AWS DeepComposer, a creative way to get started with machine learning, was launched in preview at AWS re:Invent 2019. Today, I’m extremely happy to announce that DeepComposer is now available to all AWS customers, and that it has been expanded with new features.
A primer on AWS DeepComposer
If you’re new to AWS DeepComposer, here’s how to get started.
Now let’s look at the new features, which make it even easier to get started with generative AI.
DeepComposer is powered by Generative Adversarial Networks (aka GANs, research paper), a neural network architecture built specifically to generate new samples from an existing data set. A GAN pits two different neural networks against each other to produce original digital works based on sample inputs: with DeepComposer, you can train and optimize GAN models to create original music.
Until now, developers interested in growing skills in GANs haven’t had an easy way to get started. In order to help them regardless of their background in ML or music, we are building a collection of easy learning capsules that introduce key concepts, and how to train and evaluate GANs. This includes an hands-on lab with step-by-step instructions and code to build a GAN model.
Once you’re familiar with GANs, you’ll be ready to move on to training your own model!
You now have the ability to train your own generative model right in the DeepComposer console, without having to write a single line of machine learning code.
First, let’s select a GAN architecture:
Let’s go with MuseGAN, and give the new model a name.
Next, I just have to pick the dataset I want to train my model on.
Optionally, I can also set hyperparameters (i.e. training parameters), but I’ll go with default settings this time. Finally, I click on ‘Start training’, and AWS DeepComposer fires up a training job, taking care of all the infrastructure and machine learning setup for me.
About 8 hours later, the model has been trained, and I can use it to generate compositions. Here, I can add the new ‘rhythm assist’ feature, that helps correct the timing of musical notes in your input, and make sure notes are in time with the beat.
AWS DeepComposer is available today in the US East (N. Virginia) region.
The service includes a 12-month Free Tier for all AWS customers, so you can generate 500 compositions using our sample models at no cost.
