I love Swift Playgrounds, I really do. That’s why it was time to pick up my Playgrounds repository again to add some new features (along with adapting it to Swift 4).

This particular Playground is an intro to Microsoft Azure’s Cognitive Services — and I really fell in love with the emotion detection feature 😍. So I decided that it’s time to get my hands dirty with the Custom Vision Service.

The Computer Vision API is already in the Playground, which tells you what’s on a picture and gives you a proper description of it. But the underlying model is trained quite broadly and with general terms, so detecting very specific things is quite difficult…like, for instance, cat emotions!

Computers’ ability to have a deep understanding of images has given us the power to use them to extract information from images in an automated manner. A technique as simple as thresholding can extract enough information to be used in different applications.

More advanced algorithms can extract much complex information about the context and the content of images, such as classification and detection.

Neural network quantization is a process of reducing the precision of the weights in the neural network, thus reducing the memory, computation, and energy bandwidths.

Particularly when deploying NN models on mobile or edge devices, quantization, and model compression in general, is desirable and often the only plausible way to deploy a mobile model as the memory and computational budget of these devices is very limited.

The Model Maker library makes the process of developing TF Lite models quick and easy. It also allows you to adopt different architectures for your models.

The process of exporting the TF Lite models is also straightforward. Let’s take a look at how you can do that for image classification models.

The recent improvements in the field of speech synthesis have lead to many innovative technologies, offering a wide range of useful applications like automatic speech recognition, natural speech synthesis, voice cloning, digital dictation, and so forth.

Deep learning has played an immensely important role in improving already existent speech synthesis approaches by replacing the entire pipeline process with neural networks trained on data alone.

Building a machine learning model to identify custom images might require a lot of dataset collection and a lot of time to do it correctly.

This article is not a theoretical one—rather, I’ll walk you through the steps for creating an app that you could distribute amongst your peers to collect, create, and analyze TensorFlow models.

If you want a custom image classifier, but don’t have the right data or the know-how to build it, you’ve come to the right place.

Computer scientists have been attempting to solve many different Natural Language Processing (NLP) problems since the time computers were conceived.

But the field become slightly stagnant around the 2000s, and did not gain traction again till the ‘Deep Learning’ boom that occurred during the last decade.

Of the many factors that helped build this traction was the spike in available textual data, thanks to the rise in the number of web and mobile applications.

Adding a colorful gradient is a great way to build backgrounds and create even more impressive filters. In Facebook’s Spark AR Studio, we use the Patch Editor to create color gradients.

In this article, we will learn to create a colorful gradient, add a gradient to the whole scene, and to a distance field shape. Follow the steps below to create colorful gradients in the Patch Editor.
