A generative adversarial network (GAN) is a deep neural system that is designed to generate fake/synthetic data items. A GAN has a clever architecture made of two neural networks: a generator that creates fake data items, and a discriminator that … Continue reading →

I was chatting with some of my colleagues at work about the topic of ordinal classification, also known as ordinal regression. An ordinal classification problem is a multi-class classification problem where the class labels to predict are ordered, for example, … Continue reading →

The PyTorch code library was designed to enable the creation of deep neural networks. But you can use PyTorch to create simple logistic regression models too. Logisitic regression models predict one of two possible discrete values, such as the sex … Continue reading →

I was in a meeting recently and one of my colleagues briefly described some work he had done at a previous job. He had an enormous set of training data and wanted to train a logistic regression model. Logistic regression … Continue reading →
