Training Logistic Regression with Cross-Entropy Loss in PyTorch

In the previous session of our PyTorch series, we demonstrated how badly initialized weights can impact the accuracy of a classification model when mean square error (MSE) loss is used. We noticed that the model didn’t converge during training and its accuracy was also significantly reduced. In the following, you will see what happens if […]

Using Autograd in PyTorch to Solve a Regression Problem

We usually use PyTorch to build a neural network. However, PyTorch can do more than this. Because PyTorch is also a tensor library with automatic differentiation capability, you can easily use it to solve a numerical optimization problem with gradient descent. In this post, you will learn how PyTorch’s automatic differentiation engine, autograd, works. After […]

Making Predictions with Logistic Regression in PyTorch

Logistic regression is a statistical technique for modeling the probability of an event. It is often used in machine learning for making predictions. We apply logistic regression when a categorical outcome needs to be predicted. In PyTorch, the construction of logistic regression is similar to that of linear regression. They both applied to linear inputs. […]

Training a Multi-Target Multilinear Regression Model in PyTorch

The multi-target multilinear regression model is a type of machine learning model that takes single or multiple features as input to make multiple predictions. In our earlier post, we discussed how to make simple predictions with multilinear regression and generate multiple outputs. Here we’ll build our model and train it on a dataset. In this […]

Multi-Target Predictions with Multilinear Regression in PyTorch

While in the previous few tutorials we worked with single output multilinear regression, here we’ll explore how we can use multilinear regression for multi-target predictions. Complex neural network architectures are essentially having each neuron unit to perform linear regression independently then pass on their result to another neuron. Therefore, knowing how such regression works is […]

Training a Single Output Multilinear Regression Model in PyTorch

A neural network architecture is built with hundreds of neurons where each of them takes in multiple inputs to perform a multilinear regression operation for prediction. In the previous tutorials, we built a single output multilinear regression model that used only a forward function for prediction. In this tutorial, we’ll add optimizer to our single […]

Training a Linear Regression Model in PyTorch

Linear regression is a simple yet powerful technique for predicting the values of variables based on other variables. It is often used for modeling relationships between two or more continuous variables, such as the relationship between income and age, or the relationship between weight and height. Likewise, linear regression can be used to predict continuous […]
