Multiclass Classification on Highly Imbalanced Dataset

Posted on February 28, 2022 by Sandeep Kumar

Multiclass classification is a classification problem where more than two classes are present. It is a fundamental machine learning task which aims to classify each instance into one of a predefined set of classes. For instance, classifying a set of images of animals as dogs, cats or rabbits. Each s...

Implement Non-linear Independent Components Estimation with Tensorflow

Posted on June 1, 2021 by Sandeep Kumar

Non-linear Independent Components Estimation is a normalizing flow-based generative model which is used to learn the probability distribution of the real samples and then generate the new sample data. This algorithm can be categorized as generative models as GAN and VAE but using a different approac...

Basics of Generative Adversarial Network Model

Posted on April 10, 2021 by Sandeep Kumar

Generative Adversarial Network a.k.a GANs is a generative model which is used to generate new samples using training data. The output samples are similar to the training data but not exactly the same as our goal is to generate more diverse data from what we already have. Goal of GANs The distributio...

Understand Types of Environments in Artificial Intelligence

Posted on March 26, 2020 by Sandeep Kumar

The Environment is the surrounding world around the agent which is not part of the agent itself. It’s important to understand the nature of the environment when solving a problem using artificial intelligence. For example, program a chess bot, the environment is a chessboard and creating a room cl...
