One of the most challenging questions data scientists face is how data can bring value to a specific problem. Before jumping directly into solving a problem using machine learning and AI, it’s important to decide whether that problem is solvable or not.

And to decide this, data analytics comes into the picture. Having the proper insights on your data helps you to obtain the confidence to know that you are ready to engage a machine learning algorithm, hence making it easier to find out the best way to tackle the given problem.

This is the follow-up blog post from my previous article on using Google Analytics for Firebase. While GA allows you to measure and understand user behavior, Crashlytics instead allows you to track and keep a log of all the crashes that have happened on the devices using your app—regardless of whether they choose to report the said crash or not.

In this article we’ll focus on handling errors in Swift.

Proper error handling is crucial to writing effective production-level code that will get shipped with real apps. Often, while working on an app’s features, developers tend to focus on the “HAPPY PATH” (see the diagram below)—but in reality, we can’t ship any app without properly addressing different error scenarios that might occur in our code flows.

This tutorial is the 9th part in the series, ML Kit for Mobile Developers. If you’re not quite caught up, you can start here:

Earlier this year at Google I/O, the team behind Firebase ML Kit announced the addition of 2 new APIs into their arsenal: object detection and an on-device translation.

Displaying images is one of the most common tasks for any Android developer, but it can become challenging to manage for a variety of reasons.

The process requires loading and displaying the image, handling caches and image manipulations, loading the correct size of the image in the memory, handling network requests if you are loading the image from the internet, much testing, and many other nightmares.

Mobile machine learning, relatively speaking, is still in its infancy. While I fully envision a future where hundreds of thousands of mobile apps will seamlessly leverage ML to provide more personalized, responsive, and immersive user experiences, I also recognize that we all have to start somewhere.

Whether you’re a mobile dev who wants to add ML to your toolkit, a hobbyist looking for a new technology to tinker with, or a product manager trying to get a sense of how mobile ML might work within your roadmap, there are some easy ways to jump right in and experiment.

Python magic methods are also known as dunder methods or special methods. But why such dramatic names? They’re used to overwrite or emulate the behavior of built-in functions.

They’re also easy to recognize, as they follow a particular pattern: They have double underscores as prefixes and suffixes. Hence, the name dunder means Double Underscore. They’re referred to as special methods because they add “magic” to your python classes. Common examples are __init__(), __str__(), __call__(), etc. A magic method is generally used to override operations.

This post is a part of a series about feature engineering techniques for machine learning with Python.

You can check out the rest of the articles:

Welcome back! In this post of our series on feature engineering, we’re going to focus on another common issue in most datasets—outliers. Here, we’ll examine what an outlier is and the different methods to handle them, alongside some code snippets. Let’s get started.

Augmented reality is a term we’ve all heard of, but few developers are able to create immersive AR experiences — it often requires 3D design skills that are often missed in software development courses.

Thankfully, Apple’s Reality Composer makes it easy to build quick, immersive experiences without having experience with CAD and 3D modeling. While beginners can start with this tutorial, I strongly recommend checking out my previous tutorial for a more basic look at Reality Composer.

Accessing a device’s calendar in a React Native app can be a bit tricky. Using open source modules like react-native-add-calendar-event is helpful when you’re looking to show a calendar inside a modal or manipulate calendar events (adding, editing, etc).
