3d ago
Most artificial intelligence today is implemented using some form of neural network. In my last two articles, I introduced neural networks and showed you how to build a neural network in Java. The power of a neural network derives largely from its capacity for deep learning, and that capacity is built on the concept and execution of backpropagation with gradient descent. I'll conclude this short series of articles with a quick dive into backpropagation and gradient descent in Java. To read this article in full, please click here ..read more

1w ago
Oracle’s 2023 per-employee pricing for standard Java is raising concerns about its potential impact on Java licensing costs for customers. The pricing is based on total employee counts, not the number of employees using Java. Published January 23, Oracle’s price list covers the new Java SE Universal Subscription program. The pricing starts at $15 per employee per month for as many as 999 employees, and drops as low as $5.25 per employee per month for 40,000 to 49,999 users. Oracle cited an example in which a company with a total employee count of 28,000, including full-time and part-time emplo ..read more

by
1w ago
Artificial neural networks are a form of deep learning and one of the pillars of modern-day AI. The best way to really get a grip on how these things work is to build one. This article will be a hands-on introduction to building and training a neural network in Java. See my previous article, Styles of machine learning: Intro to neural networks for an overview of how artificial neural networks operate. Our example for this article is by no means a production-grade system; instead, it shows all the main components in a demo that is designed to be easy to understand. To read this articl ..read more

Efforts to improve Java program startup times and performance are set to include improving support for archived Java heap objects in CDS (class data sharing). The plan, made public by Ioi Lam of Oracle in an OpenJDK community RFC last month, aligns with Project Leyden, an effort to improve startup times for Java applications as well as times to peak performance and program footprints. Lam noted that Project Leyden is likely to make extensive use of archived Java heap objects. To read this article in full, please click here ..read more
