C\# - Support Vector Machines Using C\#


Support Vector Machines Using C#

James McCaffrey

A support vector machine (SVM) is a software system that can make predictions using data. However, implementing a support vector machine is quite complex and difficult. James McCaffrey presents a complete working example of an SVM that will help you gain a good understanding of exactly how SVMs work and help you be able to use a library implementation.

Neural Regression Using PyTorch

James McCaffrey

The goal of a regression problem is to predict a single numeric value. Using a demo program, James McCaffrey shows how to create a prediction model based on the Boston Housing dataset. The demo creates and trains a neural network, then makes a prediction about the median house price in a test town.
