PyTorch Introduction — Constructing your First Linear Mannequin | by Ivo Bernardo | Dec, 2023

Discover ways to construct your first PyTorch mannequin, through the use of the “magical” Linear layer

Regression Mannequin — Picture generated by AI

In my final weblog put up, we’ve realized how to work with PyTorch tensors, an important object within the PyTorch library. Tensors are the spine of deep studying fashions so naturally we are able to use them to suit easier machine studying fashions to our datasets.

Though PyTorch is thought for its Deep Studying capabilities, we’re additionally in a position to match easy linear fashions utilizing the framework — and that is really top-of-the-line methods to get aware of the torch API!

On this weblog put up, we’re going to proceed with the PyTorch introduction collection by checking how we are able to develop a easy linear regression utilizing the torch library. Within the course of, we’ll find out about torch Optimizers, Weights and different parameters of our studying mannequin, one thing that might be extraordinarily helpful for extra complicated architectures.

Let’s begin!

For this weblog put up, we’ll use the music reputation dataset the place we’ll need to predict the recognition of a sure music based mostly on some music options. Let’s take a peek on the head of the dataset under:

songPopularity = pd.read_csv(‘./knowledge/song_data.csv’)

Among the options of this dataset embody fascinating metrics about every music, for instance:

  • a stage of music “power”
  • a label encoding of the important thing (for instance, A, B, C, D, and so forth.) of the music
  • Track loudness
  • Track tempo.

Our purpose is to make use of these options to foretell the music reputation, an index starting from 0 to 100. Within the examples we present above, we’re aiming to foretell the next music reputation:

As a substitute of utilizing sklearn, we’re going to use PyTorch modules to foretell this steady variable. The nice a part of studying the right way to match linear regressions in pytorch? The information we’re going to assemble may be utilized…
