. RBMs are used in various applications such as dimensionality reduction, feature learning, collaborative filtering, and generative modeling.
How RBMs Work
RBMs have two layers of nodes, the visible layer and the hidden layer. Nodes in the visible layer represent the inputs, while nodes in the hidden layer represent latent feature
The Sliced Iterative Generator (SIG) is an advanced generative model that employs a Normalizing Flow and Generative Adversarial Networks techniques to create an efficient and accurate likelihood estimation. Unlike other deep learning algorithms, this approach uses a patch-based approach that helps the model scale well to high dimensions.
SIG is designed to optimize a series of 1D slices of data space, enabling it to match probability distribution functions of data samples across each slice in a
A sparse autoencoder is a popular type of neural network that uses sparsity as a way to compress information. The idea behind an autoencoder is to take data, like an image or a sequence of numbers, and create a compressed representation that can later be used to reconstruct the original data.
What is an Information Bottleneck?
One of the challenges with autoencoders is to find the right balance between compression and reconstruction accuracy. If we compress the data too much, it becomes hard
Overview of SNGAN:
SNGAN, or Spectrally Normalised GAN, is a powerful type of generative adversarial network that can be used to generate images, videos, and other types of media. It is a type of neural network that is composed of two parts: a generator and a discriminator.
The generator works to create and output new data that is based on the patterns and features that it has learned from the training data. The discriminator, on the other hand, works as a classifier to determine whether the g

Viewmaker Network is a type of generative model that learns to produce input-dependent views for contrastive learning. This means that it creates different views of an image to help a neural network learn how to distinguish between different images. The network is trained alongside an encoder network and works by creating views that increase the contrastive loss of the encoder network, which helps the neural network learn more effectively.
