It’s often the case that companies want to implement machine learning for a given task—let’s say, to perform classification on data—but are cursed with the problem of having insufficient or unreliable labels for that data.

In these cases, companies could opt to hand label their data, but hand labelling can be a demanding task that could also lead to human bias or significant errors. What if it’s the case that you have labelled data for your positive class, but you have unreliable labels for your negative class? How do you get around this problem?

If you’ve been following my blogs lately, you might have noticed that I’ve been writing a lot on edge machine learning, for both mobile and desktop.

While building models and writing code that runs inference on them is one thing, it’s equally important to also package your solution in a way that lets your end-users actually use them.

PoseNet is a deep learning TensorFlow model that allows you to estimate and track human poses (known as “pose estimation”) by detecting body parts such as elbows, hips, wrists, knees, and ankles.

It uses the joints of these body parts to determine body postures. Nowadays, many industries use this kind of technology in order to improve work efficiency, and in technologies such as augmented reality experiences, animation & gaming, and robotics. The evolution of human-like robots, virtual gaming experiences, motion tracking, and body movement interpretations can be done with the use of these types of high-end PoseNet deep learning models.

Computer vision is a branch of deep learning that focuses on the utilization of deep neural networks to model problems from images. In this article, we’ll be looking at how we can apply computer vision as a tool for football analytics.

Football is a sport that involves 2 teams; with each team having 11 players and a goalkeeper. Here are some analytics that could be explored from football games using AI.

Creating accurate machine learning models capable of identifying multiple faces (or other target objects) in a single image remains a core challenge in computer vision, but now with the advancement of deep learning and computer vision models for mobile, you can much more easily detect faces in an image.

In this article, we’ll do just that on Android with the help of Google ML Kit’s Face Detection API.

Today we’re announcing a partnership with ModelDepot to provide pre-trained machine learning models converted specifically for use in mobile apps. Three newly-converted models are now available in Core ML format for use in iOS applications. This is just the start, and over time we’ll add additional models and additional ML platforms.

Skin care is a really personal thing. But there are significant roadblocks in the way of accessing treatment. From a shortage of dermatologists (a recent study found there were just over 3 per 100,000 people), to cost-prohibitive treatment options, people struggling with skin conditions often have nowhere to turn.

OpenCV is a powerful tool for doing intensive operations in real-time, even for resource-limited mobile devices. Throughout a couple of tutorials, we’re going to create an Android app that applies various effects to images.

In part 1 of the series, we discussed horizontal and vertical image stitching:

This tutorial will explore creating a cartoon image effect by reducing the number of colors representing the image using lookup tables (LUTs). The sections covered in this tutorial are as follows:

Phone authentication allows a user to sign in to a mobile app using their phone number. This could be done traditionally by associating a password with a user and storing it when the user first registers with the app.
