One way to get a diverse set of classifiers is to use very different training algorithms,as just discussed. Another approach is to use the same training algorithm for everypredictor but to train them on different random subsets of the training set. Whensampling is performed with replacement, this method is called bagging1(short for bootstrap aggregating). When sampling is performed without replacement, it is called…...

Amazon EFS, Amazon EBS, and Amazon S3 are AWS’ three different cloud storage types that can be applied for different types of workload needs. Let’s take a closer look at the key features of each option, as well as the similarities and differences. Amazon EBS delivers high-availability block-level storage volumes for Amazon Elastic Compute Cloud (EC2) instances. It stores data on a file system which is retained after the EC2 instance is shut down....

In this post, we will discuss why it is important to override equals and hashCode method in Java/Kotlin. Item 9 in Josh Bloch’s Effective Java suggests always override hashCode() method if the class overrides equals(). In this post, we will discuss why this is necessary and good practice. We know that two objects are considered equal only if their references point to the same object and unless we override ...

Room provides an abstraction layer over SQLite to allow fluent database access while harnessing the full power of SQLite. Because Room takes care of several concerns for you, e.g. caching, networking, Android highly recommend using Room instead of SQLite. If you are coming from iOS, the good news is that Room is very similar to the core data in iOS development....

Pong game (prototype) In this article, we recreate the two-player game Pong - the first arcade video game 1972 - for Android using Kotlin. We will implement the game SurfaceView, game loop design pattern, and code optimization for better performance. Game loop Game loop is a common design pattern in game development. It is already integrated into different game engines. Nevertheless, we won't use one in this project. [ 1,047 more word ]
