At the heart of any machine learning initiative is data—it’s required to train models and serves as the base on which models are applied.

It follows, then, that to effectively train and implement machine learning models, you must have good data. Unfortunately, curating high-quality data often isn’t an easy task.

This article explains how open source dataset initiatives contribute to the development of machine learning models. You’ll also learn about popular open source dataset initiatives for machine learning, and discover what challenges to expect when using publicly-available data.

If I gave you 30 minutes and a reasonably powerful computer, you could train a machine learning model to recognize dozens of breeds of dogs with higher accuracy than most humans.

This is partially due to great tools and frameworks like TensorFlow or PyTorch, but it’s also due to the availability of data. At some point, generous researchers decided to take the time to label a few thousand images of pets and release that data publicly.

Try to train a similar model for species of fish, and you’ll find yourself spending weeks or thousands of dollars sourcing and labeling data yourself.

Introduction

In this post, I’ll explore how I made a Lens that features an animated phoenix flying through an AR scene anchored to the ground. This is the finished Lens:

To get there, we will leverage the Refinement Pack and Particles template from Lens Studio, as well as a 3D phoenix asset from Sketchfab.

Specifically, this post will cover:

Moving an object along a 3D path through the scene using a Prefab from the Refinement Pack Applying a texture to a 3D model of a phoenix downloaded from Sketchfab Working with particle emitters to add a stationary column of smoke, embers throughout the scene, and a bokeh effect that follows the phoenix

Let’s dive in!

Before we begin, let’s get started by answering the following question:

What is a type?

The answer to this question is fairly simple—a type is a collection of related data that encapsulates certain concepts and principles. A type can be abstract or concrete, it defines a set of valid operations that we can perform on it, and finally, a type clearly demarcates the internal and external.

In this series, we’re learning about SwiftUI by making a profile page. And so far, we’ve accomplished a very simple—yet stylish—profile for ourselves in just a few paragraphs of code!

Gesture recognition helps us to know the meaning of human body movement, including the movement of hands, head, arms, face, or body. Today’s world is observing huge advances in visualization displays and this includes object trackers in AR applications.

The main purpose of this article is to explore gesture recognition in Facebook’s Spark AR Studio for an efficient human-computer interaction. It presents a method for tracking hand gestures and recognizing hand gestures by extracting unique invariant features from gestures.
