While working with a huge list of data, it’s often convenient to quickly go through the list by means of a scrollbar. As a matter of fact, while reading this article itself, you can see a scrollbar on the right side of the page, which you can use to quickly navigate to the end of the page.

This design pattern is quite common, and Android is no exception, as we can easily find numerous examples of scrollbars, especially when the content is being displayed in a list. Y

ou can see some examples of this below:

In the final part of our series (we’ve arrived!) we’ll add some polish to our game. To do this, we’ll refine our level by adding a menu system (main and pause menus), which is a necessary part of any game. We will also add background sound to our game.

Before proceeding forward, a quick recap. We started by learning Unreal basics—how to navigate and create a HUD (heads up display).

We also created some enemy AI and winning and losing mechanisms. We even tested the game on an Android device. These are core components of any mobile side-scroller game. In this final part we’ll polish our game so that it can be presentable.

Deep Learning requires a lot of computations. It typically involves neural network(s) with many nodes, and every node has many connections — which must be updated constantly during the learning. In other words, at each layer of the network, hundreds and thousands of identical artificial neurons perform the same computation.

Therefore, the structure of a neural network fits very well with the kinds of computation that a GPU (Graphic Processing Unit) can efficiently perform — which are designed to compute, in parallel, the same instructions.

Back when I first started using Photoshop, I’d waste hours between classes cropping out pictures of my friends and pasting their faces onto celebrities and teachers. My go-to method was using the Magic Wand tool to select a person, and then creating a crude mask to cut and paste onto another background. This had varying degrees of success and usually resulted in having to manually outline and erase unwanted pixels from my selection.

As mobile application developers, we’re all aware that the app bundle size (APK/IPA) is always a matter of concern. This is especially true when it comes to developing with Xamarin—large bundle sizes is a well-known drawback with Xamarin apps. They can be really heavy! But then the question is, how do you deal with this? Let’s find out!

The TensorFlow Dev Summit 2018 was full of exciting announcements and great tech talks. There’s a lot to digest and you can see the full live stream below.

For this post though, I’ve pulled out just the bits I think are most relevant to edge computing and mobile development using TensorFlow.
